1. A strand-guiding section of a continuous casting line,
wherein the strand-guiding section is arranged downstream of a continuous casting mold of the continuous casting line,
wherein the strand-guiding section has at least one strand-guiding roller for supporting a metal strand that is cast with the continuous casting mold,
wherein the at least one strand-guiding roller is mounted in roller bearings in the strand-guiding section,
wherein the strand-guiding section has at least one sensor device, which in turn has at least one vibration sensor which is acoustically coupled to the at least one strand-guiding roller or the roller bearings thereof, by means of which vibrations occurring when the at least one strand-guiding roller is rotated in the roller bearings are detected,
wherein the at least one sensor device has an interface via which vibration data (SD) derived from detected vibrations are transmitted to an evaluation device,
wherein the at least one strand-guiding roller is cooled internally by cooling water supplied to the at least one strand-guiding roller and the at least one vibration sensor is directly and acoustically coupled to the cooling water to detect the vibrations occurring when the at least one strand-guiding roller is rotated via direct contact with the cooling water.
