摘　　要：采用实验模拟和现场取样的方法研究了有害元素对复合棕刚玉砖的蚀损机理,研究表明:复合棕刚玉砖具有较好的抵御渣、铁和Pb、Zn侵蚀渗透的能力,而对碱金属K、Na的抗渗透能力较差,炉缸复合棕刚玉砖蚀损是有害元素共同作用的结果,侵入砖体的顺序依次是K、Na、Zn、Pb。The erosion mechanism of hazardous elements to composite brown corundum brick was investigated by experimental simulation and in-situ sampling methods. The research results reveal that composite brown corundum brick has good ability to resist the erosion of molten slag and iron as well as Pb and Zn,but it is easily being eroded by alkalis K and Na. The erosion of composite brown corundum brick in the hearth is caused by the hazardous elements. The order of hazardous element erosion into the brick is K, Na, Zn, Pb.
