Plasma melting

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.
