MgO-Al2O3-ZrO2 refractory brick and preparation method thereof
The invention discloses a MgO-Al2O3-ZrO2 refractory brick and a preparation method thereof, and the refractory brick contains 60-70 wt% of brine magnesia particles, 14-26 wt% of magnesium oxide fine powder, 1-7 wt% of magnesium oxide ultrafine powder and 3-15 wt% of fused zirconia corundum powder on the basis of the total mass of the refractory brick. The prepared novel MgO-Al2O3-ZrO2 refractory brick with highly dispersed ZrO2 and MgAl2O4 for the non-ferrous metal smelting furnace has excellent erosion resistance and high-temperature mechanical properties, is more suitable for being applied to the non-ferrous metal smelting industry, and can greatly prolong the service life of the non-ferrous metal smelting furnace. The invention belongs to the field of refractory materials.
本发明公开了一种MgO‑Al2O3‑ZrO2耐火砖及其制备方法，以所述耐火砖的总质量为基准，所述耐火砖含有60‑70wt％的卤水镁砂颗粒、14‑26wt％的氧化镁细粉、1‑7wt％的氧化镁超细粉、3‑15wt％的电熔锆刚玉粉末。本发明制得的具有高度分散的ZrO2与MgAl2O4的有色金属冶炼炉用新型MgO‑Al2O3‑ZrO2耐火砖具有优异的抗侵蚀性及高温力学性能，更适用于应用到有色金属冶炼产业，可以大大提高有色金属冶炼炉的寿命。本发明属于耐火材料领域。
