The lining erosion measuring system for blast furnace has been developed. This system consists of double sheathed multiple thermocouple (FMT Sensor : Fine Multi Thermo-Sensor) and computer software for the estimation of lining erosion of refractory wall (Trigger-Response method). The sensor can simultaneously measure the temperature variations at a number of positions across the thickness of the lining. The Trigger-Response method can calculate the remaining thickness of lining by analyzing the time-delay occuring in the propagation of temperature variations in the lining. By analyzing the signals out of FMT-Sensors by the Trigger-Response method, the extent of erosion of the refractory lining is estimated within an error tolerance of less than 5%. These techniques have been successfully systematized to on-line lining erosion monitoring system for blast furnace. Also, this paper describes the newly developed Ansatz Measuring Sensor of which principle is based on the application of FMT-Sensors. It is considered that signals out of FMT-Sensor may carry the useful data as operation guidance for blast furnace.
