Flow measurements in a liquid metal model of a bloom caster under the effect of rotary electromagnetic stirring

This paper presents an experimental study of electromagnetically stirred flow in the mold using a 1:3 scale acrylic glass model of the round bloom caster from voestalpine Stahl Donawitz GmbH. An electromagnetic stirrer was installed at the mold producing a rotating magnetic field (RMF). Flow measurements were performed by means of the ultrasound Doppler velocimetry (UDV) at room temperature in the eutectic alloy GaInSn. Up to 10 ultrasonic transducers were employed simultaneously in order to obtain a two-dimensional reconstruction of the flow structure. The experiment provides an extensive and valuable data base for validation of numerical methods.
