用锰球团矿对钢的直接合金化的动力学过程进行了研究，讨论了初始钢中碳、渣中MnO含量和渣的碱度及炉温等与反应过程渣中MnO的还原速率的关系．MnO还原的表观反应级数为一级．实验得到锰的平均回收率为79．67％．
The kinetics of the direct alloying of steel with manganese pellets was studied. The relationship between carbon and slag MnO content, alkalinity and furnace temperature in the initial steel and the reduction rate of MnO in the slag during the reaction was discussed . The apparent reaction order of MnO reduction is first order. The average recovery of manganese was 79.67%.
