Process for producing accurate stainless steel band applied in electronic industry

Abstract

The invention relates to a process for producing an accurate stainless steel band applied in an electronic industry. The process comprises the following steps of: the first cold rolling process; the first spray degreasing process; the first hot-water spraying process; the first hot-wind drying and solid dissolving process; the second cold rolling process; the second spray degreasing process; the second hot-water spraying process; and the second hot-wind drying process, bending stretching and straightening process and the process of cutting into finished products. According to the production process, a twenty-Hi sendzimir rolling mill and an unique rolling process are adopted for cold rolling; and the processes such as degreasing, solid dissolving treatment, bending stretching, straightening, and the like are performed, so that the product has little tolerance fluctuation of the thickness, stable performance, uniform surface color and roughness and no color difference, good plate flatness, improved quality and capacity of meeting the requirements of the electronic industry on top quality.

Description

technical field [0001] The invention relates to a production process of a precision stainless steel strip widely used in processing accessories of mobile phones, computers and electronic products. Background technique [0002] At present, the precision stainless steel strips used in the electronics industry are rolled by multi-roll mills, and other auxiliary equipment are used to improve the surface and flatness of the plate. However, the stainless steel strips made by the existing technology have large fluctuations in thickness tolerance. , Unstable mechanical properties, uneven surface color and roughness, poor flatness of the plate shape and other shortcomings. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a production process for precision stainless steel strips that can produce stable performance, small fluctuations in thickness tolerance, uniform surface color and roughness without...
