A roll-stack contact mechanics model to predict strip profile in rolling mills with asymmetric, continuously variable crown rolls

F Zhang, A Malik - Journal of manufacturing science …, 2018 - asmedigitalcollection.asme.org
Introduced is an efficient new model to compute the roll-stack deflections and contact
mechanics behaviors for metal rolling mills with asymmetric roll crowns. The new model
expands the simplified mixed finite element (FE) method to consider complex antisymmetric
contact conditions of continuously variable crown (CVC) roll diameter profiles designed for
use with work-roll (WR) shifting on four-high mills, and intermediate-roll (IR) shifting on six-
high mills. Conventional roll-stack deflection models are either more computationally …
