This paper describes a method for interpretation of temperature distributions measured by an above‐burden probe in a blast furnace. The distributions are approximated by polynomials, based on which indices are computed and depicted graphically in order to track the evolution of the gas distribution in the shaft. Using the indices, both gradual and abrupt (spontaneous) changes in the gas flow patterns have been detected. The indices can also be used to verify whether burden distribution control actions have led to desired results, and to detect imbalance in the gas flow.
