Thermal treatment in electrical resistive ovens — Modeling and simulation of the air temperature and the parts to be treated

This paper deals with the heat transfer within an electrical oven. It is presented the mathematical model, first without anything inside (the preheating period), and after that with parts to be heated, in order of thermal treatment. The simulation subsystem for the air temperature and the simulation scheme of the parts inserted are developed in order to present the dynamic behaviour of the simulation before and after inserting the parts into the oven. The results of the simulation are done for two different powers installed, High Power and Low Power.
