摘要： PROBLEM TO BE SOLVED: To calculate a future temperature even in a part, where temperature measuring data is not present, with high precision without being restricted by the present period of the temperature measuring data when the behavior of the future temperature of the measuring target is estimated.
SOLUTION: The thickness of the measuring target changed in its thickness and temperature accompanied by the elapse of time is increased and decreased from an aspect of calculation on the basis of the thickness of the known data not only to calculate heat history with respect to a plurality of the increased and decreased thicknesses but also to measure the temperatures of respective regions obtained by dividing the analyzing area set to the surface of the measuring target into a plurality of regions. The temperature of one region of the respective regions is measured only for a predetermined time and the thickness of the measuring target is specified on the basis of the measured value to estimate the future temperature of the measuring target with the specified thickness.

摘要： PROBLEM TO BE SOLVED: To simultaneously determine a heat transmission coefficient α between a mold and a solidified shell which is a main cause that governs the condition within the mold, and a heat transmission coefficient β between a molten steel and the solidified shell.SOLUTION: In continuous casting, there are heat conductors such as a solidified shell 2, a mold powder layer 3, and a mold 4 between a molten steel 1 and a cooling water for the mold. An estimating method for the condition in a mold estimates the condition in the mold by acquiring a heat transmission coefficient α between the solidified shell 2 and the mold 4 as well as a heat transmission coefficient β between the molten steel 1 and the solidified shell 2. Using a plurality of thermocouples 5 embedded in the mold 4, each of them deviated along molding direction, the thermal flux that passes the mold is acquired. The heat transmission coefficient α and the heat transmission coefficient β are simultaneously determined by using the thermal flux and an equation which contains the heat transmission coefficient α and the heat transmission coefficient β to represent a thermal flux that passes the mold.
