Steel structures are highly favored for their lightness, high strength, and aesthetic appeal, making them widely used in large-scale architectural steel structures. However, as time passes and the load increases, the stability of steel structures becomes crucial. This article will explore the importance and methods of prefabricated steel structure building reinforcement, helping readers understand this critical civil engineering issue.   The Necessity and Classification of Steel Structure Reinforcement When steel structures face insufficient load-bearing capacity or damage, reinforcement and strengthening are required. Reinforcement work should be carried out after professional inspection, and measures should be taken based on the extent of the damage, either locally or as a whole. There is a variety of reinforcement techniques, including adding supports, changing structural calculation diagrams, adhesive reinforcement, and prestressed reinforcement, among others.   The method of adding supports involves installing additional supports in the middle of beams or slab spans to reduce the span and increase load-bearing capacity, while also limiting deflection. This method is suitable for large-span steel structures but may affect the use of space. Changing the steel structural calculation diagram involves improving steel structural stability and load-bearing capacity through measures such as changing load distribution and adding supports. Adhesive reinforcement of steel structures uses adhesives to bond materials to damaged areas, reducing stress and offering advantages such as not increasing self-weight, fatigue resistance, and corrosion resistance. Adhesive fiber-reinforced plastic reinforcement is suitable for various steel structural components and has characteristics such as resistance to corrosion and moisture, but requires fireproof treatment. Prestressed reinforcement technology for prefabricated steel structure buildings includes direct bonding and overall reinforcement methods, suitable for the reinforcement of components or the entire structure.   Advantages and Challenges of Steel Structure Reinforcement Techniques The selection of steel structure reinforcement techniques must consider economic efficiency, efficiency, and reliability. Prestressed reinforcement technology is favored because it can be carried out without unloading or production shutdown, reducing deformation and eliminating stress beyond the limit. It also reduces the stress of bond interface delamination, improving the reliability of reinforcement and reducing costs.

In the realm of industry, the issue of metal part corrosion has long been a thorn in our side. Not only does it lead to a decline in equipment performance, but it can also trigger safety incidents and increase maintenance costs. Fortunately, with the advancement of technology, research on new anti-corrosion additives has provided us with solutions. We will explore how these new anti-corrosion additives significantly enhance the rust-proofing performance of metal silos and steel structures.   The Challenge of Rust for Metal Silos and Steel Structures Metal silos and steel structures are widely used in construction and industry due to their strength and durability. However, they also face the serious challenge of corrosion. Corrosion not only affects the integrity of the structure but can also lead to material loss and environmental pollution. Therefore, developing effective anti-corrosion additives is crucial for extending the service life of these structures.   Advances in Research on New Anti-Corrosion Additives The latest research indicates that sulfonate-based anti-corrosion agents with different alkalinity values show significant differences in rust prevention performance. By delving into the mechanisms of sulfonate rust prevention, scientists have been able to design more efficient formulas for anti-corrosion composites. These composites not only provide stronger protection against rust but also adapt to various working environments and requirements.   Impact on Metal Components The impact of new anti-corrosion additives on metal components or metal fabrication parts is remarkable. They can form a protective layer on the metal surface, isolating it from water and oxygen, thus slowing down the corrosion process. Moreover, these additives are also penetrating, capable of reaching into the tiny cracks in the metal surface to remove existing rust and corrosion.   Specific Impact on Metal Silos and Steel Structures For metal silos and steel structures, the application of new anti-corrosion additives can significantly improve their durability and safety. They can form a uniform protective layer on the surface of these structures, reducing the decrease in structural strength and maintenance costs caused by corrosion. In addition, the environmentally friendly nature of these additives means that they do not impose additional burdens on the environment during use.   Research and application of new anti-corrosion additives offer new solutions for the maintenance of metal silos and steel structures. They not only extend the service life of these structures but also enhance their safety and environmental friendliness. As research progresses, we have every reason to believe that these new additives will play an increasingly important role in the field of industrial rust prevention.

