Refractory material, preparation method, lining brick and hazardous waste treatment equipment
The embodiment of the invention discloses a refractory material, a preparation method, a lining brick and hazardous waste treatment equipment. The refractory material is prepared from the following raw materials in percentage by weight: 30%-60% of tabular corundum particles, 5%-20% of silicon carbide particles, 10%-30% of tabular corundum fine powder, 5%-15% of alpha-alumina micro powder, 4%-10% of submicron monatomic silicon powder and 1%-5% of metal aluminum powder. A product prepared from the refractory material for the hazardous waste disposal equipment provided by the embodiment of the invention has excellent erosion resistance, permeation resistance, wear resistance and thermal shock resistance, and the service life is prolonged from original 3-4 months to more than 12 months when the refractory material is applied to a hazardous waste incineration rotary kiln body and a secondary combustion chamber. Meanwhile, the product does not contain chromic oxide, so that pollution to the environment is avoided.
本申请实施例公开了一种耐火材料、制备方法、内衬砖和危废处置设备，其中以重量百分含量表示用于制备耐火材料的原料包括：板状刚玉颗粒30％至60％、碳化硅颗粒5％至20％、板状刚玉细粉10％至30％、ɑ‑氧化铝微粉5％至15％、亚微米级单质硅粉4％至10％、金属铝粉1％至5％。通过本申请实施例提供的危废处置设备用耐火材料得到的产品具有优良的抗侵蚀、抗渗透、耐磨性和抗热震性能，在危废焚烧回转窑窑体及二次燃烧室应用，使用寿命由原来的3～4个月提高到12个月以上。同时，产品中不含氧化铬，不会对环境产生污染。
