本文论述了锰铁高炉中锰的还原机理,并结合生产实践数据,指出炉缸区不是锰还原的主要区域;锰在炉缸渣液面以上高温区已大量还原,MnO被CO还原是一个主要还原步骤;金属在滴落时趋向于炉子中心,基本不存在金属相中已还原的锰在燃烧带再氧化的问题。 In this paper, the reduction mechanism of manganese in ferromanganese blast furnace was discussed. According to the production practice data, it was pointed out that the hearth area was not the main area for manganese reduction. Manganese was largely reduced in the high temperature area above the slag level in the hearth, and the reduction of MnO by CO was a major Reduction step; the metal tends to the center of the furnace upon dripping, and there is substantially no problem that the reduced manganese in the metal phase is reoxidized in the combustion zone.
