To improve mechanical properties such as tensile strength, impact resistance, ductility, machinability, wear,
abrasion, corrosion, magnetic properties, electrical properties etc., different types of heat treatment processes are
carried out in the industries today. In heat treatment methods there are some Proportional-Integral-Derivative (PID)
controllers to control the temperature of different zones. Continuous monitoring of heating and cooling rate and also the
soaking time during the heat treatment process in the furnace is necessary. This paper is an automation proposal /
demonstration to M/s XYZ Ltd., for their heat treatment furnaces automation so that, real time monitoring and
controlling of the heat treatment plant becomes easy. In place of master-slave PID controllers, PLC and SCADA will be
the best solution to improve the quality of the heat treatment processes.
