| 简介 |
The present invention discloses a manufacturing method of green compacts of rare earth alloy magnetic powder and a manufacturing method of rare earth magnet, it is a manufacturing method that pressing the rare earth alloy magnetic powder added with organic additive in a closed space filled with inert gases to manufacture the green compacts, wherein the rare earth alloy magnetic powder is compacted under magnetic field in a temperature atmosphere of 25° C.-50° C. and a relative humidity atmosphere of 10%-40%. This method is to set the temperature of the inert atmosphere in a fully closed space, inhibiting bad forming phenomenon of the magnet with low oxygen content (broken, corner-breakage, crack) after sintering, and increasing the degree of orientation, Br and (BH)max. |
