Definitions

  • the invention relates to a method for producing a metallic strip, the strip being rolled in a rolling mill, the strip being subjected to a bending stretch straightening process in a bending straightener at a point downstream of the rolling mill, and the strip being subjected to a point downstream of the bending stretcher in the conveying direction on a reel. Furthermore, the invention relates to a plant for producing a metallic strip.
  • stretch straightening machines that can be used behind hot strip mills have been proposed to improve flatness.
  • Such an application for continuous rolling is for example in the GB 2 163 689 A disclosed.
  • An arrangement of stretch leveling machines in front of a reel driver or between the reel driver and reel is disclosed by the DE 2 537 188 A1 , the US 4,316,376 A , the EP 0 906 797 B1 , the DE 199 53 915 A1 , the EP 2 038 076 B1 and the EP 3 061 535 A1 .
  • a stretching judge is located directly behind the hot strip mill in the US 4,539,830 A and inside the cooling section in the DE 10 2013 214 344 A1 disclosed. Show more solutions DE 10 2005 060 046 B4 and the EP 1 230 993 B1 .
  • the object of the invention is therefore to provide a method and a system with which it is possible to increase the degree of flatness of the strip.
  • the solution to this problem by the invention is characterized in that the strip between the rolling mill and the bending straightener is kept at least temporarily under a first tension, that the strip is kept behind the bending stretcher at least temporarily under a second tension in the conveying direction, and that the strip in The area of the bending straightener is kept at least temporarily under a third tension, the third tension being greater than the first tension and the second tension.
  • the first tensile stress and the second tensile stress are preferably between 5 and 25 N / mm 2 .
  • the third tensile stress is preferably between 30 and 80 N / mm 2 , particularly preferably between 40 and 60 N / mm 2 .
  • the head and the end of the band are exempt from said tension.
  • the train level on the transport route before the bending straightener route and the transport route after the bending straightener route can be different.
  • the average tension level within the stretch straightening section is preferably determined as a function of the strip material, the strip temperature within the straightening section and the strip thickness and is preferably set and controlled using a process model.
  • a train model also defines the train level in the neighboring transport routes.
  • the train level on the long transport route between the last active roll stand and the first driver of the bending stretcher and the transport route from the second driver of the bending stretcher and the reel driver or the reel is thus lower than the train level within the Bending straightener line. Accordingly, the trains in the area of the bending straightener line are decoupled from the neighboring lines.
  • the tension in the belt is preferably influenced, controlled or regulated by a first driver and a second driver, the first driver being arranged in front of the bending straightener in the conveying direction and the second driver being arranged behind the bending straightener in the conveying direction, or the two drivers extending the bending straightener in the conveying direction limit (in the latter case, the two drivers are therefore part of the bending straightener).
  • the different train levels are set by the drivers in front of and behind the bending straightener.
  • a scissor driver or a reel driver can also take over their task. In this case, the increased third tensile stress is built up in the area of the bending straightener between the first driver and a reel driver.
  • the distance a then applies between the first driver and the reel driver.
  • the second driver is then open or not installed.
  • the second tension then only applies between the reel driver and the reel.
  • At least one further driver e.g. a scissor driver
  • the strip is preferably subjected to cooling in a cooling section between the rolling mill and the bending straightener. Cooling in the conveying direction behind the bending straightener preferably no longer takes place.
  • the advantage of this type of cooling of the strip is that the cooling section no longer influences the flatness of the strip in this way.
  • the strip preferably has a temperature in its bending stretching process which is between 20 ° C. and 750 ° C., particularly preferably between 200 ° C. and 600 ° C.
  • a hot strip which has a thickness between 0.5 mm and 2.5 mm is particularly advantageously produced using the method mentioned.
  • the plant for producing a metallic strip comprises a rolling mill for rolling the strip, a bending straightener downstream of the rolling mill in the conveying direction of the strip and at least one reel downstream of the bending straightener and provides according to the invention that the bending straightener has a first driver arranged at the front in the conveying direction and one has second drivers arranged in the rear in the conveying direction, the two drivers limiting the extent of the bending straightener and the distance in the conveying direction between the first driver and the second driver being at most 20 m.
  • the distance is preferably at most 5 m. This minimizes the throughput time through the bending straightener and the associated constriction of the belt as a result of the train.
