THERMAL MODELING OF ROLL AND STRIP INTERFACE IN ROLLING PROCESSES: PART 1-REVIEW

Abstract

In rolling, the roll is used as a tool to deform the strip, resulting in rolling contact between the roll and strip and creating thermal resistance along the interface. A wide range of modeling approaches or correlations has been developed to study the interface heat transfer phenomena during rolling. In this paper the rationale and formulation of the most frequently adopted approaches in modeling of the roll-strip contact region are reviewed. The associated advantages and disadvantages of three major approaches are specifically discussed. The parameters involved in each approach are identified. The present paper is intended to provide the necessary information to assist investigations in understanding the intricacy of the contact problem encountered and the heat transfer parameters involved. In an accompanying paper (Part2\[1]), an illustration is given to show the appropriate way to model the contact region in the metal rolling process.
