Kiln lining composite brick
The invention provides a kiln lining composite brick which comprises a silicon nitride and silicon carbide combined ceramic layer and a sialon and aluminum oxide combined hollow sphere layer combined with the silicon nitride and silicon carbide combined ceramic layer, wherein the silicon nitride and silicon carbide combined ceramic layer is close to a working surface of a kiln and is in direct contact with gas in the kiln. The composite brick adopts a double-layer structure, the silicon nitride and silicon carbide combined layer has the effects of corrosion resistance, wear resistance and the like, and the sialon and aluminum oxide combined hollow sphere layer has the effects of heat insulation and heat preservation, so that the problems of peeling and slag falling caused by corrosion of kiln gas and repeated high-temperature aging of the inner-layer brick of a kiln are solved by combining the two layers, and meanwhile, the good heat preservation and heat insulation effect of the outer-layer brick is achieved.
本发明提出了一种窑炉内衬复合砖，包括氮化硅结合碳化硅陶瓷层和与之相结合的塞隆结合氧化铝空心球层，所述氮化硅结合碳化硅陶瓷层靠近窑炉工作面，与炉内气体直接接触。本发明复合砖采用双层结构，其中氮化硅结合碳化硅层具有耐侵蚀、耐磨等作用，塞隆结合氧化铝空心球层具有隔热保温的作用，将两者结合起来不仅解决了窑炉内层砖受窑炉气体的侵蚀和反复高温老化而出现剥落和掉渣的情况，同时也满足了外层砖的良好保温隔热效果。
