An importance of thermophysical properties on calculation accuracy of thermokinetics of solidification

Popis výsledku v původním jazyce

The thermophysical properties of steels have significant influence on the actual casting process, and on the accuracy of its numerical simulation and optimization. On a steel sample casting of cylindrical shape that was cast in a non-metallic or metalliccylindrical mould the analysis of influence and importance order of the main thermophysical properties of casting and moulding materials on calculation accuracy of temperature field in the system of casting-mould-environment has been performed. As a comparing datum of accuracy the total time of solidification (crystallisation) has been selected. For the cast material, the influence of heat conductivity , specific heat capacity c, density , and namely in the liquid or in the solid phase, in addition oflatent heat of phase transformation L also has been analysed. For metallic or non-metallic moulding material an influence of the same main parameters has been analysed and in addition their combination, temperature conductivity a and of h
