High-alumina fiber castable
The invention discloses a high-alumina fiber castable, and the formula of the high-alumina fiber castable comprises first-grade high-alumina bauxite aggregate, second-grade high-alumina bauxite aggregate, refractory fibers, alumina powder, high-strength fibers, chromium oxide, silica fume, high-alumina cement, alumina clinker, sodium tripolyphosphate and a water reducing agent. Meanwhile, chromium oxide is added into the formula, the crystallinity of the castable is increased through the chromium oxide, the combination of the castable is tighter, the corrosion resistance of the castable is improved, and the structural strength of the castable is enhanced through the addition of aluminum oxide, steel fibers and carbon fibers; according to the castable disclosed by the invention, the phenomenon that the castable is broken and falls off due to impact and collision is avoided, the grain size uniformity of the castable is ensured by grading the aggregates and adding the aggregates with different grain sizes, the porosity of the castable is reduced, and the quality of the castable is improved.
本发明公开了高铝质纤维浇注料，配方包括：一级高铝矾土骨料、二级高铝矾土骨料、耐火纤维、氧化铝粉末、高强纤维、氧化铬、硅灰、高铝水泥、矾土熟料、三聚磷酸钠和减水剂，本发明通过将陶瓷纤维和石棉纤维作为耐火纤维添加到配方中，增强了浇注料的耐高温能力，同时配方中加入氧化铬，氧化铬增加了浇注料的结晶度，并且浇注料的结合更加紧密，有利于提升浇注料的耐腐蚀能力，通过氧化铝、钢纤维和碳纤维的加入，增强了浇注料的结构强度，避免了冲击和碰撞导致的浇注料破裂脱落的现象发生，通过对骨料进行分级，添加不同粒度的骨料，保证了浇注料的粒径均匀，降低了浇注料的孔隙率，提升了浇注料的质量。
