▎ 摘　　要

NOVELTY - Preparing steel ball for wear-resistant corrosion-resistant ball mill comprises (1) heating and smelting raw material of steel ball base in electric furnace to obtain molten steel, casting molten steel to obtain casting blank, heating casting blank, rolling into ball, and cooling steel ball base body, (2) uniformly mixing aluminum-nickel alloy powder, graphene oxide coated silicon carbide whisker to obtain middle bonding layer powder, spraying middle bonding layer powder on surface of te steel ball base by plasma spraying to obtain first coating steel ball, (3) uniformly mixing chromium oxide powder, silicon dioxide powder to obtain surface coating layer powder, using plasma spraying the surface coating layer powder sprayed on the first coating steel ball surface, forming surface coating layer, and obtaining secondary coating steel ball, and (4) secondary coating steel ball for hot isostatic pressing treatment, cooling to room temperature, tempering at low temperature, and cooling. USE - The method is useful for preparing steel ball for wear-resistant corrosion-resistant ball mill. ADVANTAGE - The ball has excellent wear resistance, corrosion resistance, low corrosion loss and long service life. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for wear-resistant and corrosion-resistant steel ball for ball mill prepared by the above preparation method.
