  • Detailed description the embodiments
  • The schematic representation according to 1 shows a roller or a roller 1 , with left and right pins. The roller or roller body 2 has near-surface holes or blind holes 3 on. Such holes 3 can be made by known methods, such as spark erosion. The diameter and the length and the distance between the holes 3 to basic body surface depend on concrete application. The diameter of the hole depends, for example, on the optical waveguides used 4 from. These may be surrounded by a sheath made of stainless steel or another conventional protective coating. Furthermore, several optical fibers can also be used 4 in a hole 3 to be ordered. If so, they may be offset lengthwise in the holes 3 can be arranged, whereby the measurement accuracy can be further increased. For example, a single optical fiber may have a diameter of 0.1 mm-1 mm, but may also have smaller or larger diameters. The distance between the holes 3 parallel to the surface of the roller or roller 1 and / or parallel to the axis of rotation of the roller or roller 1 can be arranged, on the one hand depends on the material from which the roller or roller 1 is manufactured on the one hand and on the other from the mass or the pressure that rests on the surface. In the case of force or pressure measurement, the distance between the bore and the roller or roller surface may be less with a mass of several tons than with a smaller mass bearing on the roller or roller. In all cases, the distance of the bore from the roll surface should be less than 3 cm but greater than 1 mm. The distance must also be at least so small that the deformation of the roller or roller surface, by the pressure on her, even through the sensors 4 can be detected, that is, that also includes the sensors 4 mechanically deform yourself. Is the pressure or force distribution along the surface and the longitudinal axis of a roller or roller 1 known, so This can be adjusted so that the least possible wear on the roller or roller 1 and a conveyed or rolled strand. The forces that are relevant and measured, act substantially perpendicular to the surface of the rollers or rollers 1 ,
  • 2 also shows a roller 1' , in the near-surface holes 3 ' are arranged. The holes 3 ' go through the entire width of the body 2 ' and are determined by their position and size according to the arrangement in 1 intended. optical fiber 4 ' are in the holes 3 ' arranged so that they meander. This is over the entire width of the roller or roller 1 a temperature and force monitoring on the surface possible. Also in this embodiment, multiple optical fibers 4 ' within a hole 3 ' , possibly staggered, can be arranged.
  • In addition, the laying of the optical waveguide in the circumferential direction of the roller or roller 1 . 1' respectively. In general, preferably by means of a device according to the invention a force profile over the entire width of the roll or roll 1 . 1' be determined. In addition, it is possible in particular an optical waveguide 4 . 4 ' to provide for measuring the temperature and another optical fiber 4 . 4 ' to provide for the measurement of strains or forces.
  • 3 shows a schematic example of a drive roller 1'' as indicated by the arrows in the center of the roll 1' is flowed through with cooling medium. In essence, they are parallel to the surface of the main body 2 '' the role 1'' optical fiber 4 '' in holes 3 '' in the main body 2 '' brought in. The optical fibers 4 '' in the main body 2 '' can, as in 3 represented by a fiber optic rotary transformer 5 with fixed optical fibers 4 '' outside the main body 2 '' the role 1'' get connected.
  • The optical fibers 4 . 4 ' . 4 '' Finally, according to the invention are connected to an evaluation system, wherein laser light in the optical waveguide 4 . 4 ' . 4 '' Gelei tet and using a suitable evaluation the temperature and / or the force along the respective optical fiber 4 . 4 ' . 4 '' can be determined. A candidate evaluation method for the fiber optic temperature measurement method is, for example, the known fiber Bragg grating (FBG) method. In this process, optical fibers 4 . 4 ' . 4 '' used, the measuring points with a periodic variation of the refractive index, or grating with such variations, get impressed. This periodic variation of the refractive index leads to an optical waveguide 4 . 4 ' . 4 '' represents a dielectric mirror as a function of the periodicity for specific wavelengths at the measuring points. By a temperature or pressure or a force change at one point, the Bragg wavelength is changed, and this is reflected exactly. Light that does not satisfy the Bragg condition is not significantly affected by the Bragg grating. The different signals of the different measuring points can then be distinguished from one another on the basis of propagation time differences. The detailed structure of such fiber Bragg gratings, as well as the corresponding evaluation units, is well known. The accuracy of the spatial resolution is given by the distance of the impressed measuring points.
  • Alternatively, for the temperature measurement, the Optical Frequency Domain Reflectometry method (OFDR method) or the Optical Time Domain Reflectometry method (OTDR method) can be used. Both methods are based on the principle of fiber optic Raman backscatter, taking advantage of a temperature change at one point of an optical fiber 4 . 4 ' . 4 '' causes a change in the Raman backscatter of the optical waveguide material. Using the evaluation unit, for example, a Raman reflectometer, then the temperature values along a fiber 4 . 4 ' . 4 '' be determined in a spatially resolved, wherein in this method over a certain length of the conductor 4 . 4 ' . 4 '' is averaged. In this method, a measuring point thus extends over a certain length of the fiber 4 . 4 ' . 4 '' , which is currently a few centimeters. The different measuring points are separated by transit time differences of the light. The structure of the systems for evaluation according to the said methods is well known, as are the necessary lasers, the laser light within the fiber 4 . 4 ' . 4 '' produce.
