摘　　要：以柳钢1 500 m3高炉球式热风炉损毁球床为研究对象,分析三段式球床从上至下存在粉化、变形黏结、粉体球体混合黏结的损毁原因:刚玉质耐火球的尖晶石化、高温荷重下高铝质耐火球的变形黏结以及中温下Φ45 mm高铝质耐火球与粉体混合黏结等3种因素共同作用。By studying on the damaged refractory pellet bed in pebble stove of 1 500m3 Blast Furnace of Liuzhou Steel, the damaged causes of pulverizing, deforming and bonding, mixed bonding of powder and pellet existing in three-zone pellet bed were analyzed： the spinellization of corundum refractory pellet, the deforming and bonding of high-alumina refractory pellet under the high-temperature load and the mixed bonding of Φ45 mm high-alumina refractory pellet and powder under the medium temperature were three combined causes to damage the pellet bed.
