Bridle Roll Unit Summary - Strip Metal Coil Processing

The hot mill's strategy is to get the relationship between crown and shape correct so that they will both come out right in cold rolling. If that sounds difficult, it is! The tension on the coil strand through the mill also affects the thickness reduction at the mill roll.
