Abstract The new technology of blast furnace coal injection combines traditional technology of blast furnace with gas-making furnace and achieves a rational use of top gas through top gas recycling. The results show that with the increase of the cycle time，the amount of coal required increases，the content of H2 and CO in the gas-making furnace increases，and the total heat input and heat budget of blast furnace decrease. With the volume fraction of H2 and CO in the top gas increasing，the volume fraction of N2 and CO2 decreasing and the circulation of gas，the gas composition is basically unchanged，and the optimum running state of the blast furnace is guaranteed.
