Aluminum-silicon castable added with alpha-Al2O3 micro powder and preparation method thereof
The invention discloses an aluminum-silicon castable added with alpha-Al2O3 micro powder and a preparation method thereof, and the treatment method comprises the following specific steps: in the first step, the raw materials mainly comprise the following components: calcium aluminate cement, floating beads, sinking beads, silicon micro powder, alpha-Al2O3 micro powder and perlite; in the second step: 1) pouring 26-38% of calcium aluminate cement, 5-10% of floating beads, 3-9% of sinking beads, 2-6% of silica powder, 0-12% of alpha-Al2O3 micro powder and 40-50% of perlite in corresponding parts by mass into a stirrer, and uniformly stirring the raw materials, 2) adding a proper amount of water into the stirrer, and stirring for 3 minutes to form slurry, and in the third step: 1) pouring the slurry into a mold. According to the method, the construction efficiency can be improved, meanwhile, the water consumption in the construction process can be reduced, meanwhile, the stability of the volume of the castable can be maintained, and a better application prospect can be brought in the field of unshaped refractory materials.
本发明公开了一种添加α‑Al2O3微粉的铝硅系浇注料及其制备方法，该处理方法具体步骤如下：一种添加α‑Al2O3微粉的铝硅系浇注料及其制备方法，步骤一中所述原材料准备的组分主要包括：铝酸钙水泥、漂珠、沉珠、硅微粉、α‑Al2O3微粉和珍珠岩，步骤二包括：1)、将相应质量份数的铝酸钙水泥26％～38％、漂珠5％～10％、沉珠3％～9％、硅微粉2％～6％、α‑Al2O3微粉0～12％和珍珠岩40％～50％倒入到搅拌机内，并将原材料搅拌均匀，2)、向搅拌机内加入适量的水搅拌，形成浆料，搅拌的时间为3min，步骤三包括：1)、将上述浆料倒入模具内。本发明能够提高施工效率，同时能够降低施工过程中的用水量，同时有利于维持浇注料体积的稳定性，在不定形耐火材料领域能够带来更好的应用前景。
