Abstract In order to achieve the green and low cost ironmaking，Mei Steel will perform the BF operation with coke oven gas（COG） injection. And for insuring the effective injection，the mathematical modeling research of Mei Steel No. 2 BF with COG injection is researched. Firstly，based on the raw material and fuel conditions of Mei Steel No. 2 BF，the mathematical modeling of the BF operation with COG injection is carried out by multi-fluid blast furnace model. Secondly，the economic benefit after COG injection is also preliminarily analyzed. Compared with the base case of no COG injection，when the COG injection is 50 m3/t（Fe），the concentration of reducing gas in the BF increases and the reduction is accelerated；the production increases to 4 740 t/d（increases 30.12%）；the coke rate decreases to 321.80 kg/t（Fe）（decreases 14.43%）；the carbon emission decreases to 355.93 kg/t（Fe）（decreases 8.61%）. On the base of the coke price of 1 607 RMB/t and the COG price of 0.774 9 RMB/m3（supplied by Mei Steel in Nov 2016），the cost of pig iron reduces 20.14 RMB/t，the saved coke for COG injection is 7.79 ten thousand tons per year，and the total economic benefit is 51.15 million RMB per year. Considering the economic benefit，the coke saving potential，the rich oxygen capacity，and the COG surplus of Mei Steel，it is recommended that the rational COG injection for Mei Steel No. 2 BF is maintained around 50 m3/t（Fe）.
