| 摘 要： | 以300 t REDA和RH精炼装置为研究对象,借助计算流体力学软件模拟REDA与RH两种精炼工艺下钢液流动行为,从精炼过程流场形态、循环流量、氩气行程及熔池表面湍动能等方面进行分析,研究结果表明:RH对钢包底部熔池的搅拌作用强于REDA,REDA的单浸渍管结构有利于延长浸渍管寿命及提高钢液循环流量,REDA只需RH提升气体流量的30%便能达到相同的循环流量。

| Abstract: | The flow behavior of molten steel in REDA and RH ladle during refining process was simulated by using computational fluid dynamics software.Flow field in refining process,circulation flow rate,Ar blowing route,and turbulent energy distributed on bath surface were analyzed.The results show that,compared with REDA,RH provides a stronger stirring at the bottom of ladle bath;the single dip pipe structure of REDA contributes to prolonged service life of dip pipe and enhance circulation flow of molten steel.Consequently,REDA can save 70% of gas flow required for RH while generating the same circulation flow rate. |

| Keywords: | REDA RH flow field circulation flow rate |
