Abstract: A method of making a rolled aluminum product comprises sawing an aluminum ingot so that the ingot is separated into at least two separate aluminum slabs and rolling at least one of the slabs unclad and unbrazed. In some embodiments, the ingot is sawn horizontally, across its face, as so that, the slabs are equal in length to the ingot. In some embodiments, at least one of the slabs is rolled to form a one of a plate, sheet or foil. The rolling can be hot rolling or cold rolling. Some embodiments further comprise scalping the aluminum ingot. In some embodiments, the sawing of the ingot eliminates or reduces the need to scalp the aluminum ingot and scalping is not performed. Some embodiments further comprise sawing curved edges off the aluminum slabs.

Abstract translation: 制造轧制铝产品的方法包括锯切铝锭，使得锭被分离成至少两个分开的铝板坯，并且轧制至少一个板坯，并且未被切割。 在一些实施例中，铸锭水平地锯切其表面，使得板坯的长度与锭块相等。 在一些实施例中，至少一个板坯被轧制以形成板，片或箔中的一个。 轧制可以是热轧或冷轧。 一些实施例还包括刮削铝锭。 在一些实施例中，锭的锯切消除或减少对铝锭头皮的需要，并且不执行剥皮。 一些实施例还包括从铝板锯切弯曲的边缘。
