Abstract
A device includes: an input device configured to receive an input of measurement results of a temperature and components of molten steel in a tundish of continuous casting facilities, measurement results of a width, a thickness, and a casting speed of a cast slab casted in the continuous casting facilities, and molten steel flow rate distribution in a mold; a model database configured to store a model expression and a parameter related to solidification reaction of molten steel in the mold; a convertor configured to convert a molten steel flow rate in the mold into a heat conductivity parameter; and a calculator configured to estimate a solidified shell thickness in the mold based on temperature distribution of the mold and steel in the mold calculated by solving a three-dimensional transient heat conduction equation using the measurement results.
