PROBLEM TO BE SOLVED: To express with higher accuracy, a final solidification position and a final solidification shape in a continuous casting.SOLUTION: A solidification state estimation device estimates the solidification state of a casting slab 5 in a continuous casting process for manufacturing the casting slab 5 continuously, by solidifying the molten steel charged into a casting mold by performing a secondary cooling while drawing the casting slab in a plurality of cooling zones, with a heat transfer model using a heat flux Q based on a cooling condition of at least a secondary cooling. A heat flux distribution correction portion 22b is provided, which corrects the heat flux Q of the heat transfer model with the correction coefficient dwhich is a preliminarily set value and varies along a width direction. |
