EUROPEAN STEEL TECHNOLOGY AND APPLICATION DAYS 2017 - ESTAD 2017

Ten years back SMS group has launched its X-Shape flatness measurement system for cold rolling mills. The core component of X-Shape is the flatness measuring roll developed by SMS group. Its outer appearance can hardly be distinguished from a conventional deflector roll, but it is the sophisticated technology inside that makes the difference. Main features are - state-of-the-art, four-hole measuring roll, - the roll surface remains closed, measurement without leaving any marks on the material surface, - maintenance-free signal and power transmission technology, - measuring width up to 3,000 millimeters with a maximum of 96 sensors, - model-based raw signal evaluation. The consistent development of the robust, low-maintenance, and cost-efficient X-Shape system led to a high precision flatness measurement and control. Since 2009, SMS group has delivered more than 50 X-Shape measuring rolls to customers around the world. Operational results from various cold rolling mills will be displayed as well as further developments driven by this broad experience, e.g. X-shape flatness measurement for hot rolling mills. The X-Shape system is an integral part of the X-Pact® electrics and automation for cold and aluminum rolling mills supplied by SMS group. X-Shape can be installed in new plants or can easily be retrofitted in existing facilities. Furthermore X-Shape measurement and control has been provided as technology package for improving strip flatness in existing cold rolling mills.
