In this paper, research on CO2 utilization in the sintering, blast furnace, converter, secondary refining, continuous casting, and smelting processes of stainless steel in recent years in China is carried out. Based on the foreign and domestic research and application status, the feasibility and metallurgical effects of CO2 utilization in the ferrous metallurgy process are analyzed. New techniques are shown, such as flue gas circulating sintering, blowing CO2 through a blast furnace tuyere and using CO2 as a pulverized coal carrier gas, top and bottom blowing of CO2 in the converter, ladle furnace and electric arc furnace bottom blowing of CO2, CO2 as a continuous casting shielding gas,CO2 for stainless steel smelting, and CO2 circulation combustion.
