Problems solved by technology

[0003] At present, the commonly used methods for preparing metal semi-solid rheological forming slurry mainly include mechanical stirring method, electromagnetic stirring method, double helix stirring method, vibration method, single roller rotation method, inclined cooling plate method, rotating conveying pipe method, etc. Most of these technologies use external power to stir the slurry during the slurry preparation process. Stirring requires an external power device, which consumes a lot of energy. At the same time, stirring is easy to introduce external impurities, which will cause new pollution to the slurry; In addition, in the prior art, most of the methods in the process of preparing semi-solid slurry, the slurry is in contact with the air, the high-temperature slurry is easy to oxidize with the oxygen in the air, and the impurities in the air are also easy to adhere to the slurry , the more important thing is that the slurry moves violently during the stirring process, and the phenomenon of "air entrainment" is prone to occur, which seriously affects the quality of slurry preparation; therefore, how to ensure the cleanliness of the metal slurry and how to save the slurry during the slurry preparation process The energy consumption in the process of material preparation and how to improve the quality of the slurry have an important impact on the effect of semi-solid slurry preparation, which is the key to whether the semi-solid can achieve industrialization
