摘　　要：高性能粘结NdFeB磁体,由于其优异的磁性及可加工性,越来越受到市场的青睐。而我国企业却无法大规模生产高性能粘结磁粉,这制约了我国粘结磁体的健康发展。本文对国内传统快淬工艺与大规模连续快淬工艺生产粘结磁粉进行了分析比较,对连续快淬从配料、熔炼、快淬、晶化等各个方面进行了总结,也对生产实践的工艺和参数进行了探讨。The bonded NdFeB magnet, owing to its outstanding magnetic properties and machinability finds more and more applications. China, however, has made no great progress because NdFeB magnetic powder can not be produced in a large scale. This paper gives a comparison between domestic traditional and continuously melt-spun process. Moreover, We summarize the requirement for raw material, composition, smelting, melt-spinning and crystallizing. Finally, the production technological parameters are given.
