Prediction of Steady-state Strip Profile in Flat Rolling
- Prediction of Steady-state Strip Profile in Flat Rolling
- Date Issued
- A prerequisite for automatic process set-up and control in a hot strip mill, in a cold rolling mill, and in a plate mill is to acquire a precision mathematical model for the prediction of the strip profile and the residual stresses. In this paper, an issue is raised regarding the importance of taking into account the effect of post-deformation. Also, demonstrated is how to rigorously implement it into the calculation of the strip profile and residual stress profile. The validity of our post-deformation model is verified through comparison with predictions from Finite Element simulation and also with actual measurements.
