Numerical simulation of the fluid flow, heat transfer and solidification of twin-roll strip casting

Using a microsegregation model, die relationship between solidus fraction and temperature in twin-roll strip casting process was got. A coupled three-dimensional flow, and heat transfer model was developed to simulate the twin-roll strip casting process by finite element method. The two equations k - epsilon model was used to incorporate the turbulence in fluid flow. The effect of the casting speed, pouring temperature of melt, and roll gap on die flow and temperature field was predicted die simulation results was compared with the experimental results and they are in good agreement.
