Abstract: The heat treatment process of chrome alloy full casting ball was analyzed, the heat treatment process curve was determined, and the specific measures to improve the wear resistance of high chromium cast ball were put forward. Keywords: high chromium grinding media balls, heat treatment, abrasive resistance Cheng Huajing , Zhangwei (Ma Anshan Dongyou steel […]
Casting Grinding Balls Manufacturing Line is the fully automatic grinding balls production line that produces cast alloyed grinding balls with diverse types, like chrome alloyed, ductile iron type, etc. from dia30mm to 130mm. The whole set of the grinding ball’s line consists of four sections, including the pouring system, sand shooting part, waste sand cleaning […]
The as-cast and austenitic matrix structure can be obtained through the reasonable design of the chemical composition, strict control of each element’s content, and rapid cooling process. The volume content of AUSTENITE is 55% ~ 70%, the amount of carbide is 20% ~ 26%.
Abstract: The production process and main points of high austenitic chromium cast iron grinding ball are introduced. Because of its as-cast austenite structure, it has a high impact toughness. Besides, under impact friction, the microstructure will change to Martensite Matrix, resulting in hardening, which makes the material have high impact wear resistance and high toughness. Production […]
(4) Properties of cr25 high chromium cast iron ball grinding products Metallographic structure: The metallographic structure of CR25 high chromium cast iron grinding ball is tempering, eutectic carbide (Ke) and primary carbon, carbide (K1) are homogeneously embedded in the matrix of fire Martensitic (m), and the particles, grains, second and Secondary Carbides (K2) are uniformly […]
