Tundish air-permeable upper nozzle, air-permeable lining material used by tundish air-permeable upper nozzle and preparation method of tundish air-permeable upper nozzle
The invention belongs to the technical field of refractory materials, and particularly relates to a tundish air-permeable upper nozzle, an air-permeable lining material used by the tundish air-permeable upper nozzle and a preparation method of the tundish air-permeable upper nozzle. The tundish air-permeable upper nozzle and the air-permeable lining material used by the tundish air-permeable upper nozzle are prepared from the following raw materials in percentage by mass: 35-50% of white corundum particles, 10-15% of white corundum fine powder, 10-15% of large flake graphite, 5-10% of zirconium mullite, 5-10% of fused quartz, 1-3% of metal silicon, 0.5-1% of boron carbide and 2-5% of urotropin and phenolic resin accounting for 8-12% of the total mass of the raw materials. And 2-4.5% of aluminum hydroxide. The tundish air-permeable upper nozzle and the air-permeable lining material used by the tundish air-permeable upper nozzle are high in porosity, good in air permeability, good in thermal shock resistance, good in erosion resistance and high in strength.
本发明属于耐火材料技术领域，具体涉及一种中间包透气上水口及其所用的透气内衬材料和制备方法。所述中间包透气上水口及其所用的透气内衬材料，由以下质量百分比的原料和占原料总质量8‑12％的酚醛树脂组成：白刚玉颗粒35‑50％，白刚玉细粉10‑15％，大鳞片石墨10‑15％，锆莫来石5‑10％，熔融石英5‑10％，金属硅1‑3％，碳化硼0.5‑1％，乌洛托品2‑5％，氢氧化铝2‑4.5％。本发明制备的中间包透气上水口及其所用的透气内衬材料，气孔率高，透气性好，热震稳定性好，抗侵蚀性能好，强度高。
