Abstract
The sizes of 14S, 24S, and 75S aluminum-alloy ingots needed for the United States Air Force large-press program are estimated and compared to the size of ingots cast in current production. The direct-chill process is selected for development of the casting of large ingots. Quality required, metallurgical factors involved, equipment used, and casting variables are discussed. Experimental results in casting 14S aluminum-alloy ingots weighing up to 12,000 lb are presented. An opinion is expressed on the future production of large aluminum-alloy ingots for use in extrusion and forging presses up to 25,000 and 50,000 tons capacity, respectively.Keywords
