Introduction Si3N4 silicon nitride degassing rotor
Degassing rotor — Silicon Nitride ceramic rotor shaft exhibits exceptional wear and oxidation resistance compared to a graphite rotor. It assures stable high hydrogen removal efficiency for a long service life and it can reduce the frequency of replacing new parts, so that it can help customers save cost. The impeller structure design of rotor shaft helps the gas spreading evenly in the aluminum solution. At the same time, it reduce the gas into the solution and prevent the whirlpool shaped.
The high gas dispersibility makes hydrogen removal efficiency superior. Then it can improve the quality of die casting parts.
Characteristics Si3N4 silicon nitride degassing rotor
The efficiency of degassing is changeable according to the rotor shape and other condition.
We can design and produce the most suitable rotor according to customers’ environment.
