摘　　要：基于有关钢包的引流技术,研究了石英质、镁橄榄石质和铬铁矿质引流材料在不同石墨和铬铁矿加入量条件下的流动性能、烧结性能和热膨胀性能。结果表明,石英砂加4%石墨混合物的流动性好;一定量的石英砂、铬铁矿、石墨的混合物可以提高材料的流动性能和获得恰当的烧结性能;加入钾长石粉优化了引流砂的烧结性能和热膨胀性能。The flowability, sintering performance and dilatability of silica sands, olivine sands and chromite sands are studied based on laboratory and plant experiments of the slide gate packing tech- nology. According to the result of our experiments, silica sands added with 4wt% graphite powders has excellent fluidity, and the right amount of silica mixed with chromite and graphite powders can improve the flowability and sintering performance of the stuffing sands. The sintering performance and dilatability of the stuffing sands added with some feldspar powders are better than that without the feldspar powders.
