摘要： An apparatus for producing a thixotropic metallic melt by simultaneously controlledly cooling and stirring the melt to form solid particles of a first phase suspended in a residual liquid second phase. Vigorous stirring of the metallic melt results in the formation of degenerate dendritic particles having substantially spheroidal shapes. The metallic melt is stirred to rapidly and efficiently circulate the forming semi-solid slurry. Circulation of the forming semi-solid slurry results in a substantially uniform temperature throughout. Through precision stirring and cooling, a semi-solid slurry is formed having a first solid phase of about 70–80 wt. % suspended in a second liquid phase.

摘要： 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.

摘要： A container system including a vessel for holding a thixotropic semi-solid aluminum alloy slurry during its processing as a billet and an ejection system for cleanly discharging the processed thixotropic semi-solid aluminum billet. The crucible is preferably formed from a chemically and thermally stable material. The crucible defines a mixing volume. The crucible ejection mechanism may include a movable bottom portion mounted on a piston or may include a solenoid coil for inducing an electromotive force in the electrically conducting billet for urging it from the crucible. During processing, a molten aluminum alloy precursor is transferred into the crucible and vigorously stirred and controlledly cooled to form a thixotropic semi-solid billet. Once the billet is formed, the ejection mechanism is activated to discharge the billet, from the crucible. The billet is discharged onto a shot sleeve and immediately placed in a mold and molded into a desired form.

摘要： A method of producing on-demand, semi-solid material for a casting process includes the steps of first heating a metal alloy until it reaches a molten state and maintaining that molten state within a desired temperature range. The next step is to ladle out a portion of the molten alloy and transfer it into a processing vessel. In one arrangement the vessel is configured with its own cooling arrangement so as to begin the solidification process for the molten alloy. In another embodiment, a thermal jacket is used to facilitate the cooling of the vessel and accordingly the cooling of the molten alloy. The next step is to apply an electromagnetic field to the molten alloy in order to create a stirring action which results in a desired flow pattern of the molten alloy within the vessel. The electromagnetic stirring begins as soon as the molten alloy is placed in the vessel and continues while the cooling continues in order to create a slurry billet of the desired metallurgical composition. The final step is to discharge the slurry billet from the vessel directly into a shot sleeve of a casting machine. The apparatus related to the described method includes a vessel which is constructed and arranged for receipt of the molten alloy. A robotic arm is provided in one embodiment for moving the vessel into a stator and then from the stator to the discharge location. In another embodiment, pneumatic cylinders are used in cooperation with structural linkages to effect movement of the vessel first into the stator and then from the stator to the discharge location. Suitable cooling arrangements for the vessel include cooling lines within the vessel, the passage of cooling air between the stator and the vessel, and the use of a thermal jacket.

摘要： An apparatus for and method of controlling the cooling rate of a metallic melt in the production of a semi-solid slurry billet for use in a casting process. The apparatus comprises a thermal jacket including symmetrical halves, with each half having a rounded heat transfer surface extending between a pair of longitudinal edges. An actuator mechanism engages the heat transfer surfaces into intimate contact with a vessel containing the metallic melt to effectuate conductive heat transfer between the vessel and the thermal jacket, with the pairs of longitudinal edges of each halve being disposed in a generally opposite, spaced relationship. The thermal jacket includes a plurality of passageways adapted to carry cooling air for extracting heat from the metallic melt, and a plurality of electric heating elements for adding heat to the metallic melt. The cooling rate of the metallic melt is controlled within a range of about 0.1 degrees Celsius per second to about 10 degrees Celsius per second by regulating the flow of cooling air through the passageways and by regulating activation of the heating elements. The thermal jacket includes fluid manifolds disposed at opposite ends of the thermal jacket to distribute and direct the flow of cooling air, and a plurality of exhaust ports extending between each of the passageways to an exterior surface of the thermal jacket to discharge heat laden cooling air in a lateral direction.
