details


• Compared with graphite rotor, Silicon Nitride Ceramic will not be oxidized under high temperature environment, so it will not pollute the aluminum liquid, and the service life is much longer;

• The property of high thermal shock resistance ensures that the degassing rotor will not break during frequent intermittent operation;

• Because Silicon Nitride Ceramic is of high density and high strength, it assures that degassing rotor can be reliable and stable operation in high speed rotation.

Precautions for Use

• To ensure long-term stable operation of Silicon Nitride Ceramic Rotor, it is necessary to patiently adjust the concentricity of rotor shaft and transmission shaft during initial installation.

• For safety, the product shall be uniformly preheated above 400℃ before use. The rotor shall not be placed on the upper part of molten aluminum for heating, this action cannot achieve the effect of uniformly preheating the rotor shaft;

• In order to prolong the service life of the product, it is suggested to conduct surface cleaning and maintenance regularly (once every 12-15 days) and check the fastening flange bolts;

• When it is found that the rotor shaft has visible and obvious swing, it is necessary to stop the machine and readjust the concentricity of the rotor shaft to make it within a reasonable tolerance.
