Anhydrous stemming and preparation method thereof
The invention discloses anhydrous stemming which comprises the following raw materials in parts by weight: 15-35 parts of lightweight refractory aggregate; 0-25 parts by weight of an aluminum-containing aggregate; 5-10 parts by weight of coke; 10-20 parts by weight of silicon carbide; 10-30 parts by weight of ferro-silicon nitride; 3-10 parts by weight of alumina fine powder; 2-10 parts by weight of Guangxi white mud; 2-6 parts by weight of modified high-temperature asphalt; 8-15 parts by weight of an additive; in addition, 12-18 parts by weight of a binding agent is additionally added. The invention further provides a preparation method of the anhydrous stemming. The anhydrous stemming provided by the invention has good air permeability and good strength, the volume density is reduced, the weight of stemming with the same volume as that of a blast furnace tapping hole channel and the weight of stemming added with light-weight refractory aggregate are less, and the consumption of the anhydrous stemming per unit iron amount can be reduced.
本申请公开了一种无水炮泥，包括以下重量份的原料：轻量化耐火骨料15‑35重量份；含铝骨料0‑25重量份；焦炭5‑10重量份；碳化硅10‑20重量份；氮化硅铁10‑30重量份；矾土细粉3‑10重量份；广西白泥2‑10重量份；改质高温沥青2‑6重量份；添加剂8‑15重量份；并且，还外加结合剂12‑18重量份。本申请还提供上述无水炮泥的制备方法。本申请提供的无水炮泥，具有很好的透气性同时保持良好的强度，并且体积密度降低，高炉打进铁口孔道相同体积的炮泥，添加轻量化耐火骨料的炮泥重量更少，可以降低单位铁量无水炮泥消耗量。
