Anti-splashing anhydrous stemming for blast furnace and preparation method of anti-splashing anhydrous stemming
The invention relates to the technical field of anhydrous stemming, and discloses anti-splashing anhydrous stemming for a blast furnace and a preparation method of the anti-splashing anhydrous stemming. The anti-splashing anhydrous stemming for the blast furnace comprises the following raw materials in parts by weight: 20-30 parts of aggregate, 10-20 parts of silicon carbide, 5-10 parts of white mud, 5-15 parts of a composite carbon material, 5-10 parts of kyanite, 2-5 parts of metal silicon, 0.2-0.6 part of boron carbide and 10-15 parts of an environment-friendly binding agent, the aggregate is a mixture of homogenized alumina and pyrophyllite in a mass ratio of (1.5-3): 1. The anti-splashing anhydrous stemming for the blast furnace is high in content of Al2O3 and SiC + C, and has the advantages of being large in volume density, high in compression strength, low in heating permanent linear change rate and excellent in anti-splashing performance.
本申请涉及无水炮泥的技术领域，公开了一种高炉用防喷溅无水炮泥及其制备方法。所述高炉用防喷溅无水炮泥包括以下重量份的原料：骨料20‑30份、碳化硅10‑20份、白泥5‑10份、复合碳素材料5‑15份、蓝晶石5‑10份、金属硅2‑5份、碳化硼0.2‑0.6份、环保结合剂10‑15份；所述骨料为质量比为(1.5‑3):1的均化矾土和叶腊石的混合物。本申请中的高炉用防喷溅无水炮泥中Al2O3和SiC+C含量高，并且具有体积密度大、耐压强度高、加热永久线变化率低、防喷溅性能优良的优点。
