Continuous casting and rolling is a kind of steel rolling process which consists of the continuous casting and rolling process. It has the following characteristics:
1. continuous casting and rolling can reduce the quality of ingot, reduce labor intensity, increase productivity and reduce production costs.
2. Continuous casting and rolling can be applied to various structural steel and alloy steel.
3. The structure of the cast and rolled steel is finer and more uniform, and has excellent cutting performance.
4. Continuous casting and rolling can improve the surface quality of the steel rolls and eliminate the scale on the surface.
5. Continuous casting and rolling can reduce the internal stress of the steel strips and make them more uniform.
6. Compared with other processes, continuous casting and rolling can reduce the production cycle, improve the producing speed, reduce the metal loss and reduce the emergence rate of the defects.
7. Compared with other processes, continuous casting and rolling can achieve efficient process integration and reduce energy consumption.
8. The equipment is simple and the operation is reliable.
Deep universal rolling with thin plate steel is a new technology developed in recent years, which is a kind of continuous hot rolling steel forming technology. Deep universal rolling with thin plate steel has the following characteristics:
1. At present, most of the equipment of deep universal rolling with thin plate steel has higher accuracy and works more stable, which can meet the forming requirements of various parts.
2. Deep universal rolling with thin plate steel can carry out the rolling processing of steel plates with different thickness and length at the same time.
3. The rolling loss is small, and the deformations of the two sides of the rolled pieces are required to be consistent.
4. The deep universal rolling of thin plate steel can reduce the internal stress generated during the rolling process and increase the accuracy of modeling. The space-time relationship between the two sides of the rolled steel is more stable.
5. The edge quality of deep universal rolling of thin plates is also higher, which is beneficial to automatic welding, painting, welding and other working processes.
Besides, deep universal rolling of thin plate steel also has some disadvantages: the cost of deep universal rolling of thin plate steel is high, the minimum rolling thickness is still relatively large, and it is inevitable that losses will occur when rolling thin plates.
