Thermal simulation of process formation composite layer on model casting

Purpose: In article the results of thermal simulation of formation composite layer on model cast steel casting process have been presented. The aim of researches was determination of technological parameters of formation composite layer process for which is possible to obtain good quality reinforcement layer with desirable thickness. Design/methodology/approach: For assumed changes of chose technological parameters, distribution of temperature in model casting as well as course of temperature changes in characteristic point of composite insert have been determined. Simulations have been carried out for two different materials of compositing element (insert) and three different pouring temperatures with software NovaFlow&Solid 2.9 r81. Findings: Obtaining good quality and with desirable thickness composite layer depends on process and level of heating during casting process. Research limitations/implications: Researches made possible to determination which technological parameters directly influent on this process and how criterions should be meet by casting technology of this kind of casting. Originality/value: Obtained results and their experimental verification will make possibility to form a basis for work out guidelines and principles for design technology of casting with composite layer on choose surfaces productions.
