Title: THE AIR MELTING OF IRON-ALUMINUM ALLOYS

Abstract

Low-carbon Fe is induction melted without a slag in a rammed magnesia crucible. At the beginning of melt-down Al pig (99.95% Al) charged in a clay- graphite bottompouring crucible is placed in a pot furnace at 1800 deg F. The primary deoxidation of the molten Fe after melt-down is effected by the addition of 0.1% Al and 0.5% Mn. A more drastic deoxidation designed to reduce the O/sub 2/ content to the lowest possible level is accomplished by plunging metallic Ca to the bottom of the melt. The aluminum, which has been removed from the holding furnace, is then H/sub 2/ degassed by bubbling Cl/sub 2/ through a quartz tube immersed in the molten Al. About 0.1% Ca is then added to the Al, the oxide dross is removed, fluorspor is added to the molten Fe, and the molten Al is poured through the fluorspar slag. After vigorous stirring, the melt is poured into cast-iron molds. Ingots are removed from the molds and buried in vermiculite, where they are allowed to cool to room temperature. The ingots are radiographed, cropped, and heated to 1800 deg F for breakdown. The ingot is then rolled. (A.C.)
