Rotary Degassing Technology for Aluminum Alloys: Core Parameters and Quality Control
In aluminum casting production, melt quality directly determines the mechanical properties and defect rate of final castings. Rotary degassing injects inert gas through a high-speed rotating impeller to remove hydrogen and inclusions.
Core Parameters
- Rotational Speed: 300-500 rpm
- Gas Flow Rate: 5-15 L/min
- Treatment Time: 5-10 minutes per ton
- Immersion Depth: 2/3 of melt depth
