ABSTRACT:
The electrode structure, embedded in a refractory lining (1) covering the wall (2) of a vessel containing the bath (5) of metal, flush at one (4) of its ends with the inner surface of the refractory lining and projecting at its other end (6) out of the vessel, is of the type comprising an electrically conductive central core (3) extending through the wall (3) of the vessel and a cooling jacket (11) disposed around the central core (3) and in close contact therewith. The feature of the electrode structure is that the central core (3) is connected by its end (6) outside the vessel to an electric supply terminal (7), the zone of the central core (3) adjacent to the outer end (6) and in facing relation to the cooling jacket (11) being electrically insulated from the cooling jacket.
