   有色冶炼主要包括铜、铅、锌、镍、锑、锡等,轻金属冶炼以铝和镁为主。冶炼设备有闪速炉,伊萨麦炉,奥斯麦炉,底吹氧炉,BAIYIN炉等。要求耐火材料具有较长的寿命,节能,不污染环境,安全及较少维修。所用耐火材料包括:低蠕变,高荷软的硅线石、红柱石砖,莫来石砖,各种直接结合、半再结合、再结合熔铸砖和镁铬砖,镁铝尖晶石砖,氧化硅结合或赛隆结合碳化硅砖。同时近几年不定形耐火材料在有色冶炼工业的应用正在逐渐受到重视,如高耐磨性,高抗渣性和热稳定性优良的浇注料,抗剥落性优良的钢纤维增强的浇注料以及自流浇注料、捣打料、可塑料、干式料、喷补料、预铸块等应用比例逐年增长。耐火砖的侵蚀机理在熟料煅烧过程中,由于回转窑内气体温度比物料温度高得多,回转窑每旋转一圈,回转窑衬表面受到周期性的热冲击,温度变化幅度为150-250℃,在回转窑衬10-20mm表层范围内产生热应力。
      回转窑衬还承受由于回转窑的旋转而产生的砖砌体交替变化的径向和轴向机械应力,以及煅烧物料的冲刷磨损。由于同时产生硅酸盐熔体,在高温环境下很容易与回转窑衬耐火砖表面相互作用形成初始层,并同时沿耐火砖的孔隙渗入到耐火砖的内部,与耐火砖黏结在一起,使耐火砖表层10-20mm范围内的化学成分和相组成发生变化,降低耐火砖的技术性能。
      当物料的烧结范围较窄或者形成短焰急烧产生局部高温时,会使回转窑皮表面的最低温度高于物料液相凝固温度,回转窑皮表面层即从固态变为液态而脱落,并且由表及里深入到回转窑皮的初始后又形成新的回转窑皮初始层。当这种情况反复出现时,烧成带回转窑衬就逐渐由厚变薄,甚至完全脱落,导致局部露出回转窑筒体而红回转窑。实际上烧成带回转窑衬损坏情况正是如此,在高温区域残砖厚度大体上呈曲率半径较大的弧线分布,有时弧底就落在回转窑简体的内表面上。
