ABSTRACT:
In a method of manufacturing amorphous metal ribbons by ejecting molten metal through a nozzle attached to a tundish onto a rapidly moving cooling body, the molten metal is suppled to the tundish by first pouring the molten metal from a ladle into an intermediate vessel and then by supplying the molten metal from the intermediate vessel to the tundish through a gas-lift pump. An apparatus for supplying molten metal to a tundish comprises an intermediate vessel adjacent to the tundish and a gas-lift pump to supply the molten metal from the intermediate vessel to the tundish. The molten metal is poured from a ladle into the intermediate vessel. The gas-lift pump has a pump proper that is placed over the intermediate vessel and tundish so that its inlet and outlet open in the intermediate vessel and tundish, respectively. Bubbles are suppled into the pump proper through its inlet.
