A three-dimensional mathematical model of electromagnetic casting and testing against a physical model: Part II. Results from a physical model and testing of the mathematical model

A physical model of an electromagnetic caster was constructed. The model was intended to provide measured data for comparison with the predictions of the three-dimensional (3-D) mathematical model described in part I. The physical model consisted of a molten Wood's metal pool (176×176 mm seen from above) on the top of an aluminum-bronze block. Probes were used to measure electric and magnetic fields, the deformation of the liquid surface, and the electromagnetically driven flow, at many positions within the melt, as a function of model geometry. Agreement between the measurements and the predictions of the mathematical model was generally good. The melt flow was 3-D and strongly influenced by the position of the electromagnetic screen interposed between the inductor and the metal pool.
