摘　　要：基于欧拉多相流模型建立REDA精炼过程钢液流动行为的数学模型,并借助计算流体力学软件PHOE-NICS对钢液流动过程进行仿真模拟,重点分析了底吹喷嘴位置、吹氩流量、浸渍管插入深度及浸渍管内径等工艺参数对REDA精炼过程流场及循环流量的影响。数值模拟结果表明:对于300tREDA精炼装置底吹喷嘴位置取1/2 R处为宜,浸渍管插入深度对循环流量影响不显著,扩大浸渍管内径可显著提高钢水循环流量,吹氩流量为1 200L/min时,钢液循环流量约可达到210t/min。Based on the Eulerian multi-phase approach,a mathematical model of molten steel flow behavior in REDA refining process has been established,the fluid dynamics software PHOENICS is applied to the simulation.This paper analyzed the effects of key factors,such as bottom blowing nozzle position,argon flow rate,submerged snorkel depth and snorkel inner diameter,on the flow field and circulation flow rate of molten steel in REDA refining process.The simulation results show that the reasonable blowing nozzle position is in 1/2 R of the 300 t REDA ladle;the submerged depth of snorkel is not a significant factor on circulation rate;the circulation flow rate will increase obviously with the increase of snorkel inner diameter.When the argon flow rate is 1 200 L/min,the circulation rate of molten steel can reach 210 t/min.
