    摘要
  • 摘要: 用錳球團礦對鋼的直接合金化的動力學過程進行了研究,討論了初始鋼中碳、渣中MnO含量和渣的堿度及爐溫等與反應過程渣中MnO的還原速率的關系.MnO還原的表觀反應級數為一級.實驗得到錳的平均回收率為79.67%.

     

    Abstract: The kinetic process of direct alloying with manganese ore pellets in steelmaking has been studied. The relation of C in initial steel, MnO content in slag, the alkalinity of slag and furnace temperature with reducing rate of MnO in slag during reaction process has been analyzed. The apparent reaction order of MnO reduction is determined as first order reaction. The factors which influence the recovery of Mn and the end point Mn content has been also discussed. The average recovery of Mn is measured as 79.67%.
