Definitions
- the invention relates to a method and a roll stand for rolling sheets or strips, with work rolls, which are supported on support rolls or intermediate rolls with support rollers, wherein the adjustment of the roll gap profile is carried out by axially displacing provided with curved contours roller pairs.
- the rolls of selected pairs of rolls are in pairs axially displaceable against each other and each roll of such a pair of rolls is provided with a curved contour which extends on both rolls of the roll pair to opposite sides over the entire length of the roll barrel.
- Known embodiments are quarto scaffolding, six-high rolling stands and the various forms of multi-roll stands arranged as one-way stands, reversing stands or tandem rolling stands.
- Roll stands with effective adjusting mechanisms for the presetting of the required roll gap and for the change of the roll gap under load are in the EP 0 049 798 B1 described and are therefore already prior art. Used here are work rolls and / or back-up rolls and / or intermediate rolls, which are axially displaceable against each other.
- the rollers are provided with a curved contour extending towards a bale end, which extends on the two rollers of a pair of rollers respectively to opposite sides over the entire length of the bale rolls and which has a shape in which the two bale contours are exclusively in a certain relative Complement complementary axial position of the rollers.
- the feature of complementary complementation in a particular axial position determines all point-symmetric functions to the nip center as appropriate.
- the 3rd degree polynomial has been found. So is out of the EP 0543 014 B1 a six-high rolling stand with axially displaceable intermediate and work rolls, in which the intermediate rolls have crowns which are point-symmetrical with respect to the framework center point and whose crowning can be expressed by a third-degree equation.
- This function of the roll contours, which is point-symmetrical with regard to the nip center manifests itself in the load-free nip as a polynomial of the second degree, ie as a parabola.
- Such a nip has the particular advantage that it is suitable for rolling different Walzgutbreiten.
- the achievable by the roller displacement change in the profile height allows a targeted Adaptation to the influencing variables described above and already covers most of the required profile setting with high flexibility.
- the object of the present invention is to solve the above-exemplified problem with a simple mechanism and to achieve a further improvement of the adjusting mechanisms and the strategy for producing absolutely flat sheets or strips with a predetermined thickness profile over the entire width of the rolled rolled material.
- the object is achieved with the characterizing features of claim 1, characterized in that the setting of the roll gap is performed by at least two independently axially displaceable roller pairs with different curved contours whose different contours by splitting the effective in the nip gap setpoint profile in at least two different Roll nip nominal profiles are calculated and transferred to the roller pairs.
- a roll stand for rolling sheets or strips is characterized by the features of claim 6 and the features of further subclaims.
- the function of the unloaded roll gap required for setting the roll gap profile is first developed for two selected shift positions as polynomial of the nth degree with even exponents.
- each of these two functions to be used for a pair of rollers is split into a second-order polynomial with the known positive properties for presetting and a residual polynomial with higher even powers, which yields profile 0 in roll center (the profile height in FIG Roller center is identical to the profile height at the edges) and has two maxima on both sides of the roller center, which are suitable for influencing quarter-wave.
- the function of the roll gap is thus revealed as the difference between the axial spacing of the rolls and twice the sum of even powers, that is to say as a function symmetrical to the middle of the framework. Obviously, this result is achieved without specifying a specific radius function and therefore applies to every differentiable function.
- the chosen radius function determines only the coefficients of the power elements via its derivatives.
- Equation (G7) describes the roller profile with which the ideal roller is to be equipped in a certain displacement position.
- the polynomial must be split into individual polynomials, each of which can be dimensioned with a value that can be understood for operational practice.
- R ⁇ i 2 - q 0 ⁇ z 0 + c 2 ⁇ z 2 + q 2 ⁇ z 2 for the share Second degree
- R ⁇ i 4 - q 2 ⁇ z 2 + c 4 ⁇ z 4 + q 4 ⁇ z 4 for the share 4th degree
- R ⁇ i 6 - q 4 ⁇ z 4 + c 6 ⁇ z 6 + q 6 ⁇ z 6 for the share 6th degree
- the value q 6 is 0 for the highest 6th degree considered here, since it is assigned to the nonexistent 8th degree. It is therefore also necessary numerically to start the resolution with the highest degree.
- Ri 0 of equation (G9) is freely selectable as nominal radius of the roller.
- two displacement positions s 1 and s 2 are to be selected, for each of which the desired profile is to be determined by selecting the crown values of Cr 2 to Cr n .
