The rolling process of precision stainless steel foil with a width of 500mm or more and a thickness of 0.02mm and the stainless steel foil produced thereby

Abstract

The invention relates to a rolling process of a precise stainless steel foil with the width of more than 500 mm and the thickness of 0. 02mm. The rolling process comprises the following steps of 1, selecting materials, wherein the thickness is selected to be 0. 35mm, and the BWG304L stainless steel coil with the width ranging from 550 mm to 650 mm is used as a rolling raw material; 2, an intermediate rolling pass rolling, the intermediate rolling pass is subjected to three-pass rolling, and rolling to 0. 035mm from 0. 35mm; 3, a finished product rolling pass rolling, wherein the diameter of the finished product rolling pass rolling working roll is 20mm to 30 mm, the material is selected as M2, the roughness Ra is 0. 1 mu m to 0. 25mu m, the finished product rolling pass is subjected to four-pass rolling, and is rolled to 0. 02mm from 0. 035mm, the rolling tension of the finished product is controlled to be 250 N / mm2 to 450 N / mm2, and the rolling force is controlled below 500 KN. The surface quality and the actual plate shape of the 0. 02 mm precision stainless steel foil produced by the rolling technology are good, is suitable for industrial mass production, and meets the high-quality requirement of the high-end industry of the precision stainless steel foil.

Description

technical field [0001] The present invention generally relates to the technical field of steel rolling. More specifically, the present invention relates to the field of stainless steel rolling, especially the rolling process of ultra-thin precision stainless steel strip, especially the rolling process of precision stainless steel foil with a width of 500 mm or more and a thickness of 0.02 mm. Background technique [0002] Ultra-thin precision stainless steel strips have entered the fields of aerospace, petrochemical, medical electronics, communication semiconductors, auto parts, computer products, etc., and have very high added value, which is also important for the metal properties, corrosion resistance, and surface quality of stainless steel. put forward higher requirements. Especially for precision stainless steel foil products with a width of 500mm or more and a thickness of 0.02mm, in the relevant existing technologies, there is no domestic technology for producing 0.0...

AI Technical Summary

Problems solved by technology

Especially for precision stainless steel foil products with a width of 500mm or more and a thickness of 0.02mm, in the relevant existing technologies, there is no domestic technology for producing 0.02mm precision stainless steel foil products, and only a few companies in Japan and the United States can produce 0.02mm Stainless steel foil products, but its width is limited, and the actual width can be produced below 450mm

Therefore, on the one hand, there is a great demand in the market, but on the other hand, there is currently a lack of rolling process for precision stainless steel foil with a width of more than 500mm and a thickness of 0.02mm.
