Blast furnace air supply branch pipe castable
The invention relates to a blast furnace air supply branch pipe castable. The castable comprises the following components in percentage by weight: 20%-30% of sintered mullite particles, 30%-50% of andalusite particles, 20%-35% of white corundum fine powder, 0-10% of alumina micro powder, 0-10% of high-alumina cement, 0-8% of silica powder, 0-10% of an expanding agent, 0.1%-0.5% of a water reducing agent and 0.1%-0.5% of wood fibers. The heat preservation and heat insulation performance of the material is improved through ash and air holes generated after high-temperature combustion of wood fibers, and meanwhile the high-temperature strength of the material is guaranteed.
本发明涉及一种高炉送风支管浇注料，浇注料的组分及其重量百分比为：20％～30％的烧结莫来石颗粒，30％～50％的红柱石颗粒，20％～35％的白刚玉细粉，0～10％的氧化铝微粉，0～10％的高铝水泥，0～8％的硅微粉，0～10％的膨胀剂，0.1％～0.5％的减水剂，0.1％～0.5％的木质纤维。本发明通过木质纤维高温燃烧后产生的灰份和气孔来提高材料的保温、隔热性能，同时保证材料的高温强度。
