Apparatus for controlling flow of molten steel in mold |
摘要 |
An apparatus for controlling a flow of a molten steel in a mold, the apparatus including: a casting-condition acquiring unit for acquiring at least five casting conditions; a calculating unit for calculating a molten steel flow velocity on a molten steel bath surface in accordance with the acquired casting conditions; a determining unit for determining whether the acquired molten steel flow velocity is higher or lower than a mold-powder entrainment critical flow velocity; a control unit for applying a shifting magnetic field to impart a braking force to a discharge flow from an immersion nozzle and applying a shifting magnetic field to rotate the molten steel in a horizontal direction; and a shifting magnetic field generating apparatus.
