Abstract

Ein Verfahren zum Walzen von Stahlprofilen, insbesondere in einem Universal-Trägerwalzwerk, mit einer wechselweisen X- und H-Walzung sowie gezielter Kühlung des Stahlprofils beim Walzen, ermöglicht mit einfachen Mitteln und geringem Aufwand eine gleichmäßigere Temperatur über den Querschnitt eines gewalzten Stahlprofils nach dessen Abkühlung, wenn bei der Vorwalzung mit einem X-Kaliber auf jeder Seite des Stahlprofils an den Verbindungsstellen von Steg und Flansch eine Kühlwasserrinne ausgebildet wird.

Figure 00000001
A method for rolling steel profiles, especially in a universal carrier rolling mill, with alternating X and H rolling and targeted cooling of the steel profile during rolling, enables a more uniform temperature over the cross section of a rolled steel profile after it has cooled down with simple means and little effort , if a cooling water channel is formed on each side of the steel profile during the pre-rolling with an X-caliber.
