Box Type In-line Rotary Degassing Unit
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. As the gas floats, hydrogen and oxidized slags in the molten aluminium are brought to the surface, achieving degassing and refining.
The BDU Box Type In-line Rotor Degassing Unit features improvements in box sealing, spare parts service life, and anti-turbulence on the molten aluminium surface. These enhancements ensure safe, high-efficiency, continuous, stable, and low-cost operation.
Equipment Features
- Optimum dispersion of the process gas in the molten aluminium
- Maximum contact area and time between dispersing bubbles and molten aluminium
- Completely sealed box ensures stable inert gas environment
- Smooth molten aluminium surface without turbulent flow effect
- Easy installation and maintenance
- Simple replacement of pre-fired forming degassing box lining minimizes downtime
- Low maintenance and operation costs
- Long service life of heater and heater protection tubes
- Long service life of rotor and shaft
- Cooling gas without rotor rotating main shaft
