The invention discloses an alkali-resistant castable for a working lining of a lime rotary kiln as well as a preparation method and application of the alkali-resistant castable. The feed comprises the following raw materials in parts by mass: 100 parts of premixed granules; 50 to 55 parts of premixed fine powder; 9-13 parts of a monopotassium phosphate solution; wherein the premixed particle material comprises magnesium aluminate spinel particles and calcium hexaluminate particles; the premixed fine powder comprises magnesium rhodonite fine powder, enstatite fine powder, zirconium boride fine powder and amorphous Al2O3 fine powder. The alkali-resistant castable for the working lining of the lime rotary kiln prepared by the invention is good in construction performance, and after the alkali-resistant castable is poured into the working lining of the lime rotary kiln, additional heat treatment or firing is not needed, so that energy is saved; the castable is high in high-temperature strength, low in volume density, small in heat conductivity coefficient, high in alkalinity, high in alkali corrosion resistance, free of ring formation and easy to adhere to slag crust; the fluidity of the castable is good, and the overall sealing performance of the working lining of the lime rotary kiln is good; the alkali-resistant castable does not generate toxic and harmful components before and after construction, and is environment-friendly.
本发明公开了一种石灰回转窑工作衬耐碱浇注料及其制备方法和应用。本发明包括如下质量份数的原料：预混颗粒料100份；预混细粉料50～55份；磷酸二氢钾溶液9～13份；其中，预混颗粒料包括镁铝尖晶石颗粒和六铝酸钙颗粒；预混细粉料包括镁蔷薇辉石细粉︰顽火辉石细粉︰硼化锆细粉︰无定形Al2O3细粉。本发明所制备的石灰回转窑工作衬耐碱浇注料施工性能好，浇注成石灰回转窑工作衬后，无需额外的热处理或烧成，节约能源；浇注料高温强度大，体积密度低，导热系数小，碱度高、抗碱侵蚀能力强，不结圈且易挂渣皮；浇注料流动性好，石灰回转窑工作衬的整体密封性良好；耐碱浇注料在施工前后无毒害组分产生，环境友好。
