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。
