<p>1. Electric furnace including a tub-shaped lower part (1) and an upper part (2) placed on said lower part (1), through whose lid (3) or side walls electrodes (4) or plasma burners project into the furnace interior (5), the lower part (1) having a projection (8) reaching outwardly beyond the wall (15, 15', 20) of the upper part (2) in a bay-like manner on at least one side (7), the bottom (10) of which projection accomodates the tap hole (11), characterized in that the wall part (15) that faces the tap hole (11) of the upper part (2) is retracted with respect to the central axis (16) of the upper part (2) and the radial distance (a) of the retracted wall part (15) from the furnace central axis (16) is smaller than the distance (b) of the radially opposite wall part (20).</p> |
