Abstract

The present invention provides one kind of stainless steel ball and solves the problems of rusting, impact resistance and friction resistance of blasting metal surface while providing corresponding steel ball producing method and apparatus. The stainless steel ball has chemical components include, C, Si, Mg, Cr, Ni and B. The stainless steel ball product has bright and no-rust surface, no need of heat treatment and ball milling, long service life and high blasting and polishing efficiency, and may be used in sand blaster and shot blasting machine to treat various parts of non-ferrous metal,steel and other material in various fields.

Description

technical field [0001] The invention relates to a metal product and its processing method and equipment, in particular to a stainless steel shot and its processing method and equipment. Background technique [0002] Metal surface treatment includes rust removal, polishing and so on. In the fields of non-ferrous metals, casting and stainless steel casting, metal surface treatment is an indispensable process, which plays a very important role in the quality of products and projects. Shot peening is one of the commonly used methods for metal surface treatment. The traditional shot peening technology uses steel shot and steel grit made of ordinary carbon steel, which has a short service life and is easy to pollute the environment. The surface of ordinary steel shot is easy to oxidize and produce rust, and its impact resistance and abrasion resistance are not strong. During the spraying operation, a large amount of dust will be formed and distributed in t...
