ABSTRACT:
An improved cooling method and apparatus for a continuous casting process of the type wherein the mold is a rotatable casting wheel having a peripheral groove with a portion enclosed by an endless band. The improved cooling of the hot cast metal bar is accomplished by injecting a cooling fluid, under pressure, into the shrinkage gap between the hot continuously cast bar and the band portion of the mold after the bar is partially solidified but before it is removed from the wheel portion of the mold. The hydraulic pressure of the cooling fluid forces the band portion of the mold away from the periphery of the casting wheel so as to allow a quantity of cooling fluid to impinge directly on the hot but solidified band-side surface of the cast bar to directly cool the bar, and also to permit a build-up of fluid pressure in the mold which forces the bar firmly into contact with the walls of the peripheral groove and thus eliminates any shrinkage gap therebetween, thereby increasing the quantity of heat transferred from the hot cast bar.
