Adequate cooling of the roll and strip is of considerable importance for mill designers, process engineers, and consumers. The purpose of this paper is to review recent heat‐transfer research of the cooling technology in the steel‐rolling process. The importance of roll and strip cooling on the thermomechanical treatment will be discussed with an assessment of the research on the corresponding heat‐transfer coefficients for various cooling systems currently used. Special laboratory apparatus resembling the cooling system used in steel mills has been developed to study the major parameters that control the cooling processes. Since the heat‐transfer coefficient is the most important indicator of the effectiveness of a cooling system, the coefficient under various roll‐cooling conditions is experimentally studied by the special apparatus and numerically evaluated by a finite difference technique.
