摘　　要：对近年来炼铁工业的进展与挑战、低碳炼铁技术的最新进展、高炉实现低碳炼铁的技术路径等问题进行了分析认为,目前我国高炉炼铁工业必须坚持科学发展,坚持精料方针,积极发展和推广高炉低碳炼铁技术;与此同时,要重视氢冶金技术的基础研究,重视非高炉低碳炼铁(直接还原与熔融还原)技术的发展;只有鼓励科技创新,炼铁行业才能尽快适应我国经济发展与环境保护的新要求。This paper analyzes the progress of the ironmaking industry,the challenges faced,the latest developments of low—carbon ironmaking technology,and the technical approach to realizes low carbon BF ironmaking.It is believed that China’s BF ironmaking industry must implement scientific development,popularize the utilization of beneficiated burden material,and promote low-carbon BF ironmaking technology.In addition,it is imperative to place a high value on the basic research of hydrogen-based metallurgical technology and development of non-blast furnace low carbon ironmaking(direct reduction and smelting reduction)process.The ironmaking industry only can rapidly adapt to the new requirements of China's economic development and environmental protection through constant technological innovation.
