Definitions

  • the subject of the invention is a rolling process and installation.
  • metal strip cold specially adapted for production annual average level, for example between 300,000 tonnes and a million tonnes.
  • the invention applies in particular to pickling and rolling of steel sheets and strips obtained by hot rolling or casting continues thin.
  • the hot product is subjected, successively, a pickling treatment for the elimination of the scale, cold rolling until the thickness is obtained desired and possibly finishing treatments which depend the type of sheet to be produced, for example annealing, galvanizing or other surface treatment.
  • Cold rolling is normally carried out in several passes successive, either in two opposite directions on a reversible train, or on several rolling mill stands operating in tandem.
  • a coupled online installation of this type includes, in general, an entry section comprising a device for unwinding, one after the other, of coils to be treated, a section of pickling to remove scale, usually by immersion of the strip in a chemical pickling liquid, a section of cold rolling and an outlet section comprising means winding the rolled strip into a reel.
  • the section input comprises means of connection, by welding or stapling, of the downstream end, in the direction of travel, of a first coil with the upstream end of the next coil.
  • a band is thus produced continuous which scrolls successively in the different sections of the line.
  • the same scrolling speed for example 400 m / min or even more, is maintained until the entrance of the rolling mill and then increases as the thickness is reduced.
  • the strip is rewound again to form a coil and when it reaches its length maximum, the strip must be sheared to allow the evacuation of the coil wound.
  • it is advantageous to use a so-called "flying" shear made up of two blades mounted respectively on two rotary drums, but the speed must, however, be reduced.
  • two working winders can be used alternatively, with a referral system which allows, after the shear and immediately direct the upstream end of the strip next to the second winder for winding the new one reel, the withdrawal of the reel wound on the first winder being performed in masked time.
  • You can also use a so-called carousel comprising two operating winding mandrels alternately.
  • such a coupled line must include at minus two accumulation means placed, respectively, at the entry and at the exit of the treatment section. So before we get to the end of a coil, we accumulate a certain length of tape which will continue to scroll through the processing section during the time necessary for connection with the end of the next coil. Of even, in case of shutdown of the rolling mill, for example for replacement cylinders, it is possible to continue scrolling the strip in pickling tanks, accumulating the pickled length at the outlet of the processing section.
  • the input accumulator of the section of be emptied so as to be able to compensate for variations in subsequent speeds.
  • the invention relates to a method new implementation of a coupled line making it possible to reduce enough investment and operating costs to that an average production is profitable.
  • the invention therefore applies to a coupled online installation comprising, as usual, a strip entry section processing, a cold rolling section and an outlet section.
  • the composition of the fluid is determined treatment so that the metal of the strip is not attacked during a residence time in the corresponding treatment section at a minimum running speed of the order of a few meters per minute, and the rolling conditions are determined so that the desired quality of the tape can be maintained at a speed minimum rolling down to 1 meter per minute.
  • the coupled lines current ones have a very large capacity, exceeding, for example, 150,000 tonnes per month and therefore operate at a very high speed.
  • the rolling mill must be capable of achieving a rate of significant thickness reduction and usually includes four or five cages operating in tandem. This results in variations significant line speed
  • the average strip rolling speed can go from 500 to 1500 m / min at the exit of the rolling section while the running speed in the stripping section must necessarily stay lower, for example from 100 to 400 m / min.
  • the accumulators must therefore have a very large capacity, of the order of 400 to 600 m and constitute extremely bulky and complex installations, comprising multiple levels of tape travel between a series of rollers fixed deflectors and a series of movable rollers which can be move longitudinally to vary the lengths of the different levels.
  • the production capacity of an installation being, width and equal thickness, proportional to the running speed, and times necessary stopping of the strip, at the entry and the exit of the line, being the same, the capacity to give to accumulators is, normally, more or less proportional to the tonnage to be achieved. Therefore, for a installation producing 400,000 tonnes per year, i.e. around 20% of the capacity of the current coupled lines, one should, normally, reduce the capacity of the batteries in the same proportion, which leads to a dimensioning from 80 m to 120 m. Such accumulators are still very bulky and expensive and for this reason in particular, it did not seem possible, until now, to make a profit a coupled line for an annual production of less than 1 million tonnes.
  • the inventor had the idea of deviating from the usual operating conditions by choosing, on the contrary, to conduct operations in a manner that is possible while maintaining the desired quality of the tape, to use simple equipment and little expensive to sufficiently reduce costs investment, operation and maintenance so that such coupled line is profitable even for medium capacities.
