Definitions

  • the invention relates to a method for producing a rolling stock rolled in a rolling train of a rolling mill.
  • a generic method is eg off WO-A 20070738411 known.
  • the invention relates to a control and / or regulating device for a rolling mill for the production of rolled rolled stock.
  • the invention relates to a rolling mill for the production of rolled rolled stock.
  • the invention relates to machine-readable program code and a storage medium with machine-readable program code.
  • production plans are made for the utilization of corresponding installations for producing a corresponding product.
  • a corresponding process flow plan is provided whereby the product entering a plant is converted into a desired product leaving the plant.
  • a flow chart of the rolling process for a particular product is determined.
  • Such a process flowchart relating to a rolling stand or to a plurality of rolling stands, in particular a rolling train, is called pass schedule.
  • a single pass through the rolling stock is considered by a rolling mill as a stitch.
  • a variety of products are produced by a rolling mill, which are dependent on the operation of the rolling mill.
  • the object of the present invention is to reduce production losses of rolling mills, in particular cast roll mills, by undesired process deviations which influence the production of an outlet product.
  • the object is achieved by a method for producing a rolled product rolled in a rolling train of a rolling plant, in particular casting rolling mill, wherein the rolling mill is operated continuously by the rolling stock during the scheduled operation of a device supplying the rolling mill, in particular a casting device and / / or a Walzgutwickel worn until at least one Walzgutzu slaughterpiece is integrally formed by the rolling continuously enters the finishing train and is rolled in the finishing train continuously to a first outlet product.
  • the operation of the rolling mill is monitored for the occurrence of a rolling process affecting the deviation from the scheduled operation of the rolling mill, which is checked when the deviation occurs, whether in consideration of the deviation, a second different from the first Discontinued product can still be produced.
  • the operation of the rolling mill is changed from the continuous operation in a discontinuous operation.
  • the Walggutzu 2008 serves to supply rolling stock in the rolling mill.
  • This can, for example, be a casting device in cast roll composite systems.
  • this may be e.g. also a Walzgutwickel adopted, in particular Walzgutabwickel realized be, which the rolling mill by unwinding of unwound rolled material to be processed rolling stock, in particular hot strip, feeds.
  • This can be designed in particular as a reel or as a coil box for hot strip.
  • a plurality may be provided to Walzgutwickel drivenen for feeding rolling stock in the rolling mill.
  • the Walggutzu slaughterhouse is designed such that by means of this rolling continuously in the rolling mill can be introduced.
  • the operating mode of the rolling mill By changing the operating mode of the rolling mill from a continuous operation to a discontinuous operation, also called batch mode, the operation of the rolling mill is made more flexible, since the aggregates of the rolling mill are decoupled from each other. This makes it possible to roll pass patterns that are not rollable from a technological point of view during continuous operation. This makes it possible to maintain a rolling operation, although neither the first outlet product, nor an alternative outlet product can be produced in the continuous operation of the rolling mill.
  • Deviation is understood to mean a process deviation by which the first, originally produced or desired outlet product can no longer be produced. The deviation can be predictable or unexpected.
  • non-manufacturability includes both a "hard”, ie technical, non-manufacturability, ie a discontinued product is technically under the given boundary conditions easy not to produce, as well as a "soft" Tinher dichkeit, ie an outlet product is technically manufacturable, but undesirable by the operator, for example, due to economic reasons, since the technically manufacturable outlet product, for example, has a low manufacturing priority and thus possibly have a long storage time, which, for example for logistical or financial reasons is not desirable.
  • it is also preferably checked whether a desired flatness and a desired profile can be set in the case of an existing deviation, so that the target corridor for flatness and profile is achieved.
  • the second outlet product when the second outlet product is producible, the second outlet product is produced. This is preferably done automatically. For this a stitch plan calculation takes place under the changed, u.a. caused by the process deviations, boundary conditions. If a pass plan or an alternative expiry product can be determined that is still processable in view of the deviation, then this pass schedule or alternative discontinued product is produced in continuous operation. Thereby, a continuous operation of the rolling mill can be maintained.
  • the second outlet product in the case of manufacturability of the second outlet product, it is selected whether the second outlet product is produced or the operation of the rolling plant is changed to a discontinuous operation.
  • This is particularly useful when only not yet desired by the customer outlet products are produced or only products can be produced with very low production priority. In such cases, it may be appropriate, despite manufacturability of an alternative outlet product to switch to a discontinuous operation of the rolling mill to produce the first outlet product or a higher second outlet product with higher manufacturing priority, than that in continuous operation producible outlet products.
  • the decision as to whether to proceed to a discontinuous operation in the case of the present producible second discontinued product can be made manually or automatically.
  • the first or a further second outlet product can be produced in discontinuous operation.
  • the further second outlet product may be identical or different from the second outlet product determined for continuous operation.
  • Such a check makes it possible, in particular before changing the operation, to determine which outlet product is to be produced in discontinuous operation.
  • the first run-out product, which has been produced in continuous operation may be produced due to the presence of the deviation, although not continuous operation, but still in discontinuous operation. This makes it possible to realize a production strategy that is as optimal as possible, since in particular high-priority discontinued products, which, for example, were produced in continuous operation, can also be produced even further by changing over the operating mode. Thus, if necessary, a sales order can still be processed completely, although this would not have been possible in continuous operation.
  • the change takes place in the discontinuous operation by separating, in particular cutting, of the rolling stock between the Walggutzu slaughter earlier, in particular the casting device or the Walzgutwickelinnate, and the finishing train takes place.
  • the cutting can be done with conventional tools, in particular in a mechanical or thermal manner.
  • a Walzgutzu scent Anlagen of Walzgutzu classroom when changing the operation to the discontinuous operation, a Walzgutzu slaughter of the plant or a winding speed of Walzgutwickel issued, at least briefly reduced and / or increases a rolling speed of the finishing train.
  • the distance of successive rolling stock is increased, whereby a more flexible handling of the individual rolling stock can take place.
  • the casting speed can be reduced compared to the casting speed in continuous operation.
  • at least the entry speed is increased in the rolling train, in particular finishing train.
  • the rolling stock between Walzgutzu slaughter and finishing train is cut at least twice to increase a distance of successively rolling into the finishing train, with the first and second cut limited part of the rolling removed from the rolling process becomes. It is thereby achieved that the gap between the separated by the cutting rolling parts is further increased by a part of the rolling stock is separated from the original strand. As a result, the rolling of an outlet product is further flexibilized. This separated part of the rolling stock can be stored if necessary, or forms scrap. The latter is to the effect acceptable, since if necessary, with insufficient distance of the rolling stock from each other, the entire rolling stock in the plant would form scrap, as possibly no discontinued product can be produced.

