SG-28 Silicon Nitride Ceramic Degassing Rotor

Compared with graphite rotors, SG-28 silicon nitride ceramic degassing rotor are al not oxidized in high-temperature status, so they do not pollute molten aluminum and have a longer service life. High density and high strength ensure reliable and stable operation during high-speed operation, with a speed of 600 rpm. The concentricity of the rotor is controlled within 0.2mm. The joints and flange connecting shafts are made of stainless steel. The processing accuracy can be within 0.01mm. With high-precision assembly, the stability of the aluminum liquid level can be maintained to an extent. It does not react with liquid aluminum and can maintain a good degassing effect for a long time.

Advantages And Features

1. Ultra-high speed, long life speed silicon nitride rotor
The rotor shaft and impeller are made of silicon nitride material, which has higher processing accuracy and material strength than graphite, so it can withstand higher speeds, up to 600 RPM. It does not react with liquid aluminum and can maintain a better degassing effect for a long time.

2. Concentric high-speed drive, liquid level float minimizes aluminum liquid level stability
The concentricity of the rotor is controlled within 20 wires, which can ensure the stability of the rotor at high speed. The rotor joint and flange connection shaft are made of stainless steel, the processing accuracy can reach less than 1 wire, and with high precision assembly, it can maintain the stability of the aluminum liquid surface to the extent.
