Frequently Asked Questions
The Skin Pass Mill is used to eliminate the yield point elongation of cold-rolled strips, improve surface flatness, and provide a specific surface finish (smooth or matte) to meet customer specifications.
It automatically adjusts the rolling force. If the force is under 2000KN, the weld seam passes directly; if it exceeds 2000KN, it reduces the force to 2000KN, avoiding the need to open the rolls and preventing surface damage.
Yes, the mill is designed to support both wet and dry skin passing processes depending on the specific material and quality requirements, equipped with a high-pressure water system for wet processes.
We utilize industry-leading digital inverter speed controls and PLC systems from Siemens or ABB, coupled with servo control for the bending roll system to ensure maximum precision.
Flatness is managed through a positive and negative bending system of the work rolls, which allows for precise adjustments to the roll profile during operation.
The system includes medium pressure hydraulic stations, high pressure servo stations, anti-crimping rolls, and anti-cross breaker rolls to ensure smooth strip flow.
