In this article the results of thermal simulation of formation composite layer on steel model casting were presented. The aim of researches was to determine the technological parameters of formation composite layer process for which it is possible to get good quality reinforcement layer with desirable thickness. Methodology. Both the distribution of temperature in model casting and the course of temperature changes in characteristic points of composite premould were determined for assumed changes of chosen technological parameters. The numerical calculations were done with the use of software NovaFlow&Solid 2.9 r81. Finding. Obtaining both the good quality and desirable thickness of composite layer depends on the parameters of process and the level of pouring temperature during the casting process. Research implications. Researches made possible to determine technological parameters directly influencing this process and criterions which should be kept by casting technology of this kind of casting. Practical implication and value. Thanks to obtained results there is a possibility to work out guidelines and rules of projecting the construction and the selection of technological parameters of casting with surface composite layer.
