Abstract

Es wird ein Verfahren zur kontinuierlichen Herstellung mindestens eines, zumindest in einem Teilabschnitt (10.1, 10.2) gehärteten Stahlprofils (15). Um flexibel auf unterschiedlich ausgebildete Teilabschnitt (10.1, 10.2) reagieren zu können, schlägt die Erfindung vor, dass beim zweiten Erwärmungsschritt die zweiten Gasbrenner (14) in Reihen (r1, r2, r3, r4) in Bandlaufrichtung (16) des Profilstrangs (10) und in Spalten (s1, s2, s3, s4) quer zur Bandlaufrichtung (16) des Profilstrangs (10) angeordnet sind und angesteuert werden, den Teilabschnitt (10.1, 10.2) am Profilstrang (10) über Ac3 zu erwärmen.A method is used for the continuous production of at least one steel profile (15) hardened at least in a partial section (10.1, 10.2). In order to be able to react flexibly to differently designed subsections (10.1, 10.2), the invention proposes that, during the second heating step, the second gas burners (14) in rows (r1, r2, r3, r4) in the strip running direction (16) of the profile strand (10 ) and in columns (s1, s2, s3, s4) are arranged transversely to the strip running direction (16) of the profile strand (10) and are controlled to heat the section (10.1, 10.2) on the profile strand (10) via Ac3.
