1. Strictly control the chemical composition of steel according to the standard of cold heading steel, optimize the organization of the material, increase the plasticity of the material, ensure the stability of the steel performance, reduce the hazards of inclusions on performance, and reduce the content of harmful elements in the steel.
Second, through the control of the smelting and rolling process, reducing the amount of rolling, rolling pass and number of times of turning steel, in order to obtain uniform and refined grain structure, avoid wrinkles in the production process and folds generated by the ears. Improve the comprehensive mechanical properties of cold heading steel.
Third, choose the appropriate roll and uniform hole type system to ensure that the product surface smooth, while reducing the finished crack, improve the quality of production spare parts, and ensure process requirements.
Fourth, strictly control the heating temperature, time and furnace atmosphere, maintain positive pressure operation, reduce surface burnout and surface decarburization.
