Anti-splashing stemming material for blast furnace and preparation method of anti-splashing stemming material
The invention discloses a stemming material for an anti-splashing blast furnace and a preparation method of the stemming material, the stemming material comprises a certain amount of high-alumina bauxite particles, coke particles, silicon carbide fine powder, clay fine powder, quartz sand fine powder, ferro-silicon nitride fine powder, high-temperature asphalt and tar, and the high-alumina bauxite particles are equal-diameter particles. The method comprises the following steps: by taking high bauxite particles and coke particles as aggregates and silicon carbide fine powder, clay fine powder, quartz sand fine powder, ferro-silicon nitride fine powder and high-temperature asphalt as matrix materials, firstly premixing the matrix materials, then putting the matrix materials and the aggregates into a preheated mixing mill for mixing, then adding tar, continuously mixing and rolling, and carrying out extrusion molding by adopting a mud extruding machine, so as to obtain a finished product. The anti-splashing stemming material for the blast furnace is obtained. The stemming material is good in uniformity and air permeability, high in gap filling capacity, excellent in anti-splashing performance and good in slag resistance. The method has the advantages of being convenient to operate, low in labor intensity, high in production efficiency and low in cost.
本发明公开了一种防喷溅高炉用炮泥材料及其制备方法，本炮泥材料组分包括一定量的高铝矾土颗粒、焦炭颗粒、碳化硅细粉、粘土细粉、石英砂细粉、氮化硅铁细粉、高温沥青以及焦油，其中高铝矾土颗粒为等径颗粒。本方法以高铝矾土颗粒和焦炭颗粒为骨料，以碳化硅细粉、粘土细粉、石英砂细粉、氮化硅铁细粉、高温沥青为基质料，先将基质料预混，再将基质料和骨料置于预先加热的混碾机中混合，然后加入焦油并继续混合、碾压，采用挤泥机挤出成型，得到防喷溅高炉用炮泥材料。本炮泥材料均匀性和透气性好、缝隙填充能力强、防喷溅性能优异和抗渣性能良好，本方法具有操作方便，劳动强度低，生产效率高和成本低的优点。
