Sažetak
In many cases, due to the complicated conditions of heat exchange in the furnace chamber and the shape of the heated metal, heating conditions cannot be determined by means of traditional analytical calculations but must be found out experimentally. For that reason, a mathematical model of the heating process for a steel charge having an octagonal cross-section will be constructed on the basis of finite element analysis. Transient heat conduction analysis and thermal stress analysis will be performed in order to determine the allowable heating rate with regard to temperature distribution within the structure and the distribution of induced stresses and deformations. The latter are due to the heat transferred from the combustion gases and furnace lining by radiation as well as to the forced convection of combustion gases to the charge. The model will be verified with the help of experimental results obtained by temperature measurements of die main parameters of heating conditions.
