Heat transfer characterization in the mould of a high speed continuous steel slab caster

The understanding of the heat transfer behaviour in the mould during continuous casting (CC) operation has been indispensable throughout the development of the high-speed casting process. While plant trials showed rate of increase of sticking breakouts during high speed castings, heat transfer models have been increasing applied for developing fundamental understanding of the mould behaviour and causes of such breakouts. The paper encompasses some of the analytical studies undertaken on the basis of mould heat transfer analysis and modelling of plant data to charaterise the thermal behaviour of the high speed mould and associated heat trasfer constraints for castingat higher speeds
