Degasification stick

The utility model relates to a degasification stick, including graphite degasification stick body, the mesopore that is used for letting in the argon gas is offered in the centre of graphite degasification stick body to the degasification rotor link of lower extreme for being used for connecting the degasification rotor of graphite degasification stick body, the characteristic is: ceramic protection tube is established to the cover on the graphite degasification stick body. Pottery protection tube and graphite degasification stick body in close contact with. The lower extreme of pottery protection tube sets up the graphite sheath, and the graphite sheath passes through threaded connection with graphite degasification stick body. Expose in the aluminum alloy liquid surface upper end of graphite degasification stick body. The aluminum alloy liquid surface is exposed to the upper end of pottery protection tube, and the lower extreme of ceramic protection tube is located below the aluminum alloy liquid liquid lev
