Modeling and simulation of the heating elements into an electrical oven

In this paper we present the mathematical model of the thermal transfer within an electrical oven, first without anything inside and after that, with some parts to be heated on order of thermal treatment. We also present the simulation subsystem for the resistive elements and the simulation scheme of the entire oven. The results of the simulation are very eloquent; they are done for two different powers, High Power and Low Power. Following the results we found that it is a need to control the temperature of the part to be heated and a permanent monitory of the resistors´ temperature.
