Magnesium-aluminum-chromium unburned brick applied to high-temperature shaft kiln and preparation method of magnesium-aluminum-chromium unburned brick
The invention discloses a magnesium-aluminum-chromium unburned brick applied to a high-temperature shaft kiln. The formula comprises the following raw materials in parts by weight: 10 to 15 parts of fused magnesia-alumina spinel with a particle size of 1 to 3 mm; 20-25 parts of 98 fused magnesite with the particle size of 0-1 mm, 15-20 parts of 98 fused magnesite with the particle size of 1-3 mm,10-15 parts of 98 fused magnesite with the particle size of 3-5 mm, 22-29 parts of 98 fused magnesite 200-mesh fine powder, 20-30 parts of light calcined dolomite powder and 10-15 parts of magnesite powder; 1-3 parts of hercynite 200-mesh fine powder, 1-3 parts of powdery boric acid, 5-10 parts of Pakistan chromium ore superfine powder; 2-4 parts of zirconium oxide, and 2-4 parts of a binding agent. The unburned brick produced by the invention replaces sintered magnesite-chrome bricks, high-purity magnesite bricks and magnesite-aluminum bricks, is used for a high-temperature shaft kiln, prolongs the service life, and has the advantages of high temperature resistance, wear resistance, stripping resistance, particularly high thermal shock stability and good heat-insulating property.
一种应用于高温竖窑的镁铝铬质不烧砖，包括以下重量份数的原料：1mm～3mm的电熔镁铝尖晶石10‑15份、0～1mm的98电熔镁砂20‑25份、1mm～3mm的98电熔镁砂15‑20份、3mm～5mm的98电熔镁砂10‑15份、98电熔镁砂200目细粉22‑29份、轻烧白云石粉20‑30份、菱镁石粉10‑15份；铁铝尖晶石200目细粉1‑3份，粉末状硼酸1‑3份、巴基斯坦铬矿超微粉5‑10份、氧化锆：2‑4份；结合剂：2‑4份。本发明生产的不烧砖，代替烧成镁铬砖、高纯镁砖、镁铝砖，用于高温竖窑，增加使用寿命，具有耐高温、耐磨损、抗剥落、特别高的热震稳定性、隔热性能良好的优点。
