Abstract：The total oxygen content in 410S ferritic stainless steel after AOD reduction were calculated by deoxidization thermodynamics. And the total oxygen mass fraction，the type and morphology of the inclusions，and the chemical composition of the slag taken from the smelting process were investigated and identified to study the forming reason of the inclusions. The results showed that the total oxygen mass fraction calculated by deoxidization thermodynamics was in good agreement with that obtained by detection. The total oxygen mass fractions decreased gradually with the increase of silicon mass fraction after AOD reduction process. And the total oxygen mass fraction and the conclusion size both decreased throughout the AOD-LF-CCM process. The type of the inclusions at the final stage of the AOD and LF was mainly CaO-SiO2-MgO-Al2O3 inclusion，and whose mass fractions of each component were different but close to the slag chemical composition of each stage. Additionally，the variation of the inclusion composition was related to the temperature drop.
