The structure and properties of cast iron castings depends not only on the chemical composition of molten cast iron and the technology of its smelting, but also on many other conditions such as cooling and crystallization of castings, especially on further solidification of castings in casting molds. The article presents the established dependences of the influence of the cooling rate of castings on the mechanical properties of the obtained parts, the investigated microstructures of experimental samples from the selected molding materials and it is established that the thermal conductivity of materials affects the structure of graphite in cast iron castings. Computer models of dependencies and regression equations of the processes are proposed.
