Anti-splashing environment-friendly anhydrous stemming
The invention relates to the technical field of metallurgical refractory materials, in particular to anti-splashing environment-friendly anhydrous stemming. The anti-splashing environment-friendly anhydrous stemming is prepared from high-aluminum aggregate, silicon carbide particles, coke particles, high-aluminum fine powder, nanoscale silicon carbide micropowder, nanoscale aluminum oxide powder, nanoscale graphite powder, nanoscale silicon micropowder, clay and environment-friendly resin oil. The above raw materials are stirred and mixed according to a specific ratio to prepare the novel environment-friendly anhydrous stemming with anti-splashing effect; the plasticity of the anhydrous stemming is greatly improved by subverting the grain size composition of the traditional anhydrous stemming, tap hole channels and gaps of a blast furnace wall are more easily filled when the stemming is rammed, splashing caused by discharge of in-furnace flue gas in the gaps during tapping is reduced, and micro-pores of a stemming material can be filled with nano-scale micro-powder in the material; and meanwhile, sintering of the stemming can be promoted in a high-temperature working environment, so molten iron splashing during tapping of the blast furnace can be prevented, and the strength of the stemming is also effectively improved.
本发明涉及冶金耐火材料技术领域，具体涉及一种防喷溅环保无水炮泥，原料包括高铝骨料、碳化硅颗粒、焦炭颗粒与高铝细粉、纳米级碳化硅微粉、纳米级氧化铝粉、纳米级石墨粉、纳米级硅微粉、粘土以及环保树脂油，上述原料按照特定的比例份数搅拌混合制成新的具有防喷溅效果的环保型无水炮泥，通过颠覆传统无水炮泥的粒度级配组成，使无水炮泥的塑性大大增加，打泥时更加易于填充出铁口孔道以及高炉炉壁的缝隙，减少了出铁时由于缝隙间炉内烟气排出所引起的喷溅，材料中的纳米级微粉可填充炮泥材料的微气孔，同时在高温工作环境下还可以促进炮泥的烧结，不仅能防止高炉出铁水时铁水喷溅，还有效提升了炮泥的强度。
