Low-aluminum-magnesium composite unburned brick and preparation method thereof
The invention provides a low-aluminum-magnesium composite unburned brick. The low-aluminum-magnesium composite unburned brick is prepared from the following raw materials in parts by weight: 25-30 parts of 0-1mm fused magnesite, 20-25 parts of 1-3mm fused magnesite, 10-15 parts of 3-5mm fused magnesite, 24-31 parts of high-purity magnesite 200-mesh fine powder, 20-30 parts of light calcined dolomite powder, 10-15 parts of magnesite powder, 3-5 parts of 1mm-3mm fused magnesia-alumina spinel, 1-3 parts of powdery boric acid, 1-3 parts of hercynite fine powder, 1-3 parts of zinc-alumina spinel fine powder, 2-4 parts of alpha-Al2O3 superfine powder, 2-4 parts of tungsten carbide powder and 2-4 parts of a binding agent. The unburned brick produced by the invention replaces sintered magnesite bricks, high-purity magnesite bricks and magnesite-alumina bricks, is used for lime kilns and cement kilns, has the advantages of high temperature resistance, low thermal conductivity, hydration resistance, particularly high thermal shock stability and good heat-insulating property, and effectively prolongs the service life.
本发明提供了一种低铝镁质复合不烧砖，是由下列重量份数的原料制备而成：0～1mm电熔镁砂25‑30份、1mm～3mm电熔镁砂20‑25份、3mm～5mm电熔镁砂10‑15份、高纯镁砂200目细粉24‑31份、轻烧白云石粉20‑30份、菱镁石粉10‑15份；1mm～3mm的电熔镁铝尖晶石3‑5份、粉末状硼酸1‑3份、铁铝尖晶石细粉1‑3份、锌铝尖晶石细粉1‑3份、α‑AlO超微粉2‑4份、碳化钨粉2‑4份；结合剂：2‑4份。本发明生产的不烧砖，代替烧成镁砖、高纯镁砖、镁铝砖，用于石灰窑、水泥窑，具有耐高温、低导热、抗水化、特别高的热震稳定性、隔热性能良好的优点，有效增加使用寿命。