  • relative scrolling speeds, respectively in the inlet section, the processing section, the laminating section and the output section are adjusted so that the difference in speeds between two successive sections during a operating phase corresponds to scrolling, in the most fast, with an additional strip length not exceeding a few tens of meters.
  • the invention allows the use of accumulators of reduced capacity, for example a few tens of meters, and much simpler constitution.
  • the frame rates can be reduced considerably even in the rolling section, and so it's possible, at the exit of this one, to use a shears of the fixed type cutting the tape at a speed not exceeding one meter per minute, as well as winding means comprising a single winder.
  • the maximum frame rates, respectively in the section entry and into the rolling section may not exceed more than 10% the maximum scrolling speed in the section of treatment. Under these conditions, the accelerations can be reduced and we can use lower power motors and therefore, less expensive.
  • the capacity planned for one installation according to the invention corresponded substantially to the capacity a coating or continuous annealing line. Because of this, it will possible to associate with an installation according to the invention other switchgear placed downstream of the rolling section and allowing subject the strip to various finishing treatments, depending on the quality desired. Indeed, the operation of a coupled capacity line medium according to the invention has sufficient flexibility for allow the incorporation of coating equipment on the same line with annealing, for example, a galvanizing line.
  • Figure 1 is an overall diagram of an online installation coupled according to the invention.
  • Figure 2 is a diagram illustrating the manufacturing capacity of an installation according to the invention, with a rolling stand equipped with working cylinders with a diameter of 320 mm.

  • FIG. 1 the whole of a coupled line according to the invention comprising successively, along a longitudinal direction of travel of the metal strips, a strip entry section 1, processing section 2, section cold rolling 3 and an outlet section 4.
  • section 1 entry and preparation of the strip M comprises a reel unwinder 10, a device 11 for strip-stripping of the strip, a trimmer shears 12 and a welding device 13.
  • a reel unwinder 10 a device 11 for strip-stripping of the strip
  • a trimmer shears 12 a welding device 13.
  • the ends are first trimmed by the shears 12 so as to produce two parallel edges which are welded in the welder 13. This welding can be carried out by any adequate means, the shears 12 and the welder 13 can be grouped together in the same machine.
  • the strip then runs through a processing section 2 which is usually consisting of several trays 21, 22, 23 the number of which and the length are determined according to the desired hourly tonnage and the expected frame rate.
  • a processing section 2 which is usually consisting of several trays 21, 22, 23 the number of which and the length are determined according to the desired hourly tonnage and the expected frame rate.
  • a chemical pickling fluid for example hydrochloric acid, the composition of which is determined for ensure the complete elimination of the scale taking into account the time of stay of the strip in the acid, which depends on the running speed.
  • calamine can be fractionated mechanically, for example by shot blasting.
  • the pickling section ends with a edge shearing equipment 26 for products requiring width setting in this production line.
  • a tape guiding device 25 Upstream of the shears banks is installed a tape guiding device 25 allowing to ensure a good centering of the strip and a setting to width with a minimal loss of metal.
  • the cold rolling section 3 includes a rolling mill 30 in front which is placed a traction device 31 for submitting the strip, during rolling, at a controlled tensile force.
  • the rolling mill 30 is normally made up of several rolling stands 33, 34 operating in tandem but it should be noted that, in the invention, the rolling mill may have only two stands 33, 34.
  • a tape guiding device 32 At the entrance to the rolling mill 30 a tape guiding device 32 for ensuring the centering of the strip and its correct travel between the cylinders of job.
  • the laminated strip finally passes through an exit section 4 comprising a winder 42 in front of which is placed a roll deflector 41.
  • the winder 42 consists of a mandrel driven in rotation about its axis and on which the end of the strip engages to roll up.
  • a shear 43 is disposed on the path of the strip upstream of the deflector roller 41 and the winder 42 is associated with means not shown evacuation of the coils and means for engaging the end of the next spool on the reel spindle.
  • this includes several tensioning devices, respectively, 14 at the entry of the first accumulator 6, 24 at the exit of the section of pickling 2 and 31 at the entrance to the rolling section 3.
  • a device for guide 15 is placed at the entrance to the first pickling tank 21 to compensate for the geometric defects of the strip by ensuring the maintenance of the latter on the scroll axis, over the entire length of the trays 21, 22 and 23.
  • the stripping section 2 ends, as usually by edge shearing equipment 26 for products requiring a lay-off in this production line and a tape guiding device 25 is installed upstream of this shearing equipment 26 to ensure correct centering of the strip and setting to width with minimal loss of metal.
  • a tensioning device 31 is placed at the entrance to the section of lamination 3 so as to isolate the level of traction from the second tape accumulator 7, which is relatively low, of that of the section rolling which must be high enough at the entrance to the rolling mill 30 to allow the necessary reduction rate in the first cage.
