The major problem in rolling process is the defects like fire cracks, severe sticking in a billet mill, and etc. This paper deals with the study on reducing or minimizing the defects of rolling process. The analysis has been carried out for different temperature i.e. 100°c, 150°c, 200°c, 250°c. As the temperature goes on increasing correspondingly the residual stresses decreases. Hot rolling process helps in reduced residual stresses at high temperature & helps in formation of smooth granular structure of product. Due to the symmetry of the rolling components, half the model is built & the analysis is carried out with 4 roller sizes varying from 8mm to 20mm with 4mm increment & the results were tabulated by using ANSYS. This will helps in estimation of residual stresses.
