Abstract
A method of rolling an elongated workpiece in the form of a sheet or strip and of reducing edge drop during rolling comprising passing the workpiece through at least one pair of opposed work rolls which comprise an arbor and a hollow sleeve shrink-fitted over the arbor and having end portions defining, between the arbor and sleeve, a cavity providing a self-compensating flexible roll end portion which is placed over and extends beyond a longitudinal edge of the workpiece during rolling. Preferably, the shrink-fitted portion is provided with maximum radial stress at the middle thereof and decreasing toward the ends of the shrink-fitted zone. The work rolls may be backed up with self-compensating backup rolls to further improve uniformity of the rolled workpiece by reducing crown variation thereof. Positioning of the rolls is accomplished by axial shifting.
