摘　　要：从炼铁新技术及基础理论研究方面介绍了烧结球团提质降耗新技术、焦炭在高炉内行为解析研究、高炉喷吹清洁燃料技术、高炉长寿技术、高炉炼铁数据建模技术以及冶金尘泥再处理技术.从基础研究出发,提出了目前最具有潜力的炼铁新技术;然后在国家碳中和战略的大背景下,综述了目前国际上的非高炉炼铁技术研究进展,为我国低碳炼铁发展提供依据;最后从最新微观研究手段出发,介绍了目前炼铁研究领域在微观尺度的研究进展,多尺度综合调控研究高炉炼铁过程机理,为未来低碳炼铁发展方向提供思路.The Chinese government made a statement at the 75th United Nations General Assembly in 2020 to increase the country’s nationally determined contributions,adopt more effective policies and measures,strive to reach the peak of carbon dioxide emissions by 2030 and achieve carbon neutrality by 2060.In recent years,with the rapid development of the iron and steel industry,the iron and steel industry has been promoted by various measures such as large-scale equipment,high-efficiency energy utilization,and reduction of pollutant emissions.Moreover,this industry has gradually made efforts to achieve low-carbon emissions.However,due to the particularity of the steel industry’s process system,the steel industry is still the main battlefield in China’s carbon emission reduction.The ironmaking process accounts for the largest proportion of energy consumption and emissions in the entire process of iron and steel smelting.Annual CO_(2)emissions of the iron and steel industry account for 6.7%of total global emissions,of which the energy consumption and emissions of the ironmaking system account for the total energy consumption of the entire iron and steel process,facing the important challenge of saving energy and emission reduction.To adapt to the trend and realize the transformation and upgrading of the ironmaking industry,various processes of the ironmaking industry have made great efforts in reform and innovation in recent years.This article introduces the new technology of sintering pellet quality improvement and consumption reduction from the aspects of new ironmaking technology and basic theoretical research,analysis of coke behavior in the blast furnace,blast furnace clean fuel injection technology,blast furnace longevity technology,blast furnace ironmaking data modeling technology,and metallurgical dust and mud reprocessing technology.Starting from basic research,the new ironmaking technology with the most potential is proposed.Then,under the general background of the current national carbon neutral strategy,the