  • For force or pressure measurement, the above-described and known fiber Bragg grating method can also be used. Because the effect of a pressure or a force on the optical fiber 4 . 4 ' . 4 '' , also changes the lattice constant of the material and thus also leads to a change in the Bragg wavelength. It is also possible to determine the forces on the roller or roller surface by the likewise known Brillouin method. Brillouin sensors are based on the Bragg reflection of laser light on acoustic gratings induced by electron oscillations within a silicon molecule. In combination with an optical backscatter method, the fiber deformation can be continuous along the fiber or optical fiber 4 . 4 ' . 4 '' be determined. Another method of measuring the forces on the roller surface uses so-called micro-gend-sensing which are based on the optical micro-gending effect and a fiber curvature of the optical waveguide 4 . 4 ' . 4 '' or a bend with a light emission react. These radiation losses can be measured in a spatially resolved manner with the aid of a backscatter reflectometer. This method of measuring forces or strains is also known per se.
  • As already briefly related to 3 described, the optical fibers can 4 . 4 ' . 4 '' through a fiber optic rotary transformer 5 (rotating laser coupling or "fiber optical rotary joint") with the evaluation system, which is outside the roller or roller 1 . 1' . 1'' is to be connected. For the sake of better understanding, it is in 4 schematically an example of a fiber optic rotary transformer 5 shown. By the reference numeral 4 '' In this case, an optical waveguide is shown, which is located within the main body 2 . 2 ' . 2 '' the roller or roller 1 . 1' . 1'' located. The area 6 (Rotor) is with the main body 2 . 2 ' . 2 '' connected, so that this with the roller or roller 1 . 1' . 1'' rotates. The area 7 (Stator) is fixedly mounted in the system frame. At the opening 4 '' occurs in the plant frame stationary optical fiber out (not shown). Such fiber optic rotary transformer 5 are well known. In order to improve the robustness of the signal transmission, it is further possible to guide light waves via likewise known lens connectors from a roll stand to the evaluation unit.
  • The device according to the invention can serve in particular for the mechanical and thermal loading of the rollers or rollers 1 . 1' . 1'' to monitor. In addition, it can be concluded from the values determined preferably on the load of a strand or band. For example, the strand surface temperature can thus be determined permanently and precisely. In addition, for example, known models for heat transfer between a roller 1 . 1' . 1'' and a strand are applied. Thus, a permanent determination of the strand surface temperature can take place. A determined strand surface temperature can subsequently be used for measurement and control tasks.
  • In general, the inventive arrangement for many types of rollers or rollers 1 . 1' . 1'' Some are: guide rollers, rolling rolls, drive rollers, drive rollers and many more. These can be used in particular, but not exclusively, in casters, rolling mills or in other strip processing lines.
  • The Measurement of the forces on rollers by means of the optical fiber takes place by a measurement of the elongation of the optical waveguide due the force effect. For the force measurement, it is important that the optical fiber has a direct immediate contact with the material of the roll / roll, in particular with the roll shell Has; The optical fiber then acts as a kind of strain gauges. That is an elongation or bending of the bearing due forces then immediately cause an expansion or compression of the fiber optic cable firmly connected to the roller. For detecting the elongation of the optical waveguide, it is preferable required that on the optical waveguide a so-called Bragg grating is applied. A laser beam fed into the optical waveguide is generated at the Bragg grating each have a different diffraction pattern the light fed in according to the strain.
  • The Elongation of the optical waveguide can basically both by a force on the roller / roller as well as by a Temperature change in the roller and thus in the optical waveguide be caused. In order to measure the force of a possibly temperature change to the elongation of the optical waveguide being able to exclude in the roll, it is advantageous when the roller is at a constant force during the force measurement Temperature is maintained.
  • Also the measurement of temperature is based with the help of fiber optics on a measurement of the elongation or compression of the optical waveguide. When measuring the temperature with the aid of the optical waveguide the elongation of the optical fiber due to a change the ambient temperature of the optical waveguide observed. Also Here, the observation of the elongation is preferably done with the help a Bragg grating, which is arranged on the optical waveguide is. To help with the temperature measurement, the underlying lying stretching of the optical waveguide not by a force on the roller / roller is caused, it is important that for the temperature measurement used fiber optics, d. H. loose in holes or sleeves in the roll or the Walzmantel are arranged. That is, unlike the The optical fibers have force measurement during the temperature measurement no direct contact with the roll material and are the mechanical loads the roller is not exposed.
