By adjusting the slag system of 12 Mn steel refining and optimizing the CaO/Al2O3ratio,the desulfurization rate of the slag system is increased,the melting temperature is reduced,and the oxygen content in the steel is diminished.The results showed that the CaO/Al2O3 ratio decreased from the average value of 3.29 to 1.64,which caused the melting point decrease and the desulfurization rate increase.Finally,the effect of CaO/Al2O3 value in the range of 1.4～1.7 was verified by the desulfurization rate and oxygen content in steel.This study is of great significance to the adjustment of refining slag system of 12 Mn steel.
