摘　　要：简述了冷坩埚感应熔炼活性金属的发展过程,较详细地介绍了美国USBM公司感应渣熔工艺及Duriron公司感应凝壳炉精密铸造的生产应用情况。对冷坩埚感应熔炼过程中的磁场增强效应及搅动驼峰的形成作了分析,指出该工艺无需制作电极即可得到成份均匀的高质量铸件。对近年来冷坩埚感应熔炼工艺,在一些国家中的工业化应用情况也作了介绍。This paper describes the development history of the cold-crucible induction process for melting reactive alloys. The induction slag melting process of USBM and the induction skull investment casting process of Duriron are demonstrated for commercial applications. The strong magnetic field effect and the formation of strring peak were discussed for the cold-crucible induction melting process. High quality casting with homozeneous chemical composition can be obtained without fabrication of elctrodes. The recent commercial applications in some countries arc also summarized for the cold-crucible induction melting process.