  • a tape guiding device 32 is also placed at the entrance to the rolling mill 30 to ensure good travel of the strip up to the winding section 4.
  • An installation according to the invention therefore comprises, in its different sections, the equipment that we usually find in the coupled lines but, as we will see now, the operations are carried out in such a way as to simplify the whole of the installation.
  • the inhibitor product (s) added in the treatment bath are used under normal conditions of operation and during each winding cycle of a reel, to reduce the frame rate in the treatment section up to a speed of a few meters per minute, the minimum speed even being 1 to 2 meters per minute, whenever the tape has to be stopped or slowed downstream or downstream of the treatment section.
  • the presence of the product (s) inhibitors in the treatment bath allows, indeed, to admit a fairly long strip residence time in the pickling tanks without risk of metal loss, only the scale being attacked.
  • an accumulation capacity of 10 m in the second accumulator 7 placed downstream of the processing section 2 allows the rolling mill to stop for 5 to 10 minutes, for example for the evacuation of a reel of the rewinder 42.
  • the speed of scrolling in the rolling mill 30 can also be reduced.
  • rolling mill stands for example of the quarto type, can be equipped with flatness control means by bending of the working cylinders and / or by the use of support with rotating shell and controlled deformation of the type produced by the applicant company and known under the name "DSR" (registered trademark).
  • DSR registered trademark
  • the scrolling speed can be reduced to a few meters per minute, not only in the stripping section 2 but also in the rolling section 3, without stopping rolling.
  • the tape running in the processing section can be stopped or, at least, slowed down to a very low speed.
  • the accumulators 6 and 7 can be of the vertical type with two strands with a vertically movable deflector roller.
  • Such an accumulator 7 also makes it possible to stop, during a few minutes, the scrolling of the strip in the section of pickling 2, for example for an adjustment intervention on the shears edge 26, continuing rolling at very low speed.
  • the motors of control of the different equipment must have a very high power high to allow very large speed variations with high acceleration rates in order to get through the stages of transition as quickly as possible. Indeed, we must avoid losing some quality parameters of the tape produced and we want to minimize the time during which the strip length is out of tolerance.
  • the different sections operate continuously in a speed range of 0 to 100 meters per minute and these speeds remain of the same order in all the different sections and in all operating phases. From this done, after a slowdown step, there is no need to very quickly return to normal scrolling speed because the speeds in all sections can be increased gradually, with an average acceleration rate. So we can use lower power motors than in installations classics and thus significantly reduce the investment cost and energy expenditure.
  • a 10% speed increase up to 55 m / min, will allow to fill the accumulator 6 in about two minutes, which is quite made compatible with the unwinding time of a reel which is about 10 minutes for a processing speed of 50 m / min and for a laminating coil having a coiled length of about 500 m.
  • the possibility of making the cut in slow movement avoids a shutdown of the rolling mill which would cause the marking of the rolled product, and finish winding the coil which can be evacuated before the new strip head formed at the cut does not reach the engagement device on the winder 42, for the formation of a new coil.
  • This possibility of using only one also a very significant saving by compared to the classic lines in which two must be used winders with turnouts or a carousel winder, such equipment being much more expensive.
  • a coupled line according to the invention could also be simplified by using a rolling mill 30 normally comprising only two cages 33, 34.
  • the invention therefore made it possible to reduce the investment costs and of operation of the coupled line practically in all sections of it and, thus, to make such an installation profitable for average production capacities.
  • Each diagram indicates, on the ordinate, the thicknesses it is possible at the outlet of the installation for different widths of strip indicated on the abscissa.
  • the rolling mill 30 is equipped with working cylinder having a diameter of the order of 320 mm.
  • the hatched area indicates the area of production of a such installation by thickness and width of product, considering that the incoming product, which is delivered by conventional equipment hot rolling or a thin continuous casting installation, has a thickness of the order of 1.5 mm. With a reduction rate from 50 to 64%, it is possible to produce all thicknesses between 0.5 and 1.5 mm up to a bandwidth of approximately 1100 mm.
  • the thickness range is narrower for widths greater than 1100 mm, the outlet thickness being between 0.7 and 1.1 mm for a maximum width of 1500 mm.
  • the bottom continuous line corresponds to the use of blasted working cylinders which wear out fast enough.
  • Figure 3 illustrates the domain of production possible with such an installation and for an incoming product having a minimum thickness of 1.5 mm.
  • the rolling mill comprising at most three cages, these can be fitted with flatness as support cylinders with controlled deformation, or well-being of type Z-High.
