An approximate method for computing the temperature distributions in roll and strip during rolling process

Abstract

Estimation of the temperature distribution in roll and strip is important for the modeling of rolling process. A number of numerical and analytical methods have been proposed in the literature for the estimation of temperature distribution in rolling. This work proposes a simplified and faster semi-analytical method. A finite element method code is used for the estimation of friction and plastic deformation powers based on partially converged solutions. These powers form inputs to analytical temperature prediction modules. The heat partition between rolls and strip is accomplished by matching the interface temperatures obtained from the temperature modules of strip and roll. The proposed method is validated from the experimental results available in literature, and a good agreement is found. Some parametric study has been carried out based on the proposed method.
