摘要
设计了稀土高铬白口铸铁磨球的化学成分、显微组织，测试了磨球的力学性能．采用稀土变质处理细化了组织，进一步提高了磨球的韧性及耐磨性．经工业装机试验，取得了令人满意的结果．
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.
