Abstract
Considering the centrifugal force in the experiment of hydraulic simulation, numerical simulation of mold filling for Titanium alloys has been investigated in this paper, as well as the mathematical mold of fluid filed for mold filling in vertical centrifugal casting was established. Based on the mathematical mold that mentioned above, the filling simulation at different rotational speed and different radius of sprue were finished. The simulation results show that the filling speed increase with increasing of rotational speed and radius of sprue. Compare with radius of sprue, the rotational speed influence the filling state more obviously. It also can be found from the simulation results that the bottom filling is more stable, and the filling speed in cavity depends on the filling speed at entrance of runner and the ration of cross-section area in runner and cavity. The simulation results show good agreement with the experimental results, confirming the accuracy of the model.
