高铝致密耐火浇注料抗爆裂性能的影响因素

Effect of various factors on explosive spalling resistance of high-alumina dense refractory castable

水泥窑窑口、窑头罩等部位所用耐火浇注料容易发生爆裂,为此制备了高铝致密耐火浇注料试样进行了抗爆裂试验。试验结果表明:1)适当增加水泥加入量能够提升高铝致密耐火浇注料的抗爆裂温度;2)防爆纤维材质对高铝致密耐火浇注料的抗爆裂性能有较明显的影响;3)防爆纤维的长度和直径在一定范围内对高铝致密耐火浇注料的抗爆裂性能影响不明显。

The refractory castables used in cement kiln outlet,kiln hood and other parts is easy to explosive spalling,so the high-alumina dense refractory castable sample is prepared to carry out the anti-crack test.The test results show that:1)explosive spalling resistance temperature of high-alumina dense refractory castables can be improved by increasing the amount of the cement;2)the explosion-proof fiber material has obvious influence on the explosive spalling resistance of high-alumina dense refractory castables;3)the length and diameter of explosion-proof fiber have no obvious influence on the explosive spalling resistance of high-alumina dense refractory castables in a certain length and diameter range.
