摘　　要：氧化铁红(Fe2O3)是制造永磁铁氧体的主要原料,生产中一般采用水洗后再烘干的方法处理氧化铁红,但是处理后质量经常达不到工艺要求。本文对铁红处理进行了工艺改进,使用回转式干燥筒烘干的处理方法,使氧化铁红处理后达到生产工艺指标,并且对氧化铁红处理过程中排放的HCL气体进行了回收处理。Fe2O3 is the primary raw material of production the permanent ferrite magnets. In the course of produce, we deal with the raw material by the method of washing and drying, but its quality often does not meet technological requirements. In the paper,we improve the method and deal with Fe2O3 with the rotative drier. After deal with these raw material with the method, Fe2O3 reaches the produce technic indexes. And the HCl gas from drying is reclaimed.

关 键 词：氧化铁红 工艺改进 HCL气体
