Abstract

Um ein Verfahren zum Richten von gewalztem Profilstahl zu schaffen, das den Materialfluß in der Herstellung von Profilstählen nicht beeinträchtigt sowie ein qualitativ hochwertigen, eigenspannungsarmen Profilstahl liefert, wird erfindungsgemäß vorgeschlagen, daß der zumindest während des Richtens eine über seinen Querschnitt weitgehend homogene Temperaturverteilung aufweisende Profilstahl bei einer Temperatur im Umwandlungsbereich Ar1 bis Ar3 gerichtet wird.
