  • Patent number: 4527329
    Abstract: A process of forming a continuous carbon electrode for use in a smelting furnace in situ is disclosed. The process consists of at least two annular members, the first annular member provides the heat for softening, and baking the electrode paste to form a solid carbon electrode and the second annular member provides the electric current for the furnace. The second annular member receives energy independent of the first annular member. The weight of the electrode is supported either by the first annular member or by a third annular member which is added between the first two annular members.
