Abstract

In a four-high rolling mill stand, with provision for bending the work rolls, at least one back-up roll has a convex crown around the roll body between 0.5 and 10 mm. in dia. At least one work roll, contacting the back-up roll, has a concave crown around the body, defined by the condition (I) where C(BUR) is the absolute value of the crown in dia. of the back-up roll and C(WR) an absolute value in crown in dia. of the work roll. In a six-high stand intermediate and work rolls are similarly cambered.
