Abstract: A very close to realistic production soft-contact EMCC (electromagnetic continuous casting) round billet mold was introduced, and the corresponding three dimensional mathematical model for electromagnetic fields was developed. The mathematical model was numerically solved using finite element method under well-posed conditions. After the validation of numerical results by experiments, the three dimensional distributions of magnetic flux density in the soft-contacting EMCC mold were systematically investigated. The errors between numerical and experimental values are less than 5 percent. The relations between magnetic flux density and all structural and operational parameters are obtained quantitatively, which will provide a theoretical quidance to the design and operation of soft-contacting EMCC round billet mold.
