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.
Equipment Features
● Optimum dispersion of the process gas in the molten aluminium
● The max. touch area and time between the dispersing bubbles and
the molten aluminium
● The box is completely sealed to ensure a stable inert gas
environment
● The molten aluminium surface is smooth without turbulent flow
effect
● Easy for Installation & Maintenance
● Simple replacement of the inner lining of the pre-fired forming
degassing box minimizes production downtime
● Low Maintenance & Operatrion Cost
● Long service life of heater and heater protection tubes
● Long service life of rotor and shaft
● Cooling gas without rotor rotating main shaft
