Abstract
An apparatus for producing a metallic slurry material for use in semi-solid forming of a shaped part. The apparatus is generally comprised of a forming vessel and a thermal jacket. The forming vessel defines an inner volume for containing the metallic slurry material and has an outer surface. The thermal jacket has an inner surface disposed in thermal communication with the outer surface of the forming vessel to effectuate heat transfer therebetween. At least one of the forming vessel and the thermal jacket defines a number of grooves to limit the rate of heat transfer adjacent the grooves. In one embodiment, the forming vessel defines a plurality of axially-offset grooves extending about the entire periphery of the outer surface of the forming vessel. In another embodiment, a stator is disposed about the thermal jacket to impart an electromagnetic stirring force to the metallic slurry material contained within the forming vessel.
