Abstract

The “giga-casting”, a technology for casting one-large aluminum product, has been attracted much attention in the automotive industry. For stable production with giga-casting, the quality control of molten aluminum is important. Understanding the behavior of inclusions in the entire molten aluminum is necessary for efficient and reliable control of cleanliness of molten aluminum. Computational fluid dynamics is helpful to understand the behavior of inclusions in the entire molten aluminum and to extend the scale from laboratory scale to the actual scale. In this study, the behavior of inclusion in molten aluminum is simulated with the Moving Particle Hydrodynamics (MPH) method. As a result of conducting the simulation with different values of the effective radius, it was found that the alumina particles tend to settle more easily when the effective radius is larger. In addition, by simulating the experiment with the MPH method, the sedimentation rate of the alumina particle was on average close to the experimental results.
