The electromagnetic stirring is applied to continuous casting process of steel. A set of linear motor type stirrers is used for slab caster. High promotive force is fit for equiaxed crystallization of slab. The rotary motor type stirrer with 2 poles by 2 phases is used for bloom caster. Equiaxed crystallization of bloom is saturated in relatively low promotive force. Double stirrers system is more effective for equiaxed crystallization without heavy white band. Equiaxed crystallization by electromagnetic stirring reduces the centerline segregation of strand. The quality of products through continuous casting with electromagnetic stirring is therefore better than that through ingot casting.
