ABSTRACT OF THE DISCLOSURE There is disclosed a method of monitoring the wear of refractory walls of a blast furnace. Temperature is sensed at different point across the thickness of the furnace walls and thermal representations of the internal phenomena of the blast furnace are derived as trigger signals. Analysis is carried out on the correlation between the trigger signals and variations in the temperatures of the furnace walls in terms of delay time, thus predicting the present status of the wear of the furnace walls. A temperature probe assembly is also disclosed which is useful in sensing the temperature distribution in the refractory walls. The temperature probe assembly includes a plurality of parallel sheath type thermocouples or thermometers.
