Definitions

  • the invention relates to a rolling train, in particular a CSP plant for producing strip, in particular tubular steel, and/or thin strip, comprising a casting device for producing a thin slab and a rolling train for rolling the thin slab into a strip or thin strip.
  • CSP Cosmetic Strip Production plants are casting-rolling plants in which two separate process stages for the production of steel strips are closely linked, namely casting the liquid steel into thin slabs in the casting plant and rolling the thin slabs into steel strips in the rolling plant.
  • the previously cast strand is usually rolled directly using the casting heat or by setting the desired rolling temperature by means of a soaking furnace or a heating device between the casting plant and the rolling train.
  • Conventional rolling trains of a thick slab plant have at least one roughing stand or heavy-plate stand and a finishing train arranged at some distance behind this roughing stand or heavy-plate stand. While in the roughing stand or heavy-plate stand the thin slab is usually reversingly rolled into an intermediate strip with a predetermined thickness, rolling takes place in the finishing train in tandem operation, with the finishing train being designed as a continuous train.
  • the distance between the individual stands of such finishing trains is usually constant and is usually around 5.5 meters
  • the distance between the roughing stand or heavy-plate stand and the first stand of the finishing train is usually many times higher in order to ensure reversing rolling operation in the roughing stand or heavy-plate stand to be able to Distances between the roughing stand or heavy-plate stand and the finishing train of around 50 meters or more are not uncommon in this context.
  • the rolling train according to the invention in particular a CSP plant, preferably consists of a compact rolling train for the production of metal strips, primarily tubular steel and/or thin strip, in which the temperature between two successive finishing stands Fi and Fi+1 is influenced with the aid of a rapid heating device, in particular induction heating can be.
  • a straightening unit namely a roll straightener
  • a pair of shears and/or optionally a descaler or another strip cooling device can be arranged between the stands Fi and Fi+1. All facilities are placed so compactly that they fit between 5 and 25 m between scaffolding.
  • the stand Fi is preferably provided with actuators for influencing the curvature of the strip and/or skis on the strip head.
  • the rapid heating device in particular induction heating
  • shears and/or descaler can be used depending on the product to be rolled or can be moved out of the rolling line transversely, or alternatively a roller table with or without thermal insulation or a table can be arranged there.
  • the shears can also be provided between the stands for thin-strip rolling in order to be used at the head and/or at the end and to ensure that the heads and ends of the formed strip are as straight as possible.
  • a single-row descaler is preferably provided, which is compact in design and is preferably arranged in front of stand Fi+1 behind the rapid heating device.
  • the descaler can be activated before stand Fi+1.
  • the descaler can optionally be deactivated or moved out of the rolling line.
  • a looper can optionally be dispensed with, instead of which a minimum tension control with or without a tension measuring roller can be provided.
  • a rolling train according to the invention preferably the rolling train of a CSP plant with the corresponding additional units, significantly reduces the installation space of a rolling train overall.
  • the use of additional units within the finishing train which can optionally be moved into the rolling line, can advantageously support the rolling process overall, both with regard to the process control and with regard to the microstructure adjustment in the rolled product.
  • these additional units require little installation space and are arranged between two finishing stands which are 5-25 m apart. In other words, the space required between two stands with the additional units is much smaller than the intermediate strip length rolled there.
  • the thin slab preferably produced in the casting device of a CSP plant preferably has a thickness of ⁇ 120 mm. This provides a CSP plant which is capable of producing the desired range of products from thick tube strip to thin strip without the use of a reversing roughing stand and preferably solely using a large number of finishing stands as a rolling train.
  • the process and manufacture of tube strip in a CSP plant can be described.
  • the TM process (thermomechanical 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 transformations of the recrystallized, austenitic microstructure to produce an austenitic microstructure that is as flat as possible, rich in dislocations and non-recrystallized (so-called pan-cake microstructure).
  • These steps are also referred to as austenite conditioning.
  • the austenitic structure conditioned by means of the first step is cooled to produce a fine-grained structure in the finished hot strip or hot sheet during the phase transformation.
  • the microstructure of the finished hot-rolled strip or hot-rolled sheet then consists of a combination of ferrite, pearlite, bainite and martensite, whereby the content of these four microstructure components can be between 0% and 100%:
  • the above step of forming in the non-recrystallizing temperature range of the austenite can also be omitted.
  • the conditioning of the austenite takes place entirely in the austenite's recrystallizing temperature range.
  • step of hot rolling in the recrystallizing temperature range of austenite is followed by a step in the non-recrystallizing temperature range of austenite, with a large ratio of the thickness of the finished hot strip or hot sheet and the thickness of the slab or intermediate strip, there is often only little residual deformation for the subsequent deformations in thermomechanical treatment. Even if individual stands are switched off, this is sometimes not enough to convert any residues of the cast structure and individual coarse grains or microstructure areas into a uniform, flat pan-cake microstructure of non-recrystallized austenite grains. Insufficiently conditioned austenite is also present in this case.
  • insufficiently conditioned austenite disadvantageously leads to individual, coarser grains outside the normal distribution around the mean crown size and/or to microstructure areas in the finished hot strip or hot sheet, the substructure of which is characterized by small-angle grain boundaries.
  • such structural areas lead to poorer mechanical properties of the finished strip or sheet, in particular to reduced toughness.
