Interaction of a Liquid Metal with Dispersed Steel Inclusions during Lost-Foam Casting

Resumo

A mathematical model is developed to describe the interaction of a liquid metal with the metallic inclusions introduced into cellular polystyrene in a casting model. This model takes into account the filling kinetics of a mold, the influence of the thermal destruction of cellular polystyrene, and the heat exchange between the base alloy and the filler material. The results of experiments on lost-foam casting of samples support the predictions of mathematical simulation.
