Abstract In order to get a lower fuel ratio and BF smooth operation after the use of high performance coke， the relationship between the high temperature performance of coke and coke burden was studied. The high temperature performance of coke has an important influence on BF coke burden. Since the medium-capital overhaul of Shouqin No.1 BF， several suitable blast parameters have been chosen according to the blast system and operation profile with high-quality CDQ. Through the strengthen management of raw materials and BF tapping， and reasonable regulation of the upper and lower gas distribution， the operation of high coke burden was achieved under the condition of economic burden. Under the pressure of limiting production， the tuyere area was reduced by 11.38% . Meanwhile， reasonable blast parameters were adopted to lengthen the raceway depth and maintain the stability of the hearth. Moreover， the narrow and strong central gas distribution with a stable edge temperature formed. Production practice shows that under the condition of an average slag ratio up to 433.30 kg/t， the coke burden is improved to 6.01 t·t－1 with the average fuel ratio 499.17 kg/t. It is proved that the fuel consumption could be reduced effectively by the use of high-quality coke.
