Definitions

  • the invention relates to a system and a method for the aftertreatment of a metal strip or sheet, in particular of steel with at least two treatment units.
  • Hot-rolled strip after hot rolling to a post-treatment by cold rolling and surface coating.
  • Cold rolling serves to smooth the surface of the hot-worked strip, to achieve high dimensional accuracy, to achieve higher strength through work hardening or smaller dimensions.
  • the application of a protective layer serves to protect the metal strip surface against corrosion. Before such protective layers can be applied to the strip surface, for example by hot-dip galvanizing, the surface must be prepared accordingly, which in particular includes the removal of scale or oxide layers.
  • a well-known cleaning method is pickling, in which the metal strip is cleaned by means of acids.
  • the invention has for its object to provide a plant for the treatment of a metal strip and a method which do not have this disadvantage, i. provide greater flexibility for the plant operator.
  • the individual treatment units can be operated both independently and in a coupled manner in accordance with the system or the system layout.
  • the Treatment units are flexibly interconnected via coupling units, allowing both tape flow through a separate tape handling unit and continuous tape flow through a selected group of processing units and thus a predetermined treatment step sequence.
  • the treatment units are arranged parallel to each other and are connected to coupling units having means for conveying the band from a treatment unit to a parallel adjacent treatment unit so as to form a meandering band flow within the unit.
  • Meandering in this context means moving in a serpentine shape or passing through a series of turns, which do not necessarily have to have the same radius.
  • the coupling units in this case allow a flexible band flow, starting from a first treatment unit in an adjacent treatment unit, which does not necessarily have to be immediately adjacent.
  • the respective treatment unit in which the beginning of the strip is introduced is determined by the plant operator as required.
  • each treatment unit is designed as a completely separate unit, comprising an inlet part, a process part and an outlet part.
  • the treatment units have a first transition between the inlet part and the process part beginning and a second transition between the process part end and the outlet part, wherein the respective coupling units are arranged on at least one of these transitions of each unit.
  • the belt which is to pass successively through different treatment processes is thus conveyed from one process part to the next meandering.
  • each unit can be operated separately or completely independently of the other treatment units or any chain of treatment units can be created by the coupling units. In this way, a plant operator can more easily respond to available material and production peaks.
  • each treatment unit has a basic belt conveying direction, depending on the direction from the inlet to the outlet part.
  • the treatment units are arranged parallel to one another in such a way that the basic belt conveying directions of directly adjacent treatment units run in opposite directions, whereby in each case the process part end of a treatment unit and the process part start of an adjacent treatment unit are connected via a common coupling device.
  • the treatment units are arranged parallel to one another at the same height, that the inlet part of a treatment unit corresponds to the outlet part of a respective other adjacent treatment unit and wherein the tape running direction of the individual treatment units to each other in opposite directions.
  • the units are arranged parallel to each other, that the inlet part of a unit corresponds to the inlet part of a respective other adjacent unit.
  • the tape is - if it is subjected to a treatment chain - promoted by the process part, then back in the opposite direction back to enter via coupling means at the beginning of the process part in the process part of the adjacent unit.
  • the strip may be conveyed along the hall ceiling, when it is no longer to be exposed to the process part.
  • the coupling unit can connect two directly adjacent treatment units or serves to connect two parallel, but not immediately adjacent, units, for example when a relatively seldom-to-travel treatment chain is to be run.
  • the coupling of two treatment systems located farther apart is achieved via a corresponding tape guide or deflection.
  • the system according to the invention is preferably a system for the treatment of a metal strip, starting from rolled stock.
  • the installation comprises at least two treatment units, which are a unit for preparing the strip surface and / or a unit for applying a protective layer to the strip surface and / or a unit for cold rolling.
  • the units are arranged offset from each other in parallel. It is advisable in this case that the units comprise at least one inlet part and a process part and are arranged so that the process part end of a unit is arranged at about the same height with the process part of the adjacent unit to allow a meandering transition.
  • a specific embodiment offers a particular advantage. It is proposed that a unit for preparing the surface and a second unit for applying a protective layer are combined with each other, both having an inlet part, while the unit for preparing the surface has no outlet part. Hot rolled stock can now be cleaned separately in the first unit and then surface coated in the second unit be, with the second unit is optionally equipped by the separate input with cold-rolled strip. The result is a system concept with two separate inlet parts.
  • the advantage of this plant layout is that scaled hot strip is introduced completely separated from a cold strip in the system and thus the Zunderstaub does not affect the treatment of the cold strip.
  • roller combinations are considered which redirect the band according to different techniques.
  • the tape is passed over several rollers arranged one behind the other.
  • the twist method works, in which the band is deflected by running over many roles - in the form of a sling tower. Also possible is the deflection with a driven roller and the twist with a free sling.
  • the coupling units have so-called Twistrollen.
  • Twistrolle is arranged at an angle of 45 ° to the tape running direction.
  • the metal band is guided on a helical track around the Twistrolle and thereby deflected by 90 °.
  • the proposed plant layout relates in its entirety to a treatment plant of rolled metal strip, in particular steel strip.
  • the unit for preparing the strip surface is to be understood as meaning all known means which in some form prepare the strip for cold rolling or coating, either by changing the surface geometry and / or for cleaning and / or activating the metal surface.
  • mechanical devices such as grinding in question, as well as thermal facilities, such as the flame blasting.
  • the preparation is particularly preferably proposed by cleaning on chemical (for example degreasing) or electrochemical routes, for example pickling).
  • the treatment unit for applying a protective layer comprises means for applying metallic coatings by chemical means, i. via alloy formation and diffusion, such as hot-dip galvanizing or galvannealing.
  • all other means for applying protective layers are included on metal surfaces, such as means for the electrolytic deposition of metal coatings or possibly also means for applying organic coatings (plastic coatings).
  • the process part of the unit for cold rolling comprises at least one cold rolling mill; it is preferably a tandem street, i. several rolling mills arranged one behind the other, for example two to five Duooder Quarto scaffolds assembled together.
  • Fig. 1 shows a plant layout with three parallel treatment units arranged 1,2 3, namely treatment units for a hot rolled steel strip 4.
  • Each treatment unit 1, 2, 3 comprises an inlet part (1E, 2E, 3E), a subsequent process part 1P, 2P, 3P with a process part start 1 Pa, 2Pa, 3Pa and a process part end 1 Pe, 2Pe, 3Pe and an adjoining Outlet part 1A, 2A, 3A.

