Modelling of the strand and mold temperature in the continuous steel caster

The finite element 3D model has been developed to study the heat transfer and fluid flow in the mold region for the continuous steel casting. The strand and mold temperature is controlled by the heat transfer through steel – mold interface. The thermal resistance of interface layer has been modelled taking into consideration the convection heat transfer coefficient between the liquid steel and mold surface as an upper limit and the radiation heat transfer as a lower limit. An empirical equation has been derived to model heat conduction through the steel – mold interface. The computation has been performed to study the model response to thermal resistance of the mold –steel interface and the casting speed.