  • the casting device 6 may be formed, for example, as a mold. Likewise, the casting device 6 may be designed as a roller casting machine. There are no restrictions on the usable pouring equipment.
  • the rolling mill 1 In scheduled operation, the rolling mill 1 is operated in a so-called endless operation, i. It is cast continuously metal and fed directly to a rolling process, in particular a finish rolling process. The rolling stock thus extends in the scheduled operation continuously from the casting device 6 to the finishing train 2.
  • a rolling stock G emerging from the casting device 6 passes through the rolling mill 1.
  • this rolling stock G can first pass through units, such as an oven, a segment cooling device, a descaling device and / or a roughing mill, in particular a high reduction mill 11, before the rolling stock section G enters the finishing train 2.
  • the rolling stock G passes through the finishing train 2 and optionally further downstream of the finishing train 2 in mass flow direction aggregates, such as a cooling section and / or a coiler, by means of which the rolling stock G is wound.

  • the control and / or regulating device 8 monitors the scheduled operation of the rolling mill 1, in particular the scheduled operation of the finishing train 2 according to a first pass schedule for producing a first outlet product A with the thickness D.
  • An expected deviation from the scheduled operation for example, the emptying of the pouring device 6 be because the supply of liquid metal can not be maintained. Such a process is usually foreseeable. The operating staff knows when this condition will occur. However, this usually undesirable process deviation must be reacted.
  • Unforeseeable deviations from the scheduled operation for producing the first outlet product A according to the first pass plan can be caused, for example, by a short-term increase or decrease in the casting speed of the casting device 6, by a malfunction of an aggregate, for example a furnace and / or a cooling device, in particular a segment cooling device , which is upstream of the finishing train 2 in the mass flow direction or are, or by technical problems during coiling of the belt on the coiler, which is downstream of the finishing train 2.
  • Such deviations require an instantaneous reaction to the deviation, since, for example, in the case of mass flow changes, for example by a short-term casting speed change, the mass flow downstream and / or upstream relative to the mass flow through the finishing train 2 is different. This leads to significant problems in the rolling mill 1. In particular, a wave formation or a crack of the rolling G occur.
  • Such a deviation can also be caused by other influences which are not directly caused by a change in the mass flow through the rolling mill 1.
  • An example of this is e.g. a desired deviation in the rolling stock temperature at a certain point before the rolling train, such as when entering the finishing train 2. This can cause the discontinued product A with the thickness D is no longer rollable, since the material when entering due to the low temperature too hard to roll it to the desired final thickness.

Is a roughing street, for example in the form of a High Reduction Mill 11, the finishing train 2 upstream in the mass flow direction, it can be advantageous to separate the rolling stock between finishing train 2 and High Reduction Mill, since the rolling stock already has a correspondingly small thickness.
