Abstract
In continuous casting the flow of the liquid steel in the mold has great impact on the quality of the produced steel. During casting even a rough knowledge of the flow field would be highly desirable in order to control process parameters or electromagnetic actuators. The high temperature of the liquid steel recommends a contactless measurement technique.
The contactless inductive flow tomography (CIFT) is able to reconstruct the dominating two-dimensional flow structure in a slab casting mold by measuring the perturbation of an applied magnetic field outside the mold and solving a linear inverse problem. In this paper we will give an overview of the application of CIFT to two models of continuous casting available at the Helmholtz-Zentrum Dresden – Rossendorf. For a physical model of a mold with a cross section of 140 mm × 35 mm we present the new measurement system using induction coils and show 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. We will conclude with recent developments towards an implementation in industry.
