摘要在国家提出“碳达峰”和“碳中和”的背景下,钢铁企业的绿色改革迫在眉睫。钢铁企业的化石燃料消耗和CO₂排放主要来源于高炉炼铁工序,高炉富氢冶炼技术可以有效降低高炉焦炭消耗和CO₂排放,高炉内H₂体积分数的增加将使焦炭的性能演变过程发生较大变化,因此,探索这一变化过程对高炉生产的稳定顺行和节能减排尤为重要。综述了高炉富氢后对焦炭的气化反应、微观结构以及软熔带渣铁-焦界面熔蚀过程影响的研究现状。与传统高炉不同,高炉富氢冶炼加大了低温区焦炭的气化反应失重率,但是高温条件下焦炭的气化过程主要发生在表面,这抑制了高温区焦炭反应后强度的降低;高炉软熔带渣铁对焦炭的侵蚀减少,同时焦炭表层灰分质量分数较大,阻碍了渗碳反应的发生。在此基础上对需要进一步深入研究的问题进行了展望,为富氢高炉生产以及焦炭的选择提供参考。

Abstract：Under the development background of "carbon peak" and "carbon neutral" proposed by China, the green reform of iron and steel enterprises is imminent. The fossil fuel consumption and CO₂ emission of iron and steel enterprises mainly come from the blast furnace(BF) ironmaking process. The hydrogen-rich smelting technology of BF can effectively reduce the coke consumption and CO₂ emission. The increase of H₂ volume fraction in the BF will greatly change the coke property evolution process. Exploring this change process is particularly important for the stable and smooth production and energy conservation and emission reduction of BF. The effects of hydrogen-rich smelting in BF on coke gasification reaction, microstructure and melting erosion process of slag-iron-coke interface in cohesive zone are reviewed. Different from the traditional BF, the hydrogen-rich smelting of BF increases the weight-loss rate of coke gasification reaction in the low temperature zone, but the gasification process of coke under high temperature conditions mainly occurs on the surface, which inhibits the reduction of coke strength after reaction in the high temperature zone. The corrosion of slag iron in the cohesive zone of BF to coke reduces, and the high ash content in the coke surface layer hinders the occurrence of carburizing reaction. On this basis, the problems to be further studied are prospected, providing reference for hydrogen-rich BF production and coke selection.

Key words： blast furnace hydrogen-rich smelting coke gasification microstructure corrosion
