During tandem hot rolling (THR), the rolling force plays an important role in strip shape control, but the influence mechanism of the rolling force on the strip shape is still currently unclear. This paper proposes a novel 3D multi-stand coupled thermo-mechanical finite element (FE) model for the THR developed employing a segmentation modelling strategy and data transfer technologies. This developed FE model has been validated by industrial experiments. Besides, the effects of rolling force on the strip shape (including strip crown and flatness) in the THR have been quantitatively studied. Res...

Intermediate roll shifting (IRS) is widely used for improving the strip shape in the six-high tandem cold mill, but most related studies are limited to a single stand. To fill the knowledge gap, a three-dimensional (3D) multi-stand elastic–plastic finite element (FE) model was developed for a continuously variable crown (CVC)-6 tandem cold mill using data transfer, which was then validated by industrial experimental results. Based on this FE model, the effects of the IRS on the strip crown, strip flatness, loaded roll gap profile and contact normal stress between rolls at each stand were qua...

The strip shape inheritance model is widely applied to improve the strip shape quality in tandem cold rolling (TCR). However, the inheritance mechanism is still currently unclear. To bridge this gap, this paper presents a new numerical method for calculating the strip crown inheritance factor. In addition, the effects of the entry strip crown on exit strip crown and flatness were quantitatively analysed at each stand in the TCR using a novel three-dimensional (3D) multi-stand elastic–plastic finite element (FE) model. The results show that the strip crown inheritance factor increases slowly ...
