Definitions

  • the invention concerns a support roll for a rolling mill, such as a plate rolling mill, sheet rolling mill or the like, which consists of a shell and a roll shaft/roll spindle, and a method for producing a support roll of this type.
  • the support roll is cast by composite casting techniques and consists of hard, wear-resistant material in the barrel region and of high-grade tough material with high bending fatigue strength in the neck and core regions. This is followed by mechanical working.—multiple-component roll—
  • the entire roll body must be scrapped when the useful barrel region (constructed to be wear-resistant) becomes worn.
  • multipart support rolls are also known.
  • EP 1 056 553 B1 describes a rolling mill with work rolls and multipart support rolls that consist of a main roll body with several roller bearings installed on it side by side in its longitudinal direction, whose outer rings support a rotatable shell that encompasses the roller bearings.
  • the inner surface of the shell rests with full contact on the outer surfaces of the outer rings of the roller bearings.
  • the outer surface forms the roll barrel of the support roll, and three roller bearings are provided on the length of the main roll body, of which the middle roller bearing is designed as a conical roller bearing.
  • the two outer roller bearings are designed as cylindrical roller bearings, and an eccentric bushing that can be rotated by a motor about the longitudinal axis of the main roll body is installed between each of the two cylindrical roller bearings and the main roll body, such that a self-adjustable tilting segment that allows skewing of the cylindrical roller bearing is provided in the load region of the main roll body between the main roll body and each eccentric bushing.
  • German Early Disclosure 1 602 121 describes a multipart support roll for four-high rolling stands for rolling out flat metal products, in which the rolling forces to be absorbed by the support roll are transmitted from the cylindrical surface of the support roll to the spindle or shaft in only two places within the width range of the roll barrel.
  • EP 0 896 841 A2 discloses a rolling mill with work rolls and multipart support rolls that consist of a main roll body with several roller bearings installed on it side by side in its longitudinal direction, whose outer rings support a rotatable shell that encompasses the roller bearings.
  • the outer surface forms the roll barrel of the support roll, where the main roll body can rotate about its longitudinal axis and is divided into cylindrical sections that have approximately the same width as the roller bearings.
  • the parallel axes of these adjacent cylindrical sections are offset relative to each other.
  • the inner surface of the shell rests with full contact on the outer surfaces of the outer rings of the roller bearings and in this way is provided with an eccentricity that results from the eccentricity of the sections of the main roll body, reduced by the opposing bending effect of the shell.
  • DE 197 02 325 A1 discloses a method for producing vibration-damped rolls.
  • this method to change the values of the natural frequencies of at least one roll, at least one cavity that is parallel to the axis is formed in at least one support roll and/or an associated work roll.
  • a set of rolls of the invention which consists of at least a work roll and support roll, at least one roll is provided with at least one cavity that is parallel to the axis.
  • EP 0 937 515 B1 discloses a roll that consists of a rotating roll jacket and means, which are installed inside the roll jacket, for controlling the flexural rigidity of the roll jacket.
  • the control means consist of a sliding bearing in the form of a rotatable body, which can be rotatably adjusted and is shaped in such a way that its load-bearing surface corresponding to the loaded zone of the roll jacket is part of the cylindrical outer surface of a rotationally symmetric body, and the boundary of this cylindrical outer surface is formed in such a way that the width and/or position of the load-bearing surface varies along the circumference of the rotatable body.
  • the rotatable body In the region of its load-bearing surface, the rotatable body has at least one recess. The course of the boundary of this recess and its inner contour can be shaped in any desired way.
  • support rolls are constructed as shell rolls, i.e., an outer sleeve or the like rotates about an inner shaft, spindle or the like.
  • Support rolls with a large total weight that are produced by these previously known methods have the same disadvantages with respect to shipping, etc., as a single-part support roll.
  • the objective of the invention is to simplify production of the known support rolls, shorten the delivery time, increase the service life, and reduce the aforementioned disadvantages, such as high shipping costs.
  • the solution to this problem is characterized by the fact that, in a support roll for a rolling mill, such as a plate rolling mill, sheet rolling mill or the like, which consists of a shell and a roll shaft/roll spindle, the roll shaft/roll spindle is constructed from multiple parts.
  • one or more bores are provided in the half-journals.
  • the half-journals run parallel to the axis and are, for example, symmetrically arranged. If only one bore is provided, the axis of the bore is identical with the longitudinal axis of the half-journal.
  • both half-journals are formed with through bores, into which a tension bar/tie rod is inserted to pretension the two half-journals with respect to each other.
  • one half-journal is provided with through bores, and the other half-journal is provided with threaded bores, into which threaded rods/pretensioning bolts are turned.
  • the half-journals are cylindrically shaped in the region that is surrounded by the shell.
  • this region is designed in the form of a conical frustum.
  • a conical seat is provided, which has a small conical angle and a self-locking design.
