Frequently Asked Questions
Hydraulic Automatic Gauge Control (AGC) ensures precise thickness uniformity across the entire strip by adjusting the roll gap in real-time based on feedback and mass flow data.
A reversing mill passes the material back and forth through the same stand to achieve the desired thickness, offering higher flexibility for different gauges compared to a multi-stand tandem mill.
The PLC (Programmable Logic Controller) manages the complex synchronization of DC speed control, tension loops, and hydraulic systems to ensure stable and repeatable production.
We utilize positive and negative bending of working rolls, as well as intermediate roll shifting, to compensate for roll deflection and maintain a flat strip profile.
Yes, our system is designed for compatibility. We also offer Revamping Services and Spare Parts to upgrade existing lines to modern digital standards.
Segmented cooling allows for targeted temperature management across the roll surface, preventing thermal crowning and ensuring uniform material properties.
