Abstract

Abstract A lot of problems arise even recently concerning the control of flatness and profile of rolled strip in industrial circumstances. In the course of planning of the cold-rolling technology of geometrically true strip that is exempt of internal deformation stresses — i.e. flatness strip — it is necessary to take into consideration the elastic and thermal deformation of working rolls, the basic sheet-metal forming of rolls, the existing crown of basic material as well as the wearing of the rolls. A measurement method by which the shape of strip can exactly be measured is necessary for performing the control. In the present phase of my research work, a measurement device has been developed by means of which the given problem can be solved for the time being in experimental circumstances.
