  • Supplying method for molten alloy for producing amorphous alloy thin strip
    Patent number: 5965052
    Abstract: A method for supplying molten metal alloy for producing thin amorphous metal wire or thin amorphous metal strip by liquid quenching and solidification on a moving cooling substrate controls the flow of molten metal from a ladle into a tundish. The ladle has a long nozzle with an interior passage for providing flow of molten metal alloy into the tundish. The ladle stopper has a distal end region received by the interior passage of the long nozzle. Control of the overlap between the distal end region of the ladle stopper received in the long nozzle during molten alloy flow and control of the sectional flow area provided in the long nozzle interior passage controls the flow quantity of molten alloy from the ladle into the tundish.
    Type: Grant
    Filed: October 23, 1998
    Date of Patent: October 12, 1999
    Assignee: Nippon Steel Corporation
