In order to improve steel quality in the continuous casting process, it is necessary to make the dynamic behavior of the free surface flows in a mold clear. The estimation of influences of in-mold electromagnetic stirring (M-EMS) electromagnetic force is especially important. We examined the difference of free surface flows by the different M-EMS exciting frequencies, using numerical experiment (magnetohydrodynamic calculation). We introduce a new index, the responsive ratio, to evaluate it. As a result, the free surface flow has different behavior according to exciting frequency and its responsive ratio is higher in low-frequency zone. The free surface flow has also high resonate-ability with natural frequency of the mold.
