Abstract:
A mathematical model is developed for calculating the temperature field established in liquid alloy after filling a lost foam casting mold when filler metal particles are placed in a expanded foam polystyrene model. The effect of a stepwise drop in temperature of the cast alloy caused by thermal destruction of foam polystyrene and heat exchange with filler particles is observed. The dependence of this effect on filler volume fraction in the area of its location and ratio of thermophysical properties of the basic alloy and filler material is established.
