Definitions

  • the invention relates to a method for rolling a rolling stock produced in a block casting process, a so-called slab or ingot in a rolling train, wherein the rolling stock before rolling in the form of a truncated pyramid having a base, a top surface and four side surfaces.
  • the invention further relates to a rolling train for rolling such a rolling stock, a control and / or regulating device for such a rolling train, a machine-readable program code for such a control and / or regulating device and a storage medium for such a machine-readable program code.
  • a rolling stock is then produced, for example, in a block casting process and is called "slab" before the rolling process.
  • the slab forms a sheet or strip, ideally having a cuboid shape.
  • a mold is used, which is slightly conical, with its cross-section tapers down. Due to the special shape of the mold, the slab dissolves completely after solidification of the mold wall when the slab is pressed out by means of special pliers from the mold. Without the conicity or convergence of the mold, the slab could not be removed from the mold. However, the slab takes on the shape of the mold, and then there is a problem that the double taper of the slab, ie, a thickness wedge and a wedge of the slab during rolling must be removed.
  • a major problem in the rolling of slabs is to achieve a rectangular basic shape with a constant over the length of the sheet or the strip width.
  • vertically oriented upset rolls are used which can thicken the hot strip in a longitudinal edge region and thus reduce the width of the strip within a certain range.
  • the DE 196 13 718 C1 and the DE 197 57 486 A1 each discloses a plant for the production of hot strip, wherein before a first horizontal rolling mill, a vertical rolling stand is provided, with which the two longitudinal edge regions of a cast semi-finished product is compressed. As a result, a decrease in width of the slab is limited.
  • the invention has for its object to enable a novel processing of a truncated pyramidal slab to a sheet or strip with a rectangular basic shape as uniform as possible width and thickness, in which the use of vertical rolling stands is not provided.
  • roller is here both the slab or the ingot before rolling, as well as their intermediate forms and final shape, which they assume during or after rolling, called.
  • a “rolling pass sequence” is understood to mean a series of rolling passes without rotation of the rolling stock.
  • the rolling stock or the slab which was produced in a mold during ingot casting, due to the geometry of the mold, a thickness wedge and a wedge on.
  • the slab thus has the shape of a truncated pyramid with a base, a top surface that is smaller than the base, and four lateral surfaces forming a lateral surface.
  • the slab lies with a side surface in a horizontal support plane. This "down” oriented side surface, as well as the opposite side surface, which is directed “up” come in rolling pass in contact with the work rolls of the rolling stands of the rolling mill, when the rolling stands are horizontal rolling stands.
  • the slab is characterized by a length, the length of the slab being defined by the distance between the base and the top surface. A width of the slab runs in the support plane transverse to the length. And a thickness of the slab extends substantially perpendicular to the support plane.
  • the slab is usually with its top surface forward in a nip between the work rolls of the rolling stands driven into it, alternatively, however, it can also be moved laterally, ie with one of the side surfaces forward in the nip, this being dependent on the size of the slab.
  • the rotation of the rolling stock by 90 ° takes place in the support plane, ie the side surface with which the rolling stock is located in the support plane remains after rotation in the support plane and it changes only the orientation of the base, the top surface and the other two side surfaces opposite the nip.
  • the invention is based on the idea of enabling a favorable material distribution in a two-stage or multi-stage rolling process, by means of which the desired cuboid shape is achieved in a simple manner.
  • This optimal distribution of material takes place in that all cross-sectional areas of the rolling stock between the base area and the top area have the same area at the end of the first rolling pass sequence in the rolling direction.
  • the wedge-shaped course of the rolling stock in the first direction is in particular inverted.
  • inverting the direction of the converging profile is changed after rolling, so that instead of a diverging course. In other words, a thickening of the slab is replaced by a taper in the rolling direction.
  • the base surface, the top surface and all cross-sectional areas between the base surface and the top surface have the same surface area, ie the product of width and thickness is always the same in the rolling direction.
  • the resulting from the inversion of the wedge-shaped course of the two opposite side surfaces redistribution of the material of the rolling combined with the rolling of the rolling in two transverse directions allows fully automatic, high-precision adjustment of the desired geometry by means of a rolling mill, in the use of vertical rolling stands is not required.
  • an activation of the rolling train is also conceivable, in which the original surface gradient in the rolling direction is not completely reduced or overcompensated.
  • the rolling pass sequence can be carried out on a plurality of rolling stands, wherein a rolling stand is provided in particular for each stitch.
  • the rolling pass sequence can also be performed on a few or even only one stand in a reversible operation in which the rolling direction changes alternately.
  • the rolling process starts in the longitudinal direction of the rolling stock and the first rolling pass sequence, which is also referred to as a pre-sequence, serves to reduce the original thickness difference in the longitudinal direction of the rolling stock and instead to produce a new Dickengradient, but in the opposite direction to the first Dickengradient.
  • the length of the rolling stock is particularly increased.
  • the rolling stock is transported "normally". However, if the odd-numbered rollers are rotated in opposition to the even-numbered ones, the rolling stock rotates around the normal vector standing on the roller table plane.
  • the rolling stock is rolled with the aid of at least one rolling stand, which is set in such a way that the two opposite side faces of the rolling stock are rolled in the rolling direction over their entire length from the work rolls of the rolling stand during each rolling pass.
  • the height of the roll gap in which the dimension or height of the roll gap is actively adjusted during de Walzstiches.
