Jinyu Degassing Graphite Rotor and Shaft
More than 60 days of life
Good thermal stability
Competitve price
CE, ISO9001:2000

Graphite rotor revolves in high termperature, its peeled graphite floating the fusant surface to 

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

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 Shaft and Rotors have good performances of high mechanical intensity, superior resistant to molten iron scouring, resistant to sudden change in operating temperature, superior oxidation and corrosion resistance, this product is the main expendable parts for the air eliminating box during aluminum purification.

Working description of graphite rotors:

 The rotary rotor breaks the insufflated nitrogen (or argon) in the Aluminum fusant into numbers of dispersing bubbles, which are spreading in the metal liquid. As a result of gas partial pressure difference and surface absorption, the bubble absorbs the hydrogen and oxide and removes the gases out of the fusant as it rises, so as to purify the fusant. The bubble is small and dispersing, mixed well and twistly and slowly rises with the rotary fusant, keeps a long touch with the fusant, so the airflow will not arise and the purifying performance can be notably improved.
