摘要：

In this paper, the development process of iron and steel metallurgy technology and discipline is sorted out, and its development process is divided into five main periods. In the new era, the iron and steel metallurgical industry will change from the pursuit of efficiency priority to the direction of energy conservation and environmental protection, this paper summarizes the green and low-carbon development path of the iron and steel industry, and focuses on the development direction of hydrogen-based low-carbon ironmaking technology. Hydrogen-rich blast furnace technology represented by COURSE50, ULCOS, and tkH2Steel can be used as the preferred direction for blast furnace process improvement at this stage. In terms of non-blast furnace processes, this paper introduces the development of hydrogen-based shaft furnace direct reduction ironmaking processes such as MIDREX and HYL/ENERGIRON, and also introduces the hydrogen-based direct reduction ironmaking processes of iron ore powder using fluidized beds, such as H-Iron, FIOR, Circored and HyREX. In the new era, China's iron and steel industry should make full use of low-carbon energy sources such as coke oven gas, coal-to-gas, natural gas and green hydrogen while developing traditional energy-saving and emission reduction technologies, so as to reduce carbon consumption and CO2 emissions. © 2024 Chemical Industry Press Co., Ltd..
