Publish Time: 2024-06-13
The manufacturing technology and quality control of Alloy Structural Steel are the key links to ensure its high performance and wide application. The following is a detailed analysis of these two aspects:1. Manufacturing technologyThe manufacturing technology of Alloy Structural Steel mainly includes smelting, rolling and heat treatment.Smelting: During the smelting process, the uniform distribution and appropriate content of alloy elements are ensured by controlling the ratio of raw materials and smelting temperature. The smelted steel billet must undergo strict chemical composition analysis and physical property testing to ensure that it meets the predetermined standards.Rolling: Rolling is the process of processing steel billets into steel plates or steel bars of specified size and shape. By adjusting the rolling process parameters, such as rolling temperature, reduction and rolling speed, the internal structure and properties of steel can be controlled.Heat treatment: Heat treatment is an important link in the manufacturing process of Alloy Structural Steel. Through quenching, tempering and other processes, the microstructure and properties of steel are improved. The heat-treated steel has high tensile strength, yield strength ratio and toughness, which can meet the needs of various engineering components and mechanical parts.2. Quality ControlQuality control runs through the entire process of Alloy Structural Steel manufacturing, including quality control of raw materials, quality control in the production process and quality control of finished products.Quality control of raw materials: mainly to strictly inspect the composition, organization and surface quality of raw materials to ensure that the raw materials meet production requirements.Quality control in the production process: mainly to strictly control each process link to ensure stable product quality. This includes monitoring and adjustment of process parameters such as smelting, rolling and heat treatment, as well as maintenance and overhaul of production equipment.Quality control of finished products: mainly to comprehensively test the size, appearance quality, mechanical properties and welding properties of steel to ensure that the product meets standard requirements. This includes tensile, impact, bending and other performance tests on steel, as well as surface quality and internal defects of steel.
