The aim of the new near net shape casting process is to replace conventional methods of hot strip production with a more economical process. In the process being developed at the Institut für Allgemeine M etallurgie, Clausthal Technical University, liquid steel is cast on the moving belt cooled from below by water. The main problems at present are caused by friction against the stationary water-cooled copper side rails, which causes cracks and increased thickness in the side regions. Contactless electromagnetic side-dams have been developed to overcome these problems. In the current work, an inductor has been designed geometrically and electrically, which is able to confine without contact a strand with the desired thickness and width. A mathematical model was tested by applying it to cases for which amalytical solutions are known. Experiments confirmed the model computations, that is the melt was seen to be without contact with the inductor when the calculated values of voltage and frequency were attained.
