A mathematical model was used to investigate the liquid steel flow characteristics in centrifugal flow tundish for continuous casting.Effects of dam position and rotating magnetic intensity on flow structure were described

and the availability of calculation results was verified by the experiment.The results indicate that a near-distance from the dam to the exit of rotation chamber can promote the formation of the circumfluence in the distribution chamber

which is beneficial for removing inclusion

while a larger distance can result in obvious asymmetry flow structure in distribution chamber

and the asymmetry structure is more and more evident with the increase of dam distance

which is unfavorable for the mixture of liquid steel

leading to the formation of blind zone.Effects of magnetic flux intensity on liquid steel flow pattern can be neglected with the magnetic intensity more than a critical value.
