Plasma melting uses a mixture of inert gas (such as argon), reducing gas (such as hydrogen) or two gases as a medium, and a pure plasma arc or plasma beam with a temperature above 30 thousand degrees is used as a general term for metallurgy. It can be melted in a furnace with a lining and can be melted and purified in the form of a consumable electrode. It is mainly used for special steel, ultra-low carbon stainless steel, superalloy and the production of active and refractory metals such as tungsten, molybdenum, rhenium, tantalum, niobium, zirconium and so on....More>>
Under vacuum or inert gas protection, consumable electrode made of molten metal rapidly melts and solidifies into ingots in water cooled copper crystallizer under the action of high temperature and low voltage and high current direct current arc....More>>
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...More>>
