  • Patent number: 4771819
    Abstract: Manufacturing apparatus for continuous casting of sheet metal includes a pair of chill rolls and a vessel containing molten metal. One of the rolls is of a larger diameter, on which the other roll of a smaller diameter is arranged at a position corresponding to a clock position of 12-3 O'clock. The vessel has an open forward end and is arranged to contact the larger roll or leave a gap as narrow as possible. The smaller roll is partially disposed in molten metal in the vessel. When the two rolls are driven at the same peripheral velocity in the opposite direction, molten metal is fed between the rolls to form a sheet metal which may be continuously peeled from the larger roll surface.
