Production Process Of Cold Rolled Sheet
1. Since no heating is carried out during the production process, there are no defects such as pitting and iron oxide which often occur in hot rolling, and the surface quality is good and the finish is high. Moreover, the dimensional accuracy of the cold rolled product is high, and the performance and organization of the product can meet some special use requirements, such as electromagnetic performance and deep drawing performance.
2. Specifications: The minimum thickness is 0.2-4mm, the width is 600-2 000mm, and the length of the steel plate is 1 200-6 000mm.
3. Grade: Q195A-Q235A, Q195AF-Q235AF, Q295A(B)-Q345 A(B); SPCC, SPCD, SPCE, ST12-15; DC01-06
4. Performance: It mainly uses low carbon steel grades, which requires good cold bending and welding performance, as well as certain punching performance.
