Definitions

  • the invention relates to a rolling train, in particular a CSP plant for the produc- tion of strip, in particular Röhrenstah l, and / or thin strip, comprising a casting apparatus for producing a thin slab and a rolling mill for rolling the thin slab to a strip or thin strip.

  • Conventional rolling mills of a thick slab system have at least one roughing stand or heavy plate framework and one finishing mill behind this roughing stand or heavy plate framework at some distance. While in the roughing stand or heavy plate stand usually reversing the thin slab is rolled to an intermediate strip of predetermined thickness, the rolling takes place within the finishing train in tandem, to which the finishing train is formed as Konti-road. While the distance between the individual stands of such finishing lines is usually constant and is usually about 5.5 meters, the distance between the roughing stand and the first stand of the finishing train is usually many times higher to ensure the reversing rolling operation in the roughing stand or heavy plate stand to be able to. Distances between the roughing stand or plate mill and the finishing mill of about 50 meters or more are not uncommon in this context.
  • the input temperature into the finishing mill is very low, which makes thin strip rolling difficult.

  • a straightening unit preferably a roller leveler and / or scissors and / or optionally a scale scrubber or other belt cooling device between the scaffolding Fi and Fi + 1 may be arranged. All facilities are placed so compactly that they fit into a framework distance between 5 and 25 m.
  • the scaffold Fi in front of the rapid heating device is preferably provided with actuators for influencing the band curvatures and / or skis on the band head.
  • the roller straightening machine, and / or the scissors and the above-described actuators can be guaranteed in the limited space safe passage through the Schnelletzloomvorraum, in particular induction heating, with a minimum passage dimension in the thickness direction.
  • scissors and / or scale scrubber can be used depending on the product to be rolled or driven transversely out of the rolling line or there alternatively be arranged a roller table with or without thermal insulation or table.

  • These auxiliary units require little space in the sense of the invention and are arranged between two finishing stands, whose distance is 5 - 25 m. In other words the space requirement between two scaffolds with the additional aggregates is much smaller than the intermediate strip length rolled there.
  • the thin slab which is preferably produced in the casting device of a CSP plant, has a thickness of ⁇ 120 mm.
  • This provides a CSP system which can be used without the use of a reversing roughing mill, and preferably using just a variety of ready-to-drive-to-drive wheels We produce the desired product range from thick tube tape to thin strip.
  • the method and production of tube tape in a CSP plant may be described.
  • the TM process (thermo-technical process) in CSP plants usually consists of the step of one or more transformations of the austenitic starting structure in the recrystallizing temperature range to produce a uniform, fine, recrystallized austenite structure, and the subsequent step of one or more recrystallized transformations, austenitic structure to produce as flat as possible, dislocation rich, non-recrystallized austenite structure (so-called pan-cake structure). These steps are also referred to as austenite conditioning.
  • the cooling of the austenitic microstructure conditioned by means of the first step for producing a fine-grained microstructure in the finished hot strip or hot sheet in the phase transformation takes place.
  • the microstructure of the finished hot strip or hot plate then consists of the combination of ferrite, perlite, bainite and martensite, wherein the content of these four structural components can be between 0% and 100%.
  • thermo-mechanical hot rolling however, is that to produce the uniformly finely re-crystallized austenite grain in the recrystallizing region as large as possible deformation must be applied.
  • a finely recrystallized microstructure is characterized in that both the former, non-uniform casting structure and individual coarse grains or microstructure areas are completely converted into a uniform, finely recrystallized microstructure with a small scattering about the average grain size. Often, these conditions are not or not fully met and result in insufficient conditioned austenite structure.
  • step of hot rolling in the recrystallizing temperature range of the austenite is followed by a step in the non-recrystallizing temperature range of the austenite, with a large ratio of the thickness of the finished hot strip and / or hot plate and the thickness of the slab or intermediate strip, there is often little residual deformation for the subsequent transformations in the thermomechanical treatment. Even when switching off individual scaffolding this is sometimes not sufficient to convert any remaining remains of the casting structure and individual coarse grains or microstructure areas in a uniform, flat pan-cake microstructure of non-recrystallized austenite grains. In this case too, there is insufficiently conditioned austenite.
  • insufficiently conditioned austenite leads disadvantageously in the finished hot strip or hot sheet to individual coarser grains outside the normal distribution around the mean grain size and / or to the structural regions whose substructure is characterized by small-angle grain boundaries.
  • microstructures lead to poorer mechanical properties of the finished strip or sheet, in particular to a reduced toughness.
  • the deformation in the recrystallizing region of the austenite is of decisive importance for the properties of the finished steel strip or sheet.
  • the degree of deformation required in the first step of the thermomechanical treatment can be partially replaced by a raised inlet temperature, this possibility is limited by the maximum oven temperature as well as the cooling in the roller contact and by thermal radiation between the stands, if involved in this step several scaffolds are.
  • a CSP system is preferred in which a heating device is arranged between at least two stands Fi and Fi + 1 of the rolling train, in particular between the first stand F1 and the second stand F2. If necessary, this heater can also be designed to be retractable out of the rolling train and into it. Particular preference is given to an induction heating device, in particular having one to four inductor elements. Overall, a compact design as possible with high power density is sought in such a heating device. This power density is preferably in a range of at least 1500 megawatts per square meter, preferably about 4000 megawatts per square meter, as measured by the power density actually introduced into the band or induced in the band. In this case, the term inductor element designates that component via which the power is introduced into the strip. One or a plurality of inductor elements may thus form an induction heater.
  • the rolling mill is preferably used as a continuous line, in which the high-temperature forming steps described above in the embodiment are used, and where appropriate with the aid of the heating device between the finishing stands and, in the case of optional cooling, low-temperature rolling becomes.
  • the forming steps are coupled, that is, all scaffolding involved are simultaneously engaged after Dünnbrammen- or Swissbandeinlauf.
  • the rolling stands are driven in tandem operation, thus in a mode of operation in which the thin slabs or the intermediate belt simultaneously pass through all the rolling stands.
  • individual scaffolding can also be driven up and therefore not participate in the forming work.

  • This procedure reduces the amount of scrap because there are no head and foot ends of the band.
  • thinner strip thicknesses preferably with a thickness of ⁇ 1 millimeter, can also be produced, since the risk of cobb les when thin strips are fed into the last stands of the hot rolling mill is limited to starting.
  • Such a method and the illustrated devices also allow in principle the production of steel grades with reduced austenite phase region, for example with silicon contents of> 1, 0 percent.
  • higher rolling temperatures are required for rolling in order to reliably control rolling end temperatures in the ferrite phase and / or in the two-phase region austenite plus ferrite.
