چکیده
M. Szega, W. Stanek Silesian University of Technology, Gliwice, Poland L. Blacha Silesian University of Technology, Katowice, Poland The reduction of energy consumption in the blast furnace is still the subject of investigations using mathematical modelling of a blast furnace plant. Theoretical-empirical hybrid models of a blast furnace and its equipment have been presented. This model is built based on the mass and energy balances of furnace zones and empirical data from the measurement of a blast furnace. The results of a numerical simulation of the injection of auxiliary fuels and the top-gas recirculation after the removal of CO2 to the blast furnace have been presented.

Blast Furnace Analysis with Neural Networks
Nowadays blast furnace operation is supervised by extensive measurements and controlled accordingly. Characteristic indications concerning process quality are given by the analysis of the radial temperature profile in the upper part of the furnace. Optimising this temperature distribution would lead to considerable savings of input material. To achieve an optimisation, quantitative relations be...
