Chromium-zirconium-corundum composite brick for garbage incineration grate furnace
The invention relates to the technical field of refractory bricks, in particular to a chromium zirconium corundum composite brick for a garbage incineration grate furnace, which comprises the following components in parts by weight: 60-75 parts of white corundum powder, 7-14 parts of chromium sesquioxide, 12-20 parts of zirconium oxide-silicon carbide composite powder, 2-5 parts of magnesium oxide, 3-6 parts of kaolin and 1-4 parts of adhesive. The zirconium oxide-silicon carbide composite powder is prepared from the following raw materials in parts by weight: 0.8 to 2 parts of tetraethyl orthosilicate, 2.5 to 6 parts of absolute ethyl alcohol, 0.8 to 1.5 parts of nano zirconium oxide, 2 to 3 parts of cane sugar, 0.4 to 1 part of trimethoxysilane and 5.5 to 6.5 parts of deionized water. The composite brick disclosed by the invention is relatively high in density, few in internal defects, excellent in fire resistance, small in deformation in a high-temperature environment, excellent in corrosion resistance, relatively small in damage of incineration slag to the composite brick, and capable of effectively reducing the occurrence of fracture phenomena and prolonging the service life of an incinerator.
本发明涉及耐火砖技术领域，具体涉及一种垃圾焚烧炉排炉用铬锆刚玉复合砖，所述复合砖按重量份计包括以下成分：白刚玉粉60～75份、三氧化二铬7～14份、氧化锆‑碳化硅复合粉12～20份、氧化镁2～5份、高岭土3～6份、粘接剂1～4份；所述氧化锆‑碳化硅复合粉由以下重量份的原料制成：正硅酸四乙酯0.8～2份、无水乙醇2.5～6份、纳米氧化锆0.8～1.5份、蔗糖2～3份、三甲氧基硅烷0.4～1份、去离子水5.5～6.5份。本发明的复合砖致密度较高、内部缺陷少、耐火性能优异，在高温环境下变形量小，且耐腐蚀性能优异，焚烧熔渣对复合砖的损伤较小，可有效减少断裂现象的发生，提高焚烧炉的使用寿命。
