    • 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.

    • Alloy and cast alloy product ideally suited for use as a component in a vehicle frame or subframe, i.e., body-in-white, comprising an alloy consisting of about 2.00 to 5.00 wt. % magnesium, up to approximately 0.30 wt. % silicon, approximately 0.20 to 1.60 wt. % manganese, up to approximately 1.00 wt. % iron, and between about 0.10 to 0.30 wt. %, zirconium, the balance substantially aluminum and incidental elements and impurities. The aluminum/magnesium alloy is typically solidified into ingot derived working stock by continuous casting or semi-continuous casting into a shape suitable for remelt for casting, which shape is typically an ingot billet. Excellent mechanical properties are obtained from a cast product that is not subjected to high temperature heat treating operations subsequent to casting.

    • An improved casting nozzle for continuous slab casting machines is provided. The nozzle includes a sloped surface which reduces molten metal turbulence during the casting process. The nozzle also includes a resilient, thermal insulation layer which prevents undesired backflow and premature solidification of the molten metal near the nozzle tip. The nozzle may also include a friction reducing layer which prevents excessive wear or fracture of the nozzle as it contacts the casting mold. The casting nozzle is suitable for use with both horizontal and vertical continuous casting machines, and may be used with various types of casting molds including continuous belt or caterpillar molds, and stationary molds. The improved nozzle may be used to cast various metals such as aluminum and aluminum alloys.
