About SiC Degassing Rotor
Made of our own SiC raw material, SiC degassing rotor are excellent to work in nonferrous metal casing, able to stand corrosion,anti-oxidation. It is widely applied in metal industry especially aluminum casting and aluminium purifying.
Application?
mainly used in nonferrous metal casting –aluminum casting, aluminium purifying.
Features?
1. Rotor and shaft are both made of silicon nitride bonded silicon carbide material, which shows advantage in anti-oxidation and anti-corrosion compared with graphite one. Within life span, degassing effect keeps stably good.
2. High-speed rotation can maximumly crush air bubble, and maximumly drive air bubble to cavity corner, improving degassing efficiency.
3. Rotor and shaft are anti-melting and anti-corrosion, no contamination to metal liquid.
4. It owns smooth surfacea and there will be no aluminum adhering or dreg accumulating. The concentricity is controlled within 1mm, which ensures smooth and peaceful rotation.
5. It cuts down the cost of degassing, such as inert gas consumption, grilled slag aluminum wastage, improving reliability of equipment and reduce cost of maintenance.
performance compared with other materials

High Quality of Raw Material
Smelted with pure petroleum coke, Hongyuan make SiC raw material by ourselves. We are the only one in China having complete SiC products chain:
SiC crystal smelting- SiC grains- SiC ceramic products
Advanced Equipments for Firing?
The automatic nitriding furnace in the largest volume, controlled by microcomputer, were honored the First Prize of China Machinery Industry Science and Technology Award for the residual-heat utilization system, meanwhile this nitriding furnace gaining state's utility patent.
