ABSTRACT:
Mill processing of ingots and like metal articles at or after bringing to temperatures above about 900.degree. C. is enhanced through self-heat soaking at such high temperatures to homogenize temperature and structural parameters throughout the body of such article. In particular this improves workability of such article for forging or rolling. The insulation comprises thin metal foils or the like separated by alternating layers of subdivided fibrous insulation, preferably in felted, woven or other sheet form and structured to maintain structural integrity at such high temperatures, and provides insulation of the metal article surrounded by such insulation and reduces scale formation and eliminates the need for flame or other external heat source or the need for heavy and/or voluminous handling and furnace equipment.
