Degassing Equipment is an essential molten aluminum treatment system designed to remove dissolved hydrogen and reduce non-metallic inclusions before casting. By improving molten aluminum cleanliness, the system helps reduce gas porosity, pinholes, leakage defects, and other casting quality problems.
The equipment adopts rotary degassing technology, using a rotating graphite rotor to disperse inert gas into fine bubbles inside molten aluminum. These bubbles absorb dissolved hydrogen and help float inclusions to the aluminum surface for removal.
It is widely used in aluminum billet casting, slab casting, foundry applications, recycled aluminum treatment, and high-quality wrought alloy production lines.
Tilting and Drain-back Device (Optional)
Advantages
1. Reduced Residual Aluminum Loss
The tilting and drain-back mechanism pours residual aluminum from the casting chamber into the launder and then into the casting machine, helping eliminate residual aluminum while reducing remelting and manual labor costs.
2. Improved Leakage Prevention
The system solves the aluminum leakage problem in rotary launders by using imported graphite gaskets with a service life of up to 6 months.
3. Easy Cleaning and Maintenance
The rotary launder has an inner diameter of 240 mm. Its lining is integrally formed by firing and assembled with the outer shell, making cleaning and replacement easier.
4. Higher Automation Level
The tilting mechanism adopts a proportional valve hydraulic control system and can be linked with the casting machine for highly automated operation.
