| Abstract: | A continuous casting tundish in a steel plant is constructed with nozzles for 3strand asymmetrical configuration, and the flow pattern and temperature of molten steel varysignificantly different among 3 strand nozzles. With the isothermal and non-isothermal watermodeling, several flow control designs were investigated. By using the design proposed in thepresent work, it was observed that the difference of molten steel average residence time between1st and 3rd strands was decreased by 58.1%, the temperature difference reduced by 81.6%, andthe dead zone volume of the tundish dropped from 23.2% to 8.3%. |
| Keywords: | continuous casting tundish flow control water modeling |
