In this paper,with the FEM analysis software-ANSYS, steady-layer melt fluid in the aluminum casting mouth was simulated and analysed.Three dimensions model was established and the coupled solution of three dimensions thermal-fluid coupled-field was solved using finite element analysis.The simulated diagram of the fluid velocity,pressure and temperature distribution was achieved.The law of velocity and temperature distribution in the outlet of casting mouth was studied,and its effect on continous casting and rolling was analysed.
