A method for controlling a continuous casting machine, a control device for a continuous casting machine, and a method for manufacturing a slab

摘要

The control apparatus 10 of the continuous casting machine which is one Embodiment of this invention uses the operating conditions of the continuous casting machine 1, and the temperature data of the molten steel in a mold, The molten steel which estimates the flow state of the molten steel in a mold on-line. Molten steel for online calculation of the molten steel flow index, which is a factor in which impurities are mixed into the slab in the mold, based on the flow state estimation unit 11 and the flow state of the molten steel estimated by the molten steel flow state estimation unit 11 A flow index calculation unit 12, and an operating condition control unit 13 for controlling the operating conditions of the continuous casting machine 1 so that the molten steel flow index calculated by the molten steel flow index calculation unit 12 is within an appropriate range, have.
