It is necessary to reducing element carbon at the process of IF steel making. RH has become the most widely used refining equipment for decarburization because of its good effect. A mathematical model is created for circulate decarburization process of RH, considering the equilibrium of elements according to 210t RH for IF steel. The results imply that: the mathematical model is credible. The mass fraction of initial oxygen is required to exceed 0.06% to ensure the effect of decarburization when that of initial carbon is 0.03%. Also the rate of decarburization will increase by adding the lift gas flow. While the mostly significant impact on decarburization rate is the diameters of snorkel. The average mass fraction of carbon at the end of decarburization is about 0.0049% if the diameters of snorkel are 350mm. However that is only 0.0011% if the diameters of snorkel are 650mm.
