| titleOfInvention | Method and apparatus for manufacturing magnetic anisotropic rare earth sintered magnet |
| abstract | In order to improve the performance of the rare earth magnet, it is effective to reduce the oxidation of the powder and to reduce the particle size of the powder. SUMMARY OF THE INVENTION An object of the present invention is to provide a method for producing a magnetic anisotropic rare earth sintered magnet which can safely use an extremely active powder having a low degree of oxidation and a small powder particle diameter, and efficiently producing various shapes of products. Is to provide a way to do this.n n n In the weighing and filling section 41 and the densifying section 42, a fine powder, which is a raw material of the magnetic anisotropic rare earth sintered magnet, is filled into a mold so as to have a predetermined density, and the magnetic field orientation section 43 After the fine powder is oriented by the pulse magnetic field, the fine powder is sintered in the sintering furnace 44 without pressing the fine powder. In this method, the mass production apparatus is simple in operation, and the enclosure can be made small. Therefore, it is possible to eliminate the risk of oxidation or combustion of powder, which has been a problem in the conventional method using a large-scale press apparatus. . In addition, it is possible to efficiently produce a plurality of products of the most important shape of rare earth sintered magnets, such as flat plate and arch plate magnets, by using a mold. |
