Post combustion trials at Dofasco

NettetTraditional KOBM control methods included over- blowing the heat and maintaining a set hot metal Si/Mn ratio, are not effective in removing excess manganese. Analysis of manganese behavior in KOBM steelmaking showed that the reaction temperature and slag FeO content are the two major factors for the reaction under the KOBM … NettetThe new process control automation for the K-OBM converter must guarantee the safety conditions for bottom and side tuyeres to prevent overheating and/or infiltration of … lambertz kekse
