Long-life ladle castable and preparation method thereof
The invention belongs to the technical field of ladle castable, and discloses a long-life ladle castable which comprises the following raw materials in percentage by weight: 10-30% of flint clay or M47 mullite with the particle size of 6-3mm; 20%-40% of flint clay or M47 mullite with a particle size of 3-1 mm; 10%-30% of flint clay, M47 mullite or silicon carbide with the particle size of 1-0 mm; 10%-20% of fine powder; 5%-10% of micro powder; 5% to 10% of aluminate cement; the fine powder is composed of one or more of quartz powder, silicon carbide powder, mullite powder and bauxite powder; the micro powder is composed of one or more of silicon dioxide micro powder and nano andalusite micro powder; the raw materials at least comprise M47 mullite. The M47 mullite is used for replacing part of flint clay, so that the thermal shock resistance of the material is improved, the thermal conductivity of the material is reduced, the sintering strength of the material is improved, and the performance of the castable is more stable. The andalusite micro powder is added to replace boron carbide, so that the anti-oxidation performance of the castable is improved, and the cost of the castable is reduced.
本发明属于铁水包浇注料技术领域，公开了一种高寿命铁水包浇注料，按重量百分比计，原料包括粒径6‑3mm焦宝石或M47莫来石10％‑30％；粒径3‑1mm焦宝石或M47莫来石20％‑40％；粒径1‑0mm焦宝石、M47莫来石或碳化硅10％‑30％；细粉10％‑20％；微粉5％‑10％；铝酸盐水泥5％‑10％；细粉由石英粉、碳化硅粉、莫来石粉、铝矾土粉的一种或几种构成；微粉由二氧化硅微粉、纳米红柱石微粉的一种或几种构成；原料中至少包括M47莫来石。本发明用M47莫来石替换部分焦宝石提高材料的热震稳定性，降低材料的热导率，改善材料的烧结强度，浇注料性能更稳定。加入了红柱石微粉替代碳化硼，改善浇注料防氧化性能的同时，降低浇注料成本。
