Flow measurements in a continuous casting model using a low temperature liquid metal

This paper describes experimental investigations of flow structures and related transport processes in the continuous casting mould under the influence of an external DC magnetic field at laboratory scale. Experimental results will be presented here which have been obtained using a physical model (mini-LIMMCAST) operating with the low melting point alloy GaInSn. The Ultrasound-Doppler-Velocimetry (UDV) was applied for measurements of the flow pattern in the mould. An array of ten transducers was attached to the narrow mould side, measuring the horizontal velocities in the the region around the liquid metal jet. Further, with two sensors on the mould top, vertical velocities were recorded successively in the whole mould width.
