A plasmarc furnace for remelting metals and alloys in a controlled atmosphere, which comprises a hollow consumable electrode disposed in a crystallizer and an arc plasmatron with a nonconsumable electrode disposed above the hollow consumable electrode coaxially therewith. A hollow rod is provided above and coaxial with the arc plasmation driven by a vertical travel mechanism and insulated from the arc plasmatron leads. The plasma-forming gas is delivered to the plasma discharge zone by a plasma-forming gas supply and flow rate control system via a gas conduit defined by the cavities of the hollow rod, the arc plasmatron and the hollow consumable electrode. The crystallizer and hollow rod are coupled to the opposite poles of the power source.

Plasmarc furnace for remelting metals and alloys

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.
