Non-clay combined anhydrous stemming for large blast furnace and manufacturing method of non-clay combined anhydrous stemming
The invention discloses non-clay bonded anhydrous stemming for a large blast furnace and a manufacturing method thereof. The stemming is prepared from the following raw material components in percentage by weight: 30-50% of refractory aggregate, 5-15% of coke powder, 5-15% of silicon carbide, 10-20% of ferro-silicon nitride, 1-8% of asphalt, 10-20% of composite superfine powder, 0-2% of a metal additive and 8-15% of a liquid binder. The preparation method comprises the steps of burdening, mixing and grinding, forming, packaging and the like. According to the stemming, clay is not used in the stemming, the adverse effect of the clay on the stemming is avoided, a certain amount of composite superfine powder is added to enable the stemming to generate plasticity, the construction performance of the stemming is met, meanwhile, the environment-friendly performance, the slag iron corrosion resistance and the like of the stemming are improved, and the stemming has good application prospects. Therefore, the increasingly harsh requirements of the refractory material for the taphole of the large blast furnace are met.
本发明公开了一种大型高炉用非粘土结合无水炮泥及其制造方法，炮泥由以下重量百分比的原料组分制备而成：30～50％耐火骨料，5～15％焦粉，5～15％碳化硅，10～20％氮化硅铁，1～8％沥青，10～20％复合超微粉，0～2％金属添加剂和8～15％的液态结合剂。经配料、混碾、成型、包装等步骤精制而成。本发明在炮泥中完全不使用粘土，避免了粘土对炮泥的不利影响，通过添加一定量的复合超微粉来使炮泥产生可塑性，满足炮泥的施工性能，同时提高了炮泥的环保性能、抗渣铁侵蚀性能等，从而满足大型高炉出铁口耐火材料的日益苛刻的要求。
