发明名称 METHOD FOR RECYCLING SLURRY, METHOD FOR MANUFACTURING RARE-EARTH BASED SINTERED MAGNET, AND APPARATUS FOR RECYCLING SLURRY
摘要 The present invention provides a producing method of a rare earth sintered magnet which is suitable as a producing method of a high performance rare earth sintered magnet which can reduce the number of steps for reusing defective molded bodies generated in a wet molding step of the rare earth sintered magnet, and which has a small content amount of oxygen. The invention also provides a slurry recycling method used for the producing method, and a slurry recycling apparatus. Each of the methods includes a crushing step of crushing, in mineral oil and/or synthetic fluid, a molded body in which slurry formed from alloy powder for a rare earth sintered magnet and mineral oil and/or synthetic fluid is wet molded in magnetic field, and recycling the crushed molded body into slurry.
