摘    要:研究了几种复合孕育剂可较高碳当量(CE=3.8%-4.1%)灰铸铁性能的影响,试验并经实际生产结果表明,选择60%SiBa 40%SiFe作为高碳灰铸铁件的复合孕育剂,其抗拉强度稳定在250MPa以上,并能减小白口宽度和断面敏感性,满足实际生产要求,同时对其孕育机理进行了探讨。

关 键 词:复合孕育剂 灰铸铁 高强度 薄壁铸件

Abstract:In this paper,the effects of several com pound inoculants on gray cast iron′s properties with 3.8%~4.1%CE were invest igated.The experiment and production results showed that 60%BaSi+40%SiFe was sel ected as compound inoculants for gray cast iron with 3.8%~4.1%CE,its tensile strength was higher than that of HT250 grade and its sensibility of section hard ness and white iron width were reduced.It meets production requirement.At same t ime its inoculation mechanism was studied.
Keywords:compound inoculants  gray cast iron  high strength  thin section casting
