Abstract

It is important to predict roll forces and microstructural evolution in the hot rolling process in order to improve product quality and process optimization. Based on parameters such as chemical composition, temperature, and strip dimensions, many authors have developed equations to predict it. In this work, it was compared industrial roll force to those predicted by Misaka and Siciliano’s models. After that, a linear regression was performed to improve correlation between industrial data and calculated forces. It was possible to obtain values of f < 10% above 80% and RMSE between 100 and 190 tons. The observed results show that with a simple linear regression it is possible to improve the adjustment of the equations for the data of a given industrial plant.
