A method of monitoring the operation of a blast furnace. The distance x, y to the surface of the glowing mass located in the raceway 12 formed in front of a tuyere 6 is measured by a distance meter 13 placed at an inspection window 11 located in or near the tuyere 6. The distance is measured for a plurality of the tuyeres of the furnace, and if any of the measured distances deviates more than a predetermined value from the mean value for the measured distances, the deviation indicates a fault in the furnace process and that a correction is required. <IMAGE> |
