High-chromium Cast Ball Heat Treatment Process Research

Cast grinding balls are solidified in high chromium cast iron to form (CR, Fe)7C3 type carbides, which are discontinuous in the structure, so they have much better toughness than ordinary white iron. In addition, the microhardness of (CR, Fe)7C3 is much higher than that of (Fe, CR)3C carbides in common white iron, and it exceeds the hardest abrasive material commonly encountered in abrasive wear, I, so
