A computer model has been developed for describing the flowfields of molten steel (SUS 304) in the twin-roll strip casting process with solidification pattern. The governing equations were transformed to a curvilinear coordinate system and an outline of the computational approach was also given. It was found that the flowfields with recirculating flow are located in the vicinity of the middle of the rotating bank of molten steel. The small cavity zone with fixed operation parameters appears with the nozzle depth increased.
