Abstract A continuous casting process comprises feeding a mol- ten metal into a mould from a metal supply system through a metal feeding duct, effecting a stepwise withdrawal of a continuous strand or casting from the mould 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 with- drawal 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 form- ed. 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 As the casting is withdrawn from the mould for a given length, the molten metal is concurrently fed into the mould from the auxiliary vessel and from the metal supply system. There is also provided an apparatus for performing the above process.
