Definitions

  • the invention relates to a roll arrangement for rolling angle profiles of rolling stock, comprising an upper horizontally arranged caliber roll and a lower horizontally arranged caliber roll, which together define a rolling gap with open caliber, which lies in a roll plane perpendicular to the conveyance of the rolling stock and at least a few not horizontally arranged edging rolls, which compress the rolling stock laterally and define a rolling plane which is perpendicular to the conveying direction of the rolling stock.
  • Such angle profiles are, for example, angles with identical or unequal legs and the like.
  • the DE 36 277 729 C2 to take a mild steel rolling mill, in the (universal) rolling stands, if necessary, in reversing rolling operation be used to form a desired profile cross-section.
  • a disadvantage of this variant is that with such a rolling variant, the edger scaffold, which is usually designed as a simple duo scaffolding, must be designed as a comparatively cost-intensive universal scaffold.
  • Another major disadvantage of this universal rolling method is that the large non-driven vertical rolls must be driven by the horizontal rolls of the edger. For this reason, a web removal must also be rolled in the edger frame, resulting in thickened ends of the profile produced in the vertical roll nips. These thickenings in turn are additionally reinforced by the required Absex at small leg strengths and the associated expansion of the rolling stock.
  • such a form of the universal rolling process does not allow predefined radii to be defined and controlled at the leg tips of the angle legs.
  • the invention provides a modified roll arrangement for rolling angle profiles made of rolled stock, in particular of steel, in which the rolling plane defined by the at least one pair of caliber rolls with open or closed caliber does not coincide with a rolling plane defined by at least one pair of edging rolls is. Rather, the upsetting rolls are arranged in pairs in the rolling direction before and / or behind the nip defined by the caliber rolls.
  • This rolling stand according to the invention can effect the angular rolling both in reversing and continuous driving.
  • the invention allows the rolling of both natural edged and round-edged leg tip radii embodiments with the inventively modified roller assemblies. Isosceles and unequal legs with the same or different thigh thicknesses and natural edged or defined round-edged leg tips can be rolled by the inventive modification of the roll arrangement in open or closed calibration, but with the essential standard scaffold arrangements of reversing, semi-continuous or fully continuous rolling mills. As natural edged, such contours are understood to be the result of a free expansion in the forming without specifically influencing the contour geometry.
  • the punctures required for the respective angle size to be produced for the angular calibration with open or closed caliber are rolled out of geometrically sufficiently sized cross-section in the preliminary stitches in the usual known form.
  • These cross-sectional shapes referred to as guide stitches, are preferably geometrically matched in shape to the subsequent calibers, although methods are also preferred are, in which the calibers are geometrically matched to the predetermined by the Leitstiche cross-sectional shape.
  • the compression rollers are arranged in pairs behind the caliber rollers, so that the roller plane defined by the at least one pair of compression rollers lies behind the roller plane of the caliber rollers in the conveying direction of the rolling stock.
  • the compression rollers are arranged in pairs in front of the caliber rollers, so that the roller plane defined by the at least one pair of compression rollers lies in the conveying direction of the rolling stock in front of the roller plane of the caliber rollers.
  • the roller assembly according to the invention can also be used in continuous rolling operation, with no restrictions on the system technology. If, for example, a roller arrangement with compression rollers arranged in front of and behind the caliber rollers is used in continuous operation If necessary, if necessary, the upset before the caliber rolls upsetting roller pair can be exposed individually from the angular edge region and thus exert no influence on the rolling result. The same applies analogously, of course, also for the compression roller pair arranged in the rolling direction behind the caliber rollers.
  • the roll arrangement according to the invention is arranged on a common scaffold foundation and therefore also used as a quasi-modified universal rolling stand within a rolling mill.
  • a framework comprehensive conversion or replacement or the exchange of complete sets of rollers can be supported.
  • the rolled width can thus be smaller than the horizontal bale width, as a result of which the major disadvantage of the universal caliber rolling known from the prior art with conventional H and V roll arrangement in one and one nip between the V-rolls and the end faces of the H-roll. Rolling is avoided.
  • this angle with different leg length can be rolled with the same set of rolls, which is particularly advantageous is supported if the compression rollers can be made individually and also within the respective pairs of compression rollers to the rolling stock.
  • the H-rolls of the scaffolds have similarly designed open draw calibers for reducing the thickness to the desired finish angle thickness. It is typical here that in all stands the bale widths are chosen to be so large that even the longest, length-specific leg lengths associated with a dimensioning group are reshaped in the ball area of the H-rolls.
  • the compression rollers need not be arranged vertically and perpendicular to the caliber rollers. Rather, embodiments are considered to be encompassed by the inventive concept, in which the upsetting rollers have only an inclined position of their longitudinal axes to the longitudinal axis of the upper or lower caliber roller, which in principle a V-shape of the position of the pair or pairs of compression rollers is effected to each other.
  • the advantage of an inclined position of the longitudinal axes of the compression rollers is a lower leg deflection in the finish stitch. This is particularly advantageous for angles with long leg length.
  • the possibility of producing a large variety of profiles is supported by the ability of the roller assembly according to the invention to an inclined setting of the compression rollers with respect to the rolling stock without the need to replace entire plant parts.
