APPLICATION OF «HOT» DISSOLUTION OF POLYSTYRENE MODELS IN THE PRODUCTION OF CASTINGS IN SHELL-SHAPED FORMS FROM COMPLEX-MODIFIED CERAMICS
Keywords:
heat-resisiting alloy, ceramic mold, polystyrene, «hot» dissolution, thermo kinetic parameters, porosityAbstract
The results of investigations of ways of intensifying the process of dissolution of casting models from different types of expanded polystyrene by the method of «hot» dissolution are given. The influence of the thermo-temporal conditions of the process for several kinds of solvents is established. Advantages of the proposed method are shown in comparison with investment casting for both the
improvement of surface quality and the reduction of time costs in obtaining complex-shaped castings
