ELECTRON-RAY FURNACES TO MELT REFRACTORY AND REACTIVE METALS

摘要

The LEW combine and Manfred von Ardenne Research Institute (GDR) developed a broad range of electron-ray EMO netting installations with electron guns having capacities of 80, 250, 600, and 1200 kW. Furnaces in this series are operating in the GDR, the USSR, and other countries. In the GDR, at the non-ferrous metals research institute in Freiberg, an electron-ray furnace is used with a gun capacity of 80 kW. It is used to produce tantalum ingots from scrap and baked Holdings as fillers from synthetic fibers. When special technological methods are used to provide for a uniform distribution of alloying elements, the furnaces can melt out homogeneous ingots of the niobium-1 percent zirconium alloy to produce parts for sodium lamps, despite the fact that at the niobium Belting point, zirconium has a much higher vaporization rate.
