Abstract

We present the results of simultaneous measurements of the flow field in a slab casting mould by the Contactless Inductive Flow Tomography (CIFT) and of the gas/liquid distribution in one cross section of the submerged entry nozzle (SEN) by the Mutual Inductance Tomography (MIT) for a physical model consisting of a mould with the cross section of 140 x 35 mm2. Additionally, we present a new measuring system for CIFT using pickup coils and the first measurement of the flow field in a mould with the cross section of 400 x 100 mm2.
