摘　　要：上海梅山钢铁股份有限公司炼钢厂对影响转炉动力学条件的氧枪喷头参数和影响底吹寿命的溅渣工艺、底吹流量参数进行了优化,实现了顶底复吹同步,促进了熔池内的化学反应速度的提高,转炉终点碳氧积稳定控制在0.003 0以下,转炉的各项指标也有较好的提升。In Meishan Steelmaking Plant such a few factors affecting the kinetics condi- tions of converter as oxygen lance nozzle parameters, bottom blow life depending slag splash process and bottom blow rate parameters are optimized and thus synchronization of top blow and bottom blow is realized in the top-bottom combined blown process and the chemical reaction rate in the bath is promoted. As the results the end point carbon- oxygen equilibrium in the converter are steadily kept in the range of less than 0. 003 0 and all indicators for the converter are raised to a better level.
