Abstract

The research aims to establish a scientific basis for the required number of tie bands used in fastening stainless-steel coils in steel manufacturing lines. Strain gages were installed on the steel tie bands and stresses were measured during the banding and delivery procedure of coil rolls in the recoiling field. Our results showed that the springback stress was low when the coil thickness was below 3.0 mm, but increased significantly with increased thickness. The comparison between the measured springback stress and the theoretical springback stress formula developed in this study showed a good correlation coefficient of 0.945, thus demonstrating the usefulness of the formula in predicting the springback stress. Our results showed that the current factory standard on the number of tie bands did not significantly consider the increase in the springback force with increased coil thickness.
