Frequently Asked Questions
The Soft Rolling mode prevents roll surface damage during the passage of welded seams. If rolling force is below 2000KN, the seam passes directly; if above, the system automatically reduces force to 2000KN, ensuring protection without fully opening the rolls.
Flatness is managed through a sophisticated positive and negative bending system applied to the work rolls, allowing for precise correction of strip topography.
We utilize industry-leading Siemens or ABB PLC control systems paired with full digital inverter speed control and intuitive touch screen interfaces.
Yes, the mill is designed for either wet or dry skin passing depending on your process requirements, and it is equipped with a high-pressure water system for wet operations.
Downtime is minimized through quick automatic roll gap recovery, online automatic calibration, and rapid online roll changes facilitated by hydraulic locking.
These refer to the automatic control systems for Constant Rolling Force (AFC), Constant Elongation (AEC), Position Control (APC), and Constant Tension (ATC), ensuring perfect consistency during the rolling process.
