Frequently Asked Questions
A Skin Pass Mill is used to remove the yield point elongation (Lüders bands), improve surface flatness, and control the final mechanical properties of the metal strip.
It prevents roll surface damage by reducing the rolling force to 2000KN or less when a weld seam passes, allowing it to pass without needing to fully open the rolls.
Yes, the mill is designed to support both wet and dry skin passing based on specific customer requirements and material standards.
We use industry-leading Siemens or ABB PLC systems and full digital inverter speed control to ensure maximum stability and precision.
Flatness is managed through a positive and negative bending system applied to the work rolls, allowing for precise adjustment of the strip profile.
The system includes a medium-pressure hydraulic station, a high-pressure servo station, high-pressure water systems, and anti-crimping/anti-cross breaker rolls.
