Abstract In order to reduce the CO2 removal and gas preheating cost during the oxygen blast furnace ironmaking process. The current study put forward an oxygen blast furnace with coke oven gas injection （OBF-COGI） ironmaking process. Then， the material and energy balances mathematical model of the new process was established. Based on the model， the process parameters of traditional blast furnace （TBF）， TBF-COGI， OBF （blast oxygen content of 30%， 40%， 50% and 100%）-COGI were calculated and compared. The results show that a small amount （30 m3/t） of COGI into the TBF can reduce the fuel ratio 13 kg/t compared with TBF， COG replacement coke ratio is 0.433 kg/m3， but has little impact on the other parameters. With the increase of blast oxygen content， the reduction potential of OBF-COGI raises， the CO and hydrogen utilization rate decreases. There exists a reducing agent apparent excess in the furnace. There is no N2 enrichment phenomenon in the non full OBF-COGI process. The total calorific value of external supply gas gross in new process is 3 000 MJ/t which has little change compared with the TBF. So the new process has almost no effect on the gas supply and demand balance in present iron and steel enterprise. Compared with the current blast furnace ironmaking process， the full OBF-COGI process can save coke by 43%， increase coal by 33% and reduce fuel ratio by 20%.
