Abstract: A system for the thermomechanical rolling of long semi-finished steel products includes a first rolling unit; a second rolling unit, arranged downstream of the first rolling unit; a first thermomechanical sizing block, arranged downstream of the second rolling unit; a second cooling device, arranged between the second rolling unit and the first thermomechanical sizing block; a cooling-bed, ring-laying and/or coil-winding device, arranged downstream of the first thermomechanical sizing block; a third cooling device, arranged between the first thermomechanical sizing block and the cooling-bed, ring-laying and/or coil-winding device; and a structure-sensor device, which is arranged between the first thermomechanical sizing block and the cooling-bed, ring-laying and/or coil-winding device, and can be used for determining directly in the ongoing process a martensitic structure, in particular a proportion of martensite in percent by area, in the thermomechanically rolled long semi-finished steel product or in the steel product.
