Long Rolling Minimum Tension Controller

The Long Rolling Minimum Tension Controller is an innovative control system designed to address the challenges of long rolling processes in steel production. By ensuring precise stock control and stable rolling conditions, the Minimum Tension Controller enhances product quality while optimizing production processes. This advanced system provides invaluable tools for production managers, operators, and maintenance engineers, enabling seamless operations and improved outcomes.

The Long Rolling Minimum Tension Controller is engineered to maintain minimal tension between continuous mill stands, particularly in the roughing and intermediate sections where stock is thicker. This innovative system utilizes advanced algorithms to compensate production disturbances such as billet temperature variations and roll wear, ensuring strict size tolerances and stable rolling conditions. By delivering precise speed references to main stand drives, the Minimum Tension Controller guarantees size tolerance from the very first billet, making it a perfect solution for rolling high-grade, costly products with limited billets per order.

Benefits of the Long Rolling Minimum Tension Controller

• Enhanced product consistency: guarantees size tolerance from the first billet, minimizing waste and improving product uniformity, ensures proper distribution of the stand load.
• Operational stability: mitigates disturbances caused by temperature variations and roll wear, ensuring smoother mill operations.
• Cost efficiency: reduces the need for manual adjustments, saving time and operational costs.
• Reduced downtime: maintains optimal tension and compensates for disturbances, minimizing operational interruptions and increasing yield.

The Long Rolling Minimum Tension Controller Offers Several Advanced Features to Optimize Rolling Operations

• Interstand tension reduction: real-time torque monitoring and speed adjustments ensure minimal tension levels across roughing and intermediate mill stands, stabilizing rolling conditions and maintaining consistent stock size.
• Configurable rolling schedule: allows flexibility in adapting to various rolling scenarios, such as edger pass selection between loaded stands in section mills.
• Independent software package: available as a standalone software solution, it integrates effortlessly into existing automation platforms.
• Proven reliability and performance: successfully implemented in facilities worldwide, including installations at BGH (Germany & Poland, 2023), Böhler Voestalpine (Austria, 2023), JSW Steel (India, 2022), ArcelorMittal (Poland, 2019), and Walsin Lihwa Corp. (China, 2022).
