The study presents the findings of research on developing heating curves of heavy parts for the open die forging process. Hot ingots are heated in a chamber furnace. The heating process of 10, 30, 50 Mg ingots was analyzed. In addition, bearing in mind their high susceptibility to fracture, the ingots were sorted into 3 heating groups, for which the initial furnace temperature was specified. The calculations were performed with self developed software Wlewek utilizing the finite element method for the temperature, stress and strain field computations.
