Macrosegregation Prediction by Evaluating Liquid Level Fluctuation in Round Billet Continuous Casting with Electromagnetic Nozzle Swirling Flow.

Under the joint action of electromagnetic swirling flow in the nozzle (EMSFN) and mold electromagnetic stirring, Liquid level fluctuation in the mold is investigated to find the optimal combination parameters for the occurrence time of the minimum macrosegregation degree in continuous casting of round billet. When the current intensity of EMSFN device is 450 A, the optimal carbon range 0.045 pct appears, after the fluctuation reaches the minimum with the current intensity at 400 A. [ABSTRACT FROM AUTHOR]
