ABSTRACT:
The mold comprises a generally rectangularly shaped, machine duplicatable band which is monolithically circumferentially continuous and inherently convexly bowed on the relatively longer and shorter sides thereof, so that it forms crowns on the opposing side walls of the ingot operatively formed therein. The bow in the relatively longer sides of the band has an inherent deflection adapted to form a crown intermediate between that adapted to compensate for shrinkage during the butt forming stage of the casting operation, and that adapted to compensate for shrinkage when the casting operation is conducted at operating speed. However, the relatively longer sides of the band are adapted to flex laterally inwardly and outwardly thereof, and there are drive means connected with the relatively longer sides of the band to flex the same, firstly relatively laterally inwardly thereof to alter the deflection to that adapted to compensate for shrinkage during the butt forming stage, and then relatively laterally outwardly thereof to alter the deflection to that adapted to compensate for shrinkage when the casting operation is conducted at operating speed.
