Patent number: 4960163Abstract: An apparatus and method of casting a melt into an ingot possessing a fine grain structure. The apparatus comprises (1) a casting mold for holding a reservoir of melt; (2) a partition means located in the melt for dividing the melt into a melt supply reservoir located on a first side of the partition means and a solidification reservoir on a second side of the partition means, the partition means having a communication means for permitting melt to flow from the melt supply reservoir to the solidification reservoir, the partition preventing turbulence from the solidification reservoir to be transferred to the surface of the melt; and (3) means for stirring the portion of the melt located in the solidification reservoir. The means for stirring provides nuclei for grain refinement of the ingot.Type: GrantFiled: November 21, 1988Date of Patent: October 2, 1990Assignee: Aluminum Company of AmericaInventors: Que-Tsang Fang, Michael J.

Patent number: 4767598Abstract: An injection apparatus for introducing fluid material, such as a reactive element to a molten metal bath while resisting undesired oxidation. The injection apparatus consists of a body assembly having a chamber defined therein, and inlet and outlet passageways communicating with the chamber which cooperate to define a passageway therethrough. The lower end of the outlet extends below the surface of the molten metal bath. Purging gas is introduced through a gas inlet and provide a substantially purged atmosphere throughout the molten metal passageway. The atmosphere in the passageway is purged in order that the fluid material can be safely introduced into the molten bath.
