  • Patent number: 6855241
    Abstract: An apparatus for the smelting of aluminum includes a melting furnace that is separate from and free of permanent interconnection with an electrolytic cell. The melting furnace is preferably an induction melting furnace that is designed for optimum heating and intermixing of a cryolite electrolyte and alumina, and the electrolytic cell is preferably designed for electrolysis of alumina without regard for heating, mixing or dissolving requirements. Methods for operating the apparatus are also described.
    Type: Grant

  • Patent number: 4691758
    Abstract: Two-drum, two-layer continuous casting method and apparatus for casting metallic strip from molten metal in which two closely spaced drums with parallel horizontal axes define the bite region between them. The drums are revolved in opposite directions at approximately the same surface speed with the surface of each drum moving downwardly in the bite region. The two drums are hollow and are internally cooled in a manner to keep their external surfaces at a temperature in the range from and including 100.degree. C. to 400.degree. C. The molten metal flows in a launder at controlled velocity toward the crest of each revolving drum, and the drum surface is travelling at speed faster than this controlled flow velocity, at least 1.
