Stressometer Flatness Control System Case Study

This document describes how ABB's Stressometer flatness control system, featuring patented Extended Singular Value Decomposition (ESVD), replaced an obsolete competitor system at Outokumpu Nyby in Sweden to improve product quality and yield in stainless steel rolling. It highlights the system's ability to provide fully automatic, accurate flatness control for cold and hot rolling processes, minimizing waste and production errors.
