摘要
通过稀土、镁和钛对Mn6钢进行复合变质处理,使其铸态组织明显细化;利用铸造余热对变质Mn6钢铸件进行水韧处理,可简化铸件的生产工艺,降低生产成本;由此获得了具有优异耐磨性能的中锰铸钢,在低冲击功磨损条件下其耐磨性比普通Mn13钢提高80%。经过秦皇岛港务局大量应用,收到了显著的综合效益。
Mn6 steel was multimodified using Re-Mg-Fe and Ti-Fe alloys, which refined the as-cast microstructure of Mn6 steel. The cast was directly quenched using the casting-heat, which can simplify the manufacture process of the casting and reduce the manufacture cost of the casting. The wear resistance of Mn6 steel obtained by this process was increased efficiently. Under low impact energy wear conditions the wear resistance of the Mn6 steel was 1.8 times of ZGMn13 steel. It has been widely used to manufacture the wear resistant lining of transport coal machinery in Qinhuangdao Port. A good benefit was obtained in practice.
