PURPOSE : A sintering apparatus for a magnetic anisotropy rare-earth permanent magnet is provided to sinter a molding product passed through a press process without contacting oxygen, cool the molding product quickly, and produce NdFeB magnet having an even particle size and approximately 500 ppm of a final oxygen content.CONSTITUTION : A sintering apparatus for a magnetic anisotropy rare-earth permanent magnet comprises : a sample charging apparatus(10), a vacuum chamber(20), and a furnace(30). The sample charging apparatus is able to block the outside air, and charges a molding product. The vacuum chamber is combined to be able to be separated from the sample charging apparatus, and keeps the charged molding product in a vacuumed state. The furnace is combined with the sample charging apparatus to be able to be separated, and heats the charged molding product.COPYRIGHT KIPO 2013
