<p>The object of the invention is a direct current electric furnace for melting a ferrous raw material such as scrap iron, comprising a vessel (1) closed by a removable cover (13), at least one consumable electrode (5) passing through at least one aperture (16) in the cover (13), at least one stationary electrode (50) placed at the bottom (2) of the vessel (1), and at least one direct current source, said vessel (1) being bounded by a bottom (2) shaped as a basin (21) and a side wall (12). According to this invention, the height (H1) and cross-section (S1) of the basin (21) are determined according to the operating conditions so that the basin (1) may contain a prescribed quantity of molten metal, with the height (H2) of the side wall (12) of the vessel (1) being such that the vessel (1) is capable of containing a sufficient load of scrap iron (7) to provide, in a single melting operation, said prescribed quantity of molten metal.</p> |
