Blast-furnace smelting with the injection of natural gas and coke-oven gas

A multizone mathematical model developed at Nekrasov Institute of Ferrous Metallurgy reveals the internal relations between the processes in a blast furnace. Using this model, the smelting processes and parameters in two different blast furnaces are investigated with wide variation in the flow rates of natural gas and coke-oven gas and in the distribution of the materials over the furnace radius. New scientific and practical findings are reported.
