摘　　要：以300t RH为研究背景装置,建立了整个装置的三维数学模型。用双流体模型处理气液两相流,分析了吹氩喷嘴个数、垂直间距、排数和分布形式对钢液流场和循环流量的影响。结果表明:在工况吹氩量时,钢液流场变化趋势不大,循环流量随吹氩喷嘴个数增加先增加后降低;吹氩喷嘴垂直间距为150 mm更合适;吹氩喷嘴上下两排交错分布更合理。A three-dimensional mathematical model for simulation of molten steel flow in the whole 300 t RH unit has been established.Two-fluid model has been used.The influences of process parameters such as nozzles number,interval and row number which affecting steel flow behavior and circulation flow rate were simulated.Results show that,flow field has a little change and circulation flow rate is changed with number of nozzles,it is proper to control nozzles interval in 150 mm and in interleaving way.
