Light energy-saving tundish permanent layer foaming castable and preparation method thereof
The invention belongs to the technical field of unshaped refractory materials, and particularly relates to a light energy-saving tundish permanent layer foaming castable and a preparation method thereof. The light energy-saving tundish permanent layer foaming castable comprises light mullite aggregate, aluminum oxide fine powder, silica powder, aluminum oxide hollow balls, mullite fibers, explosion-proof fibers, calcium aluminate cement, a water reducing agent, a dispersing agent and a foaming accelerant which are in grain composition, and liquid raw materials are water, silica sol and a foaming agent. According to the method, the light aggregate and hollow balls are adopted, foaming technology is combined, the volume density of the prepared foaming castable is only 1.0-1.4 g/cm < 3 > and is about half of the volume density (2.0-2.8 g/cm < 3 >) of a traditional low-cement self-flowing castable, and when the foaming castable is used as a tundish permanent layer, the foaming castable is light and energy-saving, the use amount of materials with the same volume is reduced by half, and the preparation cost is greatly reduced.
本发明属于不定形耐火材料技术领域，具体涉及一种轻质节能中间包永久层发泡浇注料及其制备方法。包括颗粒级配的轻质莫来石骨料、氧化铝细粉、硅微粉、氧化铝空心球、莫来石纤维、防爆纤维、铝酸钙水泥、减水剂、分散剂、发泡促进剂、另采用的液体原料为水、硅溶胶、发泡剂，本发明通过采用轻质骨料和空心球，结合采用发泡技术，制备得到的发泡浇注料的体积密度仅为1.0～1.4g/cm3，大约是传统低水泥自流浇注料的体积密度(2.0～2.8g/cm3)的一半，作为中间包永久层使用时，不仅轻质节能，而且同等体积材料用量减少一半，制备成本大幅降低。
