ROLLING METHOD FOR A PROFILE IN PARTICULAR A FLANGE PROFILE AND UNIVERSAL ROLL STAND CORRESPONDING TO THAT METHOD

摘要

PURPOSE: Provided is a rolling method for a profiled section and a universal roll stand for performing this method by which the profiled section can be rolled in an improved way, in particular, with reduced tolerances. CONSTITUTION: The universal roll stand for rolling profiled sections comprises: horizontal rolls(2,3) and vertical rolls(4,5) having a vertical roll center(6,7); first control elements(8,11) configured to adjust the horizontal rolls, based on a preset nominal horizontal roll gap(h*), toward one another to form an actual horizontal roll gap(h), wherein the horizontal rolls are adjusted with the preset nominal horizontal roll gap symmetrically relative to the vertical roll centers; second control elements configured to adjust the vertical rolls toward the horizontal rolls to form actual vertical roll gaps, wherein the first control elements are hydraulic cylinder units(8,9) that are configured to vertically adjust, based on an additional nominal value, the horizontal rolls in the same direction by the same amount.
