Abstract
A method of electromagnetically stirring molten steel in continuous casting is disclosed wherein in producing cast slabs or blooms, an electromagnetic stirring force is applied to the unsolidified molten steel in the cast slab or bloom being drawn. An electromagnetic stirrer is installed between drawing positions where the unsolidified thickness is 45% and 15%, respectively, of the thickness as viewed in the direction of the thickness of the cast slab or bloom. Stirring in the casting direction is applied to the unsolidified molten steel in such a manner that the product of the magnetic flux density (gauss) at the interface between the unsolidified and solidified portions and the stirring time in minutes (which is defined as the ratio of the effective stirring length (in m) of the electromagnetic stirrer to the casting speed (in m/min) is 1,600 gauss-min or more per m<3> of the total volume (m<3>) of unsolidified molten steel present in a region extending to the drawing side from the position where the electromagnetic stirrer is located.
