ABSTRACT:
A direct-current electric arc furnace for melting metals, including a furnace vessel and at least a pair of electrodes, wherein a bottom electrode is mounted in the bottom of the furnace vessel. In order to be able to remove the bottom electrode, the cross-section of which tapers towards the interior of the furnace vessel, from the outside in the direction of the furnace vessel interior, the bottom electrode is provided with a molded body of a refractory material. The molded body envelopes the bottom electrode and in combination therewith forms an electrode unit. This electrode unit in turn has a cross-section which expands in the direction of the furnace vessel interior or at the most remains the same. In this way, extensive work can be saved by removing the bottom electrode from outside into the interior of the furnace. Removal of the bottom electrode is also facilitated by the fact that neither a connecting piece for applying power to the electrode and for cooling thereof nor the electric feedlines thereto need be removed.
