Abstract
721,980. Self-baking electrodes. KAISER ALUMINUM & CHEMICAL CORPORATION. Sept. 12, 1952 [Sept. 13, 1951]. No. 22943/52. Class 39 (3). An electric furnace, e.g. for producing aluminium steel, or calcium carbide, has at least one self-baking electrode 11 comprising a horizontal, elongated, current-carrying, metallic core 12 surrounded by a layer of non-metallic, consumable electrode material, e.g, carbon paste 13, having an upper unbaked portion and a lower baked portion. The paste 13 is fed through a hopper 14, one side 15 of which is arcuately extended at 17 to form, with end plates 19, a mould for the paste 13 while it is being baked. Aluminium foil 22 prevents adhesion of paste 13 to the side 17 during clockwise rotation of the core 12 to introduce paste 13 into the bath 10 above which a plurality of parallel electrodes 11 are rotatably arranged. Rotation is transmitted to the cores 12 by a shaft 28 and worm gears 30 co-operating with gears 26 on extensions 24 of the cores 12, and electric current is led to the cores 12 from a connection 35 through a, conducting liquid 32, e.g. a molten metal, e.g. Hg, Zn, or Pb, in a container 33 in which dips a disc 31 mounted on each extension 24. The cores 12 may be hollow or solid, and may be. roughened on their outer surfaces. The electrodes 11 may be radially arranged about an annular bath 10, and they may, be vertically adjustable.
