钢铁工业是国民经济发展的支柱型产业,钢铁工业的节能降碳是实现国家"碳达峰、碳中和"发展目标的重中之重.文章简要介绍了主流低碳氢冶金炼铁技术的种类及特点,阐述了国内外低碳氢冶金炼铁技术的进展及现状.高炉富氢还原技术和氢基竖炉直接还原技术是最主要的低碳氢冶金炼铁技术.其中,高炉富氢还原技术降碳能力有限,可作为钢铁行业短期低碳氢冶金炼铁技术的发展方向,如结合碳捕集利用封存(CCUS)技术,可进一步降低CO2排放量.氢基竖炉直接还原技术从源头上摆脱了化石能源的应用,与传统"高炉-转炉"生产流程相比,可降碳80%以上,是钢铁工业工艺技术变革必然发展趋势.包钢积极响应国家绿色低碳发展战略及内蒙古五大任务,积极布局绿色低碳氢能炼铁技术于白云鄂博中贫矿的氢基矿相转化、高炉富氢还原及氢基竖炉直接还原技术,钢铁生产过程低碳绿色化明显提高.
Discussions on Progress of Low Carbon Ironmaking Technologies with Hydrogen Metallurgy and Approaches of Ironmaking Technology with Hydrogen in Baotou Steel
The iron and steel industry is the pillar industry in national economic development as well as its energy con-servation and carbon reduction are the priority among priorities to achieve the national development goal of"carbon dioxide emission and carbon neutrality". In this paper,it is briefly introduced the types and characteristics of main low carbon ironmaking technologies with hydrogen metallurgy as well as expounded its progress and current situations at home and a-broad. The hydrogen rich reduction technology with blast furnace and hydrogen-based direct reduction technology with shaft furnace are the main technologies of low carbon ironmaking technologies with hydrogen metallurgy. Among them,the ability of carbon reduction for hydrogen rich reduction technology with blast furnace is limited,so it can be as short-term development direction of low carbon ironmaking technologies with hydrogen metallurgy for iron and steel industry. If com-bine with the carbon capture,utilization and storage (CCUS)technology,CO2 emissions could be further decreased. The hydrogen-based direct reduction technology with shaft furnace is without fossil energy in production process and carbon e-missions could be reduced by over 80% compared with traditional production process of"blast furnace-converter",which is inevitable development trend of technological reform in the iron and steel industry. In order to actively respond to the na-tional green and low carbon development strategy and five major political tasks of Inner Mongolia,Baotou Steel actively im-plements the green low carbon ironmaking technologies with hydrogen including hydrogen-based mineral phase transforma-tion of medium lean ore in Bayan Obo,hydrogen rich reduction with blast furnace and hydrogen-based direct reduction with shaft furnace so that the low carbon green production process of iron and steel is significantly improved.
