Cold Rolling Technology Introduction
Cold rolling refers to cold-drawing, cold-bending, cold-drawing and other cold processing of steel plates or steel strips into various types of steel at normal temperature. It has the advantages of fast molding speed, high output, and does not damage the coating, and can be made into a variety of cross-section methods to meet the requirements of operating conditions. Cold rolling can cause large plastic deformation of the steel, thereby improving the yield point of the steel. Cold-rolled formed steel allows partial buckling of the cross section, which enables full application of the bearing capacity of the member after buckling.
