Embodiment Construction
[0040] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.
[0041] Such as Figure 1 to Figure 9 As shown, it is a semi-solid rapid pulping method of aluminum alloy involved in the present invention, which includes putting the aluminum alloy melt 11 in the container 1, and the stirring head 2 protruding into the liquid level of the aluminum alloy melt 11 in the container 1 and rotate around the axis of the stirring head 2 to stir the aluminum alloy melt 11; the stirring head 2 is formed with a cooling channel, and the cooling channel is at least partly located below the liquid level of the aluminum alloy melt 11, The upper part of the stirring head 2 has a cooling inlet 22 and a cooling outlet 23 communicating with the cooling channel; during the rotation of the stirring head 2, the cooling medium flows in the cooling channel and exchanges heat with the aluminum alloy m...

The invention discloses an aluminum alloy semi-solid rapid pulping method which comprises the following steps: an aluminum alloy melt is contained in a container, and a stirring head extends below the liquid level of the aluminum alloy melt in the container and rotates around the axis of the stirring head so as to stir the aluminum alloy melt; a cooling flow channel is formed in the stirring head, at least part of the cooling flow channel is located below the liquid level of the aluminum alloy melt, and a cooling inlet and a cooling outlet communicating with the cooling flow channel are formed in the upper portion of the stirring head; in the rotating process of the stirring head, the cooling medium flows in the cooling flow channel and exchanges heat with the aluminum alloy melt so as to reduce the temperature of the aluminum alloy melt, and fluid in the cooling flow channel does not make direct contact with the aluminum alloy melt in the heat exchange process. Compared with the prior art, the stirring head has the advantages that the cooling runner is arranged in the rotating shaft, so that when the stirring head stirs an aluminum alloy melt to generate shearing force, fluid flows through the cooling runner in the stirring head for heat exchange, generation of dendritic crystals is promoted, and the pulping process is quicker.
Description
technical field [0001] The invention relates to the technical field of aluminum alloy pulping, in particular to an aluminum alloy semi-solid fast pulping method. Background technique [0002] Semi-solid forming technology refers to certain technical treatments (such as mechanical stirring, adding grain refiners, etc.) to the metal in the solidification process to change the nucleation and growth modes of the primary solid phase or to fully break the formation dendrites, a semi-solid slurry containing a nearly spherical or roseate primary solid phase was obtained. [0003] When preparing slurry, the shear force generated by stirring is used to fully break and free the dendrites formed during the solidification process, so that a large number of fine grains formed are evenly distributed in the molten metal. The stirring-based pulping method mainly includes mechanical stirring Method, electromagnetic stirring method and later ultrasonic vibration method, gas stirring method, a...
