本项科研成果是将北京钢院研究成功的稀土中锰白口铁在合金成份上稍加调整,在太钢峨口铁矿用于制造研磨高硬度铁矿石的直径三米以上比较大型的球磨的衬板,这在国内是创举。 新型抗磨白口铁是根据几种合金元素综合使用可以最为经济有效地提高钢铁淬透性获得马氏体组织的原理、采用锰为主加元素并辅加少量铜铬镍,即立足国内资源有充足市场供应而且材料成成本低,另外推广应用我国富有的稀土进行白口铁的变质处理、改
The research results of the Beijing Institute of steel rare earth manganese white iron in the alloy composition slightly adjusted in TISCO Ekou iron ore used in the manufacture of high hardness grinding iron ore more than three meters in diameter larger Ball mill liner, which is pioneering in China. The new anti-wear white iron is based on the comprehensive use of several alloying elements can be the most cost-effective way to improve the hardenability of steel to obtain martensite structure principle, the use of manganese plus plus a small amount of copper chrome-nickel element that is based on domestic resources There is sufficient market supply and materials into a low cost, the other to promote the use of rich rare earth white iron processing, change
