In the aluminum melting and processing industry, product quality and production efficiency are always the core concerns of enterprises. With the increasing demand for high-quality aluminum, the purity of liquid aluminum becomes particularly important. Gases and impurities in liquid aluminum can affect product performance, resulting in production defects and waste.

As one of the most effective molten aluminum degassing technologies, the box degassing device efficiently removes gases and inclusions from liquid aluminum, making it the preferred solution for high-end aluminum castings.

In a box type degassing device, the rotor rotates at high speed in the box to disperse the inert gas to form a large number of small dispersed bubbles. These small bubbles enter the aluminum liquid, and carry away the hydrogen and oxidation slag in the aluminum liquid with the floating, to achieve the purpose of degassing and refining. During the rise of the bubble, the inclusions will be brought out of the surface of the liquid aluminum by surface tension to form scum, so as to effectively remove impurities. At the same time, the stirring of the rotor makes the alloy composition in the aluminum liquid more uniform, and further improves the quality of the aluminum liquid. Through this process, the box degassing unit significantly improves the purity and performance of the aluminum.
