摘要: 基于氧枪设计的经典理论,得出180 t转炉5孔氧枪喷头的入口直径55 mm,喉口直径37.2 mm,出口直径50.8 mm,收缩段长度44.6 mm,扩张段长度97.2 mm,喉口长度5 mm;采用CFD流体仿真软件模拟在相同环境温度下喷孔夹角13°~17°时氧枪射流流场,得出15°为180 t转炉氧枪最优喷孔夹角,其射流具有较强的穿透能力和较大的有效冲击面积。

Abstract: Based on classical theory for oxygen lance design it is obtained of oxygen lance nozzle with 5 holes for 180 t converter the diameter of inlet 55 mm, the diameter of throat 37. 2 mm, the diameter of outlet 50. 8 mm, the length of contracting section 44. 6 mm, the length of expanding section 97. 2 mm and the length of throat 5 mm ; with using CFD fluid imitation software to simulate the injecting fluid field of oxygen lance with 13°- 17° nozzle at same environmental temperature ,it is obtained for 180 t converter the optimum nozzle angle is 15°its injecting fluid has stronger immersion ability and larger effective impact area.
