A mathematic model of mold filling and solidification in horizontal centrifugal casting is built up. Based on this model, the temperature field and the flow field in horizontal centrifugal casting are numerically simulated. The hydraulic experimental results are compared with numerical simulations, indicating that the mathematic model is accurate. Experimental results show that liquid fills the mold in the manner of a spiral trajectory in the centrifugal casting process. The filling pattern tends to be more uniform with the increase of rotational speed. The present study has a guiding significance to the production of horizontal centrifugal casting roll.
