| 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。

| 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. |
