| 摘 要： | 在流场模拟计算的基础上,建立了RH真空精炼过程Al2O3夹杂物运动及去除模型.通过数学模拟计算,分析了RH精炼过程夹杂物运动规律,讨论了夹杂物尺寸、RH吹气量等对夹杂物去除的影响.研究结果表明:同一管径条件下,吹气量为1 400 L/min时,夹杂物的总去除率最高为66.1％且最快去除时间为202 s,是去除夹杂物的最优吹气量;同一吹气量条件下,下降管内径为700 mm时,夹杂物的去除率最高,可达71.31％,夹杂物去除时间最短,为217s.

| Abstract: | Based on the flow field simulation,a model for simulating the Al2 O3 inclusion movement and removal in RH refining process was established.Through the mathematical simulation calculation,the movement law of inclusion in RH was analyzed.Moreover,the effects of inclusion size and air-blowing rate on the inclusion removal were discussed.The results show that under the conditions of the same pipe diameter,the highest removal rate and shortest removal time is 66.1 ％ and 202 s respectively with the gas blowing rate 1400 L/min,which is also the optimal gas blowing rate.While under the conditions of the same air-blowing rate,the removal rate of inclusion in downcomer with 700 mm in diameter is the highest as 71.31％ and the shortest inclusion removal time is 217 s. |
