High-chromium alloy wear-resistant steel ball and processing method thereof

Abstract

The invention discloses a high-chromium alloy wear-resistant steel ball and a machining method thereof, and belongs to the technical field of high-chromium alloys, the high-chromium alloy wear-resistant steel ball comprises a wear-resistant steel ball main body, an outer friction semi-arc ring is arranged on the surface of the wear-resistant steel ball main body, and the outer friction semi-arc ring is used for enhancing friction connectivity between the wear-resistant steel ball main body and an object. An oscillation counteracting shaft is arranged in the wear-resistant steel ball main body, the oscillation counteracting shaft is used for reducing the impact force in the ball body, and the inner side of the outer friction semi-arc ring is fixedly mounted on the surface of the wear-resistant steel ball main body. Through combination of the outer friction semi-arc ring, the first reinforcing outer layer and the second reinforcing outer layer, the problems that in the using process of an existing wear-resistant steel ball, friction connection between the wear-resistant steel ball and an object is not high, and the using effect of the steel ball is easily reduced are conveniently solved, and through the structural combination, the wear-resistant steel ball can not be damaged easily in the using process. The friction connectivity between the steel ball and an object can be enhanced through the outer friction ring, so that the use effect of the steel ball is improved.

Description

technical field [0001] The invention relates to a wear-resistant steel ball and relates to the technical field of high-chromium alloys, in particular to a high-chromium alloy wear-resistant steel ball and a processing method thereof. Background technique [0002] High chromium cast iron is the abbreviation of high chromium white wear-resistant cast iron. It has much higher wear resistance than alloy steel, and much higher toughness and strength than ordinary white cast iron. At the same time, it also has good high temperature resistance and corrosion resistance, combined with convenient production and moderate cost. Known as one of the most excellent anti-abrasive wear materials in contemporary times. There are following problems at prior art: [0003] 1. In the existing technology, there is a problem that the existing wear-resistant steel ball cannot be frictionally connected to the object during use, and the use effect of the steel ball is easily reduced; [0004] 2. In...

Problems solved by technology

[0005] The technical problem to be solved in the present invention is to provide a high-chromium alloy wear-resistant steel ball and its processing method, one of which is to have an outer friction half-arc ring, a first reinforced outer layer, and a second reinforced outer layer to solve the current Some wear-resistant steel balls cannot be connected to objects with low friction connection during use, and the use effect of the steel balls is easy to decline; another purpose is to solve the problem that the existing wear-resistant steel balls are in use. Since the inside of the steel ball is solid, it is impossible to reduce the force of the impact after being hit, resulting in the problem of the ball breaking, so that the wear-resistant steel ball can reduce the force of the impact inside the ball when it is in use. Prevent the sphere from shattering upon impact
