Hydrogen crushing device for rare earth magnetic material

一种氢粉碎装置是在为了进行稀土类磁性材料的氢粉碎处理的氢粉碎装置(10)中在所述炉主体(14)的开口部(16)前设置取出室(12)，并向其室内提供惰性气体。取出氢粉碎后的稀土类磁性材料，使输送设置(26)移动时磁性材料不接触大气。氢粉碎后的输送及冷却也在惰性气体中进行，防止高温状态的原料接触大气而氧化。有效率且安全进行稀土类磁性材料的氢粉碎处理工序及继续进行的冷却工序，可防止原料氧化，改善磁性。 A hydrogen pulverizer according to the present invention is an apparatus for subjecting a rare-earth...

The apparatus includes: a hermetically sealable hydrogen furnace, which includes a furnace body with an opening and a cap for closing the opening; a loading chamber for temporarily enclosing the rare-earth alloy magnetic material when the rare-earth alloy magnetic material, which has been pulverized with hydrogen, is unloaded from the furnace body through the opening; and an inert gas supply for supplying an inert gas into the loading chamber.
