Paper Title:
Prediction of Rolling Force during Temper Rolling
  Abstract

In temper rolling thickness reduction is small (0,5 – 2%) and the elastic deformation of the work roll should be taken into account. During finishing rolling, classical cold rolling theories fail to predict the roll flattening and thus the rolling force. Numerous different mathematical models have been developed for temper rolling process. However, often the non-circular theories are computationally expensive and the range of usability is questionable. In this study, elasto- plastic finite element analysis, laboratory rolling tests and inverse computing from skin pass mill process data has been carried out. The aim is to find the roll shape, contact length and the rolling force to create a simplified model for controlling of temper rolling. In addition, the ability of different skin pass rolling theories has been compared with measured process values.
