摘　　要：“闪速炼铁”是基于学科融合思维,将有色冶金行业成熟的闪速熔炼方法拓展用于炼铁的一项非高炉炼铁工艺与工程技术,目标是实现低能耗、低投资、规模化的近零碳炼铁。本文综述了闪速炼铁技术(简称闪铁)已完成的实验室试验及中试试验成果,同时,就该技术的未来产业化进行评估。结果显示,闪铁可高效处理低品位复杂矿,取消球团烧结、球化、焦化等原料预处理工段,可实现零碳排放,易于规模化,可实现一步炼钢,综合能耗指标优于现有高炉炼铁工艺(闪铁吨钢351 kgce<高炉吨铁553 kgce)。“Flash ironmaking”is a non-blast furnace ironmaking process and engineering technology based on the cross-disciplinary integration,which extends the mature flash smelting process of non-ferrous metallurgical industry to ironmaking.Its goal is to achieve near-zero carbon ironmaking with low energy consumption,low investment and large scale.In this paper,the laboratory and pilot test results of flash ironmaking technology(flash iron for short)were summarized,and the future industrialization of this technology was evaluated.The results show that the flash iron can efficiently treat low-grade complex ore,cancel the raw material pretreatment section such as pellet sintering,spheroidization and coking,achieve zero carbon emission,easy to scale,and realize onestep steelmaking.The comprehensive energy consumption(351kgce per ton steel)of flash iron is less than that of the blast furnace ironmaking process(553kgce per ton iron).
