摘　　要：对高炉炉身下部用不烧 Al2 O3 -C质耐火材料在水蒸气环境下的抗氧化性能进行了全面的氧化性能实验。通过对大量的实验结果进行归纳和分析 ,总结出其氧化规律 ,建立了不烧 Al2 O3 -C质耐火材料的氧化动力学模型。此外 ,还对氧化前后试样的抗折强度进行了测定和比较。Complete experiment of oxidation resistance character of unsintered Al 2O 3 C refractory used for the lower stack of a blast furnace in water vapor were made. According to the analysis on many experimental results, the oxidation regularity was concluded; the oxidation kinetic model was established. Besides, the strengths of samples before and after oxidation were measured and compared.
