Purpose: In this article, the results of thermal simulation of composite layer formation on the steel model casting are shown. The main aim of researches was to work out the technological parameters of composite layer formation process, for which it is possible to get good quality reinforcement layer with desirable thickness. Design/methodology/approach: 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 the chosen technological parameters. The numerical calculations were conducted with the use of software NovaFlow&Solid 2.9 r81. Findings: Both the good quality and the desirable thickness of the composite layer depend on the parameters of process and the pouring temperature during the casting process. Research limitations/implications: Researches made possible to determine technological parameters, which have an direct effect on this process, and the criterions, which should be taken by casting technology of this kind of casting. Practical implications: Thanks to obtained results, it is possible to work out the guidelines and rules for projecting the construction and the selection of technological parameters of casting with the surface composite layer. Originality/value: The obtained results and the analysis of them allow to determine the basic guidelines for designing technology and construction of casting with the composite layer.
