摘　　要：探讨了粘结磁粉生产过程中氯对生产设备、厂房的影响,原料中高氯铁红破坏作用明显,不容忽视。分析了氯对混料、配料的影响,影响原料的成份一致性,配比的准确性;影响原料的水分含量,造成结团混料不均匀。通过形貌分析、性能测定,氯含量高对预烧料烧结不明显,六角片状程度低,粒径不均匀,原料经处理后氯含量降低,烧结完全,六角片状程度高,粒径均匀;性能测定得到氯含量高造成产品磁性能较低,压制厚度高,不容易与高分子结合。The influence of chlorine on production equipment and plant in the production process of bonded magnetic powder was discussed. The damage effect of high-chlorine iron red in raw material was obvious and could not be neglected. The effects of chlorine on the mixing and dosing were analyzed, and the consistency of the raw materials was affected. The accuracy of the ratio was affected. The moisture content of the raw materials was affected, and the agglomeration of the agglomerates was not uniform. Through the analysis of morphology, the determination of performance, the high content of chlorine is not obvious for the sintering of the calcined material, the hexagonal sheet is low, the particle size is not uniform, the raw material is reduced after the treatment, the sintering is complete, the hexagonal sheet is high and the particle size is uniform; Performance determination of high chlorine content caused by low magnetic properties, high thickness of the press, not easy to combine with the polymer.
