ABSTRACT:
The casting wheel of a continuous casting machine is cooled by a conventional external spray cooling system, but the continuous band looped around the casting wheel to close a predetermined segment of it and thereby form a continuous moving mold cavity is not directly cooled. Rather, the band incorporates a layer of heat-insulative sheet material to deter heat transfer from molten metal introduced into the mold cavity through the band. The result is that the metal solidifies in a direction generally radially outward from the casting wheel toward the insulated band. Shrinkage of the metal occurs primarily adjacent to the band so as to eliminate or reduce internal shrinkage cracks and voids.
