Purpose: In this article the thermal simulation of formation composite layer on steel model casting and real casts were presented and described. There is also shown a computer program to determine the thickness of composite layers with the use of stochastic process. The main aim of researches was to prove the correctness of the method based on the calculus of probability thanks to the results of real casts. Design/methodology/approach: Both the distribution of temperature in model casting and the course of temperature changes in the 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 and Preforma 1.1. Findings: The desirable thickness of composite layer depends on the parameter ts of process and the level of pouring temperature during the casting process. Research limitations/implications: Researches made possible to determine the thickness of composite layers and, thanks to it, to project the desirable composites. Practical implications: Thanks to obtained results there is a possibility to project the thickness of composite layers in concrete places with the help of only a few data.
