High-purity alumina castable and preparation method thereof
The invention relates to the technical field of alumina castable, and discloses a high-purity alumina castable and a preparation method thereof. Comprising the following steps: S1, material preparation: 45-65 parts of corundum particles, 20-35 parts of corundum fine powder, 5-25 parts of light-burned spinel fine powder, 0.5-5 parts of magnesium hydroxide powder, 36 parts of fused magnesia powder, 0.33 part of calcium carbonate micro powder, 5.5-6 parts of water of a refractory castable and 0.2-2 parts of a water reducing agent are added; s2, screening, wherein the light-burned spinel fine powder is screened into fine powder through a screening device; s3, mixing and processing: firstly, uniformly stirring the screened light-burned spinel fine powder and other raw materials with relatively small particle sizes, and then pouring, vibrating and molding; according to the scheme, the structure is simple, operation is convenient and fast, fine powder can be automatically screened instead of manual work, meanwhile, large particles and fine particles in the fine powder can be distinguished, the quality and uniformity of the fine powder can be improved, and unqualified or unnecessary large particles can be recycled.
本发明涉及氧化铝浇注料技术领域，且公开了一种高纯型氧化铝浇注料及其制备方法，包括如下步骤：S1、材料准备：刚玉颗粒45‑65份、刚玉细粉20‑35份、轻烧尖晶石细粉5‑25份、氢氧化镁粉0.5‑5份、电熔氧化镁粉36份、碳酸钙微粉0.33份外加耐火浇注料5.5‑6份的水和0.2‑2份的减水剂；S2、筛分：其中对轻烧尖晶石细粉通过述筛料装置进行筛分成细粉；S3、混合加工：首先将筛分完成的轻烧尖晶石细粉与粒径较小的其他原料搅拌均匀后,浇注振动成型；本方案结构简单，操作便捷，可以代替人工自动对细粉进行筛分，同时可以将细粉中较大的颗粒与细小颗粒进行区分，通过可以提高细粉的质量和均匀性，回收不合格或不需要的大颗粒。
