Abstract
Provided herein are systems and methods for producing thick gauge aluminum alloy articles such as plates, shates, slabs, sheet plates or the like. A method for producing thick gauge aluminum alloy articles can include continuously casting an aluminum alloy article and hot or warm rolling the aluminum alloy article. Also provided herein is a continuous casting system for producing thick gauge aluminum alloy articles. The disclosed thick gauge aluminum alloy articles can be provided in any suitable temper.
Claims12
A method for producing rolled aluminum alloy articles, comprising:
- providing a molten aluminum alloy;
- continuously casting an aluminum alloy article from the molten aluminum alloy;
- reheating the aluminum alloy article after continuously casting, wherein the reheating the aluminum alloy article comprises reheating the aluminum alloy article to a peak metal temperature from 420° C. to 580° C. and maintaining the peak metal temperature for a duration consisting of 1 minute to 5 minutes;
- quenching the aluminum alloy article after continuously casting with a quenching device;
- and
- after quenching and reheating, rolling the aluminum alloy article at a rolling temperature from 300° C. to 580° C. to a gauge of 4 millimeters (mm) or greater to produce a rolled aluminum alloy article.
