Definitions

  • the invention relates to a method for the alternative production of a hot-rolled strip, a thermoformed pre-strip or an undeformed steel slab with the aid of the continuous casting method, and an installation for carrying out the method.
  • a process for producing a hot-rolled strip with the smallest possible thickness using the continuous casting process and subsequent rolling of the continuous cast product is known from PCT publication WO 92/00815.
  • the cast product is subjected to a first shaping step after leaving the continuous mold, in which the cast product still has a liquid core.
  • a further deformation step is carried out by rolling the solidified cast product, which is then heated to the hot rolling temperature and wound into a bundle. A final hot rolling then takes place.
  • the known method not only requires a structurally complex system, but is also complicated in terms of control technology and requires a large number of control technology devices to be implemented. Accordingly, it requires a considerable investment. Furthermore, there is a great deal of uncertainty in production, since the large number of continuously operating drive units in the event of a failure of some of the entire process is stopped and the casting process has to be stopped.
  • the known method there is no flexibility with regard to product quality and the quality of the manufactured products.
  • the first deformation step must always be carried out, otherwise one for winding required thinness of the product and thus production cannot be guaranteed.
  • the known method cannot therefore be carried out for certain steel qualities.
  • targeted and flexible temperature control is hardly possible, especially in the case of transient conditions. If the winding unit fails, the entire process comes to a standstill immediately: this also includes the standstill of the casting process.
  • a method for producing a tape with a thickness of 2 to 25 mm is known from EP-B - 0 286 862.
  • a steel strand is formed by pouring melt into a funnel-shaped continuous mold and is already deformed as it passes through it.
  • the strand which still has a liquid core, is pressed together after exiting the continuous mold in such a way that the inner walls of the strand shells which have already solidified are welded together. This results in a reduction in thickness to a thickness of less than 25 mm.
  • this known method can only be used for very specific steel qualities, namely those which allow such deformation just below the continuous mold.
  • the funnel-shaped continuous mold does not allow a uniform flow distribution, ie the casting shell emerging from the dip tube can weaken the strand shell, which is already heavily used, at the critical deformation points by melting become what is expressed in increased risk of breakthrough.
  • Another disadvantage is the very low flexibility with regard to the production capacity and with regard to the utilization of the full casting speed range.
  • EP-B-0 327 854 discloses a method for rolling pre-strips cast on a continuous strip casting installation, the cast pre-strip being brought to the rolling temperature in a continuous operation and being introduced into the finishing mill for rolling out.
  • the invention aims to avoid the disadvantages and difficulties described above and has as its object to provide a method and a system for carrying out the method, which enable the production of the thinnest possible tapes with high product quality, with a very high operational flexibility. In particular, it should be possible to continue the continuous casting in the event of a malfunction at a deformation stage downstream of the continuous mold.
  • plate molds with plane-parallel walls can be used.
  • this results in the formation of a uniform strand shell.
  • This is neither deformed nor squeezed in the continuous mold because it has a constant cross-section.
  • the strand emerging from the continuous mold has a strand shell of the highest quality, so that the risk of breakdown is minimized and a deformation of the strand, which still has a liquid core, without any risk of breakdown is possible.
  • the first and the second deformation step are preferably carried out individually or together depending on the steel quality, taking into account their deformation properties under the temperature conditions prevailing in these deformation steps, expediently for high-alloy or high-carbon structural steels, for high-strength tubular steels, for austenitic steels and for duplex steels only the second and third deformation steps are carried out.
  • the first deformation step is carried out immediately after the strand has left the mold, the first deformation step advantageously being carried out in a plurality of substeps.
  • Descaling is expediently arranged upstream of the second deformation step.
  • a temperature homogenization of the separated strand pieces is expediently carried out before the third deformation step.
  • the high flexibility of the method according to the invention enables the thickness of the strand to be reduced down to a thickness of 30 mm or above, preferably by the first two method steps, applied individually or together.
  • the cut strand piece thus has a thickness of at least 30 mm before it is fed to further rolling. If the first two deformation steps are switched off, this thickness can be reduced to the casting thickness, i.e. up to a maximum of 150 mm, in particular 100 mm.
  • the first deformation stage preferably has rollers that can be adjusted hydraulically against one another and bring about the deformation of the strand.
  • a device for temperature homogenization of the separated strand pieces such as a temperature compensation furnace, is advantageously provided between the separating device and the third deformation stage, the device for temperature homogenization expediently being provided with a storage device for holding a plurality of separated strand pieces.
  • a continuous mold for continuous steel casting which has a constant cross section and is preferably designed as a plate mold.
  • cast strands in a thickness 2 between 60 and 150 mm, preferably in a thickness between 60 and 100 mm can be cast.
  • the use of a conventional dip tube 3 is possible, which results in stable operating conditions in terms of cooling and melt distribution, so that the one leaving the continuous mold 1 Strand 4 has a uniform and stable strand shell.
  • a vertical support frame 5 is arranged to form a first deformation stage, which has hydraulic (as indicated by pressure cylinder 6) support rollers 7 which can be adjusted to the strand shell.
