Abstract

The invention discloses a stainless steel cold rolling plate machining method. The method comprises the steps of firstly, raw material treatment, secondly, rolling, thirdly, annealing and acid pickling, fourthly grinding and forming and fifthly electrolytic passivation. A stainless steel cold rolling plate manufactured through the machining method is flat in plate face and uniform in color, the surface appearance quality is greatly improved, through the rolling method, the friction coefficient of the cold rolling deformation area contact surface of the stainless steel plate can be reduced, and therefore the cold rolling pressure is reduced, cold rolling production efficiency is improved, and a rolled part easily extends.

Description

technical field [0001] The invention relates to the field of stainless steel processing, in particular to a processing method for stainless steel cold-rolled plates. Background technique [0002] Since the production process of stainless steel cold-rolled sheets is not heated, there are no defects such as pits and scales that often occur in hot rolling, and the surface quality is good and the finish is high. Moreover, the dimensional accuracy of cold-rolled products is high, and the performance and structure of the products can meet some special requirements for use, such as electromagnetic properties and deep drawing properties. [0003] Cold-rolled strips are widely used, such as automobile manufacturing, electrical products, rolling stock, aviation, precision instruments, food cans, etc. [0004] China is currently the largest consumer and producer of stainless steel in the world. According to statistics from the China Stainless Steel Market Network of the Economic and T...
