Patent number: 8522586Abstract: The invention relates to a method for producing a sheet metal component. A hot or cold strip is electrolytically coated or coated in a smelting bath and the thus coated hot or cold strip is subjected to a flexible rolling process. During said process, sheet metal having various thicknesses of the flexibly rolled steel strips are produced due to various rolling pressures. Said invention is characterized in that in accordance with the thickness of the sheet metal after being rolled in a flexible manner or in accordance with the rolling pressure during flexible rolling, either the coating whilst being coated has various thicknesses, and in accordance with the rolling pressure with increasing rolling pressure that is expected, the thickness of the coating is thicker and/or the coating prior to or after the flexible rolling is subjected to a mechanical or chemical surface treatment for adjusting the desired emissivity or heat absorption capacity.Type: GrantFiled: January 31, 2008Date of Patent: September 3, 2013Assignee: Voestalpine Stahl GmbHInventor: Josef Faderl

Patent number: 8181331Abstract: The invention relates to a method for producing hardened structural parts from sheet steel. The method includes shaping at least one shaped part made of sheet steel provided with a cathodic corrosion protection coating, performing any required final trim of the shaped part and possibly any required punching, or the creation of a perforation pattern, subsequently heating the shaped part, at least over partial areas, under the admission of atmospheric oxygen to a temperature which permits austenizing of the steel material, and thereafter transferring the structural part to a mold-hardening tool and performing mold-hardening in the mold-hardening tool, wherein the structural part is cooled by the contact with and pressing by the mold-hardening tool and is hardened thereby.Type: GrantFiled: June 9, 2004Date of Patent: May 22, 2012Assignees: voestalpine Automotive GmbH, voestalpine Stahl GmbHInventors: Werner Brandstätter, Josef Faderl, Martin Fleischanderl, Siegfried Kolnberger, Gerald Landl, Anna Elisabeth Raab, Robert Vehof, Wolfgang Stall

Patent number: 7938949Abstract: The invention relates to a method for producing a hardened profiled structural part from a hardenable steel alloy with cathodic corrosion protection. The method includes applying a coating to a sheet made of a hardenable steel alloy, wherein the coating comprises zinc, and the coating further comprises one or several elements with affinity to oxygen in a total amount of 0.1 weight-% to 15 weight-% in relation to the total coating. After applying the coating, the coated sheet steel is roller-profiled in a profiling device, so that the sheet tape is formed into a roller-formed profiled strand. Thereafter, the coated sheet steel is brought, at least in parts and with the admission of atmospheric oxygen, to a temperature required for hardening and is heated to a structural change required for hardening. A skin made of an oxide of the element(s) with affinity to oxygen is formed on the surface of the coating.Type: GrantFiled: November 1, 2010Date of Patent: May 10, 2011Assignee: voestalpine Stahl GmbHInventors: Werner Brandstatter, Herbert Eibensteiner, Martin Fleischanderl, Josef Faderl, Gerald Landl, Anna Elisabeth Raab, Siegfried Kolnberger
