| 简介 |
The rare earth sintered magnet manufacturing method of the present invention, rare earth sintered magnet for preparation of the rare earth magnetic powder; said rare earth magnetic powder a liquid solvent, and electric pumping of rare-earth magnetic powder form a slurry step; said rare earth magnetic powder slurry by clamping them with dies is filled with, said punch by said rare earth magnetic powder slurry by pressing the rare earth magnetic powder slurry liquid solvent magnetic rare earth by discharged into the outside of the mold for powder filling is formed, said rare earth magnetic powder for increasing availability of orientation of the rare earth magnetic powder having a density step for; the magnetic field said mold charge to pulsed magnetic is applied comprises at least one of said rare earth magnetic powder is for directing a beam, said rare earth magnetic powder in order to achieve a high rate orientation of 1 or more times said pulse magnetic field applying a plurality of times; said includes separating an RFID circuit comprises at least one of a light incoming from the entrance face and said; to sinter comprises at least one of said and including characterized in that step. |
