Blast furnace tapping channel refractory castable and preparation method thereof
The invention discloses a refractory castable for a blast furnace tapping channel. The refractory castable comprises a main material and an additive, the main materials comprise the following raw materials in percentage by mass: 60%-75% of corundum, 10%-30% of silicon carbide, 2%-6% of alpha-Al2O3 micro powder, 1%-5% of SiO2 micro powder, 1%-4% of calcium aluminate cement, 0.5%-1% of monatomic silicon powder and 0.5%-1.5% of spherical asphalt; the additive comprises modified carbon fibers and a water reducing agent. The invention also discloses a preparation method of the blast furnace tapping channel refractory castable. The refractory castable for the blast furnace tapping channel has excellent high-temperature-resistant mechanical property, thermal shock resistance and erosion resistance, the service life of the castable can be effectively prolonged, and the production efficiency of cast iron is improved.
本发明公开了一种高炉出铁沟耐火浇注料，包括主料和外加剂；主料包括下述质量百分比的原料：刚玉60％‑75％、碳化硅10％‑30％、α‑Al2O3微粉2％‑6％、SiO2微粉1％‑5％、铝酸钙水泥1％‑4％、单质硅粉0.5％‑1％、球状沥青0.5％‑1.5％；外加剂包括改性碳纤维和减水剂。本发明还公开了上述高炉出铁沟耐火浇注料的制备方法。本发明的高炉出铁沟耐火浇注料具有优良的耐高温力学性能、抗热震和抗侵蚀性能，能有效延长浇注料的使用寿命，提高铸铁生产效率。
