The mill is simulated by beams (rolls) on the infinite elastic half space (between rolls and strip). The roll deflection and indentation are calculated using the influence coefficients and Boussinesq's equations respectively. The roll contours in the contact zone can be expressed in terms of the influence coefficient and indentation matrices.

Hot Rolling - an overview | ScienceDirect Topics

3.1 Key Feature of Process Control: Detection of Periodic Defects Rolls and rollers are the most heavily used parts of a rolling mill. Due to wear from contacting hot material with great force, their lifetime is limited. Although rolls are refurbished in the roll shop regularly, they occasionally crack before the end of the usual production cycle.
