A plasma-arc furnace comprises a casing with plasma torches, particularly ree torches, mounted therewithin in symmetrical relationship relative to the vertical axis thereof. Each of these torches comprises a body provided with a nozzle and an axial conduit for feeding a plasma-forming gas therethrough, and a cylindrical electrode disposed within said conduit. According to the invention, the distance between the centers of working ends of electrodes disposed within adjacent plasma torches is not more than 15 diameters of the electrode.

Plasma-arc furnace

A plasma-arc furnace for remelting metals and alloys comprising a chamber with openings, which accommodates therein a plasmatron including a consumable electrode with an axial through-going internal space, and a water-cooled rod of a mechanism for moving this plasmatron in a vertical direction, said electrode and said rod being operatively connected with each other, the rod extending into the chamber through one of its openings. The furnace further includes a flexible gas conduit having one of its end portions projecting outwardly through another opening in said chamber and connected to a source of plasma-yielding gas, the other end of this conduit communicating with the internal axial space of said plasmatron. The furnace also includes a water-cooled crystallizer for accumulating liquid metal therein communicating with the chamber, the water-cooled rod and the water-cooled crystallizer being connected to a power supply source.
