新技术、新设备在NdFeB稀土磁体生产中的应用之五——烧结炉的改进

Application of New Technology & New Equipment in NdFeB Production Part 5: The Improvement of Sintering Furnace

中国磁材领域的研究人员和工程技术人员针对NdFeB磁体的特点,根据相关技术需求,已开发出一整套有自已特色的生产设备,能有效生产高档磁体。本文是关于NdFeB磁体生产新技术、新设备的系列报道,前文分别介绍了NdFeB磁体合金的制备新工艺—速凝薄片技术和设备、氢爆及气流磨(HD+JM)制粉、磁场取向成形工艺与设备、烧结工艺理论基础。本文是系列文章的第五篇,重点介绍多功能烧结设备。

Based on the unique characteristics of NdFeB materials and special technical requests of processing a series of producing equipment for magnet preparation has been developed by Chinese scientists and engineers. The new technology to prepare magnetic alloy-strip casting, powder preparing by HD ＋ JM, forming process by using press with high magnetic orientation field, and sintering technology have been introduced and discussed in previous papers, present paper is the fifth of this series, which introduces the improvement of multi-function sintering furnace.