  • This vertical support structure is divided into two sub-segments 5 ', 5' ', so that different forces can be applied to the strand 4 with each sub-segment.
  • a so-called “soft reduction” of the solidifying strand 4 with a still liquid core is carried out as the first deformation step, the load on the strand shell in the two-phase boundary layer remaining below a limit strain which influences the end product quality.
  • this so-called “soft reduction” the strand thickness can be reduced by up to 30 mm without any loss of quality.
  • further arc segments 8, 9 are provided, which may also have hydraulically adjustable support rollers 7.
  • the strand 4 After the strand 4 has been deflected into the horizontal, it is passed through a simple (possibly multi-stage) deformation framework 10 which can be activated as a second deformation stage (second deformation step) to deform the strand 4, which has already solidified.
  • This achieves a thickness 12 of a pre-strip corresponding to the required hot strip thickness with a stitch reduction of up to a maximum of 60% (e.g. 70 to 30 mm).
  • the strand 4 Before passing through the deformation framework 10, the strand 4 is subjected to descaling in a descaling device 11, which enables soft descaling by means of rotating descaling nozzles and with special water wipers for the descaling water.
  • the thickness pre-reduction allows the end product quality to be influenced, in particular for micro-alloyed steels, which are usually influenced by corresponding decreases in the stitches above the recrystallization stop temperature, by precipitation and recrystallization processes.
  • the strand 4 preferably has the format of a pre-strip, that is to say a (non-windable) pre-material for the production of the strip.
  • the thickness 12 is preferably 30 mm and more.
  • a separating device 13 Downstream of the deformation stand 7 is a separating device 13 for the transverse division of the cast strand 4, the strand 4 deformed depending on the requirements of the end product in the continuous casting installation being separated in the coil weights by means of hydraulic scissors.
  • the resulting strand pieces 14 with a thickness of 30 to 150 mm then run into a transport and homogenization device, e.g. a roller hearth furnace 15, which, depending on the slab temperature, is also able to heat a thin slab.
  • a transport and homogenization device e.g. a roller hearth furnace 15, which, depending on the slab temperature, is also able to heat a thin slab.
  • the entire cross section of the strand piece 14, in particular the edges thereof is brought to a uniform temperature.
  • the strand pieces can be buffered (stored, e.g. by stacking), i.e. in the event of brief faults in a part of the plant, thin slabs or strand pieces 14 are picked up until the production process is resumed.
  • a further separating device which is designed as hydraulic scissors 16, is provided, which is activated in the event of a malfunction in the subsequent rolling mill stage 17, which acts as the third deformation stage.
  • descaling takes place in a descaling device 18, which is preferably a rotor descaling with low water consumption and the resulting low temperature drop with excellent descaling effect.
  • the strand pieces are rolled in the rolling mill stage 17, which consists of finishing stands 19.
  • the number of finishing stands 19 of the finishing train results from the thickness 12 of the strand pieces 14 after separation from the casting strand 4 and the strip thickness 20 to be rolled.
  • the strand pieces 14 do not undergo ⁇ - ⁇ conversion until that point in the manufacturing process at which the ⁇ - ⁇ conversion due to material science processes to achieve the required mechanical-technological parameters and the toughness for the steel grade produced.
  • the finishing mill can be replaced by a Steckel mill for smaller capacities. This option is preferably used for the production of hot strips from stainless steel or special steel from thin slabs.
  • the rolled strand piece 14 After exiting from the rolling mill stage 17, the rolled strand piece 14 is cooled to reel temperature in a cooling section 21 (laminar cooling section) and wound into a bundle 23 by means of a reel device 22.
  • the finished rolled strip is labeled 24.
  • the possible combinations of the three deformation stages according to the invention increase the overall system flexibility, since even without a "soft reduction" (first deformation step) with liquid sump or rolling after solidification (second deformation step), the overall process remains in operation without loss of quality and performance.
  • first deformation step with liquid sump or rolling after solidification
  • second deformation step the overall process remains in operation without loss of quality and performance.
  • the activation of all deformation stages is only necessary for approx. 15 to 20% of the total production, namely for that part of the production that is to be rolled to a final thickness that cannot otherwise be reached with the finishing train.
  • the arrangement permits energy optimization of the overall process by balancing the casting thickness (D) and the final thickness (P) with the aim of bringing the greatest possible enthalpy of the strand pieces into the roller hearth furnace 15. This is achieved through a dynamic cooling regime using air-water nozzles to increase the exit temperature of the strand and the "soft descaling".
  • the variety of the method according to the invention is documented in the table below.
  • the smallest achievable strip thicknesses with a casting thickness of 70 mm are given in horizontal lines for different steel qualities, whereby it is additionally indicated which of the first two deformation stages is activated.
  • the first deformation stage - with a thickness reduction of 10 mm - is designated I and the second deformation stage - with a thickness reduction of 20 mm - with II. If the corresponding deformation level is activated, this is marked with an X, if it is not activated, it is marked with a 0.
  • An N indicates that these strip thicknesses should not be produced solely by the process steps according to the invention.
  • the third deformation stage (rolling mill stage 17) is always in operation with five to seven finishing stands 19 for the dimensional ranges specified in the table.