Today's world stainless steel stands out for its durability and resistance to corrosion, making it a top choice for manufacturing silo bins and metal fabrication parts. However, as technology advances, so do our demands for materials. Today, a new generation of stainless steel that has made a quantum leap in corrosion resistance—enter micro-alloyed Si-enhanced ferritic/martensitic steels and austenitic stainless steels.   The Limitations of Traditional Stainless Steel Traditional stainless steels, such as 9%-12% chromium ferritic/martensitic steels and 316 austenitic stainless steels, have performed admirably in many applications. However, in extreme environments like liquid lead-bismuth eutectic (LBE), their performance can be challenged. LBE is highly corrosive, posing a severe threat to the stability and longevity of containers and components.   The Breakthrough with New Stainless Steel The latest research indicates that by employing micro-alloying techniques, specifically adding a small amount of silicon (Si), we can significantly enhance the stability and mechanical properties of materials in LBE. These new materials include 9Cr-Si and 12Cr-Si ferritic/martensitic steels, as well as ASS-Si austenitic stainless steels.   A Leap in Corrosion Resistance The secret to these new stainless steel materials lies in the formation of silicon-rich oxides in LBE. These oxides not only increase the density of the oxide film but also markedly improve the material's corrosion resistance. At 550°C, whether in static saturated oxygen or dynamic controlled oxygen LBE environments, the dissolution corrosion of these materials is effectively suppressed.   Impact on Stainless Steel Fabrication Services and Stainless Steel Storage Tank What does this mean for stainless steel fabrication services and stainless steel storage tank? Firstly, these new materials offer enhanced protection, significantly extending the service life of stainless steel fabrication services and stainless steel storage tank in highly corrosive environments. Secondly, due to their superior corrosion resistance, these materials are poised to meet the design requirements of advanced nuclear reactors like lead-cooled fast reactors, offering new solutions for nuclear safety and efficiency.   As new materials continue to emerge, the horizons for stainless steel applications expand. Micro-alloyed Si-enhanced ferritic/martensitic steels and austenitic stainless steels, with their exceptional corrosion resistance, are opening a new chapter in the application of stainless steel.

Steel products are ubiquitous in our daily lives, from architectural structures to household appliances, and industrial equipment. They are an essential part of our existence. However, a significant issue with steel products is their susceptibility to corrosion, especially in acidic environments. Corrosion not only affects their appearance but also reduces structural integrity, potentially leading to safety hazards. Therefore, finding effective corrosion inhibitors is crucial for extending the lifespan of steel products for example steel silo, steel skip bin or steel structure. Research has discovered a natural corrosion inhibitor—Erigeron Canadensis extract (ECE)—to see how it becomes the green guardian of steel products.   Erigeron Canadensis L., also known as Canadian daisy fleabane, has extracts rich in flavonoids, alkaloids, and terpenes, making it a potential corrosion inhibitor. The active components in ECE contain a multitude of heteroatoms and unsaturated structures, which enable ECE to form a protective film on the steel surface. In HCl medium, the protonated components of ECE carry a positive charge, while the steel surface, due to the adsorption of Cl-, carries a negative charge. The opposite charges attract each other, allowing ECE to physically adsorb onto the steel surface and form a protective layer. Additionally, the O atoms in ECE coordinate with the empty d orbitals of Fe, forming chemical adsorption that further enhances the stability of the protective film.   Studies have shown that ECE exhibits good corrosion inhibition performance on steel in a 1.0 mol/L HCl medium, with the corrosion inhibition rate increasing as the concentration of ECE increases. At 40°C, the best corrosion inhibition rate is achieved with 300 mg/L of ECE, reaching 93.7%. This means that using Erigeron Canadensis extract can significantly reduce the corrosion rate of steel in acidic environments.   For steel products like steel feeding silos and waste skip bin that are often exposed to harsh environments, the application of ECE can significantly improve their corrosion resistance. By forming a protective film on the surface of these products, ECE not only slows down corrosion but also enhances surface hydrophobicity, thereby reducing contact with water and corrosive media, and extending service life.   As a natural and eco-friendly corrosion inhibitor, Erigeron Canadensis extract not only effectively protects steel products from corrosion but also enhances their hydrophobicity, which is significant for increasing the lifespan and safety of steel products. With the growing emphasis on environmental protection and sustainable development, the application prospects of Erigeron Canadensis extract are broad, and it is expected to become a rising star in the field of steel anti-corrosion.

