Abstract The progress in energy saving and environmental protection of ironmaking system in China is reviewed since 1990s. Due to the introduction of PCI technology in BF, the investment for coke ovens has been reduced greatly, the energy consumption and pollution have been really reduced at the source. Based on the analysis of secondary energy in ironmaking system, the elimination of small sintering machine and BFs, the promotion of the technologies, such as use of TRT, high efficiency drytype deduster for BF gas, power generation on BFG and energy recovery in sintering are the key points in future for energy saving and mitigation of CO2.
