A 3200 cubic meter blast furnace at the Novolipetsk Metallurgical combine was used to optimize gas flow by selecting a proper charging system and other parameters of the smelting operation. The radial distribution of hydrogen and carbon dioxide in the top of the blast furnace was changed and changes in the vent area were evaluated. It was found that increasing the area of the axial vent appeared to stabilize the pig iron composition and increase furnace productivity while reducing the sulfur content and making the basicity of the slag constant. Efficiency of gas use improved and unit coke consumption decreased.
