Modeling and simulation of the transient heating regime in an electrical oven

The model realized for the oven with electrical resistances was necessary to study the electrical and thermal processes that appear in such a complex industrial installation. A frequently problem, which appears during the use of these ovens, is the rapid aging who leads to the break down of the heating resistors. The use of this model has permitted us to emphasize many aspects that happen inside the electrical oven during the transient regime, until this one riches the stabilized work regime. The study of these phenomena has permitted to the designer to take some additional measures to prevent the undesired effects which can appear, regarding the automatic control of the temperature.
