Document Type and Number:
WIPO Patent Application WO/2020/170563
Kind Code:
A1
Abstract:
A control unit 10 for a continuous casting machine according to an embodiment of the present invention is provided with: a molten steel flow state estimation unit 11 that uses an operation condition of the continuous casting machine 1 and temperature data about a molten steel inside a cast mold, to estimate online the flow state of the molten steel inside the cast mold; a molten steel flow index calculation unit 12 that calculates online a molten steel flow index serving as a cause for infiltration of impurities into a cast slab inside the cast mold on the base of the flow state of the molten steel estimated by the molten steel flow state estimation unit 11; and an operation condition control unit 13 that controls the operation condition 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.
