Singularity consideration in the integral equations for contactless inductive flow tomography
COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 2018Purpose The contactless inductive flow tomography is a procedure that enables the reconstruction of the global three-dimensional flow structure of an electrically conducting fluid by measuring the flow-induced magnetic flux density outside the melt and by subsequently solving the associated linear inverse problem.

Some methodological improvements of the contactless inductive flow tomography
International Journal of Applied Electromagnetics and Mechanics, 2009The goal of contactless inductive flow tomography (CIFT) is the velocity reconstruction in electrically conducting melts which are used in many metallurgical and crystal growth applications. In this paper, we discuss some recent methodological improvements of this method, in particular the automatic search for an optimum regularisation parameter and ...

The flow structure in the mold of a continuous caster has a great influence on the quality of the produced steel. Conventional flow measurement techniques are prevented by the high temperature of the liquid steel. For a physical model of the continuous casting process using a low‐melting point liquid metal, we present combined measurements of the flow ...

Flow Control in the Model of a Continuous Caster by Using Contactless Inductive Flow Tomography
Materials Processing Fundamentals 2019, 2019The global flow pattern of liquid metal in the slab mold of a continuous caster is difficult to control, as it cannot be measured in real-time by conventional methods. Contactless inductive flow tomography (CIFT) can easily provide real-time information about the flow structure (double or single roll) and the angle of the jet coming out of the ...

Contactless inductive flow tomography for a model of continuous steel casting
Measurement Science and Technology, 2010The contactless inductive flow tomography (CIFT) aims at reconstructing the velocity field in electrically conducting melts from externally measured induced magnetic fields. One of its possible applications is the velocity reconstruction in the continuous casting process.

AbstractIn continuous casting DC magnetic fields perpendicular to the wide faces of the mold are used to control the flow in the mold. Especially in this case, even a rough knowledge of the flow structure in the mold would be highly desirable. The contactless inductive flow tomography (CIFT) allows to reconstruct the dominating two-dimensional flow ...
