Silicon Nitride Degassing Rotors (Si3N4) are used in metal casting industries for degassing operations, constructed of an excellent ceramic material known for its thermal and chemical resistance properties such as silicon nitride (Si3N4).

Silicon Nitride Ceramic will not oxidize under high temperature environments like that found in aluminum liquid, thus providing longer service life and protecting it from pollutant emissions; when compared with graphite rotors.

* Silicon Nitride Ceramic’s high thermal shock resistance guarantees that degassing rotor will remain intact during intermittent operations;* As it boasts superior density and strength properties, degassing rotor will be reliable and stable during high speed rotations.

*Precautions for Use* For optimal long-term operation of Silicon Nitride Ceramic Rotor, it is critical that initial setup involves meticulous adjustment of rotor shaft and transmission shaft concentricity to achieve long-term stable operation.

* To ensure product safety, products must be uniformly preheated above 400 degrees before use. Rotor should not be placed directly on molten aluminum for heating; such action cannot achieve uniform preheating of rotor shaft;

*To maximize the lifespan of the product, it is advised to perform surface cleaning and maintenance at regular intervals (once every 12-15 days) as well as inspect fastening flange bolts;

*When the rotor shaft exhibits visible and significant swing, it is essential that you stop the machine immediately and readjust its concentricity within an acceptable tolerance range.
