Method and apparatus for forming aluminum ingot having shaped ends to avoid alligatoring during rolling.

Shaped direct chill aluminum ingot

A series of inventions leading to the production of specific aluminum alloys (especially aluminum beverage can sheet product) through novel approach of introducing, selectively partitioning and managing alloying elements. This invention also enables manufacturing practices to enhance the performance characteristics of aluminum alloys produced. The selected elements can be derived from carbon anodes made from calcined petroleum coke with high metallic contents (such as nickel and vanadium). Alloying elements can also be introduced and managed from other raw material such as alumina and bath constituents added during aluminum smelting process. Additionally, cell operating parameters, such as cell temperature, off gas flow rate, aluminum tapping rate and impurity partition characteristics can also be manipulated to produce low cost aluminum alloys and facilitate utilization of high metallic content calcined petroleum coke.
