Roll Contour Design of 4-high Mill with Variable Crown by Axial Shifting

The gap crown between two work rolls of plate mills and the strip shape can be adjusted by axial shifting of the work rolls, both of them have a special contour. By the research on the function of the work roll contour. especially on the 3 power series function and the CVC roll contour function. a way to determine the contour parameters was found.The difference between CVC & UPC work rolls and the application of them was discussed.
