据报道,美国扁钢公司(伊利诺州诺斯西卡科)计划以铌、钽合金的高纯化、大型化为目标,投资2300万美元,将大型的电子束熔炼炉与真空电弧炉(2座)等新式设备安装在马斯科吉工厂,电子束炉从1988年开始正式起动,规模为年产450t。不管用户对铌、钽制品的要求是军用还是民用,朝着更高纯的金属、合金以及更大型锭、宽幅板、锻造品方面发展的倾向性增大。面对此一形势,该公司正在推行相应的对策。马斯科吉工厂现存的电子束熔炼炉只能生产直径为25～28cm 的合金锭,而新安
It is reported that U.S. flat steel company (North Silesian Illinois) plans to invest $ 23 million in the high-purity and large-scale production of niobium and tantalum alloys by combining large electron beam melting furnaces with vacuum electric arc furnaces Block) and other new equipment installed in Muskogee factory, electron beam furnace officially started from 1988, the scale of an annual output of 450t. Regardless of the user requirements for niobium and tantalum products military or civilian, the tendency towards more pure metals, alloys and larger ingots, wide panels, forging products to increase. Faced with this situation, the company is implementing the appropriate countermeasures. Muskogee’s existing electron beam melting furnaces produce only alloy ingots 25 to 28 cm in diameter,
