This paper aims at studying the iron casting solidification and the optimisation of the design parameters by means of numerical simulations. In particular, the aim of computer modeling has been the prediction of solidification pattern, indicating where shrinkage cavities and associated defect could arise, and simulate solidification with the casting system in different positions, in order to select the optimal position. To this purpose, the software MAGMASOFT was used to simulate the solidification of simple iron castings with a ring shape, obtained by means of shell moulding processes with different gating systems. For each different gating system, that involves a different filling, an analysis of the cast alloy solidification behaviour was performed by means of several solidification criteria such as the gradient, cooling rate and feeding ones.

Abstract
This paper aims at studying the iron casting solidification and the optimisation of the design parameters by means of numerical simulations. In particular, the aim of computer modeling has been the prediction of solidification pattern, indicating where shrinkage cavities and associated defect could arise, and simulate solidification with the casting system in different positions, in order to select the optimal position. To this purpose, the software MAGMASOFT was used to simulate the solidification of simple iron castings with a ring shape, obtained by means of shell moulding processes with different gating systems. For each different gating system, that involves a different filling, an analysis of the cast alloy solidification behaviour was performed by means of several solidification criteria such as the gradient, cooling rate and feeding ones.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
