ABSTRACT:
A process of rolling steel in a reversing mill by passing the steel back and forth through the mill for a selected number of passes to achieve the desired thickness and on at least two early passes, each in a different direction, tapering the ends of the steel during taper passes by adjusting the roll gap, the roll gap adjustment (.DELTA.H) being a function (F(.DELTA.F.sub.m)) of the change in roll force (.DELTA.F.sub.m) above a lock-on force (F.sub.1) which lock-on force is established on the instant taper pass.
