A New Rolling Process for Strips with a Defined Cross Section

A new rolling process is being developed for producing cold rolled strips with a defined cross section. These strips feature differences in thickness up to 50% perpendicular to the rolling direction. A special roll system is used to achieve a material flow exclusively in the direction of the strip width. As a consequence the strip width is increased significantly. In this way a wide variety of different cross sections can be produced. The range of application for these kind of strips cover novel load-adapted and load-optimized structures with different thicknesses, e.g. special profiles and special section tubes.
