Title: Control of surface evenness for obtaining even cold strip
IPC: B21B37/76
Filed: 2000-03-14
Abstract: The invention relates to a method for rolling a strip in a strip rolling mill which has at least two roll stands or an individual stand with upper and lower, optionally adjustable working rolls respectively, said rolls being optionally supported indirectly on support rolls or with intermediate rolls. At least one pass is rolled in said rolls in order to modify the state of the rolled strip. A target distribution of stresses or any target form of unevenness is predetermined for the rolled strip and compared with the actual distribution of stresses and the mechanical or physical control elements are employed in such a way as to minimise the difference between the predetermined and actual distribution of stresses as far as possible. In addition to the actual distribution of stresses in the hot strip, the distribution of temperature over the width of the strip is determined and used to calculate the distribution of stresses which would be present after the strip has cooled if the strip were free of stresses in the hot state with the distribution of temperature that exists behind the roll gap and this temperature-induced distribution of stresses is used to correct the actual stress before this is compared with the target form of unevenness.
