Definitions
- the invention relates to a method for rolling a rolling produced in a block casting process, a so-called slab or ingot in a rolling train, wherein the rolling before rolling the shape of a truncated pyramid having a base, a top surface and four soflä ⁇ Chen.
- 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.
- slab For some rolled products, it does not make sense to manufacture them as continuous casting products, since too little of these rolling stock is needed. Such rolling is then, for example, preparing, in a block casting process and is referred to as "slab" before the rolling process. After rolling, the slab forms a sheet or a band, which, ideally, a cuboid shape aufwei ⁇ sen. When ingot casting is used a mold which easily is conical, with its cross section tapering downwards. the special shape of the mold, the slab dissolves after solidification completely from the mold wall, when the slab is pressed out of the mold by means of special tongs.
- the slab would take on the shape of the mold and then there is the problem that the double Koni ⁇ ability 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 directed edging rolls are used today for Beeinflus ⁇ solution of the width of the slab, which thicken the hot strip in egg ⁇ nem longitudinal edge region, and thus can reduce the width of the tape in a certain range.
- the invention has for its object to enable a novel Be ⁇ processing a truncated pyramid-shaped 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.
- This object is achieved according to the invention by a method for rolling a rolling stock produced in a block casting process in a rolling train, the rolling stock before rolling having the shape of a truncated pyramid with a base face , a top face and four side faces, in which: during a first rolling pass sequence, two opposite side surfaces of the rolled material in a first direction rolled in such a manner will be that at the end of the first rolling pass sequence, all cross-sectional areas of the rolling stock, which are oriented transversely to the rolling direction, the same surface on ⁇ ,
- the rolling stock is rotated, in particular by 90 °, and
- the same two opposite side surfaces of the rolling stock are rolled in a second direction transverse to the first direction.
- roller here is meant both the slab or the ingot before rolling and its intermediate and final shape which it assumes during or after rolling, and “rolling pass sequence” means 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 porridge ⁇ wedge on.
- the slab thus has the shape of a pyramid ⁇ blunt with a base, a top surface that is smaller than the base surface, and four lateral surface of a side forming surfaces.
- 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 transversely to the length in the supporting plane. And a thickness of the slab extends substantially perpendicular to the support ⁇ level.
- the slab is usually with its top surface forward in a nip between the work rolls of the rolling However, it can also be driven 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 lies in the support plane, remains after rotation in the support plane and it changes only the orientation of the base surface, the top surface and the white ⁇ nic 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 material distribution is performed by viewing the end of the first rolling pass in sequence all the rolling direction cross-sectional areas of the rolled material between the base and the top surface have the same FLAE ⁇ surface.
- 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.
- ⁇ bar wherein the original area gradient is not completely degraded in the rolling Rich ⁇ tung or overcompensated.
- ⁇ bar wherein the original area gradient is not completely degraded in the rolling Rich ⁇ tung or overcompensated.
- the rolling pass sequence can be carried out on several rolling stands, wherein a rolling stand is provided in particular for each pass. However, 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 roll 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 a new Dickengradient, but in the opposite direction to the first Dickengra- used to produce.
- the length of the rolling stock is increased in ⁇ particular.
- the rolling stock is rotated by 90 ° with the aid of suitable means, so that it is driven laterally into the nip, as it were.
- a wedge of the rolling stock is degraded in the context of the second rolling pass sequence.
- Dismounted in this case means that after the second roll pass sequence a uniform width of the rolling stock is set and there is no latitudinal gradient
- Important in the rotation is that the side surface which lies on a roller course of the rolling train, even after the rotation on the roller table
- the rotation about the normal vector of the side surface lying on the roller table is effected in particular by means of a revolving gear, which is characterized by three features:
- the table rollers are right and left slightly ver ⁇ different diameters (ie they are not cylinders, special countries truncated cones or two cylinders differing ⁇ cher diameter composed).
- roller table rollers are arranged on the roller table in such a way that rollers (eg all straight lines) are alternately arranged on one side. numerous rolls) with their large diameter of rolls (eg all odd-numbered rolls) with their smaller diameter followed to the same side.
- 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 Walzrich ⁇ tion is effected in the continuous rolling process.
- the continuous approach thus has the advantage that by a few rolling passes a larger modifiers ⁇ alteration of the geometry of the rolled stock is achieved the advantage.
- 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 performed after the second roll pass sequence by the rolling stock is rotated a further 90 ° and another Walzstichsequenz he ⁇ neut takes place in the first direction.
- the length of the rolling train is minimized by the rolling train is preferably operated reversibly, ie that at least ei ⁇ nes of the rolling stands of the rolling mill is operated reversibly.
- a high number of passes is performed on a few rolling stands.
- all rolling passes are performed on a single rolling mill, which means that the rolling mill comprises only one roll stand, which is reversibly operable.
- a rolling mill for rolling a rolled material produced in a block casting method in the form of a truncated pyramid, umfas ⁇ send at least one roll stand for rolling of the rolling stock in the first direction and in a second direction transverse to said first direction and means for rotating the rolling stock around 90 °.
