Definitions

  • the invention relates to a method for producing a coil of metal strip, the strip being rolled out of a slab in a rolling train by means of a number of roll stands and then wound up on a coiler to form a coil.
  • strip is rolled in a rolling mill and then wound into a coil.
  • the coil is delivered to its place of use and then recycled as intended. This means in particular that products corresponding to the defined specification are manufactured from the band.
  • the invention is based on the object of developing a method of the type mentioned at the outset in such a way that it is possible to provide coils of wound metallic strip that meet specific requirements.
  • the coil should have different strip sections that differ in their properties and thus allow the user of the coil to optimally use a coil.
  • it should also be possible to produce strip from pre-strips or thin slabs with different steel grades and/or with different thicknesses and widths and to provide them in a coil.
  • the solution to this problem by the invention is characterized in that the slab to be rolled is composed of at least two partial slabs which are connected to one another before rolling in the rolling train are connected, the finished coil having at least two strip sections that were made from the at least two partial slabs.
  • slab This term is to be understood here in general terms.
  • slab is usually used for the material in front of the roughing stand, after which it is roughing strip. Belts are then spoken of in and after the finishing mill. Strips are made from thin slabs in a CSP plant. In the present case, the material before the finishing train is primarily meant. However, slabs in the actual sense can also be treated according to the invention.
  • connection of the at least two partial slabs upstream of the rolling mill is preferably carried out by means of a slab connection device.
  • the at least two partial slabs are connected in the slab connecting device by friction welding, in particular by linear friction welding.
  • the partial slabs and/or the strip sections rolled from them differ from one another in particular in terms of their material.
  • the band sections can also differ from one another in terms of their geometry, in particular in terms of their width and/or thickness.
  • Rolling in the rolling mill is preferably carried out in a continuous process.
  • the at least two partial slabs can be produced in at least two different casting machines.
  • At least one of the partial slabs can be temporarily stored before being connected to the other partial slab.
  • the intermediate storage of one partial slab preferably takes place at least temporarily in a furnace.
  • the one partial slab can also be temporarily stored in a coil box, at least temporarily.
  • At least one of the partial slabs can be supplied as separately manufactured material from another manufacturing facility. It can also be provided that the material supplied is used as a sample, as a model or as material for calibrating the rolling train or parts thereof. This material or any other part can then be taken for samples or samples or as scrap, in particular as planned in the event of changes in production conditions (so-called transition zones) or as a result of production phases that do not go according to plan.
  • the slab joining device is preferably provided between a tunnel furnace following a caster and the first stand of a finishing train in a cast-rolling plant.
  • the slab joining device can also be provided between the last stand of a roughing train and the first stand of a finishing train in a hot rolling mill.
  • the strip to be finish-rolled can be assembled from several sub-strips, which are provided from a coil box or directly from the roughing mill.
  • this also includes pre-strips that are connected to one another in order to be able to roll them out, in particular in a continuously operating rolling process.
  • the proposed method can be used in conventional hot strip mills or in continuous casting plants (CSP plants).
  • the proposed method thus allows the joining of slabs or pre-strips with different properties.
  • the strips are preferably connected to one another by friction welding, then rolled and finally wound into a coil in such a way that there are different strip sections on it, which are characterized by different properties.
  • the strip wound into a coil has at least two, preferably several sections, which in particular consist of different materials or have different geometric dimensions.
  • the slabs or pre-strips that are joined together can come from different sources and in particular from external production.
  • the point of separation before coiling is defined at a desired location that is independent of the point at which the slabs or pre-strips were connected to one another.
  • the coil 1 is wound in such a way that it consequently has at least two strip sections 6a and 6b, which differ from one another in terms of their properties.
  • the two band sections 6a, 6b are in figure 2 marked with different hatching.
  • the buyer of the coil 1 thus has the possibility of supplying a single coil to different uses, in which the respective strip sections are recycled or used differently.
