近来,美国汤姆斯卡尔冶金公司研究出一种最新的真空熔炼法-用电子注真空炉生产超纯金属的方法(电子注真空熔炼法)。接着应用这一方法的有斯达夫化学公司及玛罗利、塞尔朗金属公司。所用设备如图1、图2及图3所示。电子注真空熔炼炉有单电子枪和双电子枪两种。如图1。这种方法的实质是利用电子枪(作为阴极)发射高压电子注轟击原料(阳极)产生的热量,将要熔炼的原料(阳极)熔化于用水冷却的坩埚中(熔融金属 Recently, the United States Tomskar Metallurgical Company developed a new vacuum melting method - the use of electronic injection vacuum furnace production of ultra-pure metal (electron injection vacuum melting method). Followed by the application of this method are Stav Chemical Company and Mali Li, Serang Metal Company. The equipment used is shown in Figure 1, Figure 2 and Figure 3. Electronic note vacuum melting furnace has a single electron gun and two electron guns. Figure 1. The essence of this method is the use of an electron gun (as a cathode) to emit high-voltage electrons to bombard the heat generated by the raw material (anode), melting the raw material (anode) to be melted in a water-cooled crucible