  • a cooling section is preferably arranged between the rolling mill and the bending straightener; behind the bending straightener there is preferably no cooling section.
  • the bending straightener has a number of rollers for introducing a bending moment into the strip, the diameter of the rollers preferably being at least 50 mm, particularly preferably at least 100 mm.
  • the bending straightener section includes a bending straightener consisting of a number of rolls (for example 5 rolls) and / or a back bending unit consisting of further rolls (for example 3 rolls).
  • the driver can consist of two rollers standing one on top of the other or can be designed with an offset arrangement of the rollers in order to generate a wrap angle and, if appropriate, additional torque transmission.
  • the stretching judge rollers preferably have internal cooling and / or they are equipped with stripper plates for external cooling to shield the water from the strip so that the Reel temperature is not adversely affected.
  • the strip cooling in the bending stretching section is also taken into account and is taken into account when determining the target strip temperature behind the cooling section, so that the desired reel temperature is generated.
  • the invention thus relates in particular to a hot bending straightener behind a hot strip mill.
  • the proposed solution thus provides an optimization of the bending straightener arrangement and the tension distribution, which subsequently leads to an improved flatness of the strip produced.
  • a good flatness improvement by means of a bending stretch straightening process results for a given strip material with high strip tension, high strip temperature and small bending radii of the strip, i. H. with small straightening roller diameters.
  • straightening roller diameters that are too small are disadvantageous with regard to maintenance, service life and roller wear.
  • Too high trains and / or too high strip temperatures result in large constrictions in width on the long route between the last rolling stand of the hot strip mill and the reel.
  • the narrowing of the width due to tape tension is also dependent on the flatness condition itself and is therefore difficult to determine.
  • the cooling section also influences the flatness of the belt.
  • FIG. 1 A system for producing a steel strip 1 is shown, with only the last rolling stand being indicated by a rolling mill 2, from which the strip 1 runs in the direction of conveyance F in the direction of a reel 4 (two reels 4 are provided here by way of example). Between the rolling mill 2 and the reel 4, a bending straightener 3 is arranged, in which the strip is straightened by a bending stretching process.
  • the bending straightener 3 is limited in its extension in the conveying direction F by a first driver 5 and a second driver 6, a distance a being present between the two drivers 5, 6.
  • the bending straightener 3 has a number of rollers 8, which are designed to apply corresponding bending stress to the belt 1 in a manner known per se.
  • a cooling section 7 is provided, which is arranged between the rolling mill 2 and the bending straightener 3 and with which the strip 1 can be cooled.
  • Figure 1 indicated some components that are relevant for the implementation of the production process of the strip 1, namely a flatness measuring device 9, a temperature measuring device 10, a temperature measuring device 11, a pair of scissors 12 and a reel temperature measuring device 13.
  • the conveyance of the strip 1 between the rolling mill 2 and the reel 4 results from the interaction of the last rolling stand of the rolling mill, the first and the second driver 5, 6 and in the exemplary embodiment by a reel driver 14.
  • a reel driver 14 By appropriate regulation of the components mentioned and in particular the first and second drivers 5, 6, the tension in the band can be influenced.
  • a first tensile stress ⁇ 1 is initially present between the rolling mill 2 and the bending straightener 3, which is preferably in a range between 5 and 25 N / mm 2 .
  • ⁇ 2 there is a second tensile stress ⁇ 2 between the bending funnel 3 and the reel 4, which is also preferably in a range between 5 and 25 N / mm 2 .
  • the two tensile stresses ⁇ 1 and ⁇ 2 need not be the same.
  • the third tensile stress ⁇ 3 is in a preferred range between 40 and 60 N / mm 2 .
  • the distance a is relatively short and preferably only extends over approximately 5 m.
  • the throughput time through the bending straightener 3 is short, which also results in only a small constriction of the band as a result of the train.
  • the shears 12 are used in continuous rolling.
  • the driver 6 takes over the tension component ⁇ 2 in order to be able to maintain the tension ⁇ 3 in the area of the bending straightener.
  • the bending stretch straightening process is thereby significantly improved. This applies in particular if the process is operated with further parameters, as explained above.
  • the temperature control which is preferably chosen so that the strip 1 in the area of the bending funnel 3 has a temperature between 200 ° C. and 600 ° C.
