Large-granularity tabular corundum for large ladle castable
The invention discloses large-particle-size tabular corundum for a large steel ladle castable, and belongs to the technical field of fire resistance. Comprising the following raw materials: 60%-65% of tabular corundum, 10%-15% of magnesium aluminate spinel, 5%-8% of nano spinel, 10%-20% of aluminate cement, 1%-2% of magnesia-calcium sand, 1%-1.5% of reinforcing fibers and 3%-4.5% of molybdenum disilicide. According to the large-particle-size tabular corundum for the large steel ladle castable, various raw materials are mixed, on one hand, the fire resistance can be improved, reinforcing fibers are combined to improve the structural strength, damage caused by impact in the subsequent use process is avoided, and on the other hand, magnesium calcium sand and molybdenum disilicide are combined to reinforce the outer wall of a finished product, so that the service life of the finished product is prolonged. And secondly, nano spinel and magnesium aluminate spinel are utilized, so that the thermal expansion stability of the finished product is guaranteed, and damage is avoided.
本发明公开了大型钢包浇注料用大粒度板状刚玉，属于耐火技术领域，该大型钢包浇注料用大粒度板状刚玉，包括如下原料：板状刚玉60％‑65％、镁铝尖晶石10％‑15％、纳米尖晶石5％‑8％、铝酸盐水泥10％‑20％、镁钙砂1％‑2％、加强纤维1％‑1.5％与二硅化钼3％‑4.5％。该大型钢包浇注料用大粒度板状刚玉，采用多种原料混合，一方面可以提高耐火性能，其中结合加强纤维提高结构强度，避免在后续的使用过程中，因为撞击产生损毁，其次是结合镁钙砂和二硅化钼，对成品的外壁进行强化，避免铁水对成品的外壁进行磨损，提高抗磨损性能，其次是利用纳米尖晶石和镁铝尖晶石，保证成品的热膨胀稳定性，避免产生损坏。
