In this paper, an overview of blast furnace ironmaking in China and technological progress in fields of energy-saving, high blast temperature, large-scale equipment etc. are introduced. Subsequently, scientific development concept of ironmaking technologies is deeply exposited. The contents include: Strengthen adjustment of ironmaking industrial structure, change development model and change concepts. On the base of high-grade burden, aiming at low-carbon ironmaking, seek proper smelting intensity, rational oxygen-enrichment and PCI, increase blast temperature and decrease coke rate. Improve gas distribution and energy utilization, lowering all types of energy consumption involving blast and power etc. Decrease emission and strengthen innocuous treatment. Thus some new breakthrough in the aspects of low consumption, high efficiency, high quality, long campaign life and environment protection are achieved. Meanwhile, resolute measures should be taken to rectify the disorder in ironmaking production and prohibit backward production capacity return or continue producing. To sum up, energy-saving, emission reduction and low-carbon ironmaking are the central steps of realizing scientific development of blast furnace ironmaking in China.
