Title:Wear generation during cold strip rolling - a model based analysisAuthor(s):Daniel Strasser, Martin Bergmann, Bas Smeulders, Dieter Paesold, Konrad Krimpelstätter, Peter Schellingerhout, Alexander Kainz, Klaus ZemanAbstract:In order to study the generation of wear during cold rolling and the impact of important influencing factors, a mathematical model for the prediction of the amount of wear that is extracted from the strip surface was developed. Based on a locally distributed implementation of Archard’s equation combined with a fractional film defect model that reflects the lubrication efficiency of the interface between work roll and strip, the model predicts the strip wear volume that is generated during cold strip rolling. The model has been applied to predict the strip wear generated in typical rolling schedules on a production mill. Based on these schedules, the influence of significant rolling parameters (e.g. strip material grade, thickness reduction, etc.) on the amount of generated strip wear was examined. The developed wear model significantly contributes to a better understanding of the interrelations between rolling parameters and the strip wear volume generated during cold strip rolling. It allows for the prediction of strip wear generated in different stands of a rolling mill depending on rolling parameters, lubricant properties, and the rolled product.Booktitle:Proceedings of the 3rd European Steel Technology and Application Days ConferenceISBN:978-3-200-05196-6Page Reference:page 2141-2150, 10 page(s)Publishing:6/2017
