| 摘 要： | 研究变质处理对钨渣低铬（Ｃｒ≤２％）耐磨铸铁显微组织、力学性能及抗磨性的影响。结果表明，用含Ｖ、Ｘ和Ｂ的变质剂处理钨渣低Ｃｒ耐磨铸铁，可使其组织中的碳化物由连续网状粗大的板块状，转变为孤立细小的块状；冲击声望生提高１８０％；抗磨性提高８５％左右。

| Abstract: | In this paper, effects of modification on the microstructure, mechanical properties and abrasive resistance of W slag low Cr wearproof cast iron are investigated. The results obtained show that the morphology of carbide in the W slag low Cr white cast iron treated with the ino-culans containing V,Re and B is changed from continuous network to isolated, fine irregular blocks and at the same time,the impact toughness was increaed by 120%,and abrasive resistance by 40%. |