  • the deformation occurs in the recrystallizing
  • the austenite range is of crucial 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 an increased entry temperature, this possibility is limited by the maximum furnace temperature as well as by the cooling at roll contact and by thermal radiation between the stands when several stands are involved in this step are.
  • a CSP plant 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 required, this heating device can also be designed so that it can be moved out of and back into the rolling train.
  • An induction heating device in particular with one to four inductor elements, is particularly preferred. Overall, the most compact design possible with a high power density is sought in such a heating device.
  • the component through which the power is introduced into the band is referred to as the inductor element.
  • One or a plurality of inductor elements can thus form an induction heater.
  • the rolling plant is preferably used as a continuous train, within which the forming steps described above in the exemplary embodiment are applied at high temperature and, if necessary, with the support of the heating device between the finishing stands and with optional cooling, rolling at low temperature.
  • the forming steps are preferably coupled, ie all the stands involved are engaged at the same time after the thin slab or intermediate strip infeed.
  • the roll stands are run in tandem operation, i.e. in an operating mode in which the thin slabs or the intermediate strip pass through all the roll stands at the same time.
  • individual scaffolding can also be driven up here and therefore not participate in the forming work.
  • a method can be used in which the cast strand does not have to be cut to length into slabs, but rather is fed continuously, preferably through a tunnel furnace, to the hot rolling mill and for this purpose the hot strip is finish-rolled, cooled and cut to length before the coiler and then is wound into coils.
  • This mode of operation reduces the amount of scrap, since there are no top and bottom ends of strip.
  • thinner strip thicknesses preferably with a thickness of. ⁇ 1 millimeter can be generated, since the risk of cobbles when thin strips enter the last stands of the hot rolling mill is limited to the start-up.
  • endless rolling the infeed speed of the first active stand is reduced to the casting speed, which can lead to increased temperature losses before and/or during hot rolling. Therefore, higher rolling temperatures and thus heating of the strip are required for rolling in order to avoid final rolling temperatures in the ferrite phase and/or in the two-phase region austenite plus ferrite.
  • an induction heating system is advantageously installed between the front stands or at least inserted into the area between the front stands.
  • Induction heating is preferably used between the first and second and/or the second and third stand of a finishing train.
  • an induction heater is characterized by a comparatively small passage dimension in the thickness direction and is a sensitive component.
  • skis or other strip curvatures or imperfections often occur at the head, which endanger the safe passage of the tubular strip or thin strip through the induction heating or other units (shears, descaler) between two finishing stands .
  • the above-mentioned ski-up or -down phenomenon can make it very difficult to thread the pre-rolled intermediate strip into a subsequent stand. In the worst case, the intermediate strip damages units between the two finishing stands.
  • the ski is minimized or eliminated by means of a roller straightening machine.
  • the pre-rolled intermediate strip head is cut by means of a suitable shearing device within the system according to the invention.
  • a pre-rolled intermediate strip can also be cropped at the head and ends with such shears if thin finished strips are to be produced in batch operation.
  • Measures on the roll stand itself include installing a twin drive and different settings for the roll speed on the top and bottom rolls depending on, for example, the entry thickness, the reduction in thickness, the material or the temperature, as well as different diameters of the top and bottom work roll ah.
  • the slab or strip cooling system upstream of the rolling stand Fi can be adjusted in such a way that a temperature profile that is as symmetrical as possible is created over the thickness of the rolled product or is influenced by targeted temperature trimming of the skis.
  • trimming of the slab temperatures on the top and bottom is also possible for this purpose in front of the stand with a heating device.
  • this device for correcting or avoiding a ski or a belt curvature in the form of a straightening unit is a roller straightening machine.
  • a ski can be cut out of the rolling stock using scissors.
  • the occurrence of unevenness in the intermediate strip can preferably be detected by means of suitable surface distance sensors, in particular before it enters the heating device.
  • suitable sensors are mechanical, optical or other sensors known to those skilled in the art. Based on an alarm signal from a controller connected to the sensors, suitable measures to eliminate or reduce the detected uneven strip course can be initiated or the intermediate strip or slab can be rejected again.
  • the heating device be protected from damage caused by bending of the strip in the manner described above; Damage, in particular to induction heaters, by cooling water remaining on the strip or thin strip can also be avoided by using suitable blow-off devices, which are also particularly advantageously arranged between the roll stands of the finishing train according to the invention or can be moved into this location.

  • the distance between stands Fi and Fi+1 is between 5 and 25 m.
  • strip 1 runs into an induction heater 8 and then into a pair of driver rollers 12 .
  • a strip tension can be applied to the strip 1 (even before it reaches the strip head in the subsequent stand) and, in addition, any water remaining on the strip 1 can be easily squeezed out.
  • a minimum tension control can be set up between stands Fi and Fi+1.
  • the pair of pinch rollers 12 helps to set an exact setting speed on the stand Fi+1.
  • a tension measuring roll or looper (not shown) is arranged between the stands to ensure mass flow.
  • a cooling section 11 is arranged for an application example, with which the strip 1 heated in the heating device 8 to a temperature above the recrystallization temperature is cooled to a temperature range in the non-recrystallization range for a previously heated application example.
  • the two devices 8 and 12 can also be arranged in reverse.
  • the arrangement of pairs of driving rollers 12 in front of and behind the heating device 8 is also conceivable.
