Definitions

  • the invention relates to a method for applying a controllable tensile stress distribution, especially in the edge regions during cold rolling of metal strips, in order to reduce the risk of too high tensile structure and band edge cracks with the adverse consequence of production-reducing band breaks, and to improve the strip surface and its flatness even at relatively higher Tape speed and to reduce Bandbeklan, according to the preamble of claim 1 (see, eg JP-A-62142011 ).
  • the invention also relates to an apparatus for carrying out the method, according to the preamble of claim 5.
  • Process is collected before the nip and separated again. This makes it possible to produce the emulsion or dispersion, which is introduced into the nip, time and again with a certain concentration before moving into the nip.
  • the focus of this invention is the actual production of the emulsion and the separation of the involved media.
  • the document EP 1 188 494 A1 describes a belt scraper, belt scraper method, rolling mill and rolling method. To improve the productivity of a cold rolling device, this was provided with a belt scraper.
  • the document EP 0 672 471 B1 discloses a method and apparatus for rolling ribbons.
  • rollers wear-resistant at least in one of its end regions with enlarged radii running rollers are shifted from each other so that the rolled strip in its width in each case with areas of smaller radius in contact, and that with increasing heating and with thermal crowning by opposing displacement of the rollers Regions of their larger radius are pushed over edge regions of the rolled strip.
  • edge area elevations of the strip which would occur due to the rising thermal crowning, are eliminated.

  • drying and keeping dry particular of rolled strips it is known by a partitioning the dry area of the finished rolled strip from the wet room of Separate rolling stand.
  • a non-contact seal between the foreclosure and the tape by an air cushion-like compressed gas cushion and a slit flow is proposed so as to apply compressed gas from a plurality of nozzles from Blasdüsenangn at right angles from above and below the tape surfaces. This measure prevents penetration of rolling oil or even emulsion at high belt speeds of over 1000 m / min, irrespective of the bandwidth, and achieves non-contact belt drying.
  • the document DE 101 31 369 A1 discloses a method and apparatus for cooling and / or lubricating rolls, in particular the work rolls of a rolling stand and a rolled strip conveyed between and conveyed through these rolls, using water in the form of sprays as cooling medium and spray oil, oil-air mixture or oil -Water mixture, as a lubricant.
  • a combined use of supercooling of the belt and roll surface and the roll lubrication on the scaffold inlet side is proposed by the two media - water or lubricant - the rolls or the strip fed separately and to different application sites of the rolling surface be applied.
  • the European patent EP 0 672 471 B1 discloses a method and apparatus for rolling belts with axially displaceable rollers.
  • the method is characterized in that low-wear, executed with at least at one of its end portions with enlarged radii rollers are shifted against each other such that the rolled strip is in its width in each case with areas of smaller radius in contact and that with increasing heating and with thermal crowning By oppositely moving the rollers and areas of the rollers with a larger radius are pushed over edge regions of the rolled strip.
  • This method is used to counteract the annoying, thermal crowning effect simply and inexpensively, in order to make rolling plans more free.
  • the U.S. Patent 5,943,896 discloses a method for influencing the contour of a rolled strip in the edge region.
  • each work roll has a smaller diameter portion at one end than at the other end thereof, the smaller end portion being shorter than the large diameter portion across the width of the work roll.
  • the diameter of the work roll linearly changes from the small diameter to the larger diameter.
  • the two superposed rollers are arranged so that the thinner end of the one roller is opposite to the thicker end of the other roller.
  • the Japanese godparent application JP 05050122 discloses an apparatus and method for realizing a sharply separated heat transfer between different temperature ranges on the surface of a work roll.
  • the Japanese application 03297507 discloses a method for detecting the occurrence of stresses in the edge regions of a rolled strip and an extension to prevent the edge areas. For this purpose, it is proposed to apply a cold coolant in the region of the center of the rolled strip, that is to say not in its edge regions, and at the same time to apply a warm coolant in the edge regions and outside thereof.
  • German patent application DE 31 144 87 A1 discloses a method and apparatus for roll tempering in cold rolling mills.
  • a roll area which lies outside the strip edge and adjoins directly to the strip edge be tempered by applying heated lubricant.
  • a relatively sharp borderline between hot and cold lubricant jet is set. The position of this boundary line should coincide with the position of the band edge.
  • the invention is in the cold rolling, especially in the aluminum industry, but occasionally in the steel and non-ferrous metal area, the task of further reducing the resulting during thin rolling strip edges and near-edge long strip fibers and tape cracks on To further save edgebandings and thereby further improve the quality and quantity of application.
  • This object is achieved by the method claimed in claim 1.
  • This method is characterized in that the strip edges are influenced by "hot edge spray", in particular by zonewise spraying of rolling oil at different temperatures, and in the Work rolls in the Beriech the band edges a special finish is used, which is suitable for partial buildup of material in the prestretch, the material structure in subsequent stitches leads to a longer band edge and counteracts the risk of high Gebupes.
  • An embodiment of the method according to claim 1 provides that an increased diameter decrease of the work rolls is made at the edge region due to partial increase in diameter during their shaping by means of inductive heating.
  • the strip tension distribution is changed by a concave bendable or curved guide roller such that the tape tension is reduced at the strip edges and increased in the center of the strip.
  • Another embodiment of the device advantageously includes a convexly bendable in the belt running direction or curved steering roller in an arrangement between two guide rollers for changing the tensile stress distribution of a strip before its entry into a rolling stand.
  • the device is further configured by the fact that they are on the inlet side of a rolling mill means for direct additive application, in particular on the rolled strip z. B. for lubricating oil with relatively high viscosity, and on the outlet side of the work rolls means for bale cooling of the work rolls and preferably additional lubricant removal means which spray the rolled strip with preference from both the tape top and from the underside of the band with the attributable spray media.
  • the device according to the invention has a device which removes coolant in the outlet side of the scaffold.
  • FIG. 1 shows a part of a device for applying a controllable tensile stress distribution, in particular in edge regions during cold rolling of metal strips, with in at least two separate zones 10, 10 'existing spray nozzle assemblies 11, 11' with connections to separate Sprühstoffzu exiten 19, 19 'to different zones 10, 10th
