AI Technical Summary
In the existing flattening equipment, the pressure varies with the roll diameter during the strip rolling process, which affects the strip quality and yield, especially for ultra-thin strips. In addition, the equipment is complex and costly.
A constant pressure mechanism is adopted, which uses a combination of a balance cylinder, a pressure roller bracket, a balance support and a balance coil spring to achieve constant pressure on the flattening roller and the lower pressure roller. The pressure of the flattening roller on the strip surface is kept constant by the follow-up movement of the balance cylinder and the tension adjustment of the coil spring.
It achieves stable and efficient flattening of strip, improves yield and surface quality, reduces equipment complexity and cost, and enhances production efficiency.
