Fine grain casting by mechanical stirring |
摘要 |
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.
