Abstract (en)
[origin: EP0049425A2] 1. Method for the rolling of stress-free rolled strip through thermal influencing of the diameter of the rolls by means of regulation of their axial temperature distribution through acting on the rolls with a cooling, lubricating and/or cleaning liquid, wherein quantity, pressure or temperature of the liquid is altered in dependence on partial tension stresses determined in zones lying in transverse direction of the strip behind the last stand in that two liquids of different temperatures, the partial quantities of which are regulable in dependence on the determined partial tension force, for each zone are conducted, preferably settable in their width of impingement, to at least the roll stand arranged upstream of the place of measurement of the partial tension stresses, characterised thereby, that a first liquid, which is kept at a first temperature, is conducted at settable constant quantity flow to the rolls and that the quantity flow of the second liquid, which displays a lower temperature and is conducted additionally to at least the working rolls (2, 3), is regulable zone by zone in dependence on the determined partial tension stress.
