Title:
希土類磁石の製造方法及び希土類化合物の塗布装置
Document Type and Number:
Japanese Patent JP6369385
Kind Code:
B2
Abstract:
A coating tank 1 provided with a net belt passage opening is prepared, a slurry obtained by dispersing a rare-earth-compound powder in a solvent is continuously supplied to the coating tank 1 to cause the coating tank 1 to overflow, and a plurality of sintered magnet bodies 10 are arranged on a net belt conveyor 5, continuously conveyed horizontally thereon, and passed through the slurry in the coating tank 1 via the net belt passage opening, to apply the slurry to the sintered magnet bodies. The slurry is subsequently dried to continuously apply the powder to the plurality of sintered magnet bodies. As a result, the rare-earth-compound powder can be uniformly applied to the surfaces of the sintered magnet bodies, and the application operation can be performed extremely efficiently.
