摘　　要：利用Fluent软件对电炉炼钢中两种常用氧枪,聚合射流氧枪和普通超音速氧枪进行了射流特性的数值模拟,分析了保护气位置、射流角度及压强对聚合射流氧枪射流特性的影响,并在天津钢铁集团公司110 t电炉进行了生产实践。结果表明,使用聚合射流氧枪后电炉冶炼效果改善,平均冶炼周期缩短10～15 min,各项消耗指标改善。The jet-flow behavior of two frequently used oxygen lances, namely the clus- ter oxygen lance and the common super sonic oxygen lance is numerically simulated by software Fluent and the position of the protection gas, the effects of jet-flow angle and pressure intensity on the jet-flow behavior of the cluster oxygen lance are analyzed and production practice is conducted at the 110 t EAF in Tianjin Iron ＆ Steel Group. Results show that the EAF steelmaking in the corporation is improved and the average refi- ning cycle reduced by 10 to 15 minutes and all indicators of consumption lowered since adoption of the cluster oxygen lance.
