ABSTRACT:
An electrode assembly for a furnace having a refractory lining. The electrode assembly has a conductive casing which houses a replacement body. The casing is sheathed by a conical refractory component with the broad end of the component disposed at the exterior of the furnace and the narrow end adjacent the head of the electrode. The replacement body of the electrode has a central bore, a chamber at the head of the electrode, an annular slit defined between the replacement body, and an outlet through which a cooling fluid is circulated by a suction pump connected to the electrode through the outlet. The electrode head is arranged in the refractory lining of the furnace to provide a space for the deposit of solidified molten melt which forms a protective layer over the electrode head.
