Cement kiln collaborative disposal technology realizes the "reduction, harmlessness, and resourceization" of garbage, and has achieved good social benefits, environmental benefits and economic benefits. However, due to a large amount of harmful ingredients such as sulfur, alkali, and chlorine in garbage waste, it is enriched in the cement kiln heater system, which causes refractory bricks to be easily eroded, peeled, and damaged. At present, aluminum silicon products in the low -temperature zone of cement rotation kiln, such as silicon -silicon martyrs, anti -peeling high aluminum bricks, and new low aluminum Mo Lai stone bricks, etc., the differences in raw materials and physical and chemical performance are obvious. In this work, compare the alkali corrosion performance of different products above, and combine the analysis of the micro structure and the composition of objects to determine its quality of anti -alkali erosion performance, and then optimize the
