Fluid Flow and Mixing in a Six Strand Bi

The continuous casting of steel has become increasingly relevant, particularly regarding the role of the tundish as a key component in improving steel cleanliness. The objective of this study is to investigate the effects of a new flow control device, known as the Advanced Pouring Box (APB), on the mixing performance within a multi-strand tundish. The methodology involves both experimental and numerical studies, focusing on the residence time, plug volume, and the minimization of dead volumes typically associated with traditional flow control devices. Results indicate that the application of APB significantly enhances the mean residence time and plug volume while reducing stagnant areas, thereby promoting better mixing efficiency in the tundish. These advancements hold considerable potential for reducing inclusions and improving steel quality during casting processes. The findings contribute to the understanding of optimal flow conditions in tundish design and operation, emphasizing the importance of innovative flow control strategies in steel manufacturing. The study highlights the APB's role in mitigating startup and ladle change issues, as well as its influence on reducing turbulent zones that can adversely affect steel quality. Such insights are critical for ongoing efforts to enhance steel production processes.
