Abstract: In a method for the spectral analysis of a metal coating layer deposited on the surface of a steel strip, the strip is moved along an arc of the outer surface of a rotating roller with a cylindrical wall guiding the strip by contact. An ablation laser beam is guided into an internal cavity of the cylindrical wall to be placed in optical incidence under a normal axis on the outer surface of the roller on a targeted contact point of the strip and the roller. The beam passes through the wall via a wall opening, which is transparent to the beam. A plasma spectral emission distribution from the laser ablation to the contact point is collected by optical feedback in the direction of the normal axis on the outer surface of the roller and through the opening in order to be guided towards a spectral measurement unit. The normal axis on the outer surface for the optical incidence and feedback is placed in synchronous rotation with the roller.

Abstract: The invention relates to a device for strip guidance in a hot medium, comprising a deflection roller (3, 38) mounted on supporting arms (1, 2, 34, 37, 54, 57) and a carrier device holding the supporting arms (1, 2, 34, 37, 54, 57). The device is characterized in that one of the supporting arms (1, 2, 34, 37, 54, 57) is mounted on the carrier device by means of a floating bearing (5), wherein the floating bearing (5) allows the mounted supporting arm on the carrier device to move parallel to the longitudinal direction of the deflection roller (3, 38), and in that an elastic counter element (12), which acts parallel to the longitudinal direction of the deflection roller (3, 38) upon the supporting arm (1, 2, 34, 37, 54, 57) mounted on the floating bearing (5), is present and counteracts an increasing distance between the supporting arms (1, 2, 34, 37, 54, 57). In this way, the technical problems of offsetting a temperature-induced length change of the deflection roller and avoiding an uncontrolled movement of the system are solved.
