Box Type In-line Rotory Degassing Unit
Hydeb BDU Box Type In-line Rotor Degassing Unit is usually installed between the discharge outlet of the smelting furnace and the filter box. The Molten Aluminium flows into the box of the degassing unit and flows out from the outlet of the degassing unit, that is, realizing the purpose of continuous In-line refining.

Hydrogen Removal·Impurity Removal·Alkali Removal

One Of The Most Effective Degassing Technologies For Molten Aluminium. The First Choice For High-End Aluminium Castings.

The rotor is rotated in the box to break the inert gas, forming a large number of dispersed bubbles into the molten aluminium, and with the gas floating, the hydrogen and oxidized slaggs in the molten aluminium will be brought out from the molten aluminium surface to achieve the purpose of degassing and refining.

The BDU Box Type In-line Rotor Degassing Unit has been improved in many key points such as the box sealing, spare parts service life, and anti-turbulence on the surface of molten aluminium and so on, which will be ensuring the safe, high-efficiency, continuous and stable, and low-cost operation of the degassing device.
