Definitions
- the invention relates to a method for continuous Straightening thin metal strips, in particular Aluminum and stainless steel strips with strip thicknesses of 0.1 mm up to 0.5 mm, in a belt process line, after which belt unevenness and / or the strip profile measured before straightening and then depending on the measured values determined at least one directional parameter is regulated in advance.
- the invention is based on the technical problem Processes of the type described at the beginning so on form that the metal strips flawlessly and continuously be addressed, taking into account limited Values for the target parameters.
- the invention proposes to solve this technical problem in a generic method before that as Guideline parameters of the strip tension taking into account stored Guide values for different metal strips immediately before winding the metal strip in question continuously pre-regulated via the rewinder becomes.
- the invention is based on the knowledge that the judging result essentially of influencing factors, such as the Strip flatness and the strip profile, depending on the leveling is. If these influencing factors are determined, the Straightening process by varying the strip tension immediately before optimized the winding of the metal strip in question become. In this context it is also important that usually the degree of stretch can be minimized to the Material properties of the metal strip in question to influence as little as possible and still the same Get judge result. Unplannedness is always in the Infeed area of the metal strip in question by measurement detected, so that then the directional parameter or parameters in the way a forward control continuously and optimally set can be.
- influencing factors such as the Strip flatness and the strip profile, depending on the leveling is.
- the optimal guideline values once in a test field with subsequent off-line flatness measurement and then save.
- aluminum coils used in the Rule on the outside diameter of the center bowls and on the inside diameter Have edge waves over the entire Coil length can be optimally directed.
- the second influencing variable, the band profile can be carried out online a traversing thickness gauge can be measured.
- the Setting values of the corresponding straightening system can thus can also be optimized, but the influence of Belt profile during the straightening process not as large as that of band unevenness. But for that it is important that Adjust the tape tension on the rewinder depending on the tape profile. For example, a band profile with a large one Excessive thickness in the area of the strip center after straightening in the wound coil due to and from compressive stresses resulting crawls to center bowls. consequently the flatness is negatively influenced after straightening and is often lost.
- the deflection of the stretch bending rollers may be realized in this way be like this basically in the German patent 33 23 623 is described. This is done in particular with Look at the figures 13 and 14 there a deflection with the help of hydraulic cylinders or by split Pinch rollers as pressure elements.
- the measuring device for the distance measurement can be designed as a shapemeter roll or as a laser beam measuring device with measuring beams arranged perpendicular to the metal strip passing through and across its bandwidth in a predetermined distribution.
- the entire measuring station is preferably in an area of low strip tension and consequently in front of the brake roller set in order to obtain significant measured values.
- Low strip tension means a range of ⁇ 15 N / mm 2 for aluminum strips and ⁇ 50 N / mm 2 for stainless steel strips.
- the traversing strip thickness measuring device is connected to the control device, which regulates the unwinder in advance in order to achieve optimum strip tension.
- the straightening system shown is used for straightening thin ones Metal strips 1, in particular aluminum strips and Stainless steel strips with strip thicknesses from 0.1 mm to 0.5 mm.
- This straightening system has a pull roller set 2 and one Brake roller set 3 on.
- the brake roller set 3 is a measuring station 4 with at least one measuring device 5 for distance measurement perpendicular to the relevant metal strip 1 and above the bandwidth precedes.
- Between the brake roller set 3 and the tension roller set 2 is a stretch roller set 6 with a brake roller 7 and a tension or correction roller 8 with concave and convex adjustable crown.
- Behind the stretching roller set can are still a regulated tension measuring roller 10, which one Stretch bending device 11 follows.
- the stretch bending device 11 has stretch bending rollers 12.
- To the Pull roller set 2 is followed by a rewinder 13.
- To the Measuring device 5 is a control device 14 for at least the Stretching roller set 6, which is adjustable in terms of crowning Tension or correction roller 8, the tension measuring roller 10 and the stretch bending rollers 12 connected.
- band unevenness can be continuously measure and the measurement results in real time to the Pass on control device 14 so that by way of a Advance regulation always an optimal setting of the Straightening parameters and consequently the straightening units is guaranteed so that a continuous Tape error correction is achieved online. Furthermore, an optimal adjustment of the tape tension before Rewinder 13 reach, namely when the measuring station 4 a Belt thickness measuring device traversing the bandwidth has and directly over the rewinder 13 of the tape tension is regulated ahead of the rewinder.
