Graphite rotors, impellers and shafts for aluminum gas injections systems

1. Excellent oxidation resistance

2. Rotor designed for good gas dispersal

3. vane rotor to reduce bubble size for better hydrogen removal

4. Efficient removal of hydrogen and unwanted particles

5. One piece construction

6. Applications

In the aluminum and zinc casting industries, nitrogen, argon or carbon tetrachloride are injected and sprayed into molten metal through graphite rotors for dehydrogenation. It can eliminate the bubbles inside the castings and improve their inner quality.  Injects inert gases into the Metallic solution

7. Programmable properties

- Machined with high quality graphite billet.

- Treated with THREE TIMES special oxidization retardent process to prolong their operating life.

 

8. cTypical sizes

 

- Graphite rotor rod :   Diameter: 50 - 150mm     Length: 500 - 1200mm

- Graphite rotor head:  Diameter: 100 - 300mm

- Or as per the customers' requirement.

 

 

 

Graphite rotor is an appropriate product which could be used in depuration to dispose hydrogen of Aluminium melt.
