一种铝镁质耐火浇注料及其制备方法
摘要：
本发明公开了一种铝镁质耐火浇注料及其制备方法，该铝镁质耐火浇注料的组成原料按重量百分比配比为，刚玉颗粒及细粉70～80%，氧化铝微粉5～15%，含镁材料2～10%，结合剂3～8%，硅微粉0.3～1.5%，有机纤维（外加）0.05～0.1%，减水剂（外加）0.2～0.6%；该铝镁质耐火浇注料的制备方法包括配料、混料、成型、养护、干燥、储运、使用等工艺步骤；与现有技术相比，本发明铝镁浇注料具有较高的抗热震性，且成本低廉、性能优良，可用于大型钢包的包壁、包底、永久层、水口等部位，也可应用于RH浸渍管浇注料，能够适应多种工业化生产环境。
摘要（英）：

The invention discloses an aluminum-magnesium refractory castable material and a preparation method thereof. The aluminum-magnesium refractory castable material comprises the following raw materials by proportion of weight percentage: 70-80 percent of corundum granules and powder, 5-15 percent of alumina powder, 2-10 percent of magnesium-containing material, 3-8 percent of binding agent, 0.3-1.5 percent of silica micropowder, 0.05-0.1 percent of organic fibers (additional) and 0.2-0.6 percent of water reducing agent (additional). The preparation method of the aluminum-magnesium refractory castable material comprises material preparation, material mixing, formation, curing, drying, storage, transportation, use and other process steps. Compared with the prior art, the aluminum-magnesium castable material has high thermal shock resistance, low cost and excellent performance, can be applied in walls, bottoms, permanent layers, water ports and other parts of large-scale steel ladles, and can also be applied in castable materials for RH (Rockwell hardness) dip pipes. Therefore, the aluminum-magnesium castable material can adapt to a variety of industrial production environments.
