Definitions

  • the invention relates to a rolling mill, in particular, a CSP-installation for producing strips, in particular, steel for tubes and/or thin strips, including a caster for producing thin slabs and a rolling mill for rolling a thin slab to a strip or thin strip.
  • CSP Cosmetic Strip Production
  • installations are casting and rolling installations in which two separate working steps for production of steel strip are closely connected with each other, namely, the casting of liquid steel in thin slabs in the caster and rolling of thin slabs in steel strip in the rolling installation.
  • the rolling of the previously cast strand is carried out directly with use of the casting heat or by adjusting the desired rolling temperature using a compensation furnace or a heating device between the caster and the rolling mill.
  • Conventional rolling mills of a thick slab installation have at least one roughing stand or heavy-plate stand and a finishing rolling train arranged after the roughing stand or heavy-plate stand at a distance therefrom. While in the roughing stand or heavy-plate stand, the thin slab is rolled, usually in a reversing operation, to an intermediate strip with a predetermined thickness, the rolling in the finishing rolling train takes place in tandem operation, with the finishing rolling train being formed as a continuous rolling train. While the distance between separate stands of such finishing train is usually constant and usually amounts to 5.5 m, the distance between the roughing stand or heavy-plate stand and the first stand of the finishing train is usually many times greater in order to insure the reversing operation in the roughing stand or heavy plate stand. In this connection, the distance between the roughing stand or heavy-plate stand and the finishing train of about 50 m or more is no rarity.
  • Conventional rolling mills have, because of a usually alignment arrangement of the thick slab—extraction roller table of the slab furnace, the roughing stand or heavy plate stand, and the finishing train, a large length, and require powerful stands, so that investment costs are high.
  • conventional rolling mills are inferior in comparison with CSP-installations.
  • the entry temperature in the finishing train is very low, which makes rolling of thin strips difficult.
  • the production of steel for tubes in a conventional hot rolling mill because of the necessary temperature control, is very time-consuming and reduces the production of a conventional rolling mill.
  • the object of the invention to provide a rolling mill of the type described above in which the above-described drawbacks can at least be reduced.
  • the object of the invention is achieved with a rolling mill having features of claim 1 .
  • Advantageous embodiments of the invention are defined by dependent claims.
  • the rolling mill according to the present invention advantageously consists of a compact rolling mill for producing metal strips, especially steel for tubes and/or thin strips, and in which the temperature between two, following one another finishing stands Fi and Fi+1 can be influenced by a rapid heating device, in particular, an induction heating device.
  • a rapid heating device in particular, an induction heating device.
  • a straightening unit preferably, a roller straightening device, and/or shears, or/and, optionally, a descaling sprayer, or another strip cooling device can be arranged between the stands Fi and Fi+1. All of the devices are so compactly located that they fit in the spacing between the stands of 5-25 m.
  • the stand Fi is equipped upstream of the rapid heating device with actuators for influencing the strip warping and/or the ski-phenomenon on the strip head.
  • the roller straightening device and/or the shears and above-mentioned actuators, a reliable passage in a limited space through the rapid heating device, in particular, induction heating device, can be insured with a minimal clearance in the thickness direction.
  • the rapid heating device, the shears, and/or the descaling sprayer is (are) used or are displaced sidewise, dependent on the to-be-rolled product, or there, alternatively, a roller table, with or without heat insulation, or a table can be arranged.
  • shears can be provided between the stands, in order to take care of as straight as possible heads and ends of the deformed strip.
  • a single descaling sprayer is provided, which is formed as a compact device and, advantageously, is arranged before the stand Fi+1 behind the rapid heating device.
  • the descaling sprayer in front of the stand Fi+1 can be activated.
  • the descaling sprayer can be optionally deactivated or removed from the rolling line.
  • a looper can be dispensed with and, instead of it, means for regulating tension, with or without a tension measuring roller, can be provided.
  • the inventive use of a rolling mill preferably, a rolling mill of a CSP-installation with corresponding additional units, noticeably reduces the space occupied by the rolling mill.
  • additional units which are selectively inserted in the finishing rolling mill, advantageously improves the rolling process as with regard to carrying out the process so with regard to obtaining of a corresponding structure.
