Using Mathematical Simulation to Evaluate the Efficiency of Iron Ore–Coal Brexes in Blast-Furnace Smelting

Resumo

A mathematical model of the blast-furnace process developed by the MISiS is used to analyze the efficiency of a charge containing, in equal portions, coal-containing brexes made of iron-ore concentrate, superfluxed sinter, and non-fluxed oxidized pellets. Mathematical simulation shows that replacing 50% of sinter production by clean brex production will reduce the coke consumption by at least 10% and the dust and gas emissions of sintering plants by 50%.
