摘要： “双碳”目标下,氢冶金技术成为行业焦点,其中氢基竖炉直接还原法为主流工艺,其操作环境对耐火材料抗还原性气体侵蚀性能要求极高。铝硅系耐火材料因其优异的力学性能、抗侵蚀性等,被广泛应用于工作层与保温层,其适用性和蚀损机制也备受关注。为此,总结了铝硅系耐火材料在还原气氛下的热力学稳定性,阐述了影响还原反应的多种因素,分析讨论了铝硅系耐火材料在还原气氛下的演变机制,并对未来铝硅系耐火材料抗还原性气体侵蚀的研究方向进行了展望。

关键词: 低碳冶金, 铝硅系耐火材料, 还原性气氛, 侵蚀机制

Abstract: Under the goal of “double-carbon”,hydrogen metallurgy technology has become the focus of the industry.The hydrogen-based shaft furnace direct reduction method is a mainstream process,and its operating environment has extremely high requirements for the resistance of refractories to reducing gas corrosion.Al₂O₃-SiO₂ refractories are widely used in the working layer and insulation layer due to their excellent mechanical properties and corrosion resistance,and their applicability and corrosion mechanisms have garnered significant attention.The thermodynamic stability of Al₂O₃-SiO₂ refractories in the reducing atmosphere was summarized.Various factors affecting the reduction reaction were described.The evolution mechanism of Al₂O₃-SiO₂ refractories in the reducing atmosphere was analyzed and discussed.The future research direction for enhancing the resistance of Al₂O₃-SiO₂ refractories to reducing gas corrosion was prospected.

Key words: low carbon metallurgy, Al₂O₃-SiO₂ refractories, reduction atmosphere, corrosion mechanism
