In this paper the effects of the Re-K-Zn compound modificator on the microstructure and properties of high Chromium white cast iron as-cast have been studied by the method of orthogonal design. The results have been analyzed with the aid of scanning electron microscopy and energy dispersive X-ray analyzer.

本文通过正交设计实验研究了Re-K-Zn复合变质剂对高铬白口铸铁组织和性能的影响，借助于电子扫描显微镜、X-射线能谱仪等先进设备对其影响结果进行了分析。

The results show that Re-K-Zn compound modificator has remarkable effects in high Chromium white cast iron when the modificator has 0.5%Re+2.0%K+0.008%Zn. The modificator not only or bar-like carbides but also improved the mechanical properties of high chromium white cast iron,with its impact toughness enhanced from 7.0J/cm2 to 11.7J/cm2 and its hardness enhanced from 54HRC to 57HRC, and the wear resistance increased by 350%.

实验结果表明：Re-K-Zn复合变质剂在高铬白口铸铁中有显著作用，而且当三者的加入量约为0.5%Re+2.0%K+0.008%Zn时，能显著细化组织，使其组织中网状碳化物变为粒状或条状，提高了高铬白口铸铁的力学性能，铸态冲击韧性由原来的7.0J/cm2提高到11.7J/cm2，硬度由原来的54HRC提高到57HRC，相对耐磨性能提高了3.5倍。
