Abstract
A continuous casting process and apparatus for feeding a molten metal into a mold from a metal supply system through a metal feeding duct, effecting a stepwise withdrawal of a continuous strand or casting from the mold for a measured length and simultaneously feeding a molten metal into the latter, producing a superpressure on the forming skin of casting at the side of molten metal at intervals between the casting withdrawal cycles. On completion of the withdrawal cycle, the molten metal is fed from the metal supply system to an auxiliary vessel prefilled with an inert gas, whereupon a preset pressure is built up in the molten metal inside the auxiliary vessel and in the casting being formed. Next, the molten metal is moved to and fro between the auxiliary vessel and the metal feeding duct of the metal supply system. As the casting is withdrawn from the mold for a given length, the molten metal is concurrently fed into the mold from the auxiliary vessel and from the metal supply system.
