Due to no heating, there are no pitting and scale defects in hot rolling. The surface quality is good and the surface finish is high. Moreover, the dimension precision of cold rolled products is high, and the properties and structure of products can meet some special requirements, such as electromagnetic properties, deep drawing properties, etc.
