Through the reasonable design of the chemical composition, strict control of the content of each element, through metal mold casting process and rapid cooling scheme, as-cast austenite, matrix structure, austenite occupied, volume content 55% ~ 70%, carbide content 20% ~ 26% can be obtained.
Abstract: The production process and key points of austenitic high chromium cast iron grinding ball are introduced. Because of its as-cast austenite structure, it has high impact toughness. In addition, in the condition of impact friction, the microstructure will change to martensite, which will produce a work-hardening phenomenon. The material has high toughness and high […]
