In order to remove the hydrogen in the aluminum liquid, a hollow silicon nitride rotor is used to feed nitrogen or argon, and the dispersed gas is stirred at a high speed to achieve the neutralization and discharge of hydrogen.

Advantage:

• Compared with graphite rotors, silicon nitride will not be oxidized in high temperature environments, so it will not pollute the aluminum liquid and has a longer service life;

• High thermal shock resistance ensures that the rotor will not break during frequent intermittent operation;

• The high-temperature strength of silicon nitride is high, which ensures that the rotor runs smoothly at high speeds.
