An aluminum alloy material smelting device comprises a furnace and a packing device with a packing basket, a stirring shaft connected with the packing basket and a stirring head connected with the bottom of the packing basket. The stirring head comprises a plurality of stirring blades with one end connected with the bottom of the packing basket and another end connected with each other on the central axis of the packing basket. The side wall of the packing basket is provided with a liquid passage hole to exchange liquid with the solution outside the packing basket. By rotating the stirring head, a solution vortex accelerating the diffusion of added elements can be formed only under the stirring head, which will not damage the covering film formed on the surface of aluminum alloy. Thus the scum on the surface is effectively prevented from being involved in the solution again.

Aluminum alloy material smelting device

A high-strength A356 alloy and a preparation method thereof are disclosed. Modifiers Ba and Zr are added to improve the as-cast structure of the alloy. The high-pressure solidified A356 alloy prepared by a high-pressure solidification technology has finer grains, and the elements such as Mg and Si have higher supersaturated solubility in a matrix.