What Are Vapor Phase Inhibitors? Vapor Phase Inhibitors (VPIs) are low molecular weight compounds that volatilize and adsorb onto metal fabrication parts surfaces to form a protective film, preventing contact between the metal and corrosive media. Unlike traditional corrosion protection methods, VPIs don't need direct contact with the metal part surface to protect every nook and cranny, including hard-to-reach areas like inner cavities, pipes, grooves, and gaps. They are particularly suitable for non-coating protection of complex custom metal fabrication products and components.   How Do Vapor Phase Inhibitors Work? VPIs work by volatilizing and adsorbing on the metal surface to form a protective film that isolates the metal from corrosive media. They can physically or chemically adsorb on the metal surface, creating a hydrophobic layer that prevents water molecules and corrosive media from contacting the metal. Depending on the adsorption method and mechanism, VPIs are classified as anodic, cathodic, or mixed types, each inhibiting the corrosion process in different ways.   Environmentally Friendly Characteristics of Vapor Phase Inhibitors With the rise of environmental awareness, the research, development, and application of low toxicity or non-toxic VPIs have accelerated. These new inhibitors not only have minimal environmental impact during extraction, synthesis, and application but also provide effective corrosion protection. For instance, inhibitors extracted from natural plants and marine animals are not only eco-friendly but also highly effective.   Application Prospects of Vapor Phase Inhibitors Due to their efficiency, economy, ease of use, and long-lasting protection, VPIs have been widely applied in various fields such as machinery, military, and chemical industries. As research on new VPIs progresses, more products are expected to become commercialized and applied in practice, especially in the development of general and efficient VPIs, low toxicity and green VPIs, research on VPIs formulation, and the development of new testing techniques that combine thin film conditions to understand the mechanism of VPIs.   Vapor Phase Inhibitors, as an emerging technology in metal corrosion protection, are becoming an important choice in the field with their unique advantages and broad application prospects. With advancements in technology and increasing environmental requirements, research and application of VPIs will continue to deepen, providing more reliable and environmentally friendly protection for metal products.

Amidst the wave of industrial automation, the emergence of new technologies is continuously driving innovation in traditional industries. Today, we introduce a new type of robot—the cement silo cleaning robot—that is revolutionizing the field of silo cleaning for powdered materials like cement and fly ash with its unique functions and efficiency.   One of the core functions of the cement silo cleaning robot is to enhance the efficiency of powder silo cleaning. Traditional manual cleaning methods are time-consuming and labor-intensive, whereas robots can work around the clock, significantly reducing the cleaning cycle. The automated operation of the robot reduces delays caused by human factors, ensuring the continuity and timeliness of cleaning work, thereby improving the efficiency of the entire production process. Besides, robots perform tasks through remote control or preset programs, reducing the need for personnel to enter high-risk areas, lowering operational risks, and ensuring the safety of workers.   While reducing material loss, the cement silo cleaning robot also minimizes dust spillage caused by improper cleaning, which is significant for environmental protection. The reduction of dust not only lightens pollution to the surrounding environment but also decreases the health impact on workers. Additionally, the automated cleaning process reduces labor costs, saving expenses for companies and achieving dual goals of economic benefits and environmental protection.   Modern cement silo cleaning robots are often equipped with sensors and data collection systems that can monitor the condition inside the silos in real-time and gather relevant data. This data can be used to analyze the efficiency of silo usage and material flow, providing a scientific basis for a company's inventory management and production scheduling. With the continuous advancement of technology and the promotion of its applications, these robots are expected to be applied in a wider range of industrial fields, further advancing industrial automation. The development and application of cement silo cleaning robots have driven the development of related technologies, including robotics, sensor technology, and automated control technology. The progress of these technologies not only enhances the performance of cement silo cleaning robots but also provides technical support for other fields of industrial automation.   The cement silo cleaning robot, with its characteristics of high efficiency, safety, and environmental friendliness, is becoming an important trend in the field of industrial cleaning. With the continuous maturation of technology and the deepening of its applications, we have reason to believe that this type of robot will play an increasingly important role in future industrial production.