  • the additional units require, according to the invention, little space and are arranged between two finishing stands, the distance between which amounts to 5-25 m. On the other hand, the space requirement between two stands with additional units is much smaller than the length of the intermediate strip which is rolled there.
  • a thin strip which is cast by a caster of CSP-installation, has a thickness, equal or less than 120 mm.
  • the TM-method (thermomechanical method) in a CSP-installation consists as a rule of a step of one or more deformations of an austenitic initial structure in recrystallization temperature range for producing a uniform, fine, recrystallized austenite structure, and a following step of one or several deformations of the recrystallized, austenitic structure for producing a high-dislocation, extended in an area as much as possible, non-recrystallized austenite structure (so-called pancake structure).
  • these steps can be called conditioning of the austenite.
  • cooling of austenitic structure which has been produced in the first step is carried out for producing a fine-grain structure in the finished hot rolled strip or hot rolled sheet with a phase conversion.
  • the structure of the finished hot rolled strip or hot rolled sheet consists of a combination of ferrite, perlite, bainite, and martensite, wherein the content of these four structure components can, respectively, amounts to between 0% and 100%.
  • a fine recrystallised structure is distinguished by the fact that not only the former, non-uniform cast structure, but also individual coarse grains or structure regions have to be completely transformed into a uniform, fine recrystallised structure with small scatter around the mean grain size. This condition frequently is not fulfilled or is fulfilled incompletely and leads to an inadequately conditioned austenite structure.
  • a step of hot rolling in the non-crystallization temperature range of the austenite follows the step of hot rolling in the recrystallisation temperature range of the austenite, often only little residual deformation for the succeeding actions in the thermomechanical treatment remains when there is a large ratio of the thickness of the finished hot strip or hot sheet and the thickness of the slab or the intermediate strip. Even when individual stands are taken out, this, on occasion, is not sufficient to transform possibly still present residues of the cast structure as well as individual coarse grains or structure regions into a uniform flat pancake structure of non-recrystallised austenite grains. An insufficiently conditioned austenite is also present in this case.
  • Inadequately conditioned austenite has the disadvantageous consequence in the finished hot strip or hot sheet consisting in the presence of individual coarser grains outside the normal distribution about the mean grain size and/or of structure regions having a substructure characterized by small-angle grain boundaries.
  • structure regions of that kind lead to deterioration in the mechanical properties of the strip or sheet, particularly to a reduced toughness.
  • the deformation in the recrystallization range of the austenite is of critical importance for the characteristics of the finished steel strip or sheet.
  • the degree of the deformation required in first step of the thermomechanical treatment can, in fact, be replaced in part by an elevated entry temperature.
  • this possibility is limited by the maximum furnace temperature as well as by the cooling at the time of contact with the roll and by thermal radiation between the stands when several stands participate in this step.
  • a heating device is arranged between two stands Fi and Fi+1 of the rolling mill, in particular between a first stand F 1 and the second stand F 2 . If needed, the heating device can be removed from the rolling mill and again inserted therein.
  • a particularly advantageous is an induction heating device, especially one with one-four induction elements. Altogether, with such heating devices, one strives for a construction as compact as possible with a high power density.
  • the power density lies, advantageously in a range with at least 1500 mw per square meter, preferably, with about 4,000 mw per square meter, when measuring the power density that has been just applied to the strip or induced therein.
  • an inductor element such constructional element is designated through which power is applied to the strip.
  • One or several induction elements can provide induction heating.
  • the rolling mill preferably a continuous rolling mill is used within which the above-described, in the example, deformation steps are used at high temperature and, if needed, with a support of a heating device between the finishing stands and, at an optional cooling of rolls at lower temperatures.
  • a heating device between the finishing stands and, at an optional cooling of rolls at lower temperatures.
  • no roughing stand or heavy-plate stand which is conventional for thick slab installations, is used.
  • the deformation steps are joined together, which means that all of the involved stands are simultaneously operated in accordance with entry of thin slabs or intermediate strips.
  • the rolling stands operate in tandem, so that operationally, the thin slab or the intermediate strip simultaneously passes through common rolling stands. Separate stands can be displaced and, thus, would not take part in the deformation operation.
