Working Principle Of Cold Rolling Mill

Pickling and annealing in the working principle of cold rolling mills In commonly used cold rolling mills, many people do not understand the principles of pickling and annealing of cold rolling mill technology. This document mainly introduces the acid in cold rolling mills. The principle of the washing and annealing process, because there is a layer of iron scale on the surface of the strip before cold rolling, the iron scale must be cleaned this time. This is the first step of cold rolling technology---pickling, which is then rolled. The rolled strip steel needs to be annealed due to work hardening. After the strip steel is softened, the grease on the surface needs to be cleaned. If the cleaning is not clean, the finished strip steel will have plaques on it. After the grease treatment The surface of the strip steel after annealing is bright. In order to obtain the required size and thickness, the finished strip steel product that meets the requirements is obtained after being processed by a leveler.
