  • the invention relates to a method and a plant for producing a metal strip, preferably a steel strip, in particular of stainless steel and Carbon steel, with a casting thickness of 1.0 mm to max. 20 mm, preferably 1.5 mm up to max. 12 mm and excellent surface quality using the Two-roll casting and other treatment stages with the characteristics of Preliminary terms of independent claims 1 and 14.
  • the object of the invention is therefore to avoid these disadvantages and a method and to propose a plant of the type described above, in which the in the Casting system formed metal strip largely stress-free and without repercussions from subordinate institutions the first cooling and microstructure phase passes. Furthermore, it is an object of the invention, the dead weight of the Metal band in this phase to keep the metal band formation as constant as possible and still the transport speed in downstream facilities vary too can. Furthermore, an optimization of the production process under the Viewpoint consistent highest band quality can be achieved.
  • the driving roller stand takes place in directly successive treatment steps.
  • the definition of the band position by the formation point of the metal strip in the casting gap the two-roll caster and the first clamp in the first capstan allows the determination of an optimal corridor, essentially one Quarter arc corresponds, in which the metal strip für technologicallydert largely stress-free is and even if the transport speed of the metal strip in the first Drum roller frame is regulated in dependence on the casting speed.
  • the Arrangement of a first driving roller stand for receiving and regulated forwarding the metal band before its temporary storage as a freely hanging band loop in a loop pit prevents repercussions of its own weight and Loop motion on the delicate first cooling and structure formation phase.
  • the position of the metal strip in the region of the deflection from the vertical to the horizontal direction preferably the Aufliegestelle of the metal strip on a deflection support device with a Tape detection device detected metrologically and the tape transport speed in first traction roller frame and / or the casting speeds in the casting gap in Depending on regulated.
  • a deflection support device which as arcuate Guiding scaffold is formed and pivotally mounted in the plant structure and is only over a part of the way from the first drive roller frame to Two-roller caster extends, the controllability remains in a narrow, however sufficient area.
  • the winding of the metal strip under train can be advantageous depending on the transport speed of the metal strip in the first or in second traction roll stand, possibly taking into account the Casting speed, to be regulated.
  • the casting thickness and the strip thickness are coordinated with one another, that the thickness reduction takes place in a rolling pass.
  • the metal strip between the two-roll caster and the first capstan a Inert Deutschenshunt with for the metal strip Oxidationsvermeidender or at least undergoes oxidation-inhibiting atmosphere by appropriate fluids (gas mixtures or liquid mixtures) introduced or with the hot metal strip in direct Contact is brought.
  • appropriate fluids gas mixtures or liquid mixtures
  • the metal strip is placed in front of the Winding up according to given bundle weights divided and if necessary the Band edges trimmed.
  • a plant for producing a metal strip, preferably a steel strip, which meets the stated task, is characterized by the characteristics of independent claim 14.
  • the first traction roller frame is immediately upstream of the tape storage and the second drive roller frame immediately downstream of the tape storage.
  • the two drive roller stands as input side and Output side pulleys positioned on the tape storage.
  • Preference is for deflecting the cast metal strip from the vertical Casting in a substantially horizontal transport direction between the Zweiwalzengitinnate and the downstream first drive roller stand a from a corridor formed in a quarter arc, at least in a sub-area is formed by a deflection support device.
  • a rolling mill for thickness reduction and structural transformation arranged on the cast metal strip is advantageous from a single rolling stand, preferably formed a quarto rolling mill.
  • the Rolling device heating preferably one engageable with the work rolls associated induction heater or gas burner.
  • the second drive roller frame of the rolling mill is a Temperaureinstell Road, in particular a band heater for Band temperature increase, preferably upstream of a band edge heating.
  • One Drive motor of the second drive roller frame is with the drive of the rolling mill through a regulating device coupled so that the metal strip in the Temperature adjustment and / or in the rolling mill is kept under train.
  • the metal band passes through one between the two-roll caster and the first capstan arranged oxidation-preventing or at least oxidation-inhibiting Inerting.
  • the tape storage between the first capstan and the second drive roller frame is also formed as an inerting chamber.
  • the Inertleitershuntn can also be used as a temperature equalization zones be, and have appropriate facilities for the cooling or heating of the inert gas.
  • the rolling mill is a belt cooling line for controlled cooling of the Subordinated metal band.
  • a cross-cut device and optionally a Bandbeklamvorraum the tape winding device are arranged upstream and it is at least before and after the Querteilvortechnisch Drive roller stands arranged, the rolled strip during the cut under train hold.
  • an intermediate vessel for the melt transfer and arranged above this a ladle for the melt supply.
  • the Ladle is supported in a cantilever arm of a ladle turret, which is around a vertical axis from a pouring position to a ladle change position and back is supported pivotally.

  • Fig. 1 shows a plant according to the invention for producing a metal strip 1 of a few Millimeters thick starting from a two-roll caster 2, passing through the two Casting rollers 3, 4 is indicated schematically. Melt is via an intermediate vessel 5, which flows from a ladle 6, the two-roll caster 2 is supplied.
  • FIG. 3 shows a ladle turret 7 carrying the ladles 6, in order to show the same vertical axis it is rotatably supported.
  • the metal band 1 is in the two-roll caster 2 along the lateral surfaces of the casting rolls 3, 4th formed and discharged by the rotation down.
  • the metal band will be in a quarter arc in horizontal direction and there deflected by a first Stem roller frame 8 detected and immediately trained in a loop pit Tape storage 9 forwarded.
  • the metal strip detected by the second traction roller frame 10 and fed to a tape winding device 11.
  • the metal band 1 is wound into coils.
  • One of the coil winding device 11 upstream Bandbeklad- and cross-cutting device 12 with upstream and downstream Drive roller stands 13, 14 is shown only in Fig. 3.
  • a control device 15 connects a rotary drive of the casting rolls 3 with the Rotary drive of the first drive roller frame 8 and allows a largely constant Tape guide between two-caster casting machine 2 and first drive roller frame 8.
  • a second control device 16 regulates the reel speed and the Transport speed in the second drive roller frame 10 as a function of Transport speed in the first drive roller frame 8 and / or the Casting speed.
  • FIG. 2 shows a further embodiment with an improved process control system.
  • a Bandortungssystem 17 is arranged, which is the instantaneous position of the Metal strip 1 determined in this area. This can be done, for example, by optical, thermal, acoustic or mechanical measuring methods take place. It is special to choose a measuring device that has a higher thermal stress withstand.
  • the band positioning system is control technology with the control device 15th connected.
  • a deflection support device 18 leads the Metällband surface gentle to the first traction roller frame 8.
  • Fig. 3 illustrates a plant with the involvement of a rolling mill for the production a rolled metal strip with excellent rolling texture and excellent Surface quality, comparable to a conventional cold-rolled metal strip.
  • the second traction roller stand 10 is one formed by a single quarto skeleton Subordinate rolling mill 19.
  • the work rolls 20 may not shown Heater facilities be equipped.
  • the rolling mill 19 is a temperature adjusting device 21 directly upstream, directly to the second drive roller frame 10th followed.
  • the drive motor of the second drive roller frame 10 is connected to the drive of Rolling mill 19 coupled by a control device 24 so that the metal strip in the Temperature adjustment 21 is held under train. This is an optimal Temperature control ensured in the rolling mill 19.
