| 摘 要： | 选取高炉出铁沟耐火材料常用的5种骨料(分别为棕刚玉、电熔刚玉、亚白刚玉、富铝尖晶石和特级矾土,粒度均为5～10 mm)和攀钢高炉钛渣(w(TiO2)=26%)作为研究对象,通过相图热力学计算和静态坩埚侵蚀试验对比研究,探讨了攀钢高炉钛渣条件下出铁沟耐火骨料的选择.热力学计算表明,电熔刚玉具有良好的抗钛渣侵蚀能力,而特级矾土骨料被侵蚀后形成的新渣相黏度高,有利于阻止渣对耐火材料的进一步渗透;而静态坩埚试验结果难以反映和判断材料高温下侵蚀的反应过程.因此,相图热力学计算技术可作为分析耐火材料侵蚀情况的可靠方法和手段.

| Abstract: | Five kinds of aggregates(brown corundum,fused corundum,sub-white corundum,alumina-rich spinel and special grade bauxite,the particle size were 5-10 mm) and BF TiO_2-containing slag of Pansteel were chosen for comparing according to thermodynamics phase calculation and static crucible corrosion test.The results showed that fused corundum had the best corrosion resistance to the BF TiO_2-containing slag;and the new slag phase formed by special grade bauxite reacting with slag had higher viscosity,which could ... |
