摘　　要：通过对比镁锆砖和镁铬砖抗RH炉渣侵蚀机理以及简化模型法,研究了镁锆砖的制备工艺参数与抗RH炉渣侵蚀的相关性.利用正交试验的方法分析了颗粒级配、助烧剂、烧结温度、氧化锆含量和氧化锆种类对镁锆砖抗渣性能的影响,确立影响镁锆砖抗渣性能的关键因素为烧结温度和氧化锆含量.在此基础上进一步分析烧结温度和氧化锆含量对镁锆砖抗渣侵蚀性能的影响.通过统计分析手段,利用中心复合设计,建立镁锆砖的抗侵蚀统计分析模型,并作响应曲面图形.The relation between preparing parameters of magnesia-zirconia bricks and their resistance to RH slag corrosion was studied by contrasting the slag resistance behaviors of magnesia-zirconia bricks and magnesia-chromite bricks and by a simplified model. The preparing parameters that influence the RH slag resistance properties of magnesia-zirconia bricks, such as grain mixture ratio, agglutinant, sintering temperature, zirconia content, and variety of zirconia, were analyzed by orthogonal experimental design （OED）. The results indicate that sintering temperature and zirconia content are two key influencing factors. The effects of sintering temperature and zirconia content on the ratio of infiltrate depth were further examined by the steepest ascent method and central composition design （CCD）, and a statistic analysis model of resistance corrosion of magnesia-zirconia bricks eroded by RH slag was built.
