In the molten aluminum degassing device, inert gases such as nitrogen and argon are blown into the aluminum liquid, impurities float, and a large amount of hydrogen is dehydrogenated, which can greatly improve the quality of aluminum alloy.<\/p>\n

Using an aluminum degassing device<\/a>, the bubbles have no dead ends, but are small and large. Rolling up and down, the temperature of the molten aluminum is uniform, the alloy performance is greatly improved, and good economic benefits have been achieved. The degassing box has a simple structure and does not pollute the molten aluminum. It has the characteristics of low cost, long life and easy maintenance. It is widely used in the casting of automotive aluminum parts.<\/p>\n

\"Molten<\/p>\n

Molten aluminum degassing device mainly treats molten aluminum containing a certain amount of hydrogen and other residues (alkali metals, inclusions), and removes it after treatment by a mobile degassing device.<\/p>\n

The treatment principle is the air flotation principle. The process gas (inert gas or a mixture of inert gas and chlorine) is injected into the melt through the rotor, and the rotor is broken into uniformly dispersed micro-bubbles, which rise to the surface of the melt.<\/p>\n

In the process of microbubbles ascending, the following work has been completed:<\/p>\n
