“…While direct experiments are difficult to conduct yielding accurate estimates but mathematical models produce approximate results, often due to simplified approach. Conventional methods [2][3][4][5][6] for detecting the position of cohesive zone are the direct experimentation using descending probe inside blast furnace or, using the wall thermocouples installed at different positions on the blast furnace. Modern methods use sophisticated mathematical models [7][8][9][10][11][12][13] of blast furnace internal processes combined with actual plant process measurements to predict the shape of the cohesive zone online.…”

It is common practice in many blast furnaces to use the shape and position of the cohesive zone as a control guide for burden distribution. Knowledge of the location and shape of the cohesive zone will help to have better control over the blast furnace process and improve its thermal efficiency and productivity. Accurate estimation of the shape and location of the cohesive zone was believed to aid this objective. Hence for achieving better accuracy along with affordability to be used as a continuous monitoring method, a combined modelling approach of using furnace operating and probe data along with mathematical estimation model was attempted for estimating cohesive zone shape and location. Further, comparative evaluation was done with respect to current method adopted in Tata Steel based on process data analysis, for a given blast furnace.Both combined modelling approach and current method adopted in Tata Steel were found equally capable in predicting the cohesive zone root location but the combined modelling approach seemed to be better in predicting the overall shape of cohesive zone.

This work reviews the issues of modeling of the operating modes for a blast furnace and identification of areas of unimprovable solutions on a set of indicators of cast iron output, coke consumption, and thermal state. These areas define the boundaries of potential opportunities for achieving high values of quality of the blast-furnace processes on a set of real-life operating modes of a blast furnace. They also indicate the reserves of coke consumption reduction and output enhancement, which might be implemented by optimal choice of a blast furnace operating mode and which enable the reasonable choice of the operating mode of a blast furnace based on the potential opportunities for increasing the output, minimizing coke consumption for the specified coke quality and the specified requirements to the furnace thermal state.
