Title:
THERMAL JACKET FOR A VESSEL
Document Type and Number:
WIPO Patent Application WO2001091944
Kind Code:
A9
Abstract:
A thermal jacket (30) for use in the production of a semi-solid slurry billet. The thermal jacket (30) includes symmetrical halves (30a, 30b), each having a heat transfer surface (50) extending between a pair of longitudinal edges (54a, 54b). An actuator mechanism (32) engages the heat transfer surfaces (50) into intimate contact with a vessel (20) containing metallic melt to effectuate conductive heat transfer, with the longitudinal edges (54a, 54b) being disposed in a generally opposite, spaced relationship. The thermal jacket (30) includes a plurality of cooling air passageways (120, 122) for extracting heat from the metallic melt, and a plurality of electric heating elements (132) for adding heat to the metallic melt. The cooling rate of the metallic melt is controlled within a range of about 0.1 to 10 degrees Celsius/second by regulating the flow of cooling air and the activation of the heating elements (132). Fluid manifolds (104, 106) are disposed at opposite ends of the thermal jacket (30) to distribute and direct the flow of cooling air.
