Advantage of Aluminum degassing anti-oxidation graphite rotor
Silicon nitride degassing rotor for purification of aluminum melting.Silicon nitride rotor includes impeller and shaft.
Used in the aluminum and zinc casting industries, nitrogen, argon or carbon tetrachloride are injected and sprayed into molten metal through silicon nitride rotors for dehydrogenation. It can eliminate the bubbles inside the castings and improve their inner quality. Injects inert gases into the Metallic solution.Silicon nitride rotor is an appropriate product which could be used in depuration to dispose hydrogen of molten Aluminum.
