Abstract: A slurrying device includes a slurrying tank and a rotor stirrer. The rotor stirrer includes a stirring drum, a transmission gear arranged at an end face of the stirring drum configured to face the slurrying tank, and a rotor stirring rod configured to extend from the stirring drum and into the slurrying tank to stir a slurrying liquid in the slurrying tank. The rotor stirring rod is meshed with the transmission gear and configured to revolve along a planar trajectory of the transmission gear while simultaneously rotating. The rotor stirrer further includes a driving device provided at the stirring drum and configured to drive the rotor stirring rod to rotate via the transmission gear.

Abstract: A method for preparing semisolid slurry. The method is achieved using a device for preparing semisolid slurry. The device includes a slurry vessel and a mechanical stirring rod. The mechanical stirring rod includes a first end and a second end extending into the slurry vessel. The method includes: S1. putting a molten alloy having a first preset temperature into the slurry vessel; S2. cooling the molten alloy to a second preset temperature, positioning the second end of the mechanical stirring rod to be 5-25 mm higher than the bottom wall of the slurry vessel, rotating the mechanical stirring rod and injecting a cooling medium into the mechanical stirring rod; and S3: allowing the temperature of the molten alloy to be 10-90 degrees centigrade lower than the liquidus temperature of the molten alloy, stopping stirring and cooling, to yield a semisolid slurry.

Abstract: A die casting method includes stirring an aluminum alloy liquid in a stirrer under an airtight vacuum condition. The stirrer includes an electromagnetic inductor and a stirring rod. The aluminum alloy liquid is simultaneously subjected to an electromagnetic stirring in a direction of a magnetic field generated by the electromagnetic inductor and a mechanical stirring under a rotation action of the stirring rod. The aluminum alloy liquid is stirred for 20-80 minutes until the aluminum alloy liquid becomes semisolid to obtain a semisolid aluminum alloy slurry. The method further includes injecting the semisolid aluminum alloy slurry into a filter die to perform die casting molding at an injection speed of 1.5-2.5 m/s, an injection specific pressure of 30-80 MPa, a pressurization pressure of 60-80 MPa, and a temperature of the filter die of 250-400° C., and maintaining pressure for 7-30 seconds to obtain the filtering cavity.
