High-strength molten aluminum wetting resistant castable product for aluminum melting furnace and process
The invention provides a high-strength molten aluminum wetting resistant castable product for an aluminum melting furnace and a process, and belongs to the technical field of refractory materials for the aluminum melting furnace. The high-strength molten aluminum wetting-resistant castable product for the aluminum melting furnace is prepared by uniformly mixing corundum with the particle size of less than or equal to 5mm, an Al2O3-MgO-CaO multiphase material with the particle size of less than or equal to 0.074 mm, aluminum oxide micro powder with the particle size of less than or equal to 5mu m, silicon dioxide micro powder with the particle size of less than or equal to 2mu m, an anti-wetting agent, a sintering aid, a composite reinforcing agent, a composite anti-explosion agent, a binding agent and a water reducing agent. According to the invention, corundum and an Al2O3-MgO-CaO multiphase material are selected as main raw materials, and the sintering aid, the composite reinforcing agent and the composite anti-explosion agent are supplemented, so that the sintering of the components of the castable at medium temperature is promoted, and the molten aluminum wetting resistance of the castable and the physical properties of the castable under working conditions are effectively improved.
本发明提供一种熔铝炉用高强度抗铝液润湿浇注料产品及工艺，属于熔铝炉用耐火材料技术领域。本发明的耐火浇注料产品由粒径≤5mm的刚玉、粒径≤0.074mm的Al2O3‑MgO‑CaO复相材料、粒径≤5μm的氧化铝微粉、粒径≤2μm的二氧化硅微粉、抗润湿剂、助烧结剂、复合增强剂、复合防爆剂、结合剂和减水剂混合均匀，即得熔铝炉用高强度抗铝液润湿浇注料产品。本发明选择刚玉和Al2O3‑MgO‑CaO复相材料为主要原料，同时辅以助烧结剂、复合增强剂和复合防爆剂，促进浇注料各组分在中温下的烧结，有效提升了浇注料的抗铝液润湿性和工况条件下的物理性能。
