Abstract
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.
