AGITATED CONTINUOUS CASTING PROCESS FOR ALUMINUM ALLOY

摘要

When a continuous casting is carried out while applying an electromagnetic agitating force to a molten metal of an aluminum alloy composition, the molten metal of the aluminum alloy composition, which is used, has an Fe content in a range of 0.75% by weight <=Fe<2% by weight. Thus, a hard Fe-based intermetallic compound can be crystallized as a primary crystallized product, and an acicular intermetallic compound can be pulverized and finely divided by cooperation of the hard Fe-based intermetallic compound with the electromagnetic agitating force.
