Abstract

Das erfindungsgemäße Verfahren ermöglicht auf kostengünstig durchführbare Weise, die Eigenschaften von hochfestem, gut verformbarem Warmband auf den jeweiligen Verwendungszweck hin gezielt zu optimieren. Dabei wird ein Stahl verarbeitet, der niedrige, unter-peritektische Gehalte an Kohlenstoff besitzt. Dieser Stahl wird zu Dünnbrammen oder Band vergossen, mit einer mindestens 150 K betragen Abkühlgeschwindigkeit auf eine zwischen 500 °C und 700 °C liegenden Zwischentemperatur abgekühlt und gehaspelt. Durch die Wahl der Haspeltemperatur lassen sich dann die Eigenschaften des erhaltenen Warmbands gezielt einstellen.
