Ultrasonic roll bite measurements in cold rolling – Roll stress and deformation [PDF]
Journal of Materials Processing Technology, 2017 In cold rolling of thin metal strip, contact conditions between the work rolls and the strip are of great importance: roll deformations and their effect on strip thickness variation may lead to strip flatness defects and thickness inhomogeneity. To control the process, several online measurements are usually carried out such as the rolling load ...
