1. a continuous casing, injects the molten metal watered in bucket in the tundish of lower section, and the described molten metal in described tundish is injected mold continuously and carrys out casting metal plate, and described continuous casing comprises:

  • Long nozzle setting steps, as the described described molten metal watered in bucket is injected the injection nozzle in described tundish, watering bucket described in being located at by the long nozzle extended in described tundish;

    Implantation step, is injected described molten metal in described tundish by described long nozzle, makes the described molten metal that the sprue gate of described long nozzle is flooded in described tundish;

    First sealed gas supplying step, in described implantation step, as sealed gas to surrounding'"'"'s supply rare gas element of the described molten metal in described tundish;

    Casting step, while the described molten metal in described tundish is flooded at the described sprue gate making described long nozzle, while injecting in described tundish by described molten metal by described long nozzle, the described molten metal in described tundish is injected described mold simultaneously;

    And2nd sealed gas supplying step, in described casting step, replaces the surrounding supply nitrogen of described rare gas element to the described molten metal in described tundish as sealed gas.
