METHOD FOR PRODUCING RARE-EARTH MAGNETS, AND RARE-EARTH-COMPOUND APPLICATION DEVICE

Title:

METHOD FOR PRODUCING RARE-EARTH MAGNETS, AND RARE-EARTH-COMPOUND APPLICATION DEVICE

Document Type and Number:

WIPO Patent Application WO/2016/175063

Kind Code:

A1

Abstract:

A fixed beam 2 along which magnet-body holding sections 22 are consecutively provided is disposed so as to pass through a slurry 1. Sintered magnet bodies m placed in the magnet-body holding sections 22 by movable beams 3 are conveyed by repeating an operation in which the sintered magnet bodies m are moved to the following magnet-body holding sections 22. While being conveyed, the sintered magnet bodies m are passed through the slurry 1 to apply the slurry thereto, and are subsequently dried to remove a solvent in the slurry and affix a powder in the slurry thereto, and, as a result, the powder is continuously applied to the plurality of sintered magnet bodies. Accordingly, a rare-earth-compound powder can be uniformly applied to the surfaces of the sintered magnet bodies, and the amount of the slurry taken from a coating tank can be reduced to effectively decrease wasteful consumption.
