Embodiment 1

[0018] The high-speed steel roll made of W6Mo5Cr4V2 is used for grinding, and the green silicon carbide resin grinding wheel with a particle size of 240 is used. The speed of the grinding wheel is 15m / s, and the speed of the roll is 120r / min. Good rolls are subjected to sandblasting and texturing, the sandblasting granularity is 46, the compressed air pressure is 0.40MPa, the spray gun moving speed is 0.10m / min, the roll speed is 90r / min, and the sandblasting time is 10min per roll. The ten-roller finished product rolling pass adopts textured rolls to roll 3000 meters of stainless steel strip with a specification of 0.20×400mm, and the surface roughness of the steel strip after rolling is Ra0.80~1.0μm.

Abstract

The invention relates to a production method of precision stainless steel band with roughened surface, which comprises the following steps: (1) grinding with roller, wherein, the material of the roller is W6Mo5Cr4V; (2) sandblasting and roughening with roller; (3) rolling with twenty rollers. The production method is characterized in that the roller enables to roll continuously over 3000 meters to produce obvious change in roughness; the roughness of the roughened surface of roller is controlled through changing the granularity of the blasting sand. The production method adopts the sand with 46 to 100 granularity, wherein, the higher the granularity of the blasting sand, the lower the surface roughness of the roughened roller, and the surface roughness of the rolled steel band is also lower. The production method has the advantages of simple method, low cost and controlling range of 0.50 to 1.0 Mum for the surface roughness of the precision stainless steel band with roughened surface.

Description

technical field [0001] The invention belongs to the field of production methods of stainless steel strips, in particular to a production method of precision stainless steel strips with textured surfaces. Background technique [0002] The use of stainless steel strip products is different, and customers have different requirements for the surface of the steel strip. When stainless steel strip products go through processes such as electroplating and coating, the surface of the product is usually required to be rougher, with a roughness of Ra 0.50-1.2μm. The textured surface precision stainless steel strip is for A special surface stainless steel strip produced to meet customers' electroplating and coating. The national standard stipulates that there is a stainless steel strip with a 2D surface, which is produced by cold-rolled stainless steel strips after annealing and then mildly cold-leveled with rough-faced rolls. It is not suitable for the production of semi-hard and hard...
