Abstract
A method for producing a dual-phase steel strip in a system having a finish-rolling train with a first stand group that includes at least one first finish-rolling stand, and a second stand group that includes at least one stand cooler. The system has a cooling section that includes a first cooling section group and a second cooling section group. Immediately following finish-rolling of a finish-rolled strip, the finish-rolled strip is fed to the second stand group, and force-cooled to a second exit temperature (TA) so that upon exiting the second stand group the strip has a predominantly austenitic structure. Once the force-cooling stops, a ferritic and austenitic structure forms in the finish-rolled strip during transport. The finish-rolled strip is force-cooled to a fourth exit temperature (TA) in the second cooling section group so that, upon exiting, the finish-rolled strip has a dual-phase structure composed of martensite and ferrite.
