Abstract (en)

Starting from a continuous casting furnace (1), fed with scraps, ingots or any other aluminum presentation, the cast metal is urged to pass through a solidification and rolling machine (5), a 19 mm-thick aluminum sheet being obtained. Then, this sheet is subjected to three successive hot rolling phases in respective rolling towers (8-8'-8"), attaining at its outlet a 1.5 mm thickness. Then, the aluminum sheet is subjected to two cold rolling phases until attaining a 0.54 mm thickness and, after intermediate annealing, it is subjected to a final cold rolling phase in which the definitive 0.25 mm thickness is obtained. The process achieves cutting the time of 34 hours corresponding to a classic continuous casting process down to 19 hours. <IMAGE>
