Advantage of Silicon Nitride Degassing Impeller and Shaft

1.Si3N4 degassing shaft and rotor is mainly working in molten aluminum, it has very long lifespan, more than ten times than similar graphite shaft and rotors.

2,Now more and more plants use it instead of graphite products to reduce the production cost.

Heat Resistant Silicon Nitride Ceramic Shaft And Rotor For Degassing Use

Si3N4 material is suitable for molten aluminum liquid degassing pipe and rotor.
In order to remove hydrogen from molten aluminum, a silicon nitride pipe is used to feed nitrogen or argon, while silicon nitride rotor is used to stir up and disperse the gas bubble, and then take the Nitrogen out with the bubble throughout the molten bath, thus get the result of hydrogen remove.
