摘要

PROBLEM TO BE SOLVED: To know the degree of internal damage of a refractory material provided in an apparatus. SOLUTION: A first model building unit 130 uses the amount of surface damage of a refractory material measured every time the device is used a plurality of times, and the amount of surface damage up to the number of times the device is used is input. Build a first model that outputs. The second model building unit 150 outputs the temperature of the outer surface of the refractory in response to the input of the amount of surface damage, the amount of heat applied to the device, and the temperature of the heated surface of the refractory at each use of the device. Build a model. The outer surface temperature estimation unit 160 estimates the temperature of the outer surface in a new use of the device by using the second model. The internal damage amount estimation unit 170 determines the thermal resistance of the fireproof material obtained based on the temperature estimation value of the outer surface at the new usage time and the measured value of the inside temperature of the equipment, and the outside temperature of the equipment at the new usage time. And the value of the difference from the thermal resistance of the fire-resistant material obtained based on each measured value of the inside temperature is calculated as an index showing the amount of internal damage of the fire-resistant material.
