Abstract: Plasma smelting has a series of features which can accelerate heat transfer, material exchange and chemical reaction processes, thus strengthening smelting process. It can be used together with other smelting methods to form plasma electroslag process, plasma induction remelting process, etc. It has an irreplaceable role in the smelting of refractory metals, the cultivation of refractory metal single crystals, the refining of active metals, and the recycling of precious metals.

Key words: plasma technology, smelting, foundry, plasma welding
