Abstract
A method for controlling a flow of molten steel in a slab continuous casting machine including controlling a molten steel flow velocity on a molten steel bath surface to a predetermined flow velocity by applying a shifting magnetic field; controlling the molten steel flow velocity on the molten steel bath surface from an inclusion-adherence critical flow velocity or more to a mold-powder entrainment critical flow velocity or less by applying a shifting magnetic field; and controlling the molten steel flow velocity on the molten steel bath surface from the inclusion-adherence critical flow velocity or more to the mold-powder entrainment critical flow velocity or less by applying a shifting magnetic field.
