Low Pressure Casting

It has been proved that the mold filling under low pressure casting can be described by the second order nonlinear differential equations characterized by damping oscillations. To obtain higher accuracy of the velocity field, the mold filling process with damping oscillations should be considered. A computational model taking the liquid level droping in the crucible into account based on two phase flow for filling process of damping oscillations is presented in this paper. Hydraulic simulation with the particle image velocimetry was adopted to verify the numerical simulation result. It is proved that the nemuerical simulation results used the presented model perfecly match with the particle image velocimetry results. Liquid level droping in crucible is the main reason for damping oscillations in mold filling. Velocity oscilations can be eliminated when the melt flow across a sudden expansion section. The detailed flow field based on the presented model can provide guidance to optimize the process parameters.

Effects Of Rotation

Mold filling process in horizontal centrifugal casting was analyzed in this paper. The effects of rotation speed on flow pattern were studied. Results show that the flow pattern changes greatly with increasing rotation speed and the first thread interval shows significant differences within each group. It is found that inappropriate rotation speed results in liquid drop during filling process, leading to casting defects.