  • Preference is given to influencing the mean stretched profile width and thus the leg lengths on the vertical, but at least inclined arranged upset rollers.
  • the width-dependent dimension groups are predominantly determined by the possible vertical adjustment range of the roller arrangement, preferably in a modified universal rolling stand, since the compression rollers are not hindered by the H-bale width.
  • the shape of the compression rollers of a roller arrangement according to the invention is not necessarily strictly cylindrical with a round cross section, but may deviate from this shape at least over part lengths of the compression rollers.
  • the vertical compression rollers are executed depending on the used horizontal caliber form of Kaliberwalzen cylindrical or conically smooth when the leg ends of the angle profile to be produced are natural edge or undefined desired in the edge radius.
  • the vertically arranged compression rollers can also be discontinued and executed with a defined transition radius in the heel corner.
  • the offset rollers with transition radius are, however, preferably also used for horizontal caliber forms of Kaliberwalzen with horizontal and parallel position of the leg angle profile to the longitudinal axis of the respective Kaliberwalzen.
  • each roller arrangement according to the invention arranged in pairs before and / or behind the horizontally arranged caliber rollers, the use of the roller assembly according to the invention results in a very effective influencing the stretched profile width of the angle profile, although for small compression rollers the maximum vertical rolling force to the usual Vertical rolls can be significantly undercut with large roll diameter and large bale width.
  • the necessary width reduction is preferably distributed over twice the number of stitches in comparison to the conventional, known universal angle-rolling method.
  • the arrangement of the compression rollers in front of and / or behind the horizontal caliber rollers also makes it possible to immediately neutralize the widths caused by a thigh thickness reduction.
  • the roller arrangement according to the invention is part of a rolling train which comprises at least one rolling stand with a roller arrangement according to the invention and at least one finished caliber.
  • the roll arrangement according to the invention can also be part of a compact or tandem group which has at least one roll arrangement according to the invention and a finished caliber and a pair of compression rolls arranged between the roll arrangement and the finished caliber.
  • the finished compact group has two roll arrangements according to the invention and a pair of compression rolls arranged between these two roll arrangements.
  • the horizontal work roll calipers on the universal stands and the swaging stand are usually made the same.
  • the second universal scaffolding must be used as a duo scaffolding to accommodate the finished caliber.
  • the edger with horizontally arranged edger rolls, so-called "Edger”
  • the finished caliber on the edger can be arranged and the second stand with the roller arrangement according to the invention for an effective Vorwalzung be shared.
  • this additional arrangement of the finished caliber on the bale of the edger stand also allows a two-stand rolling mill group with a roll arrangement according to the invention and a edger (edger) for this type of Winkelwalzung can be used.
  • the stretch caliber in the first and second stand of the compact group can also be selected differently in the acute angle geometry.
  • the constant folding process is then preferably complete or partially done in the edger.
  • a preparatory folding in the 90 ° position can then be prepared preferably with the use of a displaceable stuffer with horizontally arranged edger rollers (Edger) with sufficient bale length in a second caliber on the edger stand itself.
  • the second roll stand with the roll arrangement according to the invention is then run through empty from the rolled section and the folding process is prepared in Vorkaliber on the stuffer and completed on the separate finishing stand.
  • Advantages of this special solution are, in particular, a low caliber wear in the finished caliber and a flatter design of the inventively modified mill stands with open or closed caliber, which overall enables better roll utilization.
  • the invention is realized by using a roll arrangement comprising an upper horizontally arranged caliber roll and a lower horizontally arranged caliber roll, which together define a nip with open or closed calibers perpendicular to a roll plane Conveying direction of the rolling stock, as well as at least a pair of non-horizontally arranged edging rolls, which compress the rolling stock laterally and define a rolling plane which is perpendicular to the conveying direction of the rolling stock, wherein the defined by the at least one pair of Kaliberwalzen roller plane and defined by a pair of edging rolls roller level are not congruent.
  • the rolling stock is formed before and / or after the rolling pass through the horizontally arranged caliber rolls by at least one pair of non-horizontally arranged edging rolls.
  • FIG. 1 a roll arrangement 1 according to the invention is shown, in which an upper, horizontally arranged caliber roll 2 and a lower, horizontally arranged caliber roll 3 define a roll gap and a roll plane which is perpendicular to the direction of travel (indicated by the arrow> travel ⁇ ) of the rolling stock 6 ,
  • the roller assembly 1 shown here arranged in a common frame, is used as a reversing rolling stand, through which the rolling stock 6 both in the drawing from left to right and from right to left by the upper caliber roller 2 and the lower Caliber roller 3 defined rolling plane passes through.
  • left to the rolling plane defined by the caliber rolls 2 and 3 a pair of left upset rolls 4 are arranged, of which only the front upset roll is shown in the figure.
  • each upsetting roller pairs 4a, 4b and 5a, 5b are shown, wherein the compression roller pairs 4a, 4b have a smooth, cylindrical calibration with a vertical arrangement of its longitudinal axis to the angle section 6.
  • angle leg 9, 10 are generated, which are parallel and aligned with each other and an angle tip 8 on top of the Angle profile 6 and an angle radius 11 are connected to each other at the lower side of the angle section 6.
  • the longitudinal axis as well as the upsetting rollers 4a, 4b are arranged vertically in the left view.
