Since putting into operation the No.1 1 880 m3 BF in Laiwu Steel has kept long-term smooth operation by continuing exploration and perfecting the furnace operation, strengthening raw material and basic management. Through ensuring uniformity and activity of hearth, controlling reasonable gas flow distribution, rational theoretical combustion temperature, reasonable coke batch, and implementing low silicon smelting and appropriately increasing alkalinity in slag, the perfect operation system in inner of BF was established;through controlling original fuel quality, ensuring accurate distribution charge, etc, the door for original fuel into BF could be hold;by strengthening device management, tapping iron management in cast house, the basic management was strengthened. The excellent technical and economic indicators included coal ratio 168 kg/t, coke ratio 355 kg/t and fuel ratio 523 kg/t were achieved.
