Phase change toughened mullite silicon carbide castable and preparation method thereof
The invention relates to a phase change toughened mullite silicon carbide castable. The mullite-silicon carbide castable is prepared from the following components in parts by mass: 40-60 parts by mass of mullite, 10-25 parts by mass of fused alumina zirconia, 10-20 parts by mass of silicon carbide, 2-5 parts by mass of silica powder, 5-10 parts by mass of calcined alumina powder and 2-5 parts by mass of calcium aluminate cement, wherein each 100 parts by mass of the mullite-silicon carbide castable is prepared from the following raw materials in parts by mass: 40-60 parts by mass of mullite, 10-25 parts by mass of fused alumina zirconia, 10-20 parts by mass of silicon carbide, 2-5 parts by mass of calcined alumina powder and 2-5 parts by mass of calcium aluminate cement. A burning promoting agent accounting for 0.1-0.3 wt% of the raw materials and a water reducing agent accounting for 0.1-0.3 wt% of the raw materials are used as additives. The phase-change toughened mullite silicon carbide castable and the preparation method thereof have the advantages that performance reduction caused by easy oxidation of a mullite silicon carbide refractory material is reduced, the thermal shock resistance of the refractory material is remarkably improved, and the phase-change toughened mullite silicon carbide castable is suitable for steel ladle linings, blast furnace bottoms, molten iron tanks and the like. And the damaged part of the mullite silicon carbide brick can be repaired.
一种相变增韧的莫来石碳化硅浇注料，其特征在于，由以下质量份的各组分制成：每100质量份的所述莫来石碳化硅浇注料以40‑60质量份的莫来石、10‑25质量份的锆刚玉、10‑20质量份的碳化硅、2‑5质量份的硅微粉、5‑10质量份的煅烧氧化铝粉和2‑5质量份的铝酸钙水泥为原料，以所述原料0.1‑0.3wt%的促烧剂和0.1‑0.3wt%的减水剂为添加剂。本发明的相变增韧的莫来石碳化硅浇注料及其制备方法具有减少莫来石碳化硅质耐火材料易氧化带来的性能下降，显著改善耐火材料的抗热震性能，适用于盛钢桶内衬，高炉炉底、铁水槽，转炉出钢口等部位以及修补莫来石碳化硅砖的破损部位的优点。
