In order to remove the hydrogen in the aluminum liquid, nitrogen or argon is fed into the silicon nitride hollow rotor, and the dispersed gas is agitated at high speed to achieve the effect of neutralization and discharge of hydrogen.

Compared with graphite rotor, silicon nitride will not be oxidized in high temperature environment, so it will not pollute the molten aluminum, and the service life is longer;

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

The high temperature strength of silicon nitride ensures that the rotor runs smoothly at high speeds.
