发明名称 Continuous hydrogen pulverization method and production device of rare earth permanent magnetic alloy
摘要 A continuous hydrogen pulverization method of a rare earth permanent magnetic alloy includes: providing a hydrogen adsorption room, a heating dehydrogenation room and a cooling room in series, applying hydrogen adsorption, heating dehydrogenation and cooling on a rare earth permanent magnetic alloy in the production device at the same time, wherein collecting and storing under an inert protection atmosphere can also be provided. Continuous production is provided under vacuum and the inert protection atmosphere in such a manner that an oxygen content of the pulverized powder is low and a proportion of single crystal in the powder is high.
