Mathematical modeling of multiphysics processes of Joule heating has been conducted, using a finite-element model of a stationary current-carrying mould (CCC). To manufacture bimetallic products using a stationary current-carrying mould with a circular cross-section during melting of a discrete additive at its batch feeding, the study presents the results of calculated assessment of the dependence of such metal pool shape parameters as the mirror diameter and the liquid fraction depth on the slag pool depth and CCC design parameters, namely the mould diameter, the thickness of copper bushings in the mould currentcarrying and forming sections, the water-cooled pallet thickness, and the variations in the graphite lining height, because of wear. The findings will contribute to improvement of the mould design, optimization of the metal pool shape, and the technology of discrete additive melting at batch feeding in stationary CCC.
