Tundish castable and preparation method thereof
The invention relates to the technical field of castables for tundishes and particularly relates to a tundish castable and a preparation method thereof. The tundish castable is prepared from the following components in percentage by mass: 70 percent to 85 percent of bauxite aggregate, 1 percent to 6 percent of mullite, 4 percent to 6 percent of aluminum oxide micro powder, 2 percent to 3 percent of silicon micro powder, 2 percent to 3 percent of cement, 2 percent to 3 percent of magnesia carbon bricks, 0.1 percent to 0.15 percent of additives and the balance of water. According to the tundishcastable provided by the invention, the alpha alumina micro powder, the magnesia carbon bricks and the like are added, and meanwhile, bauxite aggregates with different component ratios and different particle size gradients are mobilized, so that the castable is more uniformly mixed, the melting point and the boiling point of the castable are greatly increased by the alpha alumina micro powder, andthe heat resistance of the castable is enhanced; the magnesia carbon brick can increase the fusion degree of all the components of the castable and improve the viscosity of the castable and the tundish, and the thermal expansion coefficient is small, so that the tundish castable is not prone to chapping.
本发明涉及中间包用浇注料技术领域，尤其涉及一种中间包浇注料及其制备方法，所述中间包浇注料包括如下组分，各组分质量百分比为：铝矾土骨料70‑85％、莫来石1‑6％、氧化铝微粉4‑6％、硅微粉2‑3％、水泥2‑3％、镁碳砖2‑3％、外加剂0.1‑0.15％、余量为水。本发明提出的中间包浇注料通过添加α氧化铝微粉、和镁碳砖等，同时调动各组分配比，不同粒径梯度的铝矾土骨料，使得浇注料混合更为均匀，α氧化铝微粉大大增加了浇注料的熔点与沸点，增强浇注料的抗热性能；镁碳砖能够增加浇注料各组分间的融合度，提升浇注料与中间包的黏性，并且热膨胀系数小，使得中间包浇注料不易皴裂。
