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.
