    At the cold mill every time we change the thickness profile we also change the flatness. The cold mill roll gap should start out being set to the same profile as the crown of the incoming hot mill product. Then as the cold mill gap is adjusted to reduce the crown the coil also will come out flat--if the hot mill got the relationship between

    The rolls pull the material into the roll gap through a net frictional force on the material. Thus the net frictional force must be to the right in Fig. (5-3 b). This also means that the frictional force to the left of the neutral point must be higher than the friction force to the right. Although friction is necessary for

    the rolls are no longer useful either because of the small size (capacity loss) or the loss of roll hardness. Larger diameter rolls will process more tons before recorrugation and will have a deeper roll chill or hard working surface. Because of the better nip angle large diameter rolls are often used in

    ness of the backup rolls is specified as 64–68 HSC. The purpose of using the relatively soft backup rolls was to avoid the slippage of rolls and to improve the toughness and flexibility of the backup rolls. Since the backup rolls are driven by the work rolls normal pressure and tangential traction exist on the interface of the rolls.

Even though the cold mill itself may cause local buckles the majority of the local buckles are caused by the feed stock from the hot mill (Melfo et al. 2006). Therefore proper monitoring of the hot band profile and mechanical properties will be the first choice to reduce local buckles.