  • a change in thickness of the rolling stock over the entire length of the rolling stock in the rolling direction is effected in the continuous rolling process.
  • the continuous procedure thus has the advantage that a small change in the geometry of the rolling stock is achieved by a few rolling passes.
  • At least two rolling pass sequences are required, wherein one is rolled in the longitudinal direction and the other in the width direction.
  • small corrections of the shape of the rolling stock can be carried out after the second roll pass sequence by the rolling stock is rotated a further 90 ° and another roll stitch sequence again in the first direction.
  • the length of the rolling train is minimized by operating the rolling train preferably reversibly, i. that at least one of the rolling mills of the rolling mill is operated reversibly.
  • a high number of stitches is carried out on a few rolling stands.
  • all rolling passes are performed on a single roll stand, i. that the rolling mills only comprises a rolling stand, which is reversible operable.
  • a rolling mill for rolling a rolling stock produced in a block casting process in the form of a truncated pyramid comprising at least one rolling stand for rolling the rolling stock in the first direction and in a second direction transverse to the first direction and means for rotating the rolling stock by 90 °.
  • control and / or regulating device for such a rolling mill, with a machine-readable program code which has control commands which, when executed, cause the control and / or regulating device to carry out a method according to one of the embodiments described above ,
  • the object is further achieved according to the invention by a machine-readable program code for a control and / or regulating device for a rolling train, wherein the program code has control commands that cause the control and / or regulating device for carrying out the method according to one of the embodiments described above.
  • the object is finally achieved according to the invention by a storage medium having stored thereon such machine-readable program code.
  • a slab is shown, which is also referred to as rolling stock 2, which is produced in a block casting process.
  • the slab 2 is in this embodiment, a so-called ingot, ie a block of a semiconductor material such as silicon.
  • the silicon was melted and poured into a mold not shown here. After solidification of the mass in the mold, the slab 2 is pulled out of the mold or pushed out. This is possible due to the slightly conical shape of the mold. Accordingly, the slab 2 also has a double conicity, which manifests itself in a thickness wedge and a wedge, which must be removed during rolling, especially during hot rolling.
  • the side surface 10b forms a lower side surface on which the rolling stock 2 rests during rolling.
  • the opposite side surface 10a is directed substantially upwards and open.
  • the rolling stock 2 in its original form is characterized by a length L which substantially corresponds to the distance between the base surface 4 and the smaller top surface 6.
  • the rolling stock 2 has a varying width B, which is defined perpendicular to the length L, and a likewise varying thickness D, which protrudes from the support plane of the side surface 10b and which rises steadily between the top surface 6 and the base 4.
  • the rolling stock 2 is rolled by means of a rolling line 13, which is indicated in FIG.
  • the rolling train 13 may comprise a plurality of rolling stands, but in the illustrated embodiment it comprises only a single, horizontal rolling stand 12, which in FIG. 3 symbolically indicated by the block 12.
  • the roll stand 12 is operated reversibly, ie the roll stand can reverse a rolling direction 14.
  • a control and / or regulating device 16 is provided, which comprises a stored on a storage medium not shown here program code 18.
  • the program code has control commands, in the execution of which the control and / or regulating device 16 controls the rolling train 13 in a suitable manner for producing the desired geometry of the rolling stock.
  • the rolling stock 2 moved with its base 4 or its top surface 6 forward into a nip not shown here in detail between two work rolls of the roll stand 12 in.
  • the rolling stock 2 is driven forward in the first nip with the top surface 6 in the nip and rolled in the direction of its length L.
  • the roll gap of the roll stand 12 is set such that the side surfaces 10a and 10b at each pass across their entire length with the work rolls come into contact, ie that the work rolls roll in the rolling direction over the entire length of the rolling stock 2.
  • This first roll pass sequence is called a pre-sequence.
  • the wedge-shaped course is inverted from the top surface 6 toward the bottom surface 4, so that the top surface 6 is now thicker than the bottom surface 4.
  • This intermediate geometry of the rolling stock 2a is shown in FIG FIG. 2 shown.
  • the rolling stock 2a has the shape of an irregular hexahedron in which the side surfaces 8a, 8b, 10a, 10b are further formed trapezoidal, but each two adjacent side surfaces 8a, 8b, 10a, 10b converge in the reverse direction.
  • the rolled stock 2a is rotated by about 90 ° after the termination of the pre-sequence, while still resting on its downwardly directed side surface 10b.
  • the rolling stock 2 is aligned in relation to the roll stand 12 in such a way that the rolling stock 2 with its lateral side faces 8a, 8b is moved into the rolling gap of the roll stand 12.
  • the traversing directions of the rolling stock 2a during a second rolling sequence, a so-called spreading sequence is in FIG. 3 shown by the arrow 14.
  • the hatched trapezium shows the rolling stock 2a before the Breitungssequenz and the superimposed, white block 2b represents the rolling stock 2 at the end of the Breitungssequenz.
  • This second roll pass sequence is used to reduce the latitude gradient. At the end of this rolling pass sequence, the desired sheet shape is essentially achieved.
  • FIG. 4 illustrates the orientation of the rolling stock 2 with respect to the nip during the spreading sequence.
  • the hatched square shows the rolling stock 2 and the white square 2b shows a cross section through the rolling stock 2 after the Breitungssequenz.
  • the rolling stock 2 can optionally be rotated again by 90 ° and further rolled in the course of a finished sequence in order to achieve a particularly high precision in the desired shape of the rolling stock 2.
