Title: Innovations by John E Flowers in Aluminum Alloy Casting
Introduction
John E Flowers is a notable inventor based in Riverside, CA (US). He has made significant contributions to the field of aluminum alloy casting, holding 2 patents that showcase his innovative methods. His work has greatly improved the quality and efficiency of aluminum sheet production.
Latest Patents
One of his latest patents is focused on a method for continuously casting aluminum alloys with more than two percent total alloying elements. This method allows for casting at thinner gauges and much higher speeds than usual. By avoiding remelting in the caster, the quality of the sheet is vastly improved, and surface ripples are eliminated. The casting rate can increase by as much as 50%, with the thickness of the cast sheet ranging from 4 to 5.8 millimeters and the casting rate between 1.3 to 1.9 meters per minute. Additionally, chlorides in the molten metal are coalesced, and oxides are filtered to maintain a very low inclusion rate in the cast sheet.
Another patent by John E Flowers also focuses on continuously casting aluminum alloys, particularly useful for computer memory disk stock. Similar to his first patent, this method emphasizes casting at thinner gauges and higher speeds. The quality of the sheet is significantly enhanced, and surface ripples are avoided, with a casting rate increase of up to 50%. The thickness of the cast sheet in this method ranges from 4 to 6 millimeters, and the casting rate is between 0.8 to 1.8 meters per minute. The process also ensures that chlorides and oxides are effectively managed to keep the inclusion rate low.
