Abstract
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.
