Applied Effects of Different Hot Metal Desulfurizing Processes

LIU Bingyu (Technical Department, Wuhan Iron and Steel Group Co.,Wuhan 430083)  
Basic conditions of advancing hot metal pretreatment capability in WISCO measures for optimizing processes of kinetics rabbling, injecting in torpedo ladle and hot metal ladle, and results of depressing production cost are reported.The test results of CaO, CaC 2, CaO+Mg, pure Mg different desulfurizing agents compared with new desulfurizing one in these processes are discussed.Kinetics rabbling has good dynamic conditions.Weak desulfurizing agents is used and deep desulfurization is realized in kinetics rabbling.Injecting in torpedo ladle is applied to hot metal pretreatment with large quantity of hot metal.But the dynamic conditions of injecting in torpedo is not good.The desulfurizing agents consumption of injecting in hot metal ladle is low.It has stable injecting process and short treatment time.
