Title: Rolling method for preventing width camber
Inventor: TAKAHASHI ISAO
IPC: B21B1/22
Filed: 2001-07-04
Abstract: PROBLEM TO BE SOLVED: To provide a rolling method for preventing width camber which is suitable for manufacturing an aluminum sheet, a copper sheet, a steel sheet or the like. SOLUTION: The relationship between the circumferential speed ratio Rv of upper and lower work rolls 2, 3 and the amount of the width camber of a rolled sheet is examined beforehand and the width camber is prevented by selecting the Rv so as to cancel the width camber generated on the rolled sheet 1. Consequently, this method is applied to the rolled sheet 1 of an arbitrary material and size without deteriorating the surface quality of the rolled sheet 1. When the circumferential speed ratio of the upper and lower work rolls which is necessary to prevent the width camber of the rolled sheet is determined beforehand and the result is shown by a table, a drawing or a formula to the size of the rolled sheet, the selection of the Rv is performed rapidly and accurately.  It is effective to apply this method to the rolling until tailing off after rolling a prescribed length in the rolling of the final pass.
