Abstract (en)
[origin: WO2022248102A1] The present application relates to a system (1) and a method for the thermomechanical rolling of long semifinished steel products (2), comprising a first rolling device (5); a second rolling device (7), arranged downstream of the first rolling device (5) in the transporting direction; optionally a first cooling device (6), arranged between the first and second rolling devices (5, 7); a first thermomechanical sizing block (11), arranged downstream of the second rolling device (7) in the transporting direction; a second cooling device (9), arranged between the second rolling device (7) and the first thermomechanical sizing block (11, 11.1); a cooling-bed, ring-laying and/or coil-winding device (16), arranged downstream of the first thermomechanical sizing block (11) in the transporting direction; a third cooling device (14), arranged between the first thermomechanical sizing block (11) and the cooling-bed, ring-laying and/or coil-winding device (16); and also a structure-sensor device (17), which is arranged between the first thermomechanical sizing block (11) and the cooling-bed, ring-laying and/or coil-winding device (16) and can be used for determining directly in the ongoing process a martensitic structure, in particular a proportion of martensite in percent by area (% by area), in the thermomechanically rolled long semifinished steel product or in the steel product (3) in the form of a wire or bar.
