Abstract

The invention discloses a machining method for a high-strength and high-abrasion-resistance stainless steel cold-rolled sheet. The machining method comprises the first step of raw material treatment, the second step of rolling, the third step of annealing and acid pickling, the fourth step of polishing and grinding and the fifth step of electrolysis passivation. The stainless steel cold-rolled sheet manufactured through the machining method is high in mechanical strength, good in abrasion resistance, strong acid and strong alkalinity resistance, high-temperature stability and machining performance, and the like. The sheet face is flat, colors are uniform, the surface appearance quality is greatly improved, more uniformity is achieved through electrolysis passivation, the density of a passivation layer is high, and the anti-corrosion capability of the stainless steel cold-rolled sheet can be greatly improved; and the surface can prevent oil dirt, and the dirt preventing and fingerprint pressing preventing capability of the surface of the stainless steel cold-rolled sheet is improved.

Description

technical field [0001] The invention relates to the field of stainless steel processing, in particular to a processing method for a high-strength and high-wear-resistant stainless steel cold-rolled plate. 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 Ste...
