Description

低导热高耐磨硅莫复合隔热砖的制备方法
技术领域
本发明属于耐火材料的技术领域，具体涉及一种低导热高耐磨硅莫复合隔热砖的制备方法。
背景技术
目前水泥窑用的硅莫逐渐出现了重质和轻质工作层相结合的复合砖，但由于轻质工作层材料的特性，结构强度比较低，所以主要以重质砖为主。重质砖的导热系数较大，使得窑筒体外壁温度较高，加大熟料热耗，引起熟料单位成本增加；另一方面筒体受热膨胀，致使窑中部托轮瓦温度升高，筒体过热增加了机械设备的损坏几率、加速了筒体变形，容易掉砖。因此若能使用即具有耐火，还具有隔热双重性能的复合砖，可以有效的使筒体温度降低，减少散热损失，而且也有利于设备维护，提高设备运转率。
发明内容
本发明的目的在于针对现有技术的不足，提供一种低导热高耐磨硅莫复合隔热砖的制备方法。为实现上述目的，本发明所采用的技术方案是：

（4）成型后的砖坯由进入干燥窑干燥；
（5）干燥后的砖坯装窑，在窑内进行烧成，在弱还原性气氛下，烧成温度为1480~1530℃，保温6~12小时，冷却后得到低导热高耐磨硅莫复合隔热砖。
