ABSTRACT:
A billet continuous casting machine comprises, a jacket for cooling an outer wall of a quadrangular tubular mold with cooling water, electromagnetic brakes disposed outside the mold and decelerating the flow of poured molten metal in the mold, an X ray-based level sensor for detecting the level of molten metal in the mold, notched portions formed at the corners of a quadrangular lower part of the mold, spray nozzles for spraying a cooling liquid directly onto the notched portions, and elastically pushing unit for imparting a pushing force corresponding to the static pressure of the molten metal to unnotched portions of the quadrangular lower part of the mold to push the unnotched portions inwardly of the mold, whereby molten metal is continuously poured into the cooled mold to solidify the molten metal so that a cast piece quadrangular in cross section is continuously produced. Delay in solidification at sites near the corners of the cast piece is eliminated, and high quality, high speed casting is realized.
