Revamping of the skin pass mill The skin pass has been already revamped in the past. Originally, there were only one work roll diameter of 440mm and backup rolls of diameter 1100mm. The first revamping in 1998 was consisting of : • Implement two work rolls diameters, 440400mm and 560520mm • Backup rolls reduced to 1000
Smaller work roll diameters reduce the rolling force when skinpassing highstrength steel strip. Larger work rolls are ideal for processing very mild steel grades with a high rolling force. ... the hot strip skinpass mill (HSPM) comes with technology designed for materials with the "spring effect". Our solution for hot strip skinpassing ...

The punch roller is used to control the location of the tangent point and to maintain the flat shape of the uncoiled sheet before passing through the bridle roll. During the uncoiling process, the position of the punch roll is fixed, and the location of the tangent point tends to move toward the peak of the coil for decrease in coil diameter.
For the sake of researching the mechanism of relative slipping happens between the bridle roll and strip when the speed of the skin pass mill (SPM) is increased, a mathematical model for relative sliding between the strip steel and the bridle roll was built. At the same time, a quantitative parameter named "the strip slip risk ratio" was proposed.
