FLATNESS MEASURING AND MEASURING OF RESIDUAL STRESSES FOR A METALLIC FLAT PRODUCT |
摘要 |
A method and apparatus for flatness measuring and measuring of residual stresses in a metallic flat product (1): The method includes bending the flat product (1) in a bending device (3) such that a planar flat product (1) forms an arc (5) with a target bending radius r0 after bending; measuring the contour and the actual bending radii r(y), in the region of the arc (5) of the bent flat product (1) at a plurality of positions along the width direction of the flat product (1); and determining the flatness of the flat product (1) taking into account the measured contour of the bent flat product (1). |
