The slag sampled during the multiple furnaces refining process has been analyzed , and then the thermo-dynamic calculation has been carried out , so as to find the effective method of desulfurization .The calculated results and the production practice indicated that when the current slag basicity R was in the range of 2.9 ~4.0, by strengthening the diffusive deoxidation , the sulfur in the steel could be removed effectively , as so to make sure that the sulfur content in the molten steel was equal to or less than 0.002%.Therefore, the requirements for smelting ultra low sulfur steel can be satisfied .
