To remove H2 gas from molten aluminum, a silicon nitride pipe is used to feed the N2 or Ar gas. As silicon nitride rotor is used to stir and disperse the gas throughout the molten aluminum bath.
■ Unlike graphite,the silicon nitride is hardly eroded by oxygen at elevated temperatures. This permits long operating life.
■ High density and high strength assure reliable and stable operation in high speed rotation.
■ High thermal shock resistance allows repeated insertion and withdrawal from molten aluminum in batch operation.
■ Strong corrosion resistance and good corrosion resistance, no pollution to molten aluminum, help to improve the quality of molten aluminum, to ensure high processing accuracy and tightness.
■ Non-adhesive aluminum, no accumulation of aluminum slag, improve the reliability of equipment, reduce equipment maintenance costs.
■ The degassing efficiency varies greatly depending on the shape of the rotor and other conditions, so we can offer you the right solution for the application environment.
