Electromagnetic stirring is used at billet molds as well as at slab mold, to get high quality steel at continuous casting in a steel making plant. In order to get the same electromagnetic force in each billet mold and thus the same quality, phase characteristics of electromagnetic stirring is investigated. From the calculation result, it is found that the relative phase at which the difference of the electromagnetic torque in each mold becomes the smallest is 0 or 240 deg. To apply the phase characteristics of the EMS to the quality control, we propose the dynamic phase control system by two inverters to get the high quality in the surface crack.
