Silica sol and chrome corundum unfired material for hazardous waste rotary kiln
Belonging to the technical field of refractory materials, the invention discloses a silica sol combined chrome corundum baking-free material for hazardous waste rotary kilns, the silica sol combined chrome corundum baking-free material is composed of the following components by mass: 2-5% of TiO2 powder, 5-10% of chromic oxide particles, 3-7% of 92 silica fume, 4-8% of C11 cement, 5-10% of silica sol, 3-5% of magnesia, and 3-5% of composite fiber. The balance is composite corundum powder; the composite corundum powder is composed of brown fused alumina coarse grains and white fused alumina micro powder, and the mass ratio of the brown fused alumina coarse grains to the white fused alumina micro powder is 2: 1. The silica sol combined chrome corundum baking-free material has the advantages of good wear resistance, long service life, good corrosion resistance, good thermal shock resistance and good high temperature resistance.
本发明公开了一种危废回转窑用硅溶胶结合铬刚玉免烧材料，属于耐火材料技术领域，所述硅溶胶结合铬刚玉免烧材料由以下质量百分比的成分组成：2‑5％TiO2粉末、5‑10％氧化铬微粒、3‑7％92硅灰、4‑8％C11水泥、5‑10％硅溶胶、3‑5％镁砂、3‑5％复合纤维，余量为复合刚玉粉；所述复合刚玉粉由棕刚玉粗粒、白刚玉微粉组成，所述棕刚玉粗粒、白刚玉微粉的质量比为：2:1，本发明的硅溶胶结合铬刚玉免烧材料具有良好的耐磨性，使用寿命长，耐腐蚀性能、抗热震性能、耐高温性能均比较好。
