本文介绍了中国高炉炼铁的概况，以及在节能、高炉温、大型化设备等方面的技术进展。随后，深入阐述了炼铁技术的科学发展观。内容包括：加强钢铁产业结构调整，转变发展方式，转变观念。在高品位炉料的基础上，以低碳炼铁为目标，寻求适当的冶炼强度，合理的富氧和PCI，提高高炉温度，降低焦炭率。改善燃气分配和能源利用，降低爆炸、电力等各类能耗。减少排放，加强无害化处理。从而在低消耗、高效率、高质量、长寿命、环保等方面取得了新的突破。同时，要坚决整顿炼铁生产乱象，禁止落后产能回流或继续生产。综上所述，节能减排和低碳炼铁是中国实现高炉炼铁科学发展的核心步骤。
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.
