Method and device for preparing semi-solid slurry

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.
