Hot Rolling U-shape Steel for Mine Tunnel Support
U-shaped steel is an important material used in mine tunnel support. It provides structural support and stability so that the tunnel is secure, and miners can safely access the staircase leading to the mine safely. Hot rolling U-shape steel for mine tunnel support (GB/T4697-1991) is made from steel plate with a thickness of 6mm-20mm and a width of 100-500mm. Because of this, the steel’s ribbing and section size of the hot rolled U-shape steel can be adjusted accordingly to meet customer needs. U-shape steel has excellent performance at resistance of twisting and bearing pressure, which helps improve its security.
The technologies used to produce hot rolling U-shape steel for mine tunnel support must meet the requirements of GB/T4697-1991. This includes production processes such as forming, degreasing, cleaning, galvanizing, leveling, cooling, trimming and so on. These processes must be precisely controlled in order to produce the desired product. For example, the forming process must be accurate so the steel will maintain its required shape and size. The galvanizing process must also be carefully monitored to ensure that the steel is adequately corrosion-protected. Moreover, the temperature control must be monitored closely so that the steel maintains desired mechanical properties and does not distort.
Additionally, the quality control for the U-shape steel for mine tunnel support must also be strictly implemented. At each stage, inspections and tests must be conducted to make sure the product meets requirements. Inspection and testing of the hot rolling U-shape steel for mine tunnel support should include a visual inspection, a physical property test, a thermal property test and a magnetic property test. This ensures that the steel has the required mechanical properties, ductility and toughness, and will not be prone to deforming when used in mining applications.
In the end, hot rolling U-shape steel for mine tunnel support (GB/T4697-1991) has been widely used in mine tunnel support. The steel has excellent performance in resistance of twisting and bearing pressure and has been highly praised by customers, making it one of the best products to use in mine tunnel support applications. It is also important to remember to carefully control the production process and product quality to make sure the steel meets customer requirements and to ensure product reliability and safety.
