摘要： A method and apparatus for stirring a molten thixotropic aluminum alloy comprising a first solid particulate phase suspended in a second liquid phase so as to maintain its thixotropic character by degenerating forming dendritic particles into spheroidal particles while simultaneously equilibrating the melt temperature by quickly transferring heat between the melt and its surroundings. The melt is stirred by a magnetomotive force field generated by a stacked stator assembly. The stacked stator assembly includes a stator ring adapted to generate a linear/longitudinal magnetic field positioned between two stator rings adapted to generate a rotational magnetic field. The stacked stator rings generate a substantially spiral magnetomotive mixing force and define a substantially cylindrical mixing region therein.

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： 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 (such as graphite or a ceramic). 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.
