Flatness Expert: Precision Strip Flatness Control System for Cold Rolling Mills

The Flatness Expert is a state-of-the-art solution designed to address the critical challenges of achieving and maintaining optimal strip flatness in cold rolling mills. As the demands for high-quality cold-rolled strip continue to rise, ensuring excellent flatness is not just a quality feature but a necessity for efficient and reliable rolling operations. The strip flatness control system from Primetals Technologies leverages advanced technology to provide precise control over the strip's flatness, ensuring uniform tensile stress distribution and minimizing the risk of strip breaks.

The Flatness Expert integrates advanced measurement systems to accurately assess tensile stress distribution, enabling precise control over strip flatness. It works seamlessly with various roll gap actuators, including tilting, work and intermediate roll bending, shifting, crowns, multi-zone cooling, hot edge sprays, and inductive roll heating. The system utilizes strategically positioned spray nozzles for work roll cooling, dynamically responding to shape control requirements. Sophisticated model-based control algorithms ensure fast response times, even at low rolling speeds, while feed forward control compensates for roll force changes to maintain consistent strip tension distribution. Pre-calculated model-based efficiencies enable immediate and precise control, leading to superior strip quality. The user-friendly interface provides intuitive tools for real-time monitoring and adjustments, independently of individual measuring rolls, enhancing operational flexibility and efficiency.

The Flatness Expert is the ultimate solution for precision strip flatness control in cold rolling mills, ensuring superior quality, operational efficiency, and cost-effectiveness.
