ABSTRACT:
A method is provided for continuously casting aluminum alloys particularly useful for computer memory disk stock by a combination of casting at thinner gauges and much higher speeds than usual. Sheet quality is vastly improved, surface ripples are avoided, and casting rate increased as much as 50%. The method is characterized by the thickness of the cast sheet being in the range of from 4 to 6 millimeters and the casting rate being in the range of from 0.8 to 1.8 meters per minute. Chlorides in the molten metal are coalesced and oxides filtered to keep the inclusion rate in the cast sheet very low.
