ABSTRACT:
A method is provided for continuously casting aluminum alloys having more than two percent total alloying elements by a combination of casting at thinner gauges and much higher speeds than usual. Since remelting in the caster is avoided, sheet quality is vastly improved, surface ripples are avoided, and casting rate increased as much 50%. The method is characterized by the thickness of the cast sheet being in the range of from 4 to 5.8 millimeters and the casting rate being in the range of from 1.3 to 1.9 meters per minute. Chlorides in the molten metal are coalesced and oxides filtered to keep the inclusion rate in the cast sheet very low.
