摘　　要：针对９０ｔ多功能ＲＨ精炼装置内钢液的流动特性进行了水模拟研究．采用更为精确可靠的方法对环流量进行了测定，给出了该精炼装置的环流量计算公式：Ｑｌ＝０．０２７１Ｑ０．２６ｇＤ０．７２ｕＤ０．８４ｄ（ｔ／ｍｉｎ）．用示踪法对ＲＨ钢包内的流动状况进行了显示，验证了Ｔｓｕｊｉｎｏ的数学模拟结果，否定了ＲＨ上升管与下降管间“短路”现象的存在．By using the water modelling method, the flow characteristics in RH process have been studied for a multifunction unit of 90 t capacity. The circulation rate has been measured by a more precise and more reliable method and the circulation rate of molten steel in this unit can be estimated with the following equation: Ql=0.0271Q0.26gD0.72uD0.84d (t/min). The flow field in RH ladle has been visualized by tracer method and the results agree well with 3D mathematic model of Tsujino. No bypass flow exists between downleg and upleg.
