Cold Rolling Mill Technology Sharing
1) Increase roll roughness appropriately. Usually the roughness of finished pass roller is 0.45-0.55μm and the roughness of strip steel is about 0.35μm. In the rolling process, the roughness of the roll will be gradually reduced. Therefore, in the first roll change of the reversible mill, the roughness of the roll will decrease after the ...
