Definitions
- Roll stand for the production of rolled strip or sheet metal
- the invention relates to a rolling stand for the production of rolled strip or sheet metal with work rolls, which are supported on support rolls or intermediate rolls and backup rolls, wherein at least one of these rollers has a running over the entire effective bale length, describable by a non-linear function bale contour and the bale contour of this at least one Roller has bevels in at least one of the edge regions of their longitudinal extent and forms a corrected bale contours in these edge regions.
- a rolling stand of this type is already known, for example, from AT 410765 B.
- the roll bale contour of these rollers known in the art under the name SmartCrown® is mathematically describable by a modified sine function. By a suitable choice of the contour parameters, this results in a cosinusoidal idling gap, which can be influenced in its amplitude by axial displacement of the rollers.
- the rolls of rolling mills can also have many other bale contours, which are characterized, for example, by a cylindrical, bulbous, concave-convexly curved or another curved contour.
- WO 02/09896 A1 and WO 2005/058517 A1 disclose a two-stage regrind of the bale contour on work rolls in a quarto scaffolding or on intermediate rolls on a sexto scaffold. Starting from the central bale contour in the direction of the bale end, a first regression using a circular arc function, wherein in the transition region of the central bale contour in the regrind contour exactly the same problems occur, as previously described with respect to the older prior art. The first regrind is followed by a second regrind, which extends to the end of the bale and realizes a cylindrical bale contour.
- the object of the present invention is therefore to avoid the above-described disadvantages of the prior art and to propose a rolling stand in which inhomogeneities in the load distribution along the contact line of the support rollers and their Minimize adjacent rollers and in particular local load peaks in the load distribution curve, especially in the edge area, reduce and thus increase the service life of the rollers and the necessary regrinding intervals.
- the corrected bale contour is obtained by subtracting any nonlinear mathematical chamfering function from the contour function described by the nonlinear function, wherein the slope of the bale contour and the slope of the corrected bale contour in the transition point of the Bale contour to the corrected bale contour are the same.
- an exemption is achieved at the opposing bale contours of adjacent rollers along a defined chamfering length.
- the back-up rolls in a quarto scaffold and the back-up rolls or the intermediate rolls in a sexto-scaffolding are equipped with a corrected bale contour.
- FIG. 1 is a schematic representation of a four-high stand with contoured work rolls and cylindrical support rolls according to the prior art
- FIG. 2 shows the typical load distribution between work rolls and support rolls in a four-high stand according to FIG. 1, FIG.
- Fig. 3 is a schematic representation of a four-high stand with contoured work rolls and complementary support rollers. 4 shows the typical load distribution between work rolls and support rolls in a four-high stand with the roll formation according to FIG. 3, FIG.
- FIG. 5 is a schematic representation of a six-high stand with contoured backup rolls and complementary intermediate rolls according to the invention
- FIG. 6 is a schematic representation of a four-high stand with contoured work rolls and complementary back-up rolls according to the invention, in which the bale contours are no longer completely complementary
- FIG. 7 shows the contour according to the invention of the upper support roller taking into account a circular chamfering function in comparison with bale contours according to the prior art
- FIG. 10 shows the representation of a possible chamfering function according to the invention.
- FIGS. 1 to 4 the load distribution between back-up rolls and work rolls in a roll bale contour according to the prior art is compared with the load distribution between back-up rolls and work rolls in a roll bale contour according to the invention using the example of a four-high stand.
- FIG. 1 shows a schematic representation of the roll arrangement in a four-high stand for rolling a metal strip B, in particular a steel strip with work rolls 1 and back-up rolls 2.
- the axially displaceable work rolls 1 each have a bale contour 3 which can be described by a concave-convex function.
- the work rolls 1 are supported by support rollers 2, which have a cylindrical bale contour 4 and are supported on the work rolls acting rolling forces.
- the load distribution between the upper work roll 1 and the upper support roll 2 is shown in this case of the roll bale design in Figure 2, wherein the specific force between the rolls is applied over the bale length and on the one hand Stress peaks in the edge region emerge and on the other hand maximum and minimum values corresponding to the convex-concave contour curve occur.
- load distribution curves are illustrated which are already based on a chamfering function according to the prior art.
- FIG. 3 shows a schematic representation of the roll arrangement in a four-high stand with work rolls 1 and back-up rolls 2.
- the axially displaceable work rolls 1 in turn each have a describable by a non-linear function bale contour 3, said bale contours in a certain relative axial position of the work rolls complementarily complement.
- the two support rollers 2 also have a complementary complementary bale contour 4, which is also formed by a non-linear function, with the bale contours of the adjacent, cooperating work roll 1 and support roller 2 completely complement each other in an unloaded state.
- the load distribution between the upper work roll 1 and the upper support roll 2 is shown in FIG.
- FIG. 5 shows, in a schematic arrangement, the roller arrangement in a six-high stand with work rolls 1, intermediate rolls 5 and support rolls 2, the work rolls being supported on the support rolls via the intermediate rolls.
- the work rolls 1 are equipped with a cylindrical bale contour 3.
- the bale contour of the work rolls can also be oriented to the bale contour of the adjacent intermediate rolls.
- the intermediate rollers 5 have a bale contour 6 that can be described by a non-linear function.
- the support rollers 2 have a bale contour 4 that can be described by a sine function.
- the bale contours 4 of the support rollers 2 and the bale contour of the intermediate rollers 5 complement each other completely in the unshifted axial position of the axially adjustable intermediate rollers 5 in the unloaded state.
- FIG. 6 shows work rolls 1 and support rolls 2 in a four-high stand in a schematic representation
- the basic construction of the bale contours 3, 4 of FIGS Embodiment of Figure 3 follows. However, the contour is changed, whereby in the unloaded state only a partial or no supplement of the bale contours of the support roller 2 and the immediately adjacent work roll 1 occurs.
- bale contours can also be chosen so that the contoured rolls have a positive or negative crown.
- FIG. 7 shows the course of the roll bale contour 7 of a back-up roll or intermediate roll or work roll over the length of the bale.
- dash-dotted lines 8, 9 known from the prior art possibilities of chamfering a roller in the end regions are shown to avoid high edge pressures.
- the chamfering according to the dotted line 8 produces a cylindrical end portion and the chamfering corresponding to the dotted line 9 a cone-shaped end portion of the rollers, in both cases a kink 10 in the contour over the bale length occurs, which forms a circumferential edge on the roller.
- An improvement in the loading conditions results from a chamfer gradually approaching the bale contour, whereby on both sides a corrected bale contour is formed, which is illustrated by the dotted lines 11 and 12.
- both curves have the same slope as the tangent t.
- FIG. 8 shows, for example, the spherical profile of the roller bale contour 7 described by a nonlinear function on a support roller in a quartz scaffolding or on an intermediate roller or a support roller in a sexto scaffolding.
- the course of the corrected bale contour 11, 12 is illustrated by dotted lines.
- FIG. 9 shows the analogous conditions in a roll bale contour which forms a negative roll crown on the roll.
- FIG. 10 shows the course of the chamfering function 13 using the example of a circular function.
- the amount AR to be subtracted can be expressed by the formula
- a c represents the chamfer amplitude relative to the roller radius.
