ABSTRACT:
An electrode comprises an outer casing and an inner casing which enclose un-baked electrode paste. A conducting mandrel is placed in the center of the electrode and is in electrical contact with the paste. Electric current passes through the conducting mandrel outwardly through the paste to provide a baked electrode. Slipping shoes engage the outer surface of the baked electrode to support the baked electrode and the unbaked paste. In one embodiment, a thin foil moves with the paste to allow the paste to move downwardly easily with respect to the casings, and in a second embodiment, the casing is oscillated with respect to the paste to prevent adhesion between the paste and the casing walls.
