ABSTRACT:
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.
