  degassing graphite rotor

  

Main products:

 

degassing graphite rotor, shaft , graphite crucibles,graphite moulds, graphite rods, graphite,graphite heater, graphite sets and so on.

 

Graphite rotor is an appropriate product which could be used in depuration to dispose hydrogen of Aluminium melt.
1. Application medium: Aluminium melt
2. Application temperature: ≤ 800degree celsius
3. Rotating Speed: ≤ 750 rotations per minute

 

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

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

Feature:

1. Thermal stability: According to the quench acute thermal using conditions of graphite crucible, we will specially design the production procedure, so as to ensure the reliability of product quality.
2. Corrosion resistance: Even and fine basic design will delay the erosion of crucible.
3. Impact resistance: Graphite crucible can bear high thermal impact, so any process can be carried out.
4. Acid resistance: The adding of special materials will greatly improve the quality of crucible, especially its index of acid resistance., and will prolong the service life of graphite crucible.
5. High heat Conduction: High content of fixed carbon ensures the good heat conduction, shorten the time of dissolution, and remarkably reduce the energy consumption.
6. Control of metal pollution: The component of material under strict control will ensure that graphite crucible will not pollute the metals when dissolving.
7. Quality stability: The process technology of forming under high pressure and quality guarantee system will fully ensure the stability of quality.
