Abstract
A method of producing aluminum can sheet having high strength and low earing characteristics comprises providing an aluminum alloy ingot and then hot rolling the ingot in a single-stand hot reversing mill to produce a first intermediate gauge sheet. The first intermediate gauge sheet is then cold rolled to produce a second intermediate gauge sheet. This second intermediate gauge sheet is passed through a heat source as a single web so that the second intermediate gauge sheet is continuously annealed. After heating, the second intermediate gauge sheet is quenched and coiled again. Finally, the coiled second intermediate gauge sheet is cold rolled again to produce the final gauge aluminum can sheet having high strength and low earing characteristics.
