Composite refractory mortar for building secondary lead smelting furnace and preparation method of composite refractory mortar
The invention belongs to the technical field of refractory materials, and discloses a composite refractory mortar for building a secondary lead smelting furnace, which is mainly prepared from the following raw materials in percentage by mass: 70-74% of white corundum powder, 8-12% of chromium oxide green powder, 3-6% of a-Al2O3 micro powder, 3-5% of fused zirconia powder, 5-8% of high-purity mullite powder, and a binding agent and a dispersing agent which respectively account for 2% of the total weight of the raw materials. In the composite refractory mortar, Al2O3 is greater than or equal to 78%, Cr2O3 is greater than or equal to 8.0%, ZrO2 + HfO2 is greater than or equal to 2.8%, and SiO2 is less than or equal to 5%. As the raw materials are high in purity and low in impurity content, the obtained aluminum-chromium-zirconium-mullite composite refractory mortar product has excellent thermal shock resistance and erosion resistance, and the service life of a masonry body is effectively prolonged when the aluminum-chromium-zirconium-mullite composite refractory mortar product is matched with a refractory brick made of the same material for use.
本发明属于耐火材料技术领域，公开了一种再生铅冶炼炉砌筑用复合耐火泥，主要由以下质量百分比的原料制备而成：白刚玉粉70~74%，氧化铬绿粉8~12%，a‑Al2O3微粉3~6%，电熔氧化锆粉3~5%，高纯莫来石粉5~8%，并加入分别占上述总重量2%的结合剂和分散剂；所述复合耐火泥中Al2O3≥78%、Cr2O3≥8.0%、ZrO2+HfO2≥2.8%、SiO2≤5%。本发明由于原料纯度高，杂质含量少，所得铝铬锆莫来石复合耐火泥制品具有优良的热震稳定性能以及抗侵蚀性能，与同材质耐火砖配套使用，有效延长了砌筑体的使用寿命。
