摘　　要：非高炉炼铁是钢铁工业实现低碳冶金的重要方向之一,在国外已进行了近百年的研究,出现了"直接还原"和"熔融还原"等十余种新工艺,但迄今都尚未能成功取代高炉,表明其创新难度很大。介绍了基于钢铁冶金与有色冶金"学科交叉"思维所提出的将有色工业成熟的"闪速冶金"工艺拓展用于炼铁在基础理论与试验研究方面所做的工作与进展,提出了以"煤基常压气化-飘浮闪速炼铁"为技术特征的非高炉炼铁新工艺,并介绍了其产业化的初步设计方案。Non-blast furnace iron-making is one of the important directions to realize low carbon production in iron and steel industry.It has been studied for nearly a hundred years in foreign countries,and there are more than ten kinds of new processes,such as "direct reduction" and " melt reduction".However,it is a pity that blast furnace has not been successfully replaced so far,which shows that it is very difficult to innovate non-blast furnace iron-making technologies.The work and progress of the basic theory and experimental research of expanding the "flash metallurgy" process used widely in non-ferrous industry to iron-making were introduced,which is based on the thought of "interdisciplinary" between ferrous metallurgy and non-ferrous metallurgy.A non-blast furnace iron-making process characterized by "coal-based atmospheric gasification-suspended flash iron-making" was put forward,and the industrial design scheme and progress of the new iron-making process were also introduced.