In the area of modern industry, the efficiency of material storage and handling is very important. Recently, a groundbreaking patent technology—the multi-chambered silo—has emerged, offering a novel solution that enhances the efficiency of material storage and revolutionizes the field of granular mechanics modeling technology.   The design of this new type of feeding silo is quite distinctive, consisting of a cylindrical outer wall and a bottom bin at the base. Most notably, its internal structure is ingeniously designed into multiple independent test chambers, separated by special partitioning components. These partitioning components feature flat-plate structured inner walls that interlock with the inner surface of the outer wall through slots, ensuring structural stability and flexibility.   Each test chamber is equipped with a corresponding first discharge opening, with valves installed at the discharge opening position to precisely control the flow of materials. Additionally, to monitor the material level information in real-time, each chamber is fitted with a level detection unit, allowing operators to accurately grasp the storage status of materials.   The design of this new storage silo building not only improves the efficiency of material storage but also offers the possibility for precise management and control of materials. By separating materials into different chambers, it is possible to conduct individual tests and treatments based on the characteristics of different materials, which is significant for studying the flow properties of materials and optimizing storage solutions.   Furthermore, the pressure testing device of this silo tank, including pressure sensors installed in the test chambers and a controller for data exchange, provides technical support for real-time monitoring and analysis of pressure changes during material storage. This is crucial for preventing and reducing potential safety issues that may arise during material storage.   With the promotion and application of this new multi-chambered silo, we foresee its profound impact across various sectors. Primarily, in construction and industrial production, it will enhance the efficiency and safety of material storage.

With its application and popularization, we have every reason to believe that it will bring more convenience and possibilities to industrial production and scientific research.

In the ever-evolving urban landscape, the demand for space is continuously on the rise. Adding floors to existing buildings using lightweight steel structures has become a common solution. This construction method not only expands the usable space of existing steel structure buildings but also optimizes functionality without the need to demolish the original building.    Before embarking on the addition of a floor using steel frame structures, the first task is to assess the load-bearing capacity of the existing steel structure building. This step is crucial as it directly affects the feasibility and safety of the additional floor. Professional steel structural engineers calculate whether the existing structure can withstand the load of the new floor. If not, reinforcement of the structure is required before proceeding with the design and construction of the steel framed structures. This step is fundamental in ensuring the safety of subsequent construction and avoiding future structural safety issues.   Once it is confirmed that the existing structure can meet the demands of the additional floor, the next step is to design detailed plans for the lightweight steel structures and begin the fabrication of components. This phase requires precise calculations and design to ensure that the new floor's light steel structures perfectly match the existing structure. After the components are fabricated, they are transported to the construction site, ready for installation.   At the construction site, the first task is to align the site with the drawings to identify the position of the axes and pre-embedded components. This step demands high precision to ensure the accurate installation of the prefabricated steel buildings. Subsequently, protective setups are erected around the site to ensure the safety of construction personnel and the smooth progress of the construction.   The installation of light prefabricated steel structure building is the core phase of the entire floor addition project. This step includes the sequential lifting and installation of columns, beams, purlins, and other components. During the installation, professional equipment and tools are used to ensure that each component is precisely placed in its designated position. The accuracy of this step directly affects the stability and safety of the entire structure.   After the installation of the lightweight steel structures, the next task is paneling, including the installation of roof panels, wall panels, and the processing of the core tube. This step is not only related to the appearance of the building but also affects its functionality and practicality.   Since the construction process may damage the original waterproof layer, waterproofing treatment must be carried out after the paneling is completed. This step is crucial in preventing rainwater leakage and protecting the internal structure of the building from water damage.   The construction of new walls must be carried out in accordance with the existing structure, and then handed over to the decoration team for subsequent decorative work. This step is the ultimate realization of the building's aesthetics and functionality.   Throughout the entire process of adding floors with lightweight steel framed structures, each step requires strict control and precise operation. From the assessment of load-bearing capacity to the final decorative work, every step is vital, not only concerning the safety of the building but also affecting its service life and functionality. With a professional construction team and strict quality control, adding floors with lightweight steel structures can become an effective way to expand urban building space.

