Melt-Particle Mixing in Gas-Stirred Ladles with Throughflow by Speckle Photography

提出了一种散斑照相法和湍流两方程模型来评价具有通流的气体搅拌钢包内熔体-颗粒混合的性能。层流和湍流研究将在简化的水模型上进行。流动模式将由激光光片流动可视化技术确定，并将通过自动图像处理进行分析。研究结果可用于通流气体搅拌槽内熔体-颗粒混合的性能优化。这项研究的应用包括钢包冶金，如铁水和钢铁的脱硫，以及有色金属工业，如铜和铝加工。

A speckle photographic method and a turbulence two-equation model are proposed for the performance evaluation of melt- particle mixing in gas-stirred ladles with throughflow. Laminar and turbulent flow studies will be performed on a simplified water mode. The flow pattern will be determined by a laser light-sheet flow visualization technique and will be analyzed with automated image processing. The results can be used for the performance optimization of melt-particle mixing in gas-stirred tanks with throughflow. Applications of the study include ladle metallurgy, such as desulfurization of molten iron and steel, and nonferrous industries, such as copper and aluminum processing.
