Advantages of ceramic shaft and rotor for degassing in production of aluminum industry

1.Silicon Nitride ceramic rotor and shaft exhibit exceptional wear and oxidation resistance compared with the graphite rotor.

2.It assures stable high hydrogen removal efficiency for a long service life, and it can reduce the frequency of replacing new parts, so that help customer have good cost savings.

3.The impeller structure design of rotor shaft, help the gas spreading evenly in the aluminum solution, at the same time, reduce the gas into the solution, prevent the whirlpool shaped.
