主　　题：twin-roll strip casting delivery system fluid flow level profile 

摘      要：In twin-roll strip casting process,transport phenomena of fluid in the molten pool directly affect the process stability and the quality of *** order to elucidate the fundamental transport phenomena in twin-roll casting,a commercial software called ProCAST was employed to simulate the transient fluid flow and level profile behaviors during the early stage of the process in this *** coupled set of governing differential equations for mass,momentum and energy balance were solved with the finite element method and the transient free surface problem was treated with a volume of fluids(VOF) *** effect of different delivery systems configuration on flow pattern,level profile in the pool was studied and analyzed in this paper. The new wedge metal delivery systems have been optimized for the twin-roll strip *** was shown that new type metal delivery systems had a preferable effect on the uniform distribution of fluid and level fluctuation in the *** simulation results also provide a valuable basis for the optimization of delivery system and process parameters during the initial pouring stage.
