Working principle of EB furnace

EB furnace smelting principle and X ray tube, which is made of tungsten cathode block by electrified filament indirect heating to 2600~2800 DEG C, the thermal motion of free electrons inside intensifies, when it could reach the electronic work function, from the cathode block the escape of electric force generated in the high voltage electric field under the action of the electron beam, high speed directional movement, and the kinetic energy is converted into internal energy, will target the molten metal
