A coupled dynamic model is established to simulate the dynamic characteristic of vanadium extraction process in combined blown converter.The model consists of oxygen transfer model and slag-metal interfacial reaction model.The model canbe used to simulate the kinetic characteristics of hot metal containing low carbon and high vanadium.The simulation results show that the optimum addition of cold material is 50 kg/t at top blowing intensity of 2 m3/（min·t）.In this case,temperature of molten is 1 410 ℃ after 9 minutes’ smelting,and the content of vanadium in the molten iron is reduced from 1.2% to 0.04%.
