摘要: 用流体商业软件Fluent对50 t转炉氧枪喷头的冷却水流动进行数值模拟,从冷却水流动的速度矢量图分析其流动特征。通过模拟分析,提出一种兼顾控制冷却水流动、提高冷却效率和喷头端面强度的带有水冷隔板的新结构氧枪喷头。模拟结果表明,由于新结构氧枪喷头内形成独立的进回水通道,可减少水流在水冷腔中对冲造成的能量损失和喷头中心水流死区的产生,有良好的冷却效果,增强了端部中心机械强度,抑制喷头变形。

Abstract: The numerical simulation on flow of cooling water in oxygen lance nozzle for a 50 t converter has been carried out by a commercial software Fluent to analyze its flow characteristics through velocity vector diagram of cooling water flow. By simulation and analysis, a new pattern oxygen lance nozzle with cooling water clapboard to simultaneously control cooling water flow, increase cooling efficiency and strength of nozzle section is proposed. Simulation results show that as an independent inlet-back channel in new pattern oxygen lance nozzle, the energy loss due to opposed jet flow impact in cooling water chamber and the flow dead zone in center of nozzle decrease, this structure has better cooling effects to enhance nozzle head central mechanical strength and restrain distortion of lance nozzle head.
