摘要
本文在实验室和工厂条件下研制了与高铬铸铁磨球相匹配的衬板新材质—稀土铬硼抗磨铸铁，取代传统应用的高锰钢（ZGMn13）衬板，使用寿命提高1～2倍．
A new wear - resisting materials was studied in this paper. The experimental results show that the rare-earth chromium boron cast iron is better than the high-chromium cast iron and the ZGMn13 steel in the wear resistance. Working life of liner plate is two times larger tban ZGMn13 steel.
