The Electromagnetic Induced Segregation (EIS) of cast parts is an innovative technology for diecasting aluminium alloys. Using numerical simulation, an inductor system has been developed to produce a primary silicon concentration gradient during casting. The report shows the advantages of numerical simulation in research and development. A suitable inductor has been designed and its electromagnetic field optimized for the EIS. The numerical model is 2D for geometries with cylindrical symmetry and 3D for non-symmetric products. The inductor system is implemented in a pilot installation. With the metallurgical results, the interaction between the electromagnetic field and the location of primary silicon is investigated. Figs 7, Refs 1.
