中间包内流体停留时间分布测定方法的探讨

Discussion on Measuring RTD Methods of Tundish Fluid Flow

在连铸中间包的水模型实验中，对两种不同的停留时间分布的测定方法进行了比较分析。结果表明，只有将电导电极置于水口出流部位的测定方法才能客观地反映中间包内流体的流场分布情况。

By means of water model experiments of continuous casting tundish, two different methods of measuring residence time distribution are analysed. Results show that the measuring method with the conductivity electrode placed at the nozzle outlet can describe objectively the distribution of the tundish fluid flow.
