Electron beam furnace introduction
The electric furnace is bombarded with high-speed electrons to heat the molten electric furnace (illustrated by the electron beam furnace of Fig. 4). In the vacuum furnace shell, the cathode is heated by a low-voltage electric filament to emit electrons, and the electron beam is accelerated by the action of the high-voltage electric field of the accelerating anode, bombarding the metal material located at the anode, and converting the electric energy into heat energy. Since the electron beam can be highly dense by the electromagnetic focusing device, it can generate a high temperature at the portion where the material is bombarded. Electron beam furnaces are used to melt special steels, refractory and reactive metals.
