Erosion-resistant castable for continuous casting tundish and preparation method thereof
The invention relates to the technical field of refractory materials, in particular to an erosion-resistant castable for a continuous casting tundish and a preparation method. The erosion-resistant castable comprises the following components in percentage by weight: 66-75% of magnesia, 8-10% of white corundum, 5-9% of bauxite, 3-4% of bauxite spinel, 8-10% of a binding agent, 0.12-0.15% of a waterreducing agent and 1.2-1.5% of an anti-explosion agent. The invention aims to provide the erosion-resistant castable for the continuous casting tundish and the preparation method of the erosion-resistant castable. Through research and development of the erosion-resistant castable for the continuous casting tundish, the technical problems that in the prior art, alkaline slag severely erodes castables and dry materials, the thermal expansion coefficient of magnesia is large, the shock resistance is poor, and the service life of the castables is limited are solved.
本发明涉及耐火材料技术领域，尤其是涉及一种连铸中间包用耐侵蚀浇注料及制备方法。按照重量百分数数计包括：镁砂66‑75％、白刚玉8‑10％、铝矾土5‑9％、铝矾土尖晶石3‑4％、结合剂8‑10％、减水剂0.12‑0.15％、及防爆剂1.2‑1.5％。本发明的目的在于提供一种连铸中间包用耐侵蚀浇注料及制备方法，通过连铸中间包用耐侵蚀浇注料的研发以解决现有技术中存在的碱性渣对浇注料和干式料的侵蚀严重，氧化镁热膨胀系数大，抗震性差，限制了浇注料的使用寿命的技术问题。
