摘　　要：为了解决镁砂竖窑烧成带耐火材料与煅烧的原料发生粘结问题,本研究选择了4种碱性烧成耐火材料与菱镁矿在1700℃×3h、0.2MPa压力下进行粘结试验。结果表明:电熔再结合镁铬砖与菱镁矿反复进行10次试验均未发生粘结,是烧成带所用耐火材料的理想选择。In order to solve the problem that refractory sticks with raw material at the magnesia shaft kiln burning zone during burnt process,the study chose four basic burnt refractories to conduct the sticking test with magnesia at 1700 ℃ for three hours under 0. 2 MPa pressure. The results show that rebounded electrically fused magnesia-chrome brick is an ideal kind of refractory at burning zone,because it did not stick with magnesia for ten times experiments.
