Refractory material of light launder for conveying molten aluminum and preparation and pouring method of refractory material
The invention discloses a refractory material of a light launder for conveying molten aluminum and a preparation and pouring method of the refractory material. The refractory material comprises a dry material and a binding agent, the dry material is prepared from the following components in percentage by mass: 50.0 to 70.0 percent of aluminum oxide hollow spheres, 5.0 to 15.0 percent of glass hollow microspheres, 5.0 to 15.0 percent of graphite fiber powder, 5.0 to 15.0 percent of alpha-Al2O3 micro powder, 5.0 to 10.0 percent of calcium aluminate cement and 1.0 to 5.0 percent of sintering agent; the binding agent is formed by mixing aluminum dihydrogen phosphate and water. The refractory material provided by the invention is a refractory castable based on phosphate combined with aluminum oxide hollow spheres, the lightweight launder for conveying molten aluminum is obtained after stirring, mixing, forming and sintering, and the lightweight launder for conveying molten aluminum has the advantages of no aluminum adhesion, light weight, excellent thermal insulation performance, high medium-temperature strength, low impurity content and the like; the prepared light launder for conveying the molten aluminum has important significance on temperature control and product quality stability in the aluminum product production process.
本发明公开了一种铝液输送用轻质流槽的耐火材料及其制备与浇注方法；所述的耐火材料包括：干料和结合剂；所述的干料包括如下质量分数的组分：氧化铝空心球50.0～70.0％、玻璃空心微珠5.0～15.0％、石墨纤维粉5.0～15.0％、α‑Al2O3微粉5.0～15.0％、铝酸钙水泥5.0～10.0％以及烧结剂1.0～5.0％；所述的结合剂由磷酸二氢铝和水混合而成。本发明提供的耐火材料是一种磷酸盐结合氧化铝空心球基的耐火浇注料，经过搅拌混合、成型、烧成后，得到铝液输送用的轻质流槽，该铝液输送用轻质流槽具有不粘铝、质轻、保温性能优良、中温强度高、杂质含量少等优点，制备的铝液输送用轻质流槽对铝产品生产过程的温度控制和产品质量稳定具有重要意义。
