A mathematical model based on fluid mechanics considerations has been formulated to describe a single‐roll continuous strip caster. The heat transfer related phenomena are incorporated in the model through an empirical over‐all parameter. The model provides useful interrelationships between the final strip thickness and the operation and design parameters, e.g. the speed of rotation of the caster drum, the stand‐off distance, the nozzle passage gap and the liquid metal head in the reservoir. Simulating the process, using the model, it has been possible to predict the effect of these parameters on the final strip thickness. The model allows, though indirectly, the prediction of the conditions which would lead to choking of the liquid metal pool due to premature solidification. Comparing the results of this model with those obtained using the model based on heat balance considerations only, it is noted that the former predicts higher values of final strip thickness.
