Light-weight refractory castable for blast furnace swing chute and preparation method thereof
The invention provides a light-weight refractory castable for a blast furnace swing chute. The light-weight refractory castable comprises the following components in parts by weight: 50-65 parts of microporous corundum particles, 10-15 parts of corundum particles, 10-15 parts of silicon carbide, 1-3 parts of cement, 1-3 parts of silica powder, 1-3 parts of carbon black, 6-10 parts of activated alumina micro powder, 1-3 parts of an antioxidant, 1-3 parts of a composite anti-explosion agent and 0.1-0.3 parts of a water reducing agent. The microporous corundum particles, the corundum particles, the silicon carbide, the cement, the silica powder, the carbon black, the activated alumina micro powder, the antioxidant, the composite anti-explosion agent and the water reducing agent are put into a stirrer and stirred for 10-15 min, and the light-weight refractory castable for the blast furnace swing chute is obtained after uniform mixing. The obtained light-weight refractory castable product for the blast furnace swing chute is small in volume density, low in apparent porosity, high in closed porosity, small in heat conductivity coefficient and high in slag erosion resistance.
本发明提供了一种轻量化高炉摆动溜槽用耐火浇注料，其组成按重量份数计如下：微孔刚玉颗粒50～65份，刚玉颗粒10～15份，碳化硅10～15份，水泥1～3份，硅微粉1～3份，碳黑1～3份，活性氧化铝微粉6～10份，抗氧化剂1～3份，复合防爆剂1～3份，减水剂0.1～0.3份。将微孔刚玉颗粒、刚玉颗粒、碳化硅、水泥、硅微粉、碳黑、活性氧化铝微粉、抗氧化剂、复合防爆剂、减水剂投入到搅拌机中搅拌10～15min，混合均匀即得轻量化高炉摆动溜槽用耐火浇注料。所得轻量化高炉摆动溜槽用耐火浇注料产品体积密度小、显气孔率低、闭口气孔率高、导热系数小、抗熔渣侵蚀能力强。
