Abstract
In a slab continuous casting machine comprising a tundish for reserving a molten steel therein, a nozzle holding cassette disposed on an outer bottom portion of the tundish, a mold for use in a casting, and an immersing nozzle mounted in the nozzle holding cassette and for pouring the molten steel in the tundish into the mold, the cavity has a generally rectangular sectional shape defined by a pair of short sides and a pair of long sides. When the immersing nozzle is inserted into the mold and when the immersing nozzle is taken out from the mold, a movement of the immersing nozzle gripped by a handling arm in the mold is limited in a direction parallel to the pair of short sides.
