In the degassing unit, the hydrogen content of the molten aluminum—initially 0.25–0.30 cc/100 g—is reduced to 0.15–0.20 cc/100 g.
A 3–5% chlorine (Cl₂) gas mixture is available as an option for the removal of alkali impurities such as sodium (Na), potassium (K), and lithium (Li).
Capacity: 35 tons/hour
Process gas: Ar, N₂ (optional Cl₂)
Gas injection: Via 1 graphite rotor
The degassing unit consists of the following components:
- Crucible with a 650 kg molten aluminum capacity
- 1 graphite rotor (mounted on the lid)
- Pneumatic rotor lifting system
- Gas mixing panel (N₂/Ar + optional Cl₂)
- Crucible inlet and outlet rails/slides
- Control panel (ABB)
