The paper summarizes the develo0ment of a two-dimensional (axisymmetric) and a three-dimensional mathematical model for electromagnetic casters of the two types used in the aluminum industry, which may soon be applied to other metals. A physical model where liquid metal is simulated by Wood's alloy is described and measurements of magnetic field, electric field, meniscus deformation and melt velocity reported. Some of the measurements are compared to the predictions of the 2D model and found to yield approximate agreement.
