摘　　要：阐述了稀土复合变质剂制取稀土过冷石墨铸铁的方法；对稀土过冷石墨的形成条件及对机械性能影响进行了分析；该铸铁的抗拉强度达到３００ＭＰａ，耐磨性是普通灰铁的２０倍，是一种综合性能优良的新型铸铁材料。The method of producing the undercooling graphite cast iron by rare earths complex is presented. The forming condition of undercooling graphite by inoculating rare earths complex and its effects on mechanical properties of the cast iron are analysed. The tensile strength is 300MPa, the abrasion resistance is 20 times as strong as that of gray iron(HT200), the undercooling graphite cast iron inoculated with rare earths complex is a new type of material with excellent properies.
