Today we will talk about the technical points of rolling hard coil products!

In fact, hot-rolled steel coils are used as raw materials, and after acid washing to remove oxide scales, cold continuous rolling is carried out. The finished product is rolled hard coils. Due to the cold work hardening caused by continuous cold deformation, the strength and hardness of the rolled hard coils increase, and the toughness and plasticity index decrease. Therefore, the stamping performance will deteriorate, and can only be used for parts with simple deformation.

Principles of safety production

Safety production must follow the following principles: 1. The principle of combining prior education with prior prevention Enterprise safety production is not only related to the property interests of the enterprise, but also directly affects the life safety of its employees.
