Abstract
A smelting unit having a furnace vessel (11) which is mounted on a furnace rocking cradle (13) and which can be closed by a cover (12), and bar electrodes (28) which can be lowered into the furnace vessel (11) and which can be raised and lowered by means of electrode lift devices (30), in which the electrode lift devices (30) are carried by a portal assembly (31). In a lowered position the portal assembly (31) lies on a support holder (33) of the vessel substructure (14) or the furnace rocking cradle (13) respectively and in that position can be tilted with the furnace vessel (11). It can be released from the furnace vessel (11) and pivoted to the side by a lift post (43) of a stationary lifting/pivoting mechanism (40). When the unit has two vessels which are arranged side-by-side, the bar electrodes can be associated alternately with one vessel or the other by means of the lifting/pivoting mechanism (40).
