It is important to forecast decreasing heat levels in order to stabilize the quality of pig iron in a blast furnace. Kobe No. 3 B.F. is installed with 28 FM sensors- T (Doubly Sheathed Sensor with Multi Fine Thermocouples) which are located on the 4 locations at 7 levels from shaft to bosh of the furnace wall. These sensors can measure the temperatures in blast furnace with high accuracy. The temperatures measured by FM sensor- T are analyzed statistically in correlation with the pig iron temperature. Based on the analysis, a forecasting system far decreasing heat levels has been developed and applied to Kobe No. 3 B.F.Through an on-line test of this system, the successful forecasting rate for decreasing heat levels was raised to 86%, and the alarm failure rate was 2%. The present system can be used as a guidance system for furnace operators.
