Silicon nitride degassing rotor for purification of aluminum melting melts
For the removal of hydrogen in molten aluminum, silicon nitride tubes are used to put into nitrogen or argon.Silicon nitride rotors are used in the whole process of molten aluminum to stir and disperse gas.Compared with graphite rotor, the service life of silicon nitride rotor is longer because no oxygen corrosion when heating up.With the characteristic of high density and high strength, silicon nitride rotor makes the running table when high speed rotating.With high thermal shock resistance performance, it can be inserted in and pulled out from molten aluminum repeatedly in batch operation.
Product characteristics:
2.The design of high rotating speed can break the bubbles to the maximum extent and disperse the bubbles to all corners of the inner chamber to improve the degassing efficiency;
4.The surface is smooth, free of aluminum and slag. At the same time, the manufacturing accuracy of the complete degassing rotor is high, and the concentricity is controlled within 1mm to ensure the stability of rotor operation at high speed, and minimize the disturbance to the melt surface, thus reducing the fluctuation of liquid level;
