Abstract

The present invention discloses a steel shot composition for middle-high carbon steel, and a preparation method thereof, and belongs to the field of abrasive materials. The steel shot composition comprises, by weight, 5-8% of quartz sand, 20-25% of steel shot, 60-65% of white corundum, and 10-15% of alumina. The invention further discloses the preparation method of the steel shot composition. According to the present invention, the steel shot composition has characteristics of high impact resistance, high abrasion resistance, long service life, effective work-piece surface roughness increasing and meeting of production requirements, wherein the surface roughness Ra achieves 1.6-2.4 [mu]m after the middle-high carbon steel work-piece is subjected to a shot blasting texturing treatment; and the environmental pollution can be effectively reduced, and the steel shot is not easily broken so as to substantially reduce dust pollution during the impeller blasting and shot blasting process, ensure the surface quality of the blasted work-piece, and reduce the environmental pollution.

Description

technical field [0001] The invention relates to the field of abrasives, in particular to a steel shot composition for medium-high carbon steel. Background technique [0002] As we all know, the surface roughness of the roll directly affects the stamping formability of the strip, and the surface roughness of the cold-rolled strip is completely formed by the surface roughness and peak number of the roll after roughening. Therefore, the roughness of the roll surface The quality of processing technology and quality directly affects the use of cold-rolled plates. [0003] Currently commonly used roll texturing technologies are: shot peening (SBT), laser texturing (LT), electron beam texturing (EBT), and electric spark texturing (EDT). Shot peening is the use of a high-speed rotating centrifugal wheel to accelerate the impact material (usually steel shot) with sharp edges and high hardness to the roll to be texturized. When the impact particles hit the surface of the roll, the su...
