Abstract：In this paper,a 45 steel continuous casting round billet with a diameter of 210 mm is used as the research object.By comparing the effects of compound electromagnetic stirring(M+F-EMS)and using mould electromagnetic stirring(M-EMS)alone on carbon segregation in continuous casting round billets,the influence of M+F-EMS parameters on the carbon segregation index of continuous casting round billets is determined.The results show that the carbon bias index fluctuation is smaller when using M+F-EMS than when using M-EMS alone.The optimal M+F-EMS parameters are M-EMS:2 Hz/200 A.F-EMS:8 Hz/250 A.
