Definitions
- the invention relates to a method for stabilizing the strip of a guided between the wiping nozzles of a hot dip coating plant, provided with a coating tape and a corresponding Schmelztauchbe- coating system.
- a method for stabilizing the strip of a guided between the wiping nozzles of a hot dip coating plant provided with a coating tape and a corresponding Schmelztauchbe- coating system.
- electromagnetically contactless acting on the continuous steel strip coils stabilizing forces in accordance with the detected tape position on the tape.
- Electromagnetic strip stabilizers are based on the principle of induction in order to generate attractive forces perpendicular to the ferromagnetic steel strip by means of defined magnetic fields. Thus, the position of the steel strip between two opposite electromagnetic inductors (electromagnets) can be changed without contact.
- Such systems are known in different types. They are e.g. used in hot dip finishing plants in the coating area above the so-called wiping nozzles.
- Various control and control concepts are known (eg DE 10 2005 060 058 A1, WO 2006/006911 A1).
- Wiping nozzles are used in hot-dip coating plants for steel strip in order to obtain a defined amount of coating medium on the strip surface.
- the quality of the coating depends to a large extent on the uniformity of the wiping medium (eg air or nitrogen) as well as on the band movement in the nozzle area.
- the belt movements are caused by non-circularity of rollers or, for example, by impulse effect of the air in the cooling tower area of hot-dip finishing plants. As the strip movement in the stripper nozzle increases, the coating quality or uniformity of the coating of the continuous steel strip is reduced.
- strip stabilization systems connected downstream in the strip running direction can damp or reduce strip movement occurring within the scraping nozzle, so that an improvement in the coating accuracy and coating uniformity of the liquid metal on the steel strip is achieved.
- This can z. B. be electromagnetically acting actuators exert contactless attractive forces on the convincedlau- fenden steel strip and thus change the band position.
- the goal of all applications is to position the belt stabilization as close as possible to the wiper nozzle, ignoring the relationship between distance and effect.
- the object of the invention is therefore to improve the strip stabilization in the region of the wiper.
- This object is achieved according to the invention with the method according to claim 1.
- This is characterized in that the distance (the effect) of the band stabilization of the wiping nozzles is set to a value equal to a distance threshold value, which as a function of Bandwidth is determined taking into account a factor Phi, wherein the factor Phi is calculated as a function of the strip thickness and the strip tension.
- the measured variable strip position represents the temporal and / or local change in the distance of the strip relative to a straight reference line transversely to the strip running direction; that is, the tape position represents the tape profile and / or its vibration behavior as a function of time.
- strip stabilization encompasses two essential aspects: on the one hand strip stabilization means smoothing of a wave-shaped strip profile and on the other hand this term means damping of vibrations of the strip. Both aspects of band stabilization can be implemented independently or in combination or simultaneously with the aid of suitable control circuits.
- the essential advantage of the claimed limitation of the distance is that if the distance is set to a value below the distance threshold value which can be calculated according to the invention, a considerably better effect is achieved for both aspects of the desired band stabilization. In contrast, the effect of band stabilization at intervals above the distance threshold decreases significantly or the band is despite stabilization even more unstable than without control (opposite effect).
- Ideal would be a distance of zero, that is, if the band stabilization at the level of the scrapers would be arranged, because then the band stabilization would act directly at the level of the stripping and the tape would then held optimally stable during a measurement process.
- this arrangement is structurally not feasible due to lack of space in the rule. Therefore, the distance should be as small as possible, but maximally set to the value of the distance threshold value which can be calculated according to the invention.
- the electromagnetic forces are applied by on each band side in pairs opposing coil assemblies whose distance from the wiping nozzles is changeable.
- the band position within the coil arrangement is preferably measured, specifically in the spatial vicinity of the coil arrangement.
- the tape position above and below the coil assembly can be measured.
- a plurality of coils are arranged on each band side, wherein the respective outer coils are arranged to be adjustable on the continuous band edges parallel to the plane of the band.
- the distance of the belt stabilization device, hereinafter also abbreviated to belt stabilization, of the wiping nozzles should not exceed their bandwidth for wider belts (B> 1400 mm). For narrower bands (B ⁇ 1400 mm), a spacing of up to 1.75 times the bandwidth can be allowed. This distance results from the principle of Staint-Venant, which states that with increasing distance of an attacking force on z. B. a clamped steel strip whose effect on the overall state decreases.
- the basis for the solution according to the invention is the positioning of the strip stabilizer to the wiping nozzle or the wiping nozzles, taking into account the stress mechanism.
- the distance between the stabilizing effect and the scraper in a specified range or . may not exceed a maximum in the form of a distance threshold.
- the above object is further achieved by the claimed melt-dipping coating system.
- This is characterized in that the distance (effect) of the strip stabilization from the wiping nozzles is set to a value less than or equal to a distance threshold determined as a function of the bandwidth taking into account a factor Phi as a function of strip thickness and strip tension.
- the distance threshold value is based on the principle of Venant for continuous wide steel bands at approx. The bandwidth and for narrower bands max. 1.75 times the bandwidth (see FIG. 5). At a greater distance, the effect of band stabilization in terms of smoothing the band profile (transverse arc, S-shape, see Fig. 2) is very limited or no longer recognizable at long distances.
- the following device for combining the strip stabilization with the wiping nozzle, in which the strip stabilizing coils always act towards the centered strip layer:
- the stabilization must be respectively aligned to the band position and the actual position must be determined.
- the alignment is carried out by means of specially mounted alignment aids.
- the stabilization is mounted on this frame and is therefore mechanically fixed and reproducibly adjustable (FIG. 3).
- the centering on the band position or band center is therefore always identical between stabilization and the scraper nozzle.
- Wiping nozzles and stabilizing coils are mechanically synchronized and aligned!