The arrival of the rainy season presents a significant challenge for the construction of lightweight steel structures. During this period, it's crucial not only to maintain the pace of construction but also to ensure the quality and safety of the work. This article will introduce key measures to consider when installing lightweight steel structures during the rainy season and how to address the challenges brought by the rain through these measures.   When constructing in the rainy season, we adhere to the overarching principle of "adequate drainage, water blocking, and waterproofing." Our goal is to ensure that indoor projects remain unaffected by the rainy season, while outdoor projects continue in light rain, pause during heavy rain, and resume swiftly after a storm. Although the quality of construction on rainy days may be lower than on sunny days, appropriate measures can minimize this impact.   It's essential to gather meteorological information to prepare thoroughly for construction during the rainy season. Under the leadership of the technical director, technicians are responsible for compiling technical measures for rainy season construction and providing detailed guidance. Besides, steel structure project managers are in charge of coordinating the human, financial, and material resources needed for rainy season construction to ensure smooth progress.   Lightning protection is crucial during rainy season construction. All formwork must be elevated from the ground when stacked to prevent damage from water immersion. Formwork release agents should be covered with plastic sheets after application to prevent the isolation layer from being washed away by rain. For steel structure materials, effective covering is also necessary, ensuring that the storage area has a good drainage system to prevent rusting due to water immersion.   Welding work of prefabricated steel structures should not be conducted in the rain, but it can be protected by constructing processing sheds. Welding machines, wires, and gas cylinders should be stored in dedicated sheds to prevent moisture damage. During welding of prefabricated steel structures, it's important to prevent rain from affecting the quality of the welds. As for high-strength bolt installation, during the rainy season, it's essential to ensure that construction personnel have rain gear and to pay special attention to electrical safety during prefabricated steel structures construction.   Temporary electricity sites need to be protected during rain. The power should be cut off when not in use to prevent electrical accidents. For scaffolding, it's mandatory to inspect the clamps one by one before and after the rain and ensure that the foundation is solid. During inspections, construction and inspection personnel must ensure their safety measures are in place, paying attention to slip prevention and fall protection.   Although the rainy season brings many inconveniences to the construction of portal frame steel structure, by taking the aforementioned measures, we can effectively address the challenges posed by the rain. The key lies in advance preparation, scientific management, and strict implementation of safety measures. In this way, even during the rainy season, we can ensure the quality and safety of portal frame steel structures and complete construction tasks on time. 

In the vast arena of the automotive industry, innovative technologies shine like bright stars, and 3D printing technology is undoubtedly one of the most dazzling. It has not only changed the design and manufacturing processes of cars but also shown revolutionary impacts in terms of performance enhancement and cost reduction.   Toyota's Hyper-F concept vehicle is a prime example of this technological innovation. This SUV model stands out not only in appearance but also in performance.

