ABSTRACT:
A system and method for continuous casting involves performing low-head casting within a highly electrically conductive shield/mold to block out an electromagnetic field that exists below the shield/mold. In this respect, the shield/mold and the electromagnetic field primarily cooperate to provide an environment in which low-head continuous casting can be safely carried out under controlled conditions. In one embodiment, the shield/mold is constructed of aluminum and a molten metal meniscus extends 1/2-to-11/2 inches above the bottom of the shield/mold. The shield/mold is normally not in contact with the ingot being cast.
