To provide a rotor for degasification capable of preventing the falling of a rotor from a shaft by increasing its durability, and further, to provide a rotor for degasification capable of suppressing production cost by simplifying a production process.SOLUTION: A rotor 11 for degasification is obtained by subjecting a granule-shaped refractory at least including graphite and ceramic to compression molding, in which a shaft 30 and a rotor 31 are formed so as to be inseparable. A gas passage 32 provided in the shaft and a gas diffusion passage 33 provided in the rotor are communicated, and an inert gas can be released from the periphery of the rotor into a molten metal.SELECTED DRAWING: Figure 3 【課題】耐久性を上げて、シャフトからロータが脱落することを防止することができる脱ガス用回転体を提供し、さらに製造工程を簡略化して製造コストを抑えるようにした脱ガス用回転体を提供する。【解決手段】脱ガス用回転体１１は、少なくとも黒鉛質とセラミックス質を含んだ粉粒体状の耐火物を圧縮成型してなり、シャフト３０とロータ３１が一体不可分となるように形成されている。シャフトが有するガス通路３２とロータが有するガス拡散路３３は連通しており、ロータ周縁から溶融金属内に不活性ガスを放出可能に形成されている。【選択図】図３
