Problems solved by technology

The traditional process is bell-type stress relief annealing process, the hardness of the product is not uniform, the yield strength and elasticity are not uniform; the traditional process only has one tension leveling process, and its plate shape is relatively poor, and the plate shape is warped; the traditional process is not cold-rolled after cold rolling. Cleaning, so that the surface quality of the product is relatively poor; the traditional process uses fourteen rolls to produce three-process rolling, which reduces production efficiency and low yield

Abstract

The invention relates to a production method of a stainless steel belt for an electronic film. The production method comprises the following steps: (1) selecting and using a 12Cr17Ni7 stainless steel belt billet with the thickness of 0.7-1.0 mm; (2) rolling the stainless steel belt into a steel belt with the thickness of 0.16-0.18 mm by a 20-roll precision cold rolling machine set; (3) washing the steel belt for one time; (4) passing a continuous hydrogen-spraying bright annealing furnace by the steel belt; (5) rolling the steel belt into a steel belt with the thickness of 0.03-0.05 mm by the 20-roll precision cold rolling machine set; (6) passing a continuous degreasing washing machine set by the steel belt; (7) straightening the steel belt by a 23-roll precision stretch bending straightening machine; (8) passing the continuous hydrogen-spraying bright annealing furnace by a rusted steel belt; (9) straightening the steel belt in the direction opposite to the warping direction by the 23-roll precision stretch bending straightening machine; (10) cutting the steel belt into a steel belt with the required size so as to obtain the stainless steel belt for the electronic film. The stainless steel belt produced by the method is good in elasticity, high in strength and uniform in thickness.

Description

technical field [0001] The invention relates to a production method of a stainless steel strip, in particular to a production method of a stainless steel strip for an electronic thin film. Background technique [0002] With the continuous advancement of science and technology and the increasingly popular use of mass electronic products, people's requirements for products are also getting higher and higher. Electronic membrane switches are mainly used in mobile phones, PHS, electronic dictionaries, calculators, walkie-talkies, cordless phones, toys, household appliances, industrial control panels, medical equipment, etc., and are widely used in civilian electronic products and industrial (including military) products. Widely used, such as elastic buttons for various high-precision and high-demand electronic products.
