Production application of austenitic base high chrome cast iron grinding balls (2)
/in Grinding media balls /by Sara WuThe 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%.
Production application of austenitic base high chrome cast iron grinding balls (1)
/in Grinding media balls /by Sara WuAbstract: 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 […]
