Abstract：The process contrast tests with M-EMS stirring intensity and [S]% was carried out， MnS inclusion scanned and statistics with Aspex， make comparison among the different process for the same testing area after conversion and unified the results that about the length of single inclusion and ratio of inclusion area. Result shows lager possibility of big size pure MnS separated in the steel which content more sulfur； possibility of big size pure MnS separate increased with the greater stirring intensity； besides， nucleation possibility of compound state MnS increased， formation of bigger size compound MnS was promoted at the same time. Conclude that based on the control of low [S]% to add nucleating agent while smelting and choose the proper stirring intensity could be helpful for MnS inclusion separate control， and improve the technological level of inclusion control in railway steel at last.
