A rare-earth
alloy permanent
magnet material preparation device comprises a
raw material treatment portion, a
precipitation tank, an electrolytic furnace, a
grinding mechanism, a
stamping mechanism and a
vacuum sintering furnace. The
raw material treatment portion comprises a rare-earth
metal treatment tank and a blending tank, a delivery
pipe connected with the blending tank is arranged on the rear-earth
metal treatment tank, the blending tank is connected with the
precipitation tank through a complexing solution delivery
pipe, the
precipitation tank is connected with the electrolytic furnace, a feed inlet is arranged on one side of the electrolytic furnace, a
casting chamber is arranged at the
tail end of the electrolytic furnace and connected with a
cooling chamber, the
cooling chamber is connected with the
grinding mechanism through a
discharge pipe, and the
grinding mechanism is connected with the
stamping mechanism which is connected with the
vacuum sintering furnace. The problem of segregation of
alloy ingots is solved effectively, high temperature strength,
structural stability,
welding performance and
corrosion resistance of the
alloy ingots are improved beneficially due to addition of Sc, and the common electrolytic furnace can be used for
smelting the alloy ingots by adopting mixture after Nd, Pr, Dy and Sc complexing.
