Embodiment 1

[0016] The 430 hot-rolled stainless steel plate with a thickness of 3mm is selected as the raw material, and it is sent to a reversible twenty-high rolling mill for rolling. First, the work roll with a roughness of about 0.5μm is used for rolling. , for the last rolling pass. The last pass of rolling is carried out with work rolls with a roughness of 3.0 μm, the reduction rate is controlled at about 8%, and the rolling speed is controlled at about 100m / min. After the rolling is completed, a cold-rolled steel plate is obtained. After testing, the average roughness of the cold-rolled steel plate is 1.7 μm.

Embodiment 2

[0018] The 430 hot-rolled stainless steel plate with a thickness of 3mm is selected as the raw material, and it is sent to a reversible twenty-high rolling mill for rolling. First, the work roll with a roughness of about 0.5μm is used for rolling. , for the last rolling pass. In the last pass, work rolls with a roughness of 4.0 μm are used for rolling, the reduction ratio is controlled at about 8%, and the rolling speed is controlled at 100m / min. After the rolling is completed, a cold-rolled steel plate is obtained. After testing, the average roughness of the cold-rolled steel plate is 1.9 μm.

Embodiment 3

[0020] The 430 hot-rolled stainless steel plate with a thickness of 3mm is selected as the raw material, and it is sent to a reversible twenty-high rolling mill for rolling. First, the work roll with a roughness of about 1.0μm is used for rolling. , for the last rolling pass. In the last pass, work rolls with a roughness of 3.7 μm are used for rolling, the reduction rate is controlled at about 8%, and the rolling speed is controlled at 100m / min. After the rolling is completed, a cold-rolled steel plate is obtained. After testing, the average roughness of the cold-rolled steel plate is 1.8 μm.

[0021] The work roll of embodiment 1-3 is obtained through the following steps: (1) process the surface of work roll with grinding wheel, to remove the defect of work roll surface; (2) process work roll surface with laser roughening equipment, by adjusting The output power of the laser texturing equipment is used to obtain work rolls with different surface roughness; among them, the la...

Abstract

The invention discloses a stainless steel plate and a manufacturing method thereof. The stainless steel plate is manufactured through the following steps that the stainless steel plate is subjected tocold rolling through a twenty-high rolling mill, the last pass of cold rolling is conducted through working rollers with the roughness average Ra being 3.0-3.4 [mu]m, and the steel plate with the roughness average Ra being 1.7-1.9 [mu]m is obtained after rolling. The surface of the stainless steel plate prepared through the manufacturing method is a matte surface uniform in brightness, and therefore good attractiveness is achieved.

Description

technical field [0001] The present invention relates to a stainless steel plate and its manufacturing method. Background technique [0002] With the advancement of science and technology, people put forward higher requirements for the surface quality of stainless steel. The microscopic topography of the steel plate surface is prepared by the principle of rolling transfer, that is, during the rolling process, the microscopic topography of the roll surface is transferred to the strip steel through rolling plastic deformation. The microscopic appearance of the steel plate surface depends on the surface microscopic appearance of the work roll as the transfer mold, the rolling transfer process and the original surface microscopic appearance of the steel plate. [0003] For a long time, the research on the surface quality of steel plates has mainly focused on the two types of defects, foreign matter adhesion and damage. However, with the improvement of the aesthetic requirements...