- the profiles will change continuously due to the roll displacement. Since the individual power levels can be dimensioned independently of one another, eliminating the mandatory requirement of a complementary complement of the roll profiles of upper roll to lower roll. However, this can easily be brought about by deliberately setting the profile height 0 for one of the two freely selectable displacement positions, if necessary also outside the real displacement path, uniformly for all degrees of power.
- Equation (G7) consists, as already described above, for two shift positions s 1 and s 2 . Equating the two equations (G7) with Eq. (G6) yields the determinative equations necessary for the coefficients a i of the polynomial for the roll grinding, corresponding to the selected power level. The individual equations of equations are from the coefficient scheme of FIG. 2 immediately readable.
- the coefficient a 1 remains indefinite because it has no influence on the profile shape of the roller. It determines the taper of the roller and therefore requires a different design criterion, which will be explained below on contact of a profiled roller with a cylindrically shaped intermediate roller or back-up roller.
- the raised profile areas of the profiled roller will embed in the contact area by elastic deformation in the cylindrical roller and possibly bring about a non-parallel position of the two rollers to each other.
- the pitch a 1 of the work roll contour must be dimensioned such that the center lines of the two rolls are parallel to one another.
- a rolling line forms in the contact zone, which is also parallel to the center lines of both rolls.
- the radius of this rolling line with respect to the work roll is R w .
- the force element dF generated over the distance z a moment element dM K , which causes a tilting of the rollers.
- the length-related spring constant may be set as constant over the contact length.
- Equation (G25) is also valid for profiled rolls which are in contact with the profiled roll of another roll pair, if the coefficient a 1 of this contact roll has also been dimensioned by equation (G25).
- the at least two pairs of rollers will be chosen differently depending on the framework construction.
- z. B the slidable intermediate rolls provided with a profile which generates the polynomial 2nd degree in the nip.
- the movable work rolls are suitable for the remaining polynomial and serve to influence the quarter waves or other special profile influencing.
- the profile heights of the profiles to be set by the respective pair of rollers will be increased in a manner known per se in order to improve penetration through the nip, in particular with pairs of rollers located further from the nip.
- the two maxima in the residual polynomial are in a position symmetrical to the roll center, which is variable over the degree of the polynomial. This results in - depending on the framework construction - the possibility to create a further adjustment for eighth-waves or edge waves on another sliding pair of rollers. Of course it is also possible to introduce this variant in the simplest way on the roll change.
- FIGS. 3 to 5 the possible displacement ranges of individual displaceable roller pairs (P1, P2, P3) with differently curved contours are shown on exemplarily selected rolling stands (1, 1 ', 1 ")
- Fig. 3 is shown in a side view a quartz scaffolding 1. It consists of a displaceable pair of rollers P1, the work rolls 2, and a further displaceable pair of rollers P2, the support rollers 4. Between the work rolls 2, the rolling stock 5 is rolled in the nip 6.
- FIGS. 3a and 3b in which the quarto scaffolding 1 of the FIG. 3 is shown rotated by 90 °, the possible displacement ranges of the roller pairs P1 and P2 pointed out.
- respective displacement paths of the roll centers 7 are possible by the amount sp1 for the pair of rolls P1 and sp2 for the pair of rolls P2 to the right or to the left.
- the shifts are limited by the reference width bo, when a roll edge is shifted in the vicinity of the rolling stock edge of a rolling stock width corresponding to the reference width.
- FIG. 4 is a side view of a 6-roll stand 1 'shown. It consists of a displaceable pair of rollers P1, the work rolls 2 and a displaceable pair of rollers P2, the intermediate rollers 3 and a further, non-displaceable pair of rollers, the support rollers 4th
- FIGS. 4a and 4b in which the 6-roll stand 1 'of Fig. 4 is shown rotated by 90 °, the possible displacement ranges of the roller pairs P1 and P2 are shown. The shift takes place here in the same way as in the FIGS.
- FIG. 5 is a side view, as an example of a multi-roll stand, a 10-roll stand 1 "is shown. It consists of a displaceable pair of rollers P1, the work rolls 2, a displaceable pair of rollers P2, the intermediate rolls 3 ', a further displaceable pair of rollers P3, the intermediate rollers 3 "and the two support roller pairs 4' and 4".
- FIGS. 5a and 5b in which the 10-Walzengerüst 1 "the Fig. 5 is shown rotated by 90 °, are in a section through the rollers 4'-3'-2-2-3'4 'the possible displacement ranges of the roller pair P1, the work rolls 2 and the roller pair P2, in the Fig. 5 shown intermediate rolls 3 'shown.
- the maximum displacement is sp1 or sp2.
