Surface modification method of used cement kiln silicon mullite brick and iron runner castable
The invention relates to a surface modification method of a used cement kiln silicon mullite brick and an iron runner castable, and the method comprises the following steps: firstly, soaking the used cement kiln silicon mullite brick in water, cleaning, airing and drying to obtain a pretreated cement kiln silicon mullite brick; then taking a silica sol aqueous solution as an impregnation liquid, and fully impregnating the pretreated cement kiln silicon-mullite brick in the impregnation liquid to obtain an impregnated cement kiln silicon-mullite brick; and finally, drying the impregnated cement kiln silicon mullite brick to obtain the modified cement kiln silicon mullite brick. The volume density of the modified cement kiln silicon mullite brick obtained by the method is increased, and the apparent porosity and the water absorption rate are reduced; the modified cement kiln silicon mullite brick is applied to the high-quality iron runner castable, the use amount of brown aluminum oxide is reduced, the cost is low, the anti-seismic property is good, and the resource utilization problem of the used cement kiln silicon mullite brick is effectively solved.
一种用后水泥窑硅莫砖的表面改性方法及铁沟浇注料，首先将用后水泥窑硅莫砖浸水清洗、晾晒并烘干，得到预处理后的水泥窑硅莫砖；然后以硅溶胶水溶液作为浸渍液，将预处理后的水泥窑硅莫砖充分浸渍在浸渍液中，得到浸渍后的水泥窑硅莫砖；最后将浸渍后的水泥窑硅莫砖烘干后制得改性水泥窑硅莫砖。通过该方法得到的改性水泥窑硅莫砖体积密度增加、显气孔率和吸水率降低；将改性水泥窑硅莫砖应用到质铁沟浇注料，减少棕刚玉的用量，成本低，抗震性能好，有效解决用后水泥窑硅莫砖资源化利用问题。