  • a method in which the cast strand need not be cut in slabs, but rather is continuously, preferably, through a tunnel furnace, is fed to a hot rolling mill, is rolled in a hot rolled strip, is separated before a reel, and is wound in a coil.
  • This process prevents accumulation of scrap as no head or foot ends of a strip are produced.
  • even thinner strips with advantageously a thickness less than 1 mm can be produced because the danger of a rise (hills) during entry of a thinner strip in the last stand of the hot rolling mill at the start is reduced.
  • the feeding speed of the first active stand is reduced to the casting speed which can lead to increased temperature losses before and/or during the hot rolling process.
  • high rolling temperatures and, thus, heating of the strip is necessary to avoid rolling temperatures in the ferrite phase and/or the two-phase area austenite plus ferrite.
  • One of such method and appropriate apparatuses permit in principle the production of different steels with a reduced austenite phase area, e.g., with silicon content of more than 1%.
  • a reduced austenite phase area e.g., with silicon content of more than 1%.
  • higher rolling temperatures are necessary to reliably avoid rolling temperatures in the ferrite phase and/or the intermediate phase austenite plus ferrite.
  • Such steel goods can be produced, without further addition, on the inventive CSP-installation.
  • an induction heating is provided between the front stands or at least in the region between the front stands.
  • the induction heating is provided between the first and second or/and the second and third stands of the finishing mill.
  • the induction heating is characterized by a comparatively small penetration in the thickness direction and is a sensible component.
  • skis or other such strip cambers, or unflatness are present on the head, which endanger passage of tube strips or thin strips through the induction heating means or other units (shears, descaling sprayer) between two finishing stands.
  • ski-up or ski-down phenomenon makes the insertion of the pre-rolled intermediate strip in a following stand very difficult. In an unfavorable case, the intermediate strip can damage the units between the two finishing stands.
  • skis can, e.g., be carried out with hold-down rollers or bending and straightening devices.
  • the pre-rolled intermediate strip heads are cut off by a suitable cutting device.
  • both the head and the end of a pre-rolled intermediate strip can be cut off when thin finished strips are produced in a batch operation.
  • descaling means can be arranged downstream, in the rolling direction, of the heating means for heating the intermediate strip, if necessary, after the strip passes through the heating device and the downstream located drive roller pair and before the intermediate strip enters in one or several finishing rolling stands.
  • the rolling stand itself can have a twin drive and different speed settings on the upper and lower rolls dependent, e.g., on an entry thickness, thickness reduction, material or the temperature, and different diameters of the upper and lower working rolls.
  • the adjustment of slab and strip cooling before the rolling stand Fi can be carried out so that as symmetrical as possible temperature profile over the thickness of the rolled stock is provided, or by a well-aimed temperature trimming, the ski-phenomenon is influenced.
  • trimming of the slab temperatures on upper and lower sides is possible in front of a stand with a heating device.
  • This device for correction or prevention of skis or strip camber in form of a straightening unit can be, in addition to a roller straightening machine, also a hold-down roller, a hold-down plate, a hold-down strut, a bending and straightening machine, a strip head-straightening channel, a strip head pressing device.
  • a ski can be cut off the rolling stock with shears.
  • occurrence of unevenness in the intermediate strip in particular before the entry into the heating device can be detected advantageously with suitable surface distance sensors.
  • suitable sensors such as mechanical, optical, or the like are known to one of ordinary skill in the art.
  • control means which is connected with the sensors, can initiate appropriate measures for eliminating or reducing the detected non-linear strip run, or turn the intermediate strip or slab back.
  • the heating device can protect the above-described devices from damage by strip curvatures, but also the damage, in particular produced by induction heating as a result of cooling water remaining on the strip or thin strip, can be minimized by using suitable blowers advantageously located between the rolling stands of the inventive finishing rolling mill or inserted therebetween.
  • auxiliary units and measures for ski-elimination can be used preferably in a CSP-finishing mill for different application. However, they can also be inserted between the finishing stands of a conventional rolling mill.
  • Induction heating and auxiliary units can be fixedly arranged or displaced in and out from the rolling line.
  • a heat insulation hood is provided as a substitute for the movable units.
