Opis:
In the full mould process, the polystyrene pattern which fills the mould cavity is subjected to pouring of this mould with liquid metal to the effect of high temperature (1600 0C) and passes from the solid state into liquid and gas. During this process some solid and gaseous products of the thermal destruction of the pattern are created. The kinetics of this process depends on the temperature of evaporation and, though to a smaller extent, on the pattern density, which, combined with the mould parameters, parameters of a ceramic coating, i.e. its thickness, permeability, and resistance to the effect of high temperatures, parameters of a granular material filling the mould and parameters of a technological process, including the technique of pouring and design. The mould cavity is filled with a pattern made of foamed polystyrene which on pouring of mould with liquid metal undergoes total destruction.

Opis:
In the method of full mould the polystyrene model, which fills the mould cavity in the course of filling by the liquid metal is subjected to the influence of high temperature and passes from the solid, through the liquid, to the gaseous state. During this process solid and gaseous products of thermal decomposition of polystyrene patterns occur. The kinetics of this process is significantly influenced by the gasification temperature, density and mass of the polystyrene patterns. One of the basic parameters is the amount and rate of gas from the polystyrene model during its thermal decomposition. Specific properties of ceramic layer used for lost foam castings are required. To ensure optimal process flow of metal in the form proper permeability of the ceramic layer is needed. To ensure optimal conditions for technological casting method EPS patterns are tested and determined are the technological parameters and physical-chemical process in: material properties of the pattern, properties of the ceramic layer applied to the pattern, pattern gasification kinetics, pouring process. In the course of the research the characteristics of polystyrene and ceramic layer were determined.
