摘要：【中文】本发明涉及一种钕铁硼磁粉的制备方法，其属于钕铁硼磁体制作方法技术领域。包括如下工艺步骤：将钕铁硼薄带合金放入氢处理炉中，氩气气氛下升温至390℃~480℃后，通入氢气，维持氢气压力0.15Mpa~0.20Mpa进行吸氢。之后停止加热开始降温，温度降至220℃或以下时，用氩气置换氢气。待降至室温后再升温至550℃抽真空脱氢5小时，再使用气流磨对氢处理后的合金进行磨粉。本发明通过控制吸氢反应的温度，将富钕相和主相的氢破碎过程分开进行，使得氢破碎更彻底和均匀，气流磨磨粉过程中磨粉效率更高，粒度分布更窄，磁粉收率更高。提高了原材利用率，并为磁体性能的提高奠定了基础。 【EN】The invention relates to a preparation method of neodymium iron boron magnetic powder, and belongs to the technical field of manufacturing methods of neodymium iron boron magnets. The method comprises the following process steps: and (3) putting the neodymium iron boron thin strip alloy into a hydrogen treatment furnace, heating to 390-480 ℃ under an argon atmosphere, introducing hydrogen, and maintaining the hydrogen pressure of 0.15-0.20 Mpa to absorb hydrogen. Then, the heating was stopped and the temperature was lowered to 220 ℃ or below, and then the hydrogen gas was replaced with argon gas. After the temperature is reduced to the room temperature, the temperature is raised to 550 ℃, the vacuum pumping and the dehydrogenation are carried out for 5 hours, and then the alloy after the hydrogen treatment is milled by using an air flow mill.
