Abstract

The invention discloses a wearable steel ball with a reinforced framework. The wearable steel ball comprises the framework and a metal base body formed by casting a metal alloy on the framework, wherein the framework is of an integrated structure and is used for separating a space inside the steel ball into a plurality of spaces, and the metal base body is filled inside the framework and covers the framework. The wearable steel ball with the reinforced framework, disclosed by the invention, has good impact resistance and surface strength, and is easy to recycle and high in use efficiency.

Description

technical field [0001] The invention relates to the technical field of grinding machinery, in particular to a skeleton-reinforced wear-resistant steel ball. Background technique [0002] Ball mill is one of the high-fine grinding machines widely used in industrial production. The steel ball of the ball mill is the grinding material medium of the ball mill equipment. The grinding effect is produced through the collision and friction between the steel balls of the ball mill and between the steel ball and the material. It is an important basic component, especially the precision industrial steel ball plays an important role in the development of the national economy. has a huge effect. According to the data and practice, in the fatigue loss of the grinding medium steel ball, the damage of the surface layer of the steel ball (such as micro pitting, corrosion, surface fatigue damage and plastic deformation, etc.) accounts for the majority. Moreover, most of the grinding medium ...
