摘要
本文介绍利用紊流下形阻系数近于常数的条件，对６０ｔ吹氩钢包内的主流股流速进行实际测量的原理、方法和结果。结果表明，包内钢液的主流股流速数量级为１０￣（－１）～１０°ｍ／ｓ，常在０．１～０．４ｍ／ｓ间波动，并与（ｇＱ＿０）￣（１／３）成线性关系。在实测基础，利用Ｎａｖｉｅｒ－Ｓｔｏｋｅｓ方程和ｋ－ε紊流模型通过ＳＩＭＰＬＥＲ方法对钢液流动进行了计算，计算结果与实测数据基本相符。
The principle and method to measure directly the main flow velocity of liquid steel ina 60 tons argon-stirred ladle by a probe(an immersed body)were introduced in the paper. The mainflow velocity of liquid steel in argon-stirred ladles was the order of 10￣(-1)-10￣0m/s, normally fluctua-tingin the range of 0.1～0.4m/s, and proportional to(gQ_0)￣(1/3). On the basis of experiments,theliquid steel flow velocities were predicted by using mathematical modelling,and the predictions were in good agreement with the measurements.
