Laboratory Investigation of Tomography-Controlled Continuous Steel Casting [PDF]
Sensors, 2022 More than 96% of steel in the world is produced via the method of continuous casting. The flow condition in the mould, where the initial solidification occurs, has a significant impact on the quality of steel products. It is important to have timely, and

A gradiometric version of contactless inductive flow tomography: theory and first applications. [PDF]
Philos Trans A Math Phys Eng Sci, 2016 The contactless inductive flow tomography (CIFT) is a measurement technique that allows reconstructing the flow of electrically conducting fluids by measuring the flow-induced perturbations of one or various applied magnetic fields and solving the underlying inverse problem. One of the most promising application fields of CIFT is the continuous casting

Challenges in contactless inductive flow tomography for Rayleigh--Bénard convection cells
Magnetohydrodynamics, 2022 Contactless 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 ...

Visualization of the global flow structure in a modified Rayleigh-Bénard setup using contactless inductive flow tomography [PDF]
Flow Measurement and Instrumentation, 2018 Rayleigh-Benard convection is not only a classical problem in fluid dynamics but plays also an important role in many metallurgical and crystal growth applications. The measurement of the flow field and of the dynamics of the emerging large-scale circulation in liquid metals is a challenging task due to the opaqueness and the high temperature of the ...

Flow monitoring for continuous steel casting using Contactless Inductive Flow Tomography (CIFT)
IFAC-PapersOnLine, 2020 Abstract The control of the liquid steel flow in the mould of a continuous caster based on real time flow measurements is a challenging task due to the lack of appropriate measurement techniques. The opaqueness, the high temperature of 1500°C and the chemical aggressiveness of the melt require non-optical contactless methods.

Contactless Inductive Flow Tomography: Brief History and Recent Developments in Its Application to Continuous Casting [PDF]
Journal of Sensors, 2014 The contactless inductive flow tomography (CIFT) aims at reconstructing the velocity field of electrically conducting fluids, with special focus on applications in metallurgy and crystal growth technologies. The method relies on the induction of secondary magnetic fields if the moving fluid is exposed to a primary magnetic field.
