Skin-passed hot strip offers you these advantages: Most importantly, this process helps you attain perfect strip flatness. It also harmonizes the yield points and prevents the flow and break lines that can occur during uncoiling. Furthermore, the downstream pickling process is easier because skin-passing breaks up the scale layer. Recoiling provides a better coil shape. Included in the process is cutting off the head and tail ends of the strip as well as the off- gauge materials. To safely handle today’s new materials – especially high- strength steels – the hot strip skin-pass mill (HSPM) comes with technology designed for materials with the “spring effect”. Our solution for hot strip skin-passing is a mill in 4-high design – optionally with CVC®plus – complete with coil preparation station and pay-off reel on the entry side as well as one tension reel, an inspection table, plus a hydraulic shear on the exit side. To ensure top strip quality and yield, our mills achieve positive and negative work-roll bending. They also include our X-Shape flatness measurement and control system.
