“…From one side, its introduction in the iron ore mixture (containing sinter and pellets) can improve gas permeability of charge [6][7][8] and intensify the reduction processes if iron oxides [9-11], but from other side, it has negative effect on permeability of coke packing in the furnace hearth [12][13][14], what can be explained by its not complete consumption before the hearth. It is demonstrated especially clear in the furnaces equipped with tray-type compact bellless top (BLT) that can't always provide uniform charge composition around the top throat [15][16][17]. In its turn, this fact causes excess of some components (i.e.…”

The effect of coke nut introduction in charge material (in the amount 10.9-12.8 kg per ton of hot metal) on operation parameters of blast furnaces with volume 1370 and 2014 m 3 have been established via industrial investigations. These blast furnaces are operating in the conditions of bottom and top areas determining by their gas dynamics. Parameters of gas dynamic conditions, fuel burning, iron reduction from FeO using different reducing agents, furnace thermal operation and hearth drainage capacity are analyzed.
