摘      要：The position of the solidification completed temperature of twin roll stainless strip casting process is very important to the quality of the casting strip. In order to control this position, the solidification completed temperature should be known at first. The present paper first simulated dendritic microsegregation under conditions of twin roll stainless strip casting, and got the relationship between the temperature and the solid fraction of the mush zone. The temperatures such as ZDT (equal to the solidification completed temperature) and LIT (liquid impenetrable temperature), et al., also can be found from this relationship. Then by using the turbulent model, the flow and thermal fields of the pool of the twin roll stainless strip casting and the speed and temperature fields of different casting speeds were given and also explained. The simulation results are coincident with the experimental results. Combined with the results of these simulations, the appropriated casting speed was found.
