Abstract
The invention concerns a method and a plant for producing flat rolled products, in order to obtain strips having a multiple crown transverse profile that subsequently have to be divided in a longitudinal direction into strips of a smaller width; the method provides a rolling step carried out in a rolling mill comprising roughing stands and finishing stands equipped with respective work rolls, in order to supply a strip of a determinate width.
Claims12
Method for producing flat rolled products, in order to obtain strips with a multiple positive crown transverse profile, which provides a rolling step carried out in a rolling mill comprising finishing stands equipped with respective work rolls, in order to supply a strip of a determinate width, wherein at least the work rolls of at least the last finishing stand are provided to have a profile with multiple negative crown, wherein the number of crowns present in the profile of the work rolls is correlated to the number of portions into which the rolled strip produced is subsequently divided in a longitudinal direction.
Plant for producing flat rolled products, in order to obtain strips with a multiple positive crown transverse profile, comprising at least one unit of finishing stands with work rolls, wherein in order to obtain a strip which, in a subsequent step and in a moment that follows the end of the rolling, will be longitudinally sectioned into multiple portions, at least the last finishing stand of the finishing unit comprises work rolls having a multiple negative crown profile, wherein the number of crowns present in the profile of the work rolls is correlated to the number of portions into which the strip will be divided.
Plant as in one or the other of claims from 6, configured to operate in either one and/or the other of endless, semi-endless or coil-to-coil modes.
Work roll for a finishing stand of a rolling plant for strips, comprising a multiple negative crown profile, wherein the number of crowns present in the profile of said work roll is correlated to the number of portions into which the strip produced is intended to be divided longitudinally.
