Forming of band curvature in asymmetrical rolling process

Nov 30, 2004· The data shown in Fig. 6, Fig. 7, Fig. 8, Fig. 9 indicate that asymmetric rolling with the use of asymmetry factor R g /R d =0.95 and 0.99 causes bending of the band exiting the roll gap. The radius of band bending is strictly dependent on the applied asymmetry factor and band shape, H 0 /R.Band curvature values obtained by using the FORGE2 program differ quantitatively from the band curvatureget price

Prediction and control of front-end curvature in hot

The purpose of this study is to predict the front-end curvature in hot strip finishing mills and to prevent it by controlling the rolling conditions. A theoretical model based on the slab method is developed for predicting the front-end curvature by taking into account the entrance angle of the strip, the friction condition and the back tension.get price
