A finite element-based on-line model for the prediction of deformed roll profile in flat rolling

Abstract

A sound model for the prediction of the deformed roll profile during rolling is vital for the precision control of the profile and shape of the product. In this paper, the prediction accuracy of the conventional models is examined, using the predictions from the finite element model as benchmarks. Then, it is shown that a new, precision on-line model can be developed on the basis of the finite element model. The prediction accuracy of the new model is demonstrated through comparison with the predictions from the finite element model. © 2007 ISIJ.
