Abstract

Problem statement: The objective of this study was to study the Indirect Resistance Electrical Furnaces (IREF) based on analytical and experimental analyses. The analytical analysis focused on a constant set of equations representing the internal and external flow of heat energy in the furnace, which demonstrated, relatively with the surface area of walls, heat transferring inside the furnace chamber to get a creation mathematical model including the joining between the temperature required design components (furnace walls, thickness and electrical power supply). Approach: The experimental analysis has divided in to tow parts; first part based on process number of practice experiments with three prototypes have manufactured in certain engineering dimensions that changed in three different volumes of furnace, which are considered, i.e., chamber volume of furnace is the design dimensions component. Results: The second part of analytical analysis based on use the Simulink program (MATLAB 7.4) compared with experimental results of the manufactured furnaces samples, which showed the direct effect of the design dimensions components on the performance specifications of furnace that involve the required temperature response, temperature stability and the deviation in the setting value of temperature. Conclusion: Although information relating to the design and fabrication of an indirect resistance electrical furnaces of such prototypes as that fabricated through this research was not readily available in the literature.
