摘要
The first micro segregation under conditions of twin roll strip casting was simulated. The relationship between the temperature and solid fraction in the mushy zone was given. The temperatures such as ZDT, LIT were got from this simulation. Then using the turbulent model, the flow field and thermal field in the pool of twin roll strip caster was simulated. The speed and temperature at different casting speed was given, and the results were also explained. By these two simulations, the appropriate casting speed can be found. These simulations can provide effective data for controlling the twin roll strip casting process.
