Abstract
The flow structure of liquid steel in the mold of a continuous caster has huge impact on the quality of the produced steel. In order to influence the flow during the casting process electromagnetic brakes (EMBr) are used. Even a rough knowledge of the flow field would be highly desirable. The contactless inductive flow tomography is a technique for reconstructing the velocity field in electrically conducting melts from externally measured induced magnetic fields. For a physical model of a mold with a cross section of 140 mm × 35 mm we present preliminary measurements of the flow field in the mold in the presence of a magnetic brake. In addition, we show first reconstructions of the flow field in a mold with the cross section of 400 mm × 100 mm, demonstrating the upward scalability of CIFT.
