High-temperature ceramic wear-resistant self-flowing castable for hot-blast stove
The invention discloses a high-temperature ceramic wear-resistant self-flowing castable for a hot blast stove. The castable comprises brown fused alumina, silicon carbide, pure calcium aluminate cement, silica micro-powder, explosion-proof fibers, andalusite, calcium hexametaphosphate, PVA short fibers and fused spinel. The specially-made explosion-proof fibers and high-strength and high-elasticity PVA short fibers are added into the self-flow castable, the specially-made explosion-proof fibers are fullerene modified polypropylene fibers, and fullerene has special nanoscale spherical structure, so the fibers can endow the castable with good rapid cooling and rapid heating resistance; the high-strength and high-elasticity PVA short fibers are added, so that the castable can be remarkably endowed with good low creep property and high-temperature wear resistance; and the modified raw materials are fibrous raw materials, so that the original good self-flowing performance of the castable isnot influenced. The high-temperature ceramic wear-resistant self-flowing castable for the hot-blast stove can meet various requirements of local maintenance of refractory materials of a combustion port, a combustion branch pipe and a hot-blast short pipe of the hot-blast stove.
本发明公开了一种热风炉用高温陶瓷耐磨自流浇注料，包括以下成分：棕刚玉、碳化硅、纯铝酸钙水泥、二氧化硅微粉、防爆纤维、红柱石、六偏磷酸钙、PVA短纤维和电熔尖晶石。该自流浇注料加入了特制的防爆纤维和高强高弹PVA短纤维，其中特制的防爆纤维为富勒烯改性聚丙烯纤维，该纤维由于富勒烯的特殊纳米级球形结构，故可以赋予浇注料良好的耐急冷急热性能；而加入高强高弹PVA短纤维可以显著赋予浇注料良好的低蠕变性能和高温耐磨性能；由于改性的均为纤维状原料，故不会影响浇注料原有的良好的自流性能。本发明的热风炉用高温陶瓷耐磨自流浇注料可以满足热风炉燃烧口、燃烧支管、热风短管的耐火材料局部维修的各项要求。
