°£Á¢ÀüÈ£·Î(indirect arc furnace)

Electric arc furnaces are used for melting high-melting-point alloys such as steels. The furnace consists of a saucer-shaped hearth of refractory material for collecting the molten metal, with refractory material lining the sides and top of the furnace. The roof can normally swing away to facilitate charging of the furnace. Two or three carbon electrodes penetrate the furnace from the roof or the sides. Doors in the side of the furnace allow removal of alloys, removal of slag and oxygen lancing. The scrap metal charge is placed on the hearth and melted by the heat from an electric arc formed between the electrodes(indirect arc furnace).
