Definitions
- the invention relates to a method and a device for straightening cold rolled strip, the strip passing through a brake roller set and a pull roller set and being subjected to a stretching train between the two roller sets in the course of its stretching, and a regulation of the degree of stretching.
- EP 0 393 301 B2 discloses a process for the continuous tensile stretching of metallic strips with a strip thickness between 0.05 mm and 0.5 mm, in particular strips made of steel, aluminum or similar metals. There, the strip to be straightened passes through a brake roller set and a pull roller set and is stretched between the two roller sets in the course of its stretching in the plastic region, which corresponds to the stretch limit of the strip material or slightly exceeds this stretch limit.
- this straightening system has a pair of stretching rollers between the brake and the pulling roller set, so that the strip is superimposed with an additional stretch, which causes stretching in the plastic area. While the rollers of the brake and pulling roller sets have a relatively high stretching draw share, only about 5 to 25% of the stretching pull is generated with the pulling stretching roller pair.
- the invention has for its object to provide a generic method and an apparatus for performing the method and also a regulation of the degree of stretching, with which the to be straightened, annealed, pickled and optionally trained cold strips with improved high quality, especially high surface quality, elastic and plastic stretch.
- This object is achieved with a method according to the invention in that the belt is subjected to bending under tension in a high-tension roller set arranged between the brake roller set and the pull-roller set in order to increase the degree of stretch.
- a preferred measure provides for the strip to be subjected to an alternate bend in the hoist roller set. This realizes the realization that when the strip is bent with a superimposed tension, the resulting degree of stretching increases and strip thicknesses of the strips, primarily made of stainless steel, but also strips made of such materials, which are characterized by a high surface quality, are greater than 0 , 5 mm with an increase in the achievable flatness and reduction in the residual stress conditions. Along with this, the surface fineness and surface gloss of the stretch-oriented metal strip is improved.
- the mode of operation with alternate bending in the hoist roller set which according to the invention generates the main part of the stretch train while the remaining stretch degree is distributed over the brake and pull roller set, helps to further increase the degree of stretch.
- the band is plastically extended by superimposing the band tension and bending at the point of run-up or run-off of the band onto the individual rolls of the hoist roll set.
- a point-symmetrical structure of the bends in the pull-up part can be achieved, in particular in the case of thicker strips which cannot be stretched between the rollers simply by pulling.
- the strip is guided through the pull-up roller set with a short tensioning length between the respective unwinding and run-up points of the individual rollers.
- This short tensioning length which is understood to mean the free, unguided length of the belt between two successive rolls in the belt run, means that the belt run is improves and reduces the tendency of the tape to form longitudinal folds.
- the short guy length can be achieved, for example, by the fact that the rollers of the hoist roller set, which follow one another in the direction of the looping or the belt passage, are at a smaller distance from one another than is the case with conventional S-roller arrangements.
- the hoist roller set provided between the brake and the pull roller set has at least two, according to a preferred embodiment, four pull rollers arranged to produce tape tension and bending.
- these S-shaped integrated rollers in the hoist roller set no longer require bending cassettes and adjustment systems.
- they produce the high degree of stretching desired by superimposing the bending and tensioning of the strip, a four-pulley hoisting roller set also providing alternate bending and a further increased degree of stretching in the hoisting area.
- An embodiment of the invention provides that the pull rollers of the pull-up roller set have a different diameter than the rollers of the brake and pull roller sets.
- the plasticization of the strip and thus the achievable or adjustable degree of stretch can be influenced on the basis of a specifically set speed difference.
- a hoist roller set with four rollers either only the inner two pull rollers or all four rollers can be provided with roller diameters that differ from the remaining rollers, ie those of the brake and pull roller set. If these pull-up rollers have a smaller diameter than the other rollers, the smaller the diameter, the greater the degree of stretching that results when the strip is bent with a superimposed tension. The limits are where the belt surfaces could be damaged.
- Figure 1 in a very schematic side view of an embodiment of a stretch leveling system with an intermediate hoist part
- Figure 2 shows a control scheme for controlling the degree of stretch with distribution of the individual degrees of stretch.
- a system 1 for straightening stainless steel strips 2, preferably with thicknesses above 0.5 mm, as shown in FIG. 1, consists of a brake roller set 3 and, viewed in the direction of the strip passage indicated by arrows, then a brake roller set 5 and a pull roller set 4
- the brake roller set 3 is designed with four rollers 6 and the pull roller set 4 with four rollers 7, which are each arranged in pairs in an S-shape.
- the hoist roller set 4 also has four rollers, which are also in pairs S-shaped are arranged, namely the inner pull rollers 8a and 9a and the complementary rollers 8b and 9b.
- the upper pair of rollers 8a, 8b and the lower pair of rollers 9a, 9b are arranged on the one hand with respect to the individual rollers and on the other hand from one pair of rollers to the smallest possible distance.
- a short guy length 10 is thereby achieved, which is defined in each case between the run-off point 11 of the preceding roll in the strip running direction and the roll following in the strip running direction, as a result of which the strip running is improved and the formation of longitudinal folds (towel effect) is reduced. Since the band 2 in the pull-up roller set 5 is subjected to an alternate bend - with only one existing pair of rollers in any case a bend - in the pull-up roller set 5 there is an increased degree of stretching due to the bending of the band under tension.
- the degree of stretch resulting from the bending of the strip 2 with a superimposed tension becomes greater the smaller the diameter of the rolls.
- the limits are where a small roll diameter has an adverse effect on sensitive belt surfaces, because a rather large roll diameter, e.g. 800 to 1500 mm, reduces the influence.
- the roll diameters are selected, there is definitely a plastic extension of the strip 1 by superimposing the strip tension and bending in the run-up or discharge point 11, 12 of the rolls 8a, 8b or 9a, 9b.
- a hoist roller set 5 is arranged between the brake roller set 30 and the pull roller set 40.
- the braking and pulling roller set 30 or 40 here, however, consists only of a pair of rollers formed by the rollers 6 or 7, but the roller arrangement of the pulling-up roller set 5 in turn on the one hand for a short guy length 10 and on the other hand by bending superimposed train resulting in high degree of stretching.
- the control scheme shown allows the degree of stretching to add up to a total degree of stretching due to the mutual influence of the individual degrees of stretching in the up and down points 12 and 11 of the rollers in the hoist roller set 5.
- a suitable degree of stretch is achieved with a suitable precontrol and regulation of the individual torques.
- the degrees of stretch are tapped outside of the hoist roller set 5 between the train-building and straightening rollers or the straightening and train-dismantling roles of the brake and the train roller set 30 and 40 and attributed to the torques of the rollers of the hoist roller set 5. This makes a meaningful distribution of the individual degrees of stretch possible.