- FIGS. 5c and 5d point in a section through the rollers 4 "-3" -2-2-3 “-4" again the pair of rollers P1, but this time together with the pair of rollers P3, ie with the in the Fig. 5 arranged on the right intermediate rolls 3 "with the maximum displacement sp3.
- the displacement paths of all three roller pairs are independent of each other within the maximum values sp1, sp2 and sp3 in direction and magnitude.
- the two pairs of support rollers 4 'and 4 are also formed immovable in this embodiment of the 10-roll stand 1".
- the 10-roll stand 1 is thus clear, with which variety of different combinations with a correspondingly large number of sliding pairs of rollers with different curved roll contours, the paired roll displacement and thus a sensitive influence of the roll gap 6 can be performed.
- FIGS. 6 and 7 are in an inventive form of representation, the predetermined roll gap profiles for the two selected shift positions of a pair of rollers of the prior art in the shares of a polynomial 2nd degree and a residual polynomial 4th degree separated.
- FIGS. 10 to 17 is shown as the in the FIGS. 6 to 9 selected roll gap contours with polynomials 2nd and 4th degree according to the invention can be transmitted to two independently displaceable pairs of rollers.
- FIGS. 14 and 15 the selected nip nominal profiles 22 and 23 of the FIGS. 6 and 7 known polynomial 4th degree. They lead to the in the FIGS. 16 and 17 illustrated roller contours of the upper roller 32 and the lower roller 32 'and are also continuously variable within the displacement range.
- roller pair P1, P2, P3, which has the profile of a 4th degree polynomial, it is thus possible to sensitively influence the so-called quarter waves from +50 ⁇ m to 0 to -50 ⁇ m, without the adjustment of the set of rolls for the 2nd. Degree of adverse change is subject.
- a nearly parallel nominal roll gap profile 25 is required, which is intended to open only at the rolling stock edges. It is formed by the addition of the function curves 24 of polynomials with the degrees 2, 4, 6, 8, 10, 12, 14 and 16 with the profile heights 400, 100, 60, 43, 30, 20, 14, and 10 microns.
- FIGS. 20 and 21 the corresponding roller contours 33 for the upper roller and 33 'for the lower roller are shown. It can be seen that the desired opening of the roll gap by the drop of the nominal roll gap profile 25 ( Fig. 20 ) at the edges of the rolling stock, which is displaced in the direction of -100 mm ( Fig. 21 ) reduced to 0. At -100 mm there is a parallel nip with a slight s-shaped curvature at the rolling stock edges.
- a roller pair designed in this way allows the sensitive correction of the thickness decrease at the rolling stock edges. According to the invention, such a pair of rollers can be used advantageously in conjunction with a pair of rollers for the parabolic contour corresponding to FIGS. 10 to 13 be used. Also, with appropriate scaffolding design, the additional inclusion of a correction option with rollers according to the FIGS. 14 to 17 conceivable.
- each movable roller pair P1, P2, P3 are described by two freely selectable symmetrical profiles arbitrarily high degree, which are also assigned two freely selectable shift positions.
- the profile heights of the individual degrees of power for the two freely selectable displacement positions are different when choosing a profile shape from more than one power degree. This has the consequence that the displacement position to achieve the profile height 0 for the different degrees of power is different, so that a complementary complement of the roll contours is deliberately avoided.
- the profile height of all powers is set to 0, to complement each other To force roller contours in this displacement position.
- the selected displacement position for the profile 0 can also be outside the real displacement range.
- the profile heights of the individual degrees of power for the two freely selectable displacement positions are chosen such that the distance between the two profile maxima of a minimum by the roller displacement continuously changed to a maximum.
- the invention is not limited to the use of polynomials.
- the transcendental functions or exponential functions are mathematically resolved into power series.
- the operational application or the actual displacement of the individual pairs of rollers takes place in a known manner in that the displacement systems of the roller pairs P1, P2, P3 are used as adjusting systems in a closed flatness control loop.
- the current flatness of the rolling stock is determined and compared with a target value.
- the deviations across the bandwidth are analyzed according to degrees of power and assigned to the individual roller pairs P1, P2, P3 as manipulated variables in accordance with the degrees of power that can be influenced by them.
- Example shown would assign to the pair of rollers for generating the nominal nip profiles 20, 21 control values for the elimination of center shafts and the pair of rollers for generating the desired nip profiles 22, 23 control values for the removal of quarter waves.
- the direct measurement measurement in the form of a measurement of the thickness distribution over the rolling stock width takes the place of the flatness measurement in the control loop by measuring the tensile stress distribution.
