ABSTRACT:
An apparatus that gives continuous hydrogen heat treatment to anisotropic rare earth magnet powders is invented. The apparatus a comprises shopper 12, a furnace 11 to carry out a hydrogen heat treatment, a heat compensating means 14 that is placed in the heating room of the furnace to keep the treatment temperature constant, a movable stopper 15 to support the material in the heating room of the furnace 11 and a cooling container 18. The raw magnet powder is fed into the furnace 11 and supported by the stopper 15, then hydrogen heat treatment is carried out. After the treatment the stopper opens the bottom end of the heating room and the processed magnet powder falls into the cooling room. By the operation described above, the present apparatus can carry out continuous hydrogen heat treatment without stopping the heating of the furnace batch by batch. Continuous hydrogen heat treatment greatly improves the production efficiency and quality of the processed magnet powder.
