Energy-saving light-weight castable for mouth of cement kiln and preparation method of energy-saving light-weight castable
The invention belongs to the technical field of refractory materials, and relates to an energy-saving light-weight cement kiln mouth castable and a preparation method thereof. The energy-saving light-weight cement kiln mouth castable is prepared by taking 60-70 parts of light-weight lanthanum aluminate-mullite aggregate, 5-10 parts of silicon carbide fine powder, 8-12 parts of alumina fine powder, 4-8 parts of tabular corundum fine powder, 1-3 parts of alpha-Al2O3 micro powder, 1-6 parts of lanthanum zirconate fine powder and 4-6 parts of calcium aluminate cement as raw materials, adding a water reducing agent and water, stirring, forming, demolding and baking. The castable prepared by the invention is excellent in thermal shock resistance and erosion resistance, high in heat radiation efficiency, low in cost and simple and convenient in preparation process, reduces heat loss while greatly prolonging the service life of a kiln mouth refractory material, and has a good application prospect.
本发明属于耐火材料技术领域，涉及一种节能型轻量水泥窑窑口浇注料及其制备方法。本发明以60~70份的轻量铝酸镧‑莫来石骨料、5~10份的碳化硅细粉、8~12份的矾土细粉、4~8份的板状刚玉细粉、1~3份的α‑Al2O3微粉、1~6份的锆酸镧细粉、4~6份的铝酸钙水泥为原料，外加减水剂和水，搅拌，成型，脱模，烘烤，制得节能型轻量水泥窑窑口浇注料。本发明制备的浇注料热震稳定性及抗侵蚀性能优异，热辐射效率高，成本低，制备工艺简便，在大幅提高窑口耐火材料使用寿命的同时降低热损失，应用前景良好。
