Frequently Asked Questions
Soft Rolling Mode prevents the rolls from opening completely during weld seam passage. If the force is under 2000KN, the seam passes directly; if over, it reduces to 2000KN, ensuring the roll surface is not damaged while maintaining production speed.
The mill utilizes a specialized positive and negative bending system of the work rolls, which allows for precise adjustment of the strip profile to eliminate waves and ensure absolute flatness.
We utilize world-leading Siemens or ABB speed control devices for the driving system, paired with Siemens/ABB PLC controllers and intuitive touch-screen HMIs for basic automation.
Yes, the mill is designed for versatility. Depending on your process requirements, it can be configured for either wet or dry skin passing, and it comes equipped with high-pressure water systems for wet applications.
The system includes four core automatic controls: Automatic Constant Rolling Force (AFC), Automatic Constant Elongation (AEC), Automatic Position Control (APC), and Automatic Constant Tension Control (ATC).
The bending roll system is powered by a high-precision servo control system, allowing for rapid and accurate adjustments to the roll profile during operation.
