Long Rolling Impact Controller

The Long Rolling Impact Controller by Primetals Technologies is engineered to manage the impact of the product front end, particularly in high-speed finishing mill stands. When the front end of a billet impacts the mill, it can cause a speed drop followed by oscillations during speed recovery. Conventional compensation methods, which apply a fixed percentage of the rolling speed reference, often fail to adapt to process variations such as changes in the temperature of the billet’s front end.

This advanced system eliminates such inefficiencies by measuring the impact drop for every billet and dynamically adapting to process-specific requirements. The Long Rolling Impact Controller generates optimal compensation in real time, ensuring smooth threading and consistent rolling. Moreover, it integrates seamlessly with existing drive systems, eliminating the need for manual adjustments. This task is often overlooked during continuous rolling operations. The Long Rolling Impact Controller supports various automation platforms, making it a versatile solution for both new and existing plants.

The controller is equipped with a smart control system that measures the impact drop for every billet. This feature allows the system to adapt and generate optimal compensation based on real-time process requirements. It can be integrated into existing drive systems, making it a flexible solution for plants that want to enhance their current operations without replacing existing infrastructure. The system automates the task of measuring and adapting impact compensation, which is often a complex and time-consuming task for operators. This automation helps maintain consistent rolling conditions. The Long Rolling Impact Controller feature is available as an independent software package, which can be implemented in existing plants and automation platforms.

Benefits of the Long Rolling Impact Controller

• Enhanced rolling stability: minimizes speed oscillations, ensuring stable rolling conditions and reducing the risk of cobbles. The Long Rolling Impact Controller furthermore improves the minimum tension control conditions.
• Support product quality: consistent speed control leads to constant high product quality and reduced defect rates.
• Operational efficiency: reduces the need for manual adjustments, allowing operators to focus on other critical tasks, thereby improving overall productivity.
• Simplified operations: automates the measurement and adaptation of impact compensation, reducing complexity and manual intervention.
• Flexible integration: can be implemented as an independent software package compatible with existing drive systems and automation platforms.
