In addition to the general properties of aluminum, due to the different types and amounts of alloying elements added, aluminum alloys also have some specific properties of alloys. The density of aluminum alloys is 2.63 - 2.85 g / cm3, with relatively high strength (σb is 110 - 650 MPa), specific strength close to high alloy steel, specific stiffness exceeding that of steel, good casting performance and plastic processing performance, good electrical and thermal conductivity, good corrosion resistance and weldability, and can be used as structural materials, with wide applications in aerospace, aviation, transportation, construction, electromechanics, light chemical industry and daily necessities.

[0003] Aluminum alloy casting and rolling is a process of directly "casting and rolling" molten metal into semi-finished billets or finished products. When degassing aluminum alloy casting and rolling production, a stirring device will be used. However, there are still some drawbacks in the existing degassing and stirring devices for aluminum alloy casting and rolling production during use. It is not convenient to separate bubbles from the metal melt, resulting in the easy appearance of pores inside the aluminum alloy, greatly reducing the quality of the aluminum alloy. For this reason, we propose a degassing and stirring device for aluminum alloy casting and rolling production to solve the above problems. Content of the Utility Model
