Abstract

It’s necessary to ensure the stability of a horizontal continuous casting five-strand tundish for casting aluminum.To obtain uniform temperature distribution and fluid flow

the flow-control device of a tundish for a five-strand horizontal continuous caster was designed and optimized using three-dimensional mathematical modeling and water simulation experiments.The results reveal that the velocity of aluminum melt exhibits uniform at outlet

and it is near to the casting speed as a whole by utilizing the flow control device.The maximum temperature difference in the whole original tundish is 15 K

while it is 9 Kin the optimized tundish with flow control device

decreased by 40%.The maximum temperature difference of each outlet in the original tundish is 7 K

while it is 2 Kin optimized tundish

decreased by71.4%.The flow control device of a five-strand tundish designed is beneficial to improving the quality of ingots and stabilizing manufacturing process.
