Calcium dialuminate-containing chrome corundum castable for hazardous waste incineration device
The invention belongs to a refractory material technology for a hazardous waste incineration device, and relates to a chromium corundum castable containing calcium dialuminate for the hazardous waste incineration device. The chromium corundum castable containing calcium dialuminate comprises the following raw materials in percentage by mass: 5 to 30 percent of calcium dialuminate, 60 to 85 percent of chromium corundum, 3 to 8 percent of active alpha-Al2O3 micro powder, 1 to 5 percent of chromium oxide green, 3 to 10 percent of pure calcium aluminate cement and 0.1 to 0.2 percent of a water reducing agent, wherein the water reducing agent is additionally added. The chromium corundum castable containing calcium dialuminate prepared by the invention has the characteristics of excellent mechanical property, good thermal shock resistance, low heat conductivity coefficient (the heat conductivity coefficient at 1000 DEG C is not more than 2W/mK), good acid and alkali gas erosion resistance at high temperature, good volume stability, long service life and the like, and is an environment-friendly refractory material with excellent performance.
本发明属于危险废弃物焚烧装置用耐火材料技术，涉及一种危险废弃物焚烧装置用含二铝酸钙的铬刚玉浇注料。涉及的一种含二铝酸钙的铬刚玉浇注料的原料及质量百分比为：二铝酸钙5‑30%、铬刚玉60‑85%、活性ɑ‑Al2O3微粉3‑8%、氧化铬绿1~5%、纯铝酸钙水泥3‑10%、减水剂0.1‑0.2%，其中所述的减水剂为外加。本发明制备的含二铝酸钙的铬刚玉浇注料具有力学性能优异、抗热震性能好、导热系数低（1000℃下的导热系数不超过2W/mK）、高温下抗酸碱性气体侵蚀性能好、体积稳定性好、使用寿命长等特点，是一种性能优异的环保型耐火材料。
