Description

一种刚玉莫来石隔热复合砖
技术领域
本发明涉及耐火材料领域，具体涉及一种刚玉莫来石隔热复合砖。
背景技术
回转窑是个燃烧器、热交换器、反应器和输送器等合而为一的多功能高温设备，在建材、冶金、化工、环保等许多生产行业被广泛使用，随着我国现代工业迅猛发展，回转窑煅烧技术日趋成熟，为了满足煅烧要求，对回转窑内衬耐火砖质量的要求越来越高，现今回转窑内衬用砖为二层，内保温层为轻质粘土砖，外耐火层为重质耐磨砖，但是在总体厚度不变的情况下，重质层耐火砖厚度比较薄，达不到使用寿命就要脱落，导致内保温层耐火砖很快也被损坏，致使回转窑整体温度升高，导热红窑停产，因此需要对现有的回转窑内衬耐火砖需要进一步的改进。
发明内容
为解决上述现有技术的不足，本发明提供一种刚玉莫来石隔热复合砖解决了回转窑内衬耐火砖使用寿命短，容易脱落，导致回转窑整体温度高，设备运转率低，能耗消耗高的问题。
本发明由以下技术方案实现：
一种刚玉莫来石隔热复合砖，包括重质部分、轻质部分和保温部分，所述的重质部分由重量百分比的：高铝矾土34%、刚玉粉30%、莫来石15%、红柱石15%、优质粘土6%制成，所述的轻质部分由焦宝石40%、轻质莫来石骨料50%、优质粘土10%组成，所述的保温部分为锆铝陶瓷纤维板。
进一步的，所述的重质部分占刚玉莫来石隔热复合砖总量的60%并聚集于一端，所述的保温部分占刚玉莫来石隔热复合砖总量的10%并聚集于另一端，所述的轻质部分占刚玉莫来石隔热复合砖总量的30%并位于重质部分与轻质部分之间。
进一步的，所述的重质部分和轻质部分用波浪形的钢模隔开。
进一步的，所述的一种刚玉莫来石隔热复合砖的制备方法：
将重质部分和轻质部分的原料分别各自按照上述比例混碾，在模腔中插入波浪形钢板，将混碾好的重质部分和轻质部分分别放入模腔中波浪形钢板的两侧，用2500T的液压制砖机加压成型，进入烘干窑烘干，将烘干好的半成品放入隧道窑内，在1480℃的温度下烧结，将烧结后的成品与陶瓷纤维板使用高温胶泥粘结在轻质部分的外侧并使用木托盘包装好。
该刚玉莫来石隔热复合砖在使用时相对于现有的仅使用刚玉莫来制作的石砖可以有效降低壳体温度50-80℃，在体积相同的情况下，刚玉莫来石隔热复合砖相对仅使用刚玉莫来制作的石砖重量减轻15%，有效减轻了回转窑负荷，而且现有的仅使用刚玉莫来制作的石砖导热系数大、比重大，经常会导致回转窑中部托轮等动力设备温度过高使其受到损坏，因此需要每3个月需要检修一次，如有损坏及时更换，并且仅使用刚玉莫来制作的石砖的使用寿命只有8-10个月，而刚玉莫来石隔热复合砖使用寿命为12-18个月，采用双层隔热材料，由于其比重轻，降低了中部托轮的温度及回转窑重量，因此延长了设备的使用寿命，而且刚玉莫来石隔热复合砖还具有高耐磨、抗侵蚀、热震稳定性和低导热性能，节能降耗，绿色环保。
附图说明
图1为本发明的主视图。
图2为本发明的俯视图。
具体实施方式
实施例1：
如图1和图2所示，一种刚玉莫来石隔热复合砖，包括重质部分1、轻质部分2和保温部分3，所述的重质部分1由重量百分比的：高铝矾土34%、刚玉粉30%、莫来石15%、红柱石15%、优质粘土6%制成，所述的轻质部分2由焦宝石40%、轻质莫来石骨料50%、优质粘土10%组成，所述的保温部分3为锆铝陶瓷纤维板，所述的重质部分1占刚玉莫来石隔热复合砖总量的60%并聚集于一端，所述的保温部分3占刚玉莫来石隔热复合砖总量的10%并聚集于另一端，所述的轻质部分2占刚玉莫来石隔热复合砖总量的30%并位于重质部分1与轻质部分2之间，所述的重质部分1和轻质部分2用波浪形的钢模隔开；
该刚玉莫来石隔热复合砖的制备方法为：先将重质部分1和轻质部分2的原料分别各自按照上述比例混碾，在模腔中插入波浪形钢板4，将混碾好的重质部分1和轻质部分2分别放入模腔中波浪形钢板4的两侧，用2500T的液压制砖机加压成型，进入烘干窑烘干，将烘干好的半成品放入隧道窑内，在1480℃的温度下烧结，将烧结后的成品与陶瓷纤维板使用高温胶泥粘结在轻质部分2的外侧并使用木托盘包装好。
使用刚玉莫来石隔热复合砖时，将其与高温胶泥配套砌筑使用，砌筑方法严格按照回转窑砌筑规范，砌筑完毕后，按照升温曲线升温至投料温度即可进入正常生产，刚玉莫来石隔热复合砖适合于1200℃-1500℃热态工作环境。
