The thickness accuracy and flatness of 1mm aluminum sheet are two important indicators that reflect the quality of aluminum foil products. Aluminum foil longitudinal thickness accuracy detection components, closed-loop shape control system by means of various parameter control. There are many ways to control and adjust the plate shape, which can be roughly divided into three categories:

One is to start control from the raw materials, that is, control the original convexity of the raw materials to meet certain requirements.

The second is to adjust the rolling process, such as oil painting rolling schedule, changing the front and back tension, speed, applying bending force, rolling roller cooling section control, etc.

The third is equipment adjustment. Various new rolling mills can effectively control the strip shape.
