The present study examines the performance of a resistance heating furnace using two different heating elements, Silicon Carbide (SiC) heating rods and Molybdenum Di-Silicide (MoSi₂) heating elements, where SiC rods are used first, starting from the beginning (ambience) temperature of 35ᴼC up to 1300ᴼC, followed by MoSi₂ heating elements to raise the chamber temperature from 1300ᴼC to the set temperature of 1600ᴼC. To achieve effective insulation results, newage high alumina (Al₂O₃), very low thermal conductivity (K), and high density materials such as zirconium tiles, mullite tiles, and zirconium modules, all with such necessary insulation properties sandwiched, are used. Air, a bad conductor of heat transfer, is also used in a gap of 20 mm between two different tiles to lessen heat transfer from the working chamber towards the outer ambience by conduction and radiation to achieve desirable results-maximum thermal efficiency with the least heat loss from the outer surface and to achieve skin temperature equal to the ambient temperature. Also, in this experiment, hot-faced red bricks are used under the hearth in a new design. The system under study consists of a programmable Proportional Integral Derivative (PID), a thyristor power pack, recrystallized alumina tubes, and sensing elements: a thermocouple and Pt-Pt/13%. Rh, semiconductor-based circuit that controls power and current. This makes the system to meet the requirement (step down) and thereby controls voltage automatically with a transformer (depending on the size of the working area, 53 A (I), 220 V for single phase, reduced to 60 V by a step down transformer) auto-current-limiting facilities.
