| Abstract: | The chemical composition and microstructure of grinding balls of high Chromium withe cast iron with RE are designed.The mechanical properties of grinding balls are tested. The fine microstructure is obtained,and toughness and abradability of grinding balls are increased significantly by modification with RE.After industrial testing,a satisfactory result is achieved. |
