| 简介 |
PROBLEM TO BE SOLVED : To provide a manufacturing method of a rare earth magnet capable of uniformly applying a powder of a rare earth compound over a sintered magnet body surface and further capable of extremely efficiently performing the application operation.
SOLUTION : A coating tank 1 including a net belt passage port 12 is prepared, and slurry with the rare earth compound powder being dispersed in a solvent is continuously supplied into the coating tank 1 and made overflow. A plurality of sintered magnet bodies 10 are arranged side by side on a net belt conveyer 5 and continuously conveyed in a horizontal direction, and pass the slurry in the coating tank 1 through the net belt passage port 12. After the slurry is applied to the sintered magnet body 10, the slurry is dried and the powder is continuously applied to the plurality of sintered magnet bodies 10.