  • a bushing is provided between the two half-journals. This bushing makes it possible to produce support rolls of different lengths with the same half-journals. The different lengths of the shells are bridged by one or more adapted bushings.
  • a bushing can be designed with the threaded bore or threaded bores.
  • the half-journals are then designed only with through bores.
  • the invention also concerns a method for producing a support roll that consists of a shell and a multipart roll shaft/roll spindle.
  • the shell is internally heated and thus expands.
  • the half-journals are then inserted into the shell and pushed up against the right and left end walls of the shell.
  • the half-journals have, for example, at least one locating edge on their circumference.
  • the support roll which consists of the shell, right half-journal, and left half-journal, is held together by a shrink fit after the shell has been cooled. A support roll of high flexural rigidity is obtained.
  • the two half-journals and, if necessary, the pretensioning bolt or bolts are removed from the shell. Due to the construction of the support roll in accordance with the invention, the right half-journal, the left half-journal, and the pretensioning bolt or bolts can be reused.
  • FIG. 1 shows a perspective sectional view of a multipart support roll.
  • FIG. 2 shows a perspective sectional view of a support roll of the invention, in which the shell is designed with a journal.
  • FIG. 3 shows a perspective sectional view of a support roll of the invention with barrel or shrink rings.
  • FIG. 4 shows a perspective sectional view of a support roll with a cavity.
  • FIG. 5 shows a perspective sectional view of a two-part embodiment.
  • FIG. 6 shows a sectional front view of a variant of a support roll according to FIG. 4 .
  • FIG. 1 shows a perspective sectional view of a support roll 1 .
  • the support roll 1 consists of a shell 2 and a roll shaft/roll spindle 3 .
  • the roll shaft/roll spindle 3 is formed by a left journal 4 and a right journal 5 .
  • Holding fixtures for bearings are formed at the outer ends.
  • the inside of the shell 2 is designed in the form of a conical frustum, starting at each of the end faces 6 , 7 .
  • the journals 4 , 5 are provided with a stop edge 8 , 9 .
  • the left journal 4 has a threaded bore 10
  • the right journal 5 is provided with a through bore 11 , through which a pretensioning bolt (not shown) is passed.
  • FIG. 2 Another embodiment is shown in FIG. 2 .
  • the left journal 4 is designed in such a way that it is installed in the shell 2 over a great length.
  • the shell 2 is formed at its right end, for example, with a journal 12 , which is cast on or forged on at one end.
  • the left journal 4 and the shell 2 are joined by means of combined conical shrink fit 14 and/or cylindrical shrink fit 15 .
  • This three-part support roll is held together by a pretensioning bolt 13 .
  • the left journal 4 directly receives a journal bearing (not shown).
  • barrel or shrink rings 16 are shrink-fitted over the entire length of the barrel, as shown in FIG. 3 .
  • several equally wide or variably wide barrel or shrink rings 16 are shrink-fitted onto graduated cylindrical diameters of the shell 2 .
  • An advantage of this is the possibility of shrink-fitting new barrel or shrink rings 16 when these have reached the end of their usable diameter after repeated regrinding. The shell 2 can be used again.
  • the support roll 1 consists of the shell 2 and the journals 4 , 5 , which are inserted only a short distance into the shell 2 . This results in the formation of a cavity 17 in the shell 2 .
  • the journals 4 , 5 are, for example, pressed in by means of an easy cylindrical or conical fit in the shell 2 .
  • the journals 4 , 5 are bolted with the shell at both ends by a sufficient number of bolts 18 .
  • the advantage of this embodiment is the possibility of reusing the left journal 4 and the right journal 5 when the outside diameter of the shell has been ground down to the point that it has reached the end of its predetermined usable diameter.
  • the equipment for changing the support roll 1 can be designed with smaller dimensions, because the whole support roll 1 is lighter than a solid roll.
  • a multipart roll shaft/roll spindle 3 in a support roll 1 is realized by forming the left journal 4 as a single part with the shell 2 .
  • the right journal 5 has a stop face 19 to allow proper positioning of the two parts.
  • the two parts are joined after the cylindrical shell has first been heated. After insertion of the journal 5 , followed by cooling, a strong joint is present in the form of a transverse press fit. Due to the action of friction, sufficient fixation of the axial position is guaranteed.
  • the connection is additionally secured, as described above, by means of a pretensioning bolt or several pretensioning bolts. The use of a pretensioning bolt or bolts is helpful during the assembly of the support roll.
  • FIG. 6 shows a possible variant of the embodiment of a support roll shown in FIG. 4 .
  • the shell 2 consists of a cast hollow body or a hollow body that is forged over a mandrel.
  • the ends of the shell are already formed as a single part with regions for holding bearings.
  • the actual journals of the roll shaft/roll spindle 3 (not shown) are again secured by means of bolts and/or a joint seat.
  • the advantage of this embodiment is that the weight of the support roll is reduced.
