  • Continuous casting aluminum alloy
    Patent number: 4751958
    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.
    Type: Grant
    Filed: November 10, 1986
    Date of Patent: June 21, 1988
    Assignee: Hunter Engineering Company, Inc.

  • Continuous casting aluminum alloy
    Patent number: 4681152
    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.
