Description

technical field [0001] The invention relates to the technical field of iron and steel product production, in particular to a wire rod for high-carbon steel wire cutting shots and a production method thereof. Background technique [0002] Shot peening of metal surface is a method of using mechanical centrifugal or pneumatic equipment to inject abrasives at high speed, impacting the surface of transmission parts to cause surface deformation and produce compressive stress, plastic deformation, and surface deformation strengthening method, which can improve And improve the surface properties of parts and fatigue strength, among which high carbon steel wire cutting shot is an ideal metal abrasive for shot blasting. [0003] At present, shot peening cleaning and strengthening are more and more widely used in industrial production. The annual consumption of various metal abrasives in China reaches about 500,000 tons. Among the abrasives used for shot peening strengthening, steel wi...
