REAL-TIME ESTIMATE OF BLAST FURNACE THEORETICAL COMBUSTION TEMPERATURE BASED ON THE VARIATION OF GAS UTILIZATION RATE AND COKE RATIO

摘要

The thermal state is an important index to evaluate the blast furnace (BF) operation. Method of rapid and accurate real-time estimation of the thermal state has always been one of hot research topics. Although the measurements of hot metal temperature, silicon content and other indicators are used to judge the thermal state inside BF, it is difficult to be applied in practical production as a result of hard realtime detection.
