The centrifugal casting process of 6082 Al alloy was simulated by ProCAST software. The effects of rotation speed and heat transfer coefficient on the filling and solidification behaviour were analysed. The porosity of the cast pipe increases with the increase of the rotation speed and decreases with the increase of heat transfer coefficient. The CAFE model was used to simulate the grain structure of centrifugal cast Al alloy under different process conditions. When the rotation speed and heat transfer coefficient increase, the length of columnar crystal region will increase and the grain will be refined.
