The formation of an air gap at the mould-metal interface in vertical continuous easting has long been known to have a detrimental effect on the efficiency of the process, and has therefore! attracted many attempts at mathematical modelling and multi-dimensional numerical simulation. However, a recent approach has used asymptotic techniques to derive a quasi-analytical thermomechanical model that captures the essential coupling characteristics: that the formation of the air gap affects the heat transfer, whilst the heat transfer affects the stresses that lead to the formation and evolution of the air gap. In this contribution, we report on preliminary attempts to develop that model, which was for the casting of pure metals, to describe the casting of alloys.
