STEEL CONTINUOUS CASTING METHOD AND IN-MOLD MOLTEN STEEL FLUIDITY CONTROLLER

摘要

Electronic Brake? In the combined electromagnetic stirring coil, we shall also outstanding meniscus under electromagnetic stirring performance. ; By energizing a direct current or three-phase alternating current to the electromagnetic coil disposed on the outer long side of the mold, a method for a continuously cast steel by selectively applying a magnetic brake or an electromagnetic stirrer in the intra-mold molten steel. Electromagnetic coil (5) is, on each long side having a 2n different tooth portion (5a), each tooth portion (5a) is subjected to each winding (5c) on the outer side, also for two, winding (5d) on the outer side the performing merges into one. Be placed on each tooth portion (5a) of the vertical direction of the magnet coil (5) to the core portion (5b) the meniscus from the immersion nozzle 1, the ejection holes (1a) ranges having location. When the molten steel 2 in the mold (3) was stirred e, methoxy electromagnetic force induced in the meniscus under the molten steel (2), a discharge port (1a) two times or more of the electromagnetic force is induced in the position of the immersion nozzle 1, do. ; Even under the meniscus may form a good stirring flow.
