Castable containing nano magnesium aluminate spinel
The invention belongs to the technical field of castables, and particularly relates to a castable containing nano magnesium aluminate spinel. The castable containing the nano magnesium aluminate spinel is prepared from the following raw materials: fused white corundum or sintered tabular corundum aggregate and fine powder, fused or sintered magnesia-alumina spinel fine powder, active alpha-Al2O3 micro powder, pure calcium aluminate cement and a water reducing agent. The castable is characterized in that nano magnesium carbonate and nano aluminum hydroxide micro powder are also added into the raw materials of the castable containing the nano magnesium aluminate spinel, nano magnesium carbonate powder is water-based magnesium carbonate powder of which the granularity is less than 100nm, and the chemical component MgCO3 is greater than 98.0%; the nano aluminum hydroxide powder is powder with the particle size of less than 100nm, and the chemical component Al (OH) 3 of greater than 99.0%. The problem that nano powder is not easy to disperse is simply and efficiently solved, and the thermal shock resistance of the material can be effectively improved.
本发明属于浇注料技术领域，具体涉及一种含纳米镁铝尖晶石的浇注料。涉及的一种含纳米镁铝尖晶石的浇注料，含纳米镁铝尖晶石浇注料的原料包含有电熔白刚玉或烧结板状刚玉骨料和细粉、电熔或烧结镁铝尖晶石细粉、活性α‑Al2O3微粉、纯铝酸钙水泥和减水剂；其特征在于：所述的含纳米尖晶石的刚玉‑尖晶石浇注料的原料中还添加有纳米碳酸镁和纳米氢氧化铝微粉，所述纳米碳酸镁粉体为粒度小于100nm的水性碳酸镁粉体，化学成分MgCO3>98.0%；所述纳米氢氧化铝粉体为粒度小于100nm的粉体，化学成分Al(OH)3>99.0%。本简单高效的解决了纳米粉体不易分散的问题，也可有效地提高材料的抗热震性能。
