By the use of a descending probe set on the burden surface and equipped with thermo-couples at a given interval, temperature distribution in vertical and radial direction in a blast furnace can be measured as it goes down with burden material. To estimate the location of the probe in the furnace, an experiment was carried out by a small-sized cylindrical model, and it was found that the middle point of the probe descended in accordance with a stream line of the burden material at the same radial. From this result, a method was presented to estimate the location of the probe in the furnace. The isotherms were obtained by analyzing the temperature distributions measured at Kakogawa No.1 blast furnace. The 1200℃ isotherm was in a good agreement with the outer profile of melting zone observed after the dissection of the furnace. At Kobe No.2 blast furnace, the change of isothermas was investigated with the change of coke rate and 1200℃ isotherm in the peripheral part was kept at a constant level by the burden distribution control to maintain the stable operation.
