摘　　要：我国钢铁工业巨大的产能规模、以煤为主的能源结构、以高炉-转炉为主的冶炼流程导致其面临巨大的减碳压力,是国家兑现"碳达峰碳中和"承诺的主战场之一。通过对我国钢铁工业的发展现状与趋势分析、基于工序的我国钢铁工业碳排放分析、典型钢铁冶炼低碳技术分析、我国钢铁工业低碳发展路径浅析等全面梳理了我国钢铁工业的碳排放现状,并为我国钢铁工业低碳技术的研发提出了若干建议,以期为我国钢铁工业"碳中和"愿景的如期实现提供参考。The huge plant capacity,the coal-based energy supply and the smelting circuit composed mainly of blast furnace-converter in Chinese steel industry leads to a great pressure for carbon emission reduction.It is one of the main battlefields for the country to fulfill its commitment to carbon peak and carbon neutral.Based on the analysis on current situation and developing trend,working procedure for carbon emission,typical low carbon smelting processes,the route for low-carbon development of Chinese steel industry and so on,some recommendations were made for the research and development of low-carbon technologies of Chinese steel industry.This paper is aimed at providing reference for Chinese steel industry to reach the goal of carbon neutral as scheduled.
