Ferritic stainless steel cold-rolled strip steel production device

Abstract

The invention belongs to the technical field of strip steel production and processing, and particularly relates to a ferritic stainless steel cold-rolled strip steel production device, which comprises an uncoiler, a straightening machine, a pickling machine, a rolling mill and a coiler, and the pickling machine comprises a pickling tank, an inner tank, first grinding rollers, second grinding rollers and a motor; the pickling tank is fixedly connected to the ground; the inner tank is arranged in the pickling tank and slides on the inner wall of the pickling tank; first grinding rollers and second grinding rollers are arranged in the inner tank, the first grinding rollers and the second grinding rollers are rotationally connected with the inner tank, the number of the first grinding rollers is two, and the number of the second grinding rollers is two; the first grinding rollers and the second grinding rollers are vertically arranged in the inner tank; the motor is fixedly connected to the outer side of the inner tank; a pickling solution in the tank is used for pickling the polished strip steel, and the two modes of polishing and pickling are combined, so that the pickling quality and efficiency are improved, the strip steel is protected, the strip steel is prevented from being damaged due to excessive polishing, and the production and processing quality of the strip steel is improved.

Description

technical field [0001] The invention belongs to the technical field of strip steel production and processing, in particular to a production device for ferritic stainless steel cold-rolled strip steel. Background technique [0002] Steel is one of the most common metal products in our life. Strip steel is the most common steel product. Strip steel is produced by various steel rolling enterprises to meet the needs of industrial production of various metal or mechanical products in different industrial sectors. Narrow and long steel plate. Strip steel, also known as steel strip, is within 1300mm in width, and the length is slightly different according to the size of each roll. The production process of cold-rolled strip steel is generally: blank—pickling—rolling—annealing—synchronous lubrication of rolling size—antirust oil—leveling and sizing—polishing—packaging. There are cracks and pores on the surface of the steel strip, and the pickling liquid reaches the metal surface a...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: in the pickling process, the iron oxide scale on the strip head (pickling strip tail) and the middle surface is the most difficult to wash off, and the existing pickling equipment cannot remove the dense iron oxide scale. Thus affecting the overall cold rolling quality of the strip
