The fatigue life of bearing steel is closely related to the total oxygen content in the steel.Aimming at the control of T[O]in the bearing steel during refining process,a calculation model of optimal basicity for the refining slag CaO-SiO2-MgO-Al2O3-FeO at 1 853 K is established,based on the ion and molecule coexistence theory（IMCT）.And the influence factors on optimal basicity for the slag system are discussed and analyzed.The results show that:①For different FeO content,the maximum value of NFeO occured when the basicity are all around 3,the optimal basicity basically does not change with the variation of FeO content.②The content of MgO has a great influence on the optimal basicity,with the increase of MgO content,the optimal basicity decreased.③The effect of Al2O3 content on the optimal basicity is opposite to that of MgO.With the increase of Al2O3 content,the optimal basicity increases significantly.
