A kinetic model, which considers the effect of transitory reaction and permanent-contact reaction on sulfur removal rate, as in the case of using CaO-CaF2 based fluxes powder injection to desulfurize hot metal containing vanadium of 0.34% and sulfur content of 0.08% is developed in the present work. Some important factors affecting kinetics of desulfurization, such as the transitory reaction parameter E, rate constant for permanent contact reaction K, can be determined by means of experimental and industrial practice results, respectively. The influence of E and K on sulfur content in hot metal is discussed. The model will be available for predicting the variation of sulfur content in hot metal and will contribute to control automatically for the desulfurization process.
