  • Patent number: 3998365
    Abstract: Molten metal is poured, in at least two successive operations, from a container having an interior closed off substantially gas-tightly and provided with a pour-out conduit which has an inlet communicating with the interior of the container and which has an outlet pouring opening located outside the container above the highest level to which molten metal in the container interior is permitted to rise. The metal in the conduit is established at a predetermined starting level prior to the start of the first pouring operation by feeding pressurized gas into the space above the molten metal in the container interior. Thereafter, each pouring operation is effected by boosting the gas pressure in such space by an amount requisite to effect pouring out through the pouring opening of the quantity of molten metal to be dispensed.
