摘要： A method for flattening steel strip by cold rolling the strip by passing it through at least two cold rolling mill stands each having work rolls. A first of the mill stands has work rolls having local rigidity K significantly different from a second mill stand, wherein the local rigidity K is calculated in Kgf/mm/mm accordance with an equation. Also a six high mill for flattening steel strip has an entry side where the strip enters the mill and an exit side where the strip exits the mill. The mill comprises a pair of driven backup rolls disposed on the entry side of the mill, a pair of horizontal support rolls disposed on the exit side of the mill and a pair of small diameter work rolls, the work rolls having an entry side face and an exit side face. The work rolls are disposed between the pair of backup rolls and the pair of support rolls. The entry side face of the work rolls is in engagement with the backup rolls during operation and the exit side face of the work rolls is in engagement with the support rolls during operation.
