摘　　要：针对攀钢高钛金属化球团熔分用电炉的工况条件,选择炭砖及七种含碳耐火材料作为研究对象,借助热力学计算和动态抗渣试验探讨应用这些材料的可行性。结果表明,在不考虑氧化的前提下镁质或铝质耐火材料中引入高含量C和SiC组分有利于提高其抗熔分渣侵蚀能力;综合考虑认为,引入高SiC含量的镁碳化硅碳材料或铝碳化硅碳材料是高钛金属化球团熔分用电炉炉衬的最佳候选。The possibility of carbon block and other seven selected carbon containing materials used as lining materials of melting and separation furnaces were investigated by thermodynamic calculation and dynamic slag resistance test under considering the operating conditions in Panzhihua Iron and Steel Co.. The results showed that it is benefit to improving high Titanium slag resistance of MgO-based or Al2O3- based refractory by introducing high content carbon or SiC under not considering their oxidation. It is suggested that Al2O3-SiC-C or MgO-SiC-C with high SiC content would be one of the best candidate materials for Pangang melting and separation furnaces for high Titanium content metalized pellets.
