Low-cost tundish dry material and preparation method thereof
The invention relates to the technical field of tundishes, in particular to a low-cost tundish dry material and a preparation method thereof. The low-cost tundish dry material comprises the following raw materials in parts by weight: 2-20 parts of olive sand; 2-5 parts of dead burned magnesia; 0.5 to 3 parts of a binding agent; and 0.5 to 3 parts of T-L011. The olive sand grain composition is as follows: 1-3 parts of olive sand with the particle size of more than 0 mm and less than or equal to 1 mm, 2-4 parts of olive sand with the particle size of more than 1 mm and less than or equal to 3 mm, and 2-5 parts of olive sand with the particle size of more than 3 mm and less than or equal to 5 mm. 80 dead burned magnesia fine powder is adopted as the dead burned magnesia, and the particle size is 200 meshes. The binding agent is phenolic resin, and the weight part of the phenolic resin is 1-2 parts. The weight part of the T-L011 is 1-2 parts. The low-cost tundish dry material has high oxidation resistance, thermal shock resistance and low thermal conductivity, and has the advantages that the service life is prolonged, the production cost is reduced, the molding is fast, and replacement is relatively easy.
本发明涉及中间包技术领域，尤其涉及一种低成本中间包干式料及其制备方法。一种低成本中间包干式料，包括以下重量份的原料：橄榄砂2～20份；重烧镁砂2～5份；结合剂0.5～3份；T‑L011 0.5～3份。所述橄榄砂颗粒级配是：0mm＜粒度≤1mm的橄榄砂1～3份、1mm＜粒度≤3mm的的橄榄砂2～4份、3mm＜粒度≤5mm的橄榄砂2～5份。所述重烧镁砂采用80重烧镁砂细粉，粒级为200目。所述结合剂采用酚醛树脂，酚醛树脂的重量份为1～2份。所述T‑L011的重量份为1～2份。本发明具有良好的抗氧化性、抗热震性、低导热性，具有增加使用寿命，降低生产成本，成型快，更换相对容易的优点。
