摘要
莱钢2×1880m3高炉采用粒煤喷吹新技术,针对粒煤平均粒度大、输送难度高的情况,进行喷吹工艺研究,提高了粒煤输送固气比,实现了降低喷吹成本的目标。
A new granular coal injection technology was adopted for Laigang 2 × 1880-m3 BF. Aimed at the situation of larger average grain size and greater difficulty in conveying, injection process was researched o11, thus increasing solid-gas rate of granular coal and achieving the goal of reducing injection cost.
