Flow Control in the Model of a Continuous Caster by Using Contactless Inductive Flow Tomography
Minerals, Metals and Materials Series, 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 ...

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.

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.

Enhancing robustness and applicability of contactless inductive flow tomography
2015 IEEE SENSORS, 2015Measuring the flow velocity in hot, chemically aggressive and opaque melts is a challenging task even for today's measurement techniques. The contactless inductive flow tomography (CIFT) could provide a solution by applying magnetic fields to an electrically conducting melt and measuring the small flow-induced magnetic perturbances outside of the ...

Increasing electromagnetic compatibility of Contactless Inductive Flow Tomography
2015 IEEE International Symposium on Electromagnetic Compatibility (EMC), 2015In many metallurgical and silicon crystal growth applications the knowledge about the flow field of the respective liquid metals is vital for proper process management. The high temperatures and the opaqueness of those melts set severe restrictions on the applicable flow measurement methods.

Challenges in contactless inductive flow tomography for Rayleigh--Bénard convection cells
Magnetohydrodynamics, 2022Contactless inductive flow tomography (CIFT) can reconstruct the complex 3-dimensional flow structure of the large-scale circulation in liquid metal filled Rayleigh-Bénard (RB) convection cells. The method relies on the precise measurement of weak magnetic fields induced by currents in the conducting liquid arising from the fluid motion in combination ...
