Improved coke and agglomerate quality make it possible to intensify NLMK blast furnace operation by increasing gas pressure in the bell, blast flow rate, oxygen concentration within it, and injected fuel flow rate. BF specific productivity increases by 15–30% with a simultaneous reduction in fuel consumption. An increase in smelting intensity with respect to oxygen and reducing gas generated in the hearth increases indirect reduction of wustite and its efficiency.
