Stone castable for kiln and preparation method thereof
The invention relates to a stone castable for kiln. The stone castable is prepared from the following raw materials in parts by weight: 50-60 parts of white corundum, 3-6 parts of fused mullite, 10-15parts of sintered magnesia, 1-4 parts of andalusite, 2-5 parts of zirconium zinc silicate powder, 1-3 parts of nano silicon carbide, 20-30 parts of calcium aluminate cement, 3-8 parts of permanent clay, 0.5-1.5 parts of composite rare earth oxide and 0.5-1 part of a water reducing agent. According to the castable produced by the invention, substances such as white corundum, sintered magnesia, andalusite, zinc zirconium silicate powder, nano silicon carbide, composite rare earth oxide and the like are innovatively introduced and can generate a synergistic effect, so that the organization structure of the castable is changed, the volume density of the castable is improved, and the production cost is reduced. In addition, a good improvement effect is achieved on parameters such as compression resistance/fracture resistance; meanwhile, according to the preparation method disclosed by the invention, the performance of the castable is further improved by reasonable baking conditions.
本发明涉及一种窑炉用石质浇注料，以重量份计，包括以下原料：白刚玉50‑60份，电熔莫来石3‑6份，烧结镁砂10‑15份，红柱石1‑4份，硅酸锌锆粉2‑5份，纳米碳化硅1‑3份，铝酸钙水泥20‑30份，永吉黏土3‑8份，复合稀土氧化物0.5‑1.5份，减水剂0.5‑1份。本发明生产的浇注料通过创新地引入取白刚玉、烧结镁砂、红柱石、硅酸锌锆粉、纳米碳化硅、复合稀土氧化物等物质，这些物质可产生协同增效的作用，不仅改变浇注料的组织结构，提升其体积密度，而且还对抗压/抗折等参数有着良好的改善作用；同时，本发明涉及的制备方法中通过合理设置烘烤条件，进一步改改善浇注料的性能。
