Heat treatment of high chromium grinding ball is the main method to obtain good wear resistance. The research on high chromium cast iron ball mainly focuses on chemical composition selection, heat treatment process determination, modifier selection, good carbide type and wear mechanism.
Therefore, in order to make the hardness of 50mm high chromium white cast iron grinding ball larger than 60HRC, the optimum austenitizing temperature and holding time are fixed range. Because if the temperature is lower or holding time is not enough, the white cast iron is not fully austenitized and its hardness is lower after quenching.
