摘　　要：1200 kW电子束熔炼炉是一种高真空快速熔炼提纯设备,目前已广泛应用于金属铌和钽及其合金铸锭的熔炼和大规格高纯铸锭的提纯熔炼的生产中。1200 kW电子束熔炼技术的主要优点:熔炼功率、熔化温度和熔炼速度可灵活控制;铸锭产品规格最小可熔炼直径100 mm铸锭,最大可熔炼直径500 mm铸锭;使中国在钽和铌的熔炼提纯方面达到了国际先进水平。目前已经实现工业化生产,年产量可达450 t,所熔炼的钽和铌及其合金铸锭产品成分优良,完全满足了国内外市场的需要。Electron beam melting furnace is a high vacuum rapid melting purification equipment, purification melting has been widely used in ingot melting of metal niobium and tantalum as well as their alloys. The main ad- vantages of electron beam furnace： melting power, melting temperature and melting speed can be controlled flexi- bly, Ingot product specifications from minimum diameter of 100 mm to maximum diameter of 500 mm. Melting pur- ification of tantalum and niobium in China has reached the international advanced level. Industrialized production has been realized with an annual output capacity of 450 tons. The composition of alloy ingot product is excellent, fully satisfying the needs of the market at home and abroad.
