要約(英語): This paper reports an estimation result of thermal conductivity and thermal expansion coefficient for insulating firebrick model with radiation from heating furnace. The insulating firebrick is used for blast furnace in steel industry and exposed to high temperature environment. In this situation, it is difficult to specify physical characteristics such as thermal conductivity and thermal expansion coefficient because the measurement methods regulate allowable measurement ranges for temperature. Moreover the physical characteristics change as time passes. That is, the estimation of physical characteristics is essential to model the dynamics and keep the control performance considering active safety. It also indicates that the characteristic of the model obtained by the estimation becomes the basis of green innovation. Therefore, this paper models an insulating firebrick with radiation from heating furnace and tries to estimate thermal conductivity and thermal expansion coefficient through extended Kalman filter and experimental data. From the result, it found that the physical characteristics could be estimated by the input and the output data about insulating firebrick.
