Hydrogen Degassing Impeller and Shaft Introduction

Silicon nitride rotor is an appropriate product which could be used in depuration to dispose hydrogen of molten Aluminium. Silicon nitride rotor includes impeller and shaft.

Use of Silicon Nitride Rotor and Shaft for Aluminum Degassing

Silicon nitride degassing rotor for purification of aluminum melting.

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

Product Properties

1. Rotor and shaft are both made of silicon nitride 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.
