摘要
运用试验和数值模拟相结合的方法研究了273氧枪喷头射流的空气动力学特性,结果表明,试验喷头的合理吹氧压力为0.9MPa左右,合理的操作枪位为1600~2000mm;喷头的射流中心线与喷孔中心线偏移距离均小于等于30mm,可以满足使用要求;枪位对射流截面面积的影响程度大于压力的影响,枪位是控制熔池反应速度的有效手段。
The aerodynamic characteristics of 273 oxygen lance nozzle are studied by means of experiment and numerical simulation.The results show that the reasonable oxygen blowing pressure of the nozzle is about 0.9MPa,and the reasonable operating gun position is 1600~2000mm.The offset distance between the jet center and the nozzle center is less than or equal to 30mm,which can meet the use requirements.Gun position has greater influence on jet cross-sectional area than oxygen pressure,and gun position is an effective means to control the reaction rate.
