Cold rolling system of stainless steel strip

Abstract

The invention discloses a cold rolling system of a stainless steel strip. The cold rolling system comprises a feeding device, an inlet loop connected with the feeding device, a laser welding machine connected with the inlet loop, a first cold rolling machine connected with the laser welding machine , a second cold rolling machine connected with the first cold rolling machine, a third cold rollingmachine connected with the second cold rolling machine, a fourth cold rolling machine connected with the third cold rolling machine, a fifth cold rolling machine connected with the fourth cold rollingmachine, a sixth cold rolling machine connected with the fifth cold rolling machine, a cleaning machine connected with the sixth cold rolling machine and an outlet loop connected with the cleaning machine. The system has the advantages that the structure is reasonable, space is saved, continuous production can be realized, the mechanical property of finished products after rolled is good, the thickness range is wide, the thickness can reach 0.2mm-4 mm, the roughness is small, and the appearance is bright and high-class.

Description

technical field [0001] The invention relates to the technical field of stainless steel, in particular to a cold rolling system for stainless steel strips. Background technique [0002] Stainless steel strip is an extension of ultra-thin stainless steel plate. It is mainly a narrow and long steel plate produced to meet the needs of industrial production of various metal or mechanical products in different industrial sectors. It is widely used in high-tech industries, IT industries, and Aviation and aerospace industries have high added value, but the rolling process is difficult to master, because internal stress will be generated inside the stainless steel strip after the initial rolling, which affects the effect of finishing rolling and has a great impact on the forming of the finished product. The finished products have different requirements on hardness, which increases the difficulty of the rolling process, the production efficiency is low, and the finished product rate i...

[0002] Stainless steel strip is an extension of ultra-thin stainless steel plate. It is mainly a narrow and long steel plate produced to meet the needs of industrial production of various metal or mechanical products in different industrial sectors. It is widely used in high-tech industries, IT industries, and Aviation and aerospace industries have high added value, but the rolling process is difficult to master, because internal stress will be generated inside the stainless steel strip after the initial rolling, which affects the effect of finishing rolling and has a great impact on the forming of the finished product. The finished products have different requirements on hardness, which increases the difficulty of rolling process, low production efficiency and low yield

[0003] Moreover, the thickness range of the stainless steel strip produced by the prior art is relatively narrow, usually 0.5-2.0mm, which cannot meet the requirements of different processing fields for stainless steel strips of different thicknesses.

In addition, the stainless steel strip produced by the prior art has a relatively large roughness, resulting in dull surface and low grade

And the larger roughness will also affect the surface quality of the stainless steel strip
