CASTING MOLD WITH MULTI-FUNCTIONAL CHILL
20190240727 · 2019-08-08 ·

A casting mold with a multi-functional chill, a multi-functional chill, and a casting process facilitated by the multi-functional chill are disclosed herein. In addition to affecting the cooling rate of a casting inside the mold, the multi-functional chill may support and/or index the mold during handling and/or conveyance. The present invention allows for conveyance and/or handling of the mold or casting, with or without the mold, and allows for easy indexing and easy interaction with conveying and handling devices during and after heat treatment.

SHEAR INDUCED GRAIN REFINEMENT OF A CAST INGOT
20180243822 · 2018-08-30 · ·

Molten metal can be introduced into a liquid sump during direct chill (DC) casting, such as DC casting of aluminum, through a feed tube having a nozzle with an opening. The opening of the nozzle can be shaped and/or sized to generate a jet of molten metal within the liquid sump. The jet of molten metal can exhibit Reynolds number at or above a threshold amount. Such a jet can achieve improved metallurgical properties over standard casting techniques, such as improved grain refinement. A sufficiently high Reynolds number can be achieved by supplying the molten metal at a sufficiently high velocity. When supplying molten metal at a constant volumetric flow rate (e.g., to avoid fluctuations in casting speed), the nozzle can be crafted to have a smaller-than-standard diameter opening, thus generating a higher-than-standard velocity jet.
