ABSTRACT:
An electric arc furnace for melting metal, especially steel, includes a container having an upper open ended substantially cylindrical wall portion and a lower cylindrical wall portion extending downwardly therefrom and being closed at the bottom and receiving during operation of the furnace a bath of molten material having an upper level at a predetermined maximum elevation above the bottom of the container. The container includes an outer metal shell and refractory material covering at least the lower wall portion of the shell and the closed bottom. In order to increase the charging volume of the container without essentially changing the height thereof, the upper wall portion has, at a distance of at least 300 mm above the level the bath of molten metal, an inner diameter which is greater than the outer diameter of the metal shell of the lower wall portion.
