基　　金：This research was funded by the Ministry of Science and Technology of the People’s Republic of China with Grant number 2020YFB1712801 for study on material flow,energy flow,cost flow,information flow,control flow and their coupling mechanism in steel production.

摘　　要：Carbon dioxide(CO_(2))emissions have become an important factor limiting the high-quality development of the Chinese steel industry.To achieve the goal of carbon peak and carbon neutrality,the strategic planning and technological layout of low-carbon development have been carried out by the Chinese steel industry and enterprises.Based on the summary and analysis of the technology roadmap of low-carbon development in the steel industry and an evaluation of the current research progress of low-carbon technologies,the prospects for the low-carbon development of the steel industry in the future were provided.The results indicate that some steel enterprises in China have already released their low-carbon development roadmaps with a focus on achieving carbon neutrality,which will be realized through advancements in system energy efficiency improvement,resource recycling,process optimization and innovation,breakthrough in smelting technology,product iteration and upgrading,and carbon capture,utilization,and storage(CCUS).The technology development of hydrogen metallurgy and CCUS has shown rapid progress.In the future,the Chinese steel industry must continue to prioritize low-carbon technology and promote the utilization of clean energy.The ratio of electric arc furnace steel should be increased gradually,and the development and application of CCUS technology should be promoted,to ensure the achievement of the“carbon peak and carbon neutrality”goal.
