  • Method and device for heating a steel blank for hardening purposes
    Patent number: 11149327
    Abstract: A method and a device for heating a sheet metal blank or a formed sheet metal component above the austenitization temperature for the purpose of quench hardening, wherein the dew point of the furnace atmosphere is set to ?15° C. to 15° C., preferably to ?10° C. to 10° C., in particular for the formation of a loosely adhering oxide skin, for controlling an oxide skin on the sheet metal or component coated with a metallic corrosion protection layer or an uncoated sheet metal or component.
    Type: Grant
    Filed: May 24, 2019
    Date of Patent: October 19, 2021
    Assignees: voestalpine Automotive Components Cartersville Inc., Bayerische Motoren Werke Aktiengesellschaft

  • Detection of contamination on steel parts using ultraviolet light
    Patent number: 11047804
    Abstract: There is disclosed methods and apparatus for detecting contamination on cold-formed steel parts prior to subsequent press-hardening in which such contamination may be problematic, and also for detecting contamination on cold-forming machinery that might be transferred to cold-formed steel parts during cold-forming. In some aspects, the disclosure also relates to methods and apparatus for detecting splits or cracks in cold-formed steel parts prior to subsequent press-hardening. The methods and apparatus make use of ultraviolet light to detect contamination or to detect splits or cracks.
