Aluminum-chromium-zirconium-silicon composite brick for zinc oxide rotary kiln reaction zone, and preparation method
The invention discloses an aluminum-chromium-zirconium-silicon composite brick for a reaction zone of a zinc oxide rotary kiln. The aluminum-chromium-zirconium-silicon composite brick comprises the following raw materials in parts by weight: 40-78 parts of tabular corundum; 10-21 parts of fused chromium aluminate spinel; 3-7 parts of silicon carbide; 9-18 parts of silicon carbide; 2-8 parts of zirconium oxide powder; 2-6 parts of alumina ultrafine powder; and 3-6 parts of a binder. According to the invention, by doping tabular corundum with fused chromium aluminate spinel, silicon carbide, silicon carbide, zirconia powder, alumina ultrafine powder and a binder according to the optimized ratio, the energy-saving aluminum-chromium-zirconium-silicon composite brick which is suitable for a zinc oxide rotary kiln and has the advantages of low heat conductivity coefficient, small volume density and strong corrosion resistance is prepared by adopting the sustainable closest packing density particle grading, so that the unit energy consumption of the zinc oxide rotary kiln is effectively reduced, the service life of masonry refractory bricks of the zinc oxide rotary kiln is prolonged, themaintenance cost of the rotary kiln is greatly reduced, and the production efficiency of zinc oxide is improved.
本发明公布了一种氧化锌回转窑反应带用铝铬锆硅复合砖，包括如下原料：板状刚玉40‑78的重量份；电熔铬铝尖晶石10‑21的重量份；碳化硅3‑7的重量份；碳化硅9‑18的重量份；氧化锆粉2‑8的重量份；氧化铝超细粉2‑6的重量份；粘结剂3‑6的重量份。本发明通过板状刚玉掺和电熔铬铝尖晶石、碳化硅、碳化硅、氧化锆粉、氧化铝超细粉、粘结剂的优化配比，采用可续的最紧密堆积密度颗粒配级，制得适合氧化锌回转窑用的具有导热系数低、体积密度小、抗腐蚀能力强的节能型铝铬锆硅复合砖，有效降低氧化锌回转窑单位能耗，提升氧化锌回转窑的砌筑耐火砖的使用寿命，大大降低了回转窑的维护成本，提升氧化锌的生产效率。