Through 3D printing, Toyota can manufacture sturdy and large-sized parts at a low cost and high efficiency, such as the engine hood vent panels, which would be unimaginable in traditional manufacturing.   The front bumper of the Toyota Hyper-F concept vehicle uses Tafnex material, a unidirectional polypropylene resin board reinforced with carbon fiber, manufactured by Mitsubishi Chemical. Tafnex's lightweight characteristics not only reduce the vehicle's weight and enhance performance but also offer a unique marble texture due to its moldability, bringing new possibilities to automotive design. The application of this material is not limited to the automotive industry; its widespread use in drone fields also proves its potential across industries.   The impact of 3D printing technology extends far beyond this. Stuttgart University's Rennteam racing team uses Farcast Intelligent's 3D printing technology to customize solutions for electric racing cars, achieving design flexibility and lightweighting. Meanwhile, MD ELEKTRONIK quickly manufactures injection molding molds using the Nexa3D printer and Ultracur3D® RG 3280 resin material, significantly shortening the time from product design to market and reducing costs.   With the development of 3D printing technology, metal fabrication is playing an increasingly important role in the new era of automotive manufacturing. Metal 3D printing, also known as metal additive manufacturing, allows manufacturers to create complex metal parts directly from digital models. This technology not only improves manufacturing precision and efficiency but also makes design more flexible, enabling the production of complex structures that traditional fabricated metal techniques find difficult to achieve.   The application of metal 3D printing technology allows automotive manufacturers to respond more quickly to market changes, achieve personalized customization, and be more economical in material use. The development of this technology indicates that the automotive industry will focus more on sustainability and environmental friendliness, while also bringing new improvements to the performance and safety of cars.   The application of 3D printing technology in the automotive industry is not just a revolution in the manufacturing process but also a profound impact on the future development of the entire industry. From design to manufacturing, from materials to performance, 3D printing technology is reshaping every aspect of the automotive industry. With continuous technological advancements, we have reason to believe that 3D printing technology will continue to lead the automotive industry towards a more efficient, environmentally friendly, and innovative future.

In August 2024, a groundbreaking achievement on the International Space Station (ISS) revolutionized the field of metal manufacturing—successfully utilizing 3D printing technology to fabricated sheet metal parts in space for the first time. This feat not only marks a significant leap in space manufacturing but also paves new paths for future space exploration and orbital production and maintenance missions.   Led by the European Space Agency (ESA), this pioneering mission has proven the feasibility of printing metal parts in a microgravity environment. The metal 3D printer, developed by Airbus and its partners with funding from ESA, arrived at the ISS in January 2024, with its core objective being to explore the possibility of printing metal parts in such a unique environment.   Traditional space exploration missions require all parts to be produced on Earth and transported to orbit, a process that is costly and logistically complex. The application of metal 3D printing technology enables astronauts to potentially manufacture tools, parts, and even replacement parts directly in orbit, saving time, reducing costs, and enhancing the self-sufficiency of space missions, especially for long-term missions.   Due to the effects of microgravity, space manufacturing is much more complex than manufacturing on Earth. Traditional manufacturing methods rely on gravity to position materials and guide the process flow, and in a microgravity environment, the behavior of processes like molten metal deposition is unpredictable. Engineers had to develop new strategies and technologies to adapt the 3D printing process to these challenging conditions. The ISS provided a unique testing platform for these challenges and the development of viable solutions.   After the printer arrived at the ISS, astronaut Andreas Mogensen played a key role in installing the machine. Safety was the top priority for the project, with the printer being sealed to prevent any harmful gases or particles from escaping into the ISS atmosphere. This process also included careful control of the printer's internal environment to minimize risks during operation.   The actual process of 3D printing began with the deposition of stainless steel. Unlike traditional desktop 3D printers that use plastic filaments, this printer uses stainless steel wire melted by a high-power laser, which heats the metal wire to over 1200°C and deposits it layer by layer onto a moving platform.   By mid-July 2024, the team had successfully printed 55 layers, marking the completion of half of the first sample. This achievement heralds the start of the so-called "cruise phase," where the team was able to accelerate the printing process. These optimizations have made the printer's operation more efficient, increasing the daily printing time from 3.5 hours to 4.5 hours.   The successful application of metal 3D printing technology not only provides greater flexibility and self-sufficiency for space missions but also has a profound impact on the field of metalworking and manufacturing. This technology can be used to manufacture everything from spare parts to large structures in space, supporting long-term exploration and colonization of other planets. As technology continues to advance and improve, we can look forward to more innovations and breakthroughs in the field of space manufacturing through metal 3D printing.
