摘要： 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.

摘要： 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.

摘要： According to the invention, there is proposed a feed system for a plasma-arc furnace wherein an electrode with an axial opening is used as the low-temperature plasma generating means. The feed system comprises a gas conduit, in the form of an individual water-cooled member, a current-conducting element mounted within a shell and secured to a flange which includes a duct for the delivery of gas, a duct for feeding flux, and a duct for supplying water. The flange has secured to it the shell. A flux delivery means and a bus for power supply are also included. The herein proposed feed system makes it possible to assure stable operating conditions of a plasma-arc furnace, enhance its efficiency, reduce power losses and decrease expenses involved in the remelting of metals and alloys.

摘要： Nonconsumable electrode for melting metals and alloys, comprising a housing with a hollow fluid-cooled tip. On one of the tip's side-walls, on the side of the cavity, there is at least one threaded groove. This side wall with the threaded groove on it serves as a means for the rotation of the arc which is actuated between the tip and a metal or alloy to be melted.
