Abstract (en)
[origin: US2006196243A1] The invention relates to a method for changing the configuration of a rolling mill including at least two working rolls and two back-up rolls, means for applying a clamping load and two sets of hydraulic cambering cylinders, at least of both working rolls. According to the invention, at least two types of working rolls (C 1 , C 2 ) are realised having, respectively a great diameter and a small diameter and the quarto configuration rolling mill is switched to a sexto configuration and conversely, the rolls with great diameter (C 1, C' 1 ) being used as working rolls in the quarto configuration and, in the sexto configuration, as intermediate rolls between each back-up roll and a roll with small diameter (C 2, C' 2 ) used as a working roll.
