Iron runner castable and preparation method thereof
The invention discloses an iron runner castable and a preparation method thereof, and relates to an Al2O3-MA-SiC-C iron runner castable. The castable comprises 45%-65% of fused brown corundum, 5%-15% of fused compact corundum, 2%-6% of defective spinel, 8%-24% of silicon carbide, 1%-3% of cement, 1%-3% of silica powder, 1%-3% of carbon black, 6%-10% of activated alumina micro powder, 1%-3% of an antioxidant, 1%-3% of a composite antiknock agent and 0.1%-0.3% of a composite water reducer. The preparation method comprises the following steps: premixing defective spinel and carbon black by an airflow mill to obtain premixed powder; and uniformly stirring the premixed powder with fused brown corundum, fused compact corundum, silicon carbide, cement, silica powder, activated alumina micro powder, an antioxidant, a composite antiknock agent and a composite water reducing agent. The refractory brick has the beneficial effects of good high-temperature erosion resistance, slag iron chemical erosion resistance and thermal shock resistance stability, simple production and construction processes and long service life.
本发明一种铁沟浇注料及其制备方法涉及Al2O3‑MA‑SiC‑C质铁沟浇注料，电熔棕刚玉45％～65％，电熔致密刚玉5％～15％，缺陷尖晶石2％～6％，碳化硅8％～24％，水泥1％～3％，硅微粉1％～3％，碳黑1％～3％，活性氧化铝微粉6％～10％，抗氧化剂1％～3％，复合防爆剂1％～3％，复合减水剂0.1％～0.3％。制备方法，包括如下步骤：由气流磨对缺陷尖晶石与碳黑进行预混，获得预混合粉；将预混合粉与电熔棕刚玉、电熔致密刚玉、碳化硅、水泥、硅微粉、活性氧化铝微粉、抗氧化剂、复合防爆剂、复合减水剂搅拌均匀即可。有益效果是：具有良好的耐高温冲刷性能、耐渣铁化学侵蚀性、抗热震稳定性能，生产及施工工艺简单，使用寿命高。
