Abstract：the status of gas recovery and utilization in iron and steel industry in China was analyzed and the affluent gas amount was more and more with the steel increasing, gas recovery and continuous casting process adopted. The method of gases utilization efficient was studied from preheating the combustion air, fuel and mixing the high CV gas; the means of gas dynamic balance were studied from constructing the energy management center and enforcing gas management; and discussed the mode of “purchasing coal only, no purchased electricity” in iron and steel works from selecting the generating electricity power models with excess gases in different works, and the feasibility of gas regenerative utilization was researched from chemical way utilization of gases. It was recognized that for the integrated iron and steel works if all kinds of gas were produced from technological processes, were recovered and stored, effective energy saving measures, gas utilization methods and scientific management of gases were implemented, the gas would be zero emission and be able to supply power and chemical products outside.
