The reaction rate were measured for the desulphurization of molten Fe-C-S alloys with oxygen gas by flow method. As the rates were proportional to the sulphur content and remained constant at a given sulphur content under the oxygen pressure between 50∿500 mmHg, the reaction was found to be of the first order with respect to the sulphur content. From the results that the recarburization reaction occurred during the reaction and the rate of carbon removal was proportional to square root of the oxygen pressure, it was shown that each of these two reactions took place independently in the melt. The rates of desulphurization were influenced by the content of carbon and that tendency corresponded with the activity of sulphur in the melt. The specific rate constants were much smaller than the lime slags.
