As an important part of steel smelting, direct reduced iron production requires the exploration and application of low-carbon and environmentally friendly smelting technologies. As an emerging ironmaking technology, hydrogen-rich metallurgy technology has the advantages of high resource utilization rate and low environmental pollution, and has received extensive attention in recent years. In this paper, the principle of hydrogen-rich metallurgy technology is introduced, the hydrogen-rich metallurgy technology and research progress at home and abroad are systematically analyzed, the development trend of hydrogen-rich metallurgy technology is summarized, and the problems existing in the industrial application of hydrogen-rich metallurgy technology are analyzed from such 4 aspects as lack of high-grade iron ore resources, selection of reducing agent, many difficulties in technology research and development, and difficulty in coupling green hydrogen production from renewable energy with metallurgical process. In order to provide reference for the development and industrialization of hydrogen-rich metallurgical technology, the 4 optimization strategies are proposed, including optimizing the hydrogen-rich preparation process, optimizing the reduction process parameters, deepening technological innovation, and controlling and optimizing process.
