Abstract

A continuous casting apparatus has a continuous casting mold which defines a casting passage. The walls of the mold are provided with conduits which are connected with a source of pressurized gas and open into the casting passage at locations downstream of that where the meniscus is normally established. During withdrawal of a continuously cast strand from the mold, gas is injected into the casting passage at a pressure sufficient to force the meniscus away from the walls of the mold. This eliminates the friction which normally exists between the mold and the meniscus so that the mold need not be oscillated during strand withdrawal. The continuous casting apparatus accordingly does not require an oscillating mechanism for the mold.
