Abstract: The classification of electro-slag metallurgy, the characteristics of first and secondary generation of electroslag metallurgical technology, the stage of development history of electro-slag metallurgy, the development of first and secondary generation of electro-slag metallurgical technology, and the orientation for further development of secondary electroslag metallurgy have been reviewed. It is pointed out that the first generation of electro-slag technology was developing accompanied with progress in eletro-slag remelting heavy-ingot, and with the rapid progress of nuclear power station, the optimum design of heavy equipment and optimum production technology for the secondary generation of electro-slag metallurgical technology should be realized to control remelting atmosphere, remelting and solidification process, and to increase computer control standard.

Key words: Secondary Electro-Slag Metallurgical Technology,Heavy Electro-Slag Remelting Ingot, Inert Gas Atmosphere, Quick Cooling, Orientation for Development

摘要： 论述了电渣冶金技术的分类,第一代和第二代电渣冶金技术的特点,电渣冶金发展历史的分期,第一代和第二代电渣冶金技术的发展,第二代电渣冶金进一步发展的方向。指出第一代电渣重熔技术是伴随电渣重熔锭大型化发展起来的,随着核电技术的迅速发展,第二代电渣重熔技术应实现大型装备优化设计、气氛可控制、重熔和凝固过程可控制,并提高计算机控制水平。
