Abstract

Die Erfindung betrifft ein Verfahren und eine Anlage zum Wärmebehandeln von Blechen, Bändern oder Drähten, in einer Charge in Form von mindestens einem Coil in einem Ofenraum unter Schutzgas, wobei eine erste Charge (3) in mindestens einem ersten Ofenraum (1a) während mindestens einer Heizphase aufgeheizt und während mindestens einer Abkühlphase abgekühlt wird, wobei in mindestens einem zweiten Ofenraum (2a) eine zweite Charge (4) wärmebehandelt wird, dadurch gekennzeichnet, dass aus jedem Ofenraum (1a, 2a) ein Schutzgasstrom abgeführt, einem Schutzgas- Wärmetauscher (14) zugeführt und in einem Kreislauf dem Ofenraum (1a, 2a) wieder zugeführt wird, dass die Schutzgasströme aus dem ersten und des zweiten Ofenraums (1a, 2a) in dem Schutzgas-Wärmetauscher (14) Wärmeenergie austauschen, um die erste Charge (3) abzukühlen und die zweite Charge (4) mittels der Abwärme der ersten Charge (3) aufzuheizen.
