Does the black ash pressing of aluminum coils have an effect on cold rolling?

1. Optimize the surface treatment of the roller: surface treatment of the roller, such as coating or spraying, can improve its wear resistance and fatigue resistance, thus reducing the black ash indentation.

2, regular inspection and maintenance of equipment: regular inspection and maintenance of cold rolling equipment to ensure its normal operation. For the problems found, repair and replace them in time to reduce the risk of black ash pressing in.
