“…For example, in none of the mathematical modelling studies referred to, [3][4][5][6][7][8][9][10] variation of incoming melt temperature through SEN, which is a characteristics of industrial continuous casting practice, have been taken into account. In few studies, 11,12) though the effect of casting temperature was analyzed by performing experiments 11) or, simulations, 12) at different and discrete values of superheat, rather than a continuous variation of melt temperature at SEN was considered. None the less, results have indicated that pouring temperature influences microstructure due to changes in segregation (micro/macro) profile and dendritic arm spacing, changing in turn properties of cast material.…”

Previous studies on the mathematical modelling of fluid flow-heat transfer phenomena in continuous casting, reported in this journal and elsewhere, are examined and, analyzed computationally. It is shown that mathematical model of continuous casting based on a constant, in lieu of a time varying inlet temperature, can produce different estimates of temperature field and solidified shell thickness in the mold. In contrast, thermal free convection phenomenon is found to be unimportant to the precise modelling of heat transfer in the mold. It is argued that a transient, rather than a steady state formulation, should be the preferred choice as the former ensures easy integration of additional process features as well as speedy convergence.
