Abstract：On the basis of the compositions of blast furnace (BF) slag at field, the desulphurization dynamics process was researched for BF slag with medium titanium and high alumina content, which was fabricated from pure chemical agents. The dynamics parameters of desulphurization were obtained. Results show that the sulfur content in liquid iron (w(［S］)) decreases with the elongation of desulphurization reaction time when the temperature is constant. Under the experimental conditions, the desulphurization process of BF slag with medium titanium and high alumina content belongs to second-order reaction, the restricted step of which is sulfur diffusion in the fused slag. The mass transfer coefficient (βS) rises with increasing the reaction, and the diffusion activation energy(ED) of sulfur element in fused slag is 127.03kJ/mol.
