Abstract: Temp Core based technology was used in the production of thermo mechanically treated bars for higher yield strength. The Process involves rapid cooling of hot bars by passing the bars through a series of water jets after they are rolled through the finishing stand. One of the important quality parameter for the TMT bars is Yield strength. This Yield strength mainly depends upon various factors. The objective of this research is to select the optimal combination of the factors which will ensure the required yield strength and also to find out the contribution of each factor in the improvement of yield strength. In this research work, experimental readings were taken from the plant and it was analyzed by Taguchi Method to find out the optimum combination factors using MINITAB software. The Orthogonal Array (OA), Signal-to-Noise ratio (S/N ratio) and Analysis of Variance (ANOVA) were employed to optimize the process parameters. With the help of graphs optimum parameter values were obtained and the confirmation experiments were carried out.
