Abstract:
Tilting-type automatic pouring machines are used for gravity casting in manufacturing processes, and their pouring speed is set by workers through trial and error. Therefore, it is difficult to achieve pouring that results in high-quality casting and high process yield. On the other hand, in recent years, this control input has been derived by computer using a CFD simulator. However, the computation of a single condition currently requires a few hours, and the entire optimization requires hundreds of such computations. Thus, a considerable amount of time is required in order to perform an optimization using a CFD simulator. The purpose of this study was to design a calculation method for a pouring machine that would reduce the calculation time. The effectiveness of the proposed system is shown through CFD simulation.
