Rotary Degassing Unit
Complete rotary degasser: drive, shaft, rotor, anti-vortex plate, gas panel and frame
Overview
What it is and where it works
A complete rotary degassing unit (drive, lifting frame, shaft, rotor, anti-vortex plate and gas control panel) that injects nitrogen or argon through a spinning rotor to remove dissolved hydrogen from the melt. The rotor breaks the gas into fine bubbles that collect hydrogen as they rise. Used in ladles or holding furnaces before casting to reduce gas porosity. Flux and gas injection is part of the standard offer.
- Purge gas
- Nitrogen most common for cost; argon as alternative
- Process variables
- Rotor speed, gas flow and treatment time set the result
- Ladle rotors
- Typically 175 to 220 mm diameter for batch ladle treatment
In your plant
Where It Is Used
- Batch degassing in transfer ladles
- Degassing in holding furnaces before casting
- Die casting and gravity casting where porosity causes scrap
- Combined with flux injection for inclusion removal

Frequently Asked Questions
Nitrogen or argon?
Both are used; nitrogen is the most common because it costs less. The choice depends on your alloy and quality targets.
How long does a graphite rotor last?
Graphite rotors wear and are replaced regularly; one published source gives a life of one to four weeks depending on use. We can quote spare rotors and shafts with the unit.
