Simulation of metallurgical process has been recently subject of intense research, due to its reduction in the number of required experiments to control the process as well as saving time and energy. In gas carburizing of steel parts the amount of carbon at the surface of carburized parts is the most important specification of the process in term of achieving desired metallurgical properties. In the present research, the gaseous reactions in an endothermic gas generator has been simulated using MATLAB software where the equilibrium surface carbon percentage was obtained solving the equilibrium constant equations. The effect of variables such as air to fuel ratio in the endothermic gas generator, carburizing temperature, pressure inside the furnace, relative humidity and ambient temperature have been investigated. Besides, working conditions of the furnace been investigated to obtain desired carbon potential. Finally, results of the simulation have been compared with experimental results obtained from a gas carburizing furnace.
