Abstract

A computer model has been developed for describing the flowfield of molten metal in the twin roll strip casting process with turbulent flow. The formulation of the twin roll strip casting process was based on the turbulent Navier-Stokes equation in which allowance was made for the spatially distributed turbulent velocity field of molten metal. The equations were simplified to those for axisymmetrical flowfields and an outline of the computational approach was also given. The calculation of turbulent properties using the standard two equation k-ε turbulence model has been applied, and predicted results are presented. Also, it was found that turbulent flowfields with a recirculating zone are located in the vicinity of the middle of the rotating bank of molten metal. The size of the recirculating zone with fixed geometry configuration decreases with increasing inlet flow rate.
