Flint clay raw material synthesized from high-alumina coal gangue and preparation method of flint clay raw material
The invention discloses a flint clay raw material synthesized from high-alumina coal gangue and a preparation method thereof, coal gangue as solid waste is taken as a raw material, the raw material is wide in source and low in cost, and the problems of low volume density, high water absorption and the like caused by the fact that the flint clay raw material is generally prepared by directly calcining the coal gangue are solved by adding a small amount of auxiliaries in the calcining process. Compared with the flint clay clinker prepared by a common process, the volume density of the prepared calcined Jianbao clinker is improved by about 10% or more, the mullite phase proportion is improved by 10-15%, the cristobalite phase is obviously reduced, the water absorption rate is reduced and the strength is improved at the same temperature, and the prepared flint clay raw material has higher heat resistance and thermal stability.
本发明公开一种高铝煤矸石合成焦宝石原料及制备方法，本发明以作为固废的煤矸石为原料，原料来源广，成本低，通过煅烧过程中少量助剂加入，解决了一般采用煤矸石直接煅烧制备焦宝石原料出现的体积密度低、吸水率高等问题。本发明制备煅烧焦宝熟料体积密度比一般工艺制备焦宝石熟料约提高10％以上，莫来石相占比提高10‑15％，方石英相明显降低，相同温度下吸水率降低，强度提高，制备焦宝石原料具有更高的耐热性和热稳定性能。
