SUMMARY:Development and implementation of a full-scale simulator based on liquid metal for the analysis of flow dynamics in continuous casting moulds
DESCRIPTION:Steelmaking processes occur at high temperatures (in excess of 1500° C) which makes experiments and measurements on liquid steel very difficult. A good alternative to model the behaviour of liquid steel is to use low-melting point alloys with similar density and viscosity (for example: Bi-Sn, Tmelting: 150°C).

SWERIM is home to one of the most advanced facilities for physical modelling with liquid metal for casting in the world. This facility is used as benchmark to test flow control devices such as nozzles, stoppers and sliding gates during continuous casting operations.

The present manuscript describes recent work to increase the size of the simulator to full-scale for wide and thick slabs as well as reaching casting speeds and Argon flow rates equal to those applied in the Industry. The Simulator has been also equipped with a series of measurement techniques to monitor pressure, velocity, temperature, level fluctuations and vibration in order to fully characterize the metal flow in CC moulds.

Finally, the present paper enumerates the main findings, challenges and limitations derived from extensive tests in the simulator with real ceramic nozzles/stoppers and their counterparts in stainless steel.
