A kind of production method of ultra-thin steel strip

Abstract

The invention belongs to the technical field of strip steel production, and in particular relates to a production method of extremely thin strip steel. The production method includes: processing a strip steel that meets the thickness requirements, and the ends of the head and tail of the strip steel that meet the thickness requirements have thickened parts; push the strip steel that meets the thickness requirements to a welding machine, and pass the welding machine to meet the thickness requirements. The head of the required strip is welded with the tail of the previous roll of strip that meets the thickness requirements. The invention enables the unit to continuously produce finished products of required thickness, that is, without changing the existing equipment, the finished products can be smoothly rolled off the production line, the use requirements of high-end customers are met, the time cost is reduced, and the market competitiveness is increased.

Description

technical field [0001] The invention belongs to the technical field of strip steel production, and in particular relates to a production method of an ultra-thin strip steel. Background technique [0002] Cold-rolled non-oriented silicon steel is an important raw material product in my country's household appliances, small and medium-sized motors, large-scale motors, electronic products and other industries. With the rise of the new energy vehicle and drone markets, customers' requirements for product thickness gradually tend to be thinner. Development, from 0.35mm to 0.3mm, gradually reduced to 0.25mm, and finally to the limit specification of 0.2mm. [0003] The product production limit in the equipment process in the prior art is 0.3mm thickness products, for products below 0.25mm, especially 0.2mm products, there is no operating condition at all, and it is impossible to mention that finished products can be produced. If there is a major transformation of the unit or a new...

[0003] The production limit of products in the equipment process in the prior art is 0.3mm thickness products, for products below 0.25mm, especially 0.2mm products, there is no operating condition at all, and it is impossible to mention that finished products can be produced

If there is a major transformation of the unit or a new production line, the time cost is huge, and it is impossible to quickly provide customers with trial products in the short term, which will miss the huge market of new energy and drones, reduce the influence of non-oriented products, and even drag down the entire industry.