  • coupling units 11, 12 are arranged at the points (6, 7, 8, 9), where a band flow continuously in an adjacent process unit is to take place.
  • Such a coupling unit 11, 12, which must deflect the band in the embodiment shown by 180 ° preferably consists of two Twisterrollen (see Figures 8 and 9).
  • the pre-strip 4 which is usually wound into a bundle, is unwound before passing through the pickling device 1PBV in the lead-in part 1E by one or two reeling means (not shown), the strip starts being welded to the respective end of a coil (not shown). and conveyed the tape to process part 1PBV. After passing through the process part 1PBV, the strip 4 is cut within the outlet part 1A of the treatment line, which in turn has a reeling device (not shown), and wound up into a coil.
  • This extensive processing should in principle be retained for each unit, although it is canceled according to the invention for a continuous belt flow through a selectable treatment step sequence.
  • three treatment units 1, 2, 3 are arranged parallel to one another in such a way that the basic belt conveying direction (see arrow direction) of directly adjacent treatment units is opposite.
  • the resulting meandering band profile is illustrated in FIG. 1 by means of the arrow course.
  • the coupling of the individual treatment units 1, 2, 3 according to the system layout according to FIG. 1 grants, for example, the production of a galvanized cold strip 13 as an end product in the case of hot-rolled preliminary strip 4.

  • the coupling units 211 are arranged at the transitions 205, 208, 209.
  • means for reversing 215, 216 of the belt conveyor against the original belt conveying direction are arranged at the respective end of a process part. It is clear from the band progression indicated by the arrows that a meandering course also takes place in this plant layout.
  • the starting product is hot-rolled preliminary strip 204, end product is cold-rolled galvanized strip 213.
  • the embodiment according to FIG. 3 is varied by dispensing with the cold rolling treatment unit 202 and the treatment unit 301 for preparation (here pickling unit) is directly coupled to the treatment unit 303 for coating (here hot dip galvanizing unit) by means of the coupling unit 311.
  • Both hot and cold strip 317 for producing galvanized hot or cold strip 318 can be introduced into this plant layout.

  • scale coated hot strip can be placed completely separated from the cold strip treatment in the system and thus accumulating Zunderstaub does not interfere with the cold strip treatment, but can be omitted in this embodiment on the outlet part 619A for economic reasons.
