METHOD AND APPARATUS FOR CONTROLLING THE FLOW OF MOLTEN STEEL IN A MOULD |
摘要 |
Method for controlling a flow of molten steel in a mould by applying at least one magnetic field to the molten steel in a continuous slab casting machine. Controlling a molten steel flow velocity on a molten steel bath surface to a predetermined molten steel flow velocity by applying a static magnetic field to impart a stabilizing and braking force to a discharge flow from an immersion nozzle when the molten steel flow velocity on the meniscus is higher than a mould powder entrainment critical flow velocity. Controlling the molten steel flow velocity on the meniscus to a range of from an inclusion adherence critical flow velocity or more to a mould powder entrainment critical flow velocity or less by applying a shifting magnetic field to increase the molten steel flow when the molten steel flow velocity on the meniscus is lower than the inclusion-adherence critical flow velocity. |
