Check rail support plates made of steel for fastening rails are important constructional elements for track systems. Those check rail support plates are manufactured in the rail mill at voestalpine Schienen GmbH in Leoben-Donawitz, Austria. Starting products are billets which are rolled to preliminary sections in a break-down rolling stand. After passing the roller table they are rolled to the finished product in the ultra-flexible rail (UFR) mill. Due to changed rolling conditions after the modernisation of the rail mill it was necessary to slightly modify the roll pass design. Therefore, finite element simulations with software Deform 3D were made for all rolling stands of the UFR mill. With respect to the results of these simulations like rolling force, rolling torque and material flow the reductions per pass as well as the roll grooves were changed marginally.
