Definitions

  • the invention relates to a method for producing a rolled rolled in a rolling mill of a rolling mill. Furthermore, the invention relates to a control and / or regulating device for a rolling mill for the production of rolled rolled stock. In addition, the invention relates to a rolling mill for the production of rolled rolled stock. Furthermore, 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 large number of products are produced by a rolling plant, which depend on the mode of operation of the rolling mill. If the process is disrupted during the processing of a rolling stock in a rolling mill, the conditions for rolling the rolling stock in the rolling mill and the conditions for rolling the rolling stock presupposed for the pass schedule deviate. Due to this deviation, it can happen that a certain product can no longer be produced according to its pass schedule due to an undesired process deviation.
  • the object of the present invention is to reduce production losses of rolling mills, in particular cast roll mills, by undesirable 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 deviation affecting the rolling process from the scheduled operation of the rolling mill, wherein it is checked when the deviation occurs, whether, in view of the deviation, a second from the first separate outlet product is still produced.
  • the operation of the rolling mill is changed from the continuous operation to a discontinuous operation.
  • the Walggutzu slaughterhouse serves to supply rolling stock in the rolling mill.
  • This can, for example, be a casting device in cast roll composite systems. However, this may be e.g. also a Walzgutwickel featured, in particular Walzgutabwickelein- be, which feeds the rolling mill by unwinding of unwound rolled to be processed rolling stock, in particular hot strip.
  • This can be designed in particular as a reel or as a coil box for hot strip.
  • 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 stitch plans that can not be rolled in continuous operation from a technological point of view. 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 available under the given boundary conditions. can not be produced, as well as a "soft" non-manufacturability, ie an outlet product is technically producible, but undesirable by the operator, for example, due to economic reasons, since the technically producible discontinued product, for example, has a low manufacturing priority and thus possibly have a long shelf life
  • it is also preferably checked with regard to the technical manufacturability whether a desired flatness and a desired profile can be set in the event of a 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 expedient, despite the producibility of an alternative outlet product, to change to a discontinuous operation of the rolling plant in order to produce the first outlet product or a higher second outlet product with a higher production 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 discontinued 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. In this way, if necessary, a sales order can still be completely rejected, 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.
  • Cutting can be done with conventional tools, especially in a mechanical or thermal manner.
  • a Walzgutzu 911 familia of Walzgutzu 1900 when changing the operation to the discontinuous operation, a Walzgutzu 1900 elegantly of Walzgutzu 1900 with rolling stock, in particular a casting speed of the casting or a winding speed of Walzgutwickel adopted, at least briefly reduced and / or increases a rolling speed of the finishing train.
  • the distance of successive rolled goods 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 finish rolling mill.
  • the rolling stock between Walzgutzu slaughter and finishing train is cut at least twice to increase a distance of successively rolling into the finishing rolling mill, wherein the first and second cut limited part of the rolling stock removed from the rolling process becomes. It is thereby achieved that the gap between the rolling-stock parts separated from one another by cutting is further increased by separating a part of the rolling stock 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.

Abstract

L'invention concerne un laminoir (1) destiné à fabriquer un produit laminé (G), un code de programme (9) lisible par machine, un support d'enregistrement (10), un dispositif de commande et/ou de régulation (8) pour un laminoir (1) destiné à fabriquer un produit laminé (G) et un procédé de fabrication d'un produit laminé (G) sur un train de laminage (2) d'un laminoir (1), en particulier un laminoir à coulée continue. En fonctionnement normal, le produit laminé est fait d'une seule pièce entre un dispositif (6, 6') alimentant le laminoir (1) en produit à laminer, en particulier un dispositif de coulée (6) et/ou un dérouleur de produit à laminer (6'), et au moins un train finisseur (2) placé en aval du dispositif (6, 6') d'alimentation en produit à laminer dans la direction d'avancée du produit. Le produit à laminer (G) pénètre en continu dans le train finisseur (2) où il est laminé en continu pour donner un premier produit de sortie (A). Le fonctionnement du laminoir (1) est surveillé afin de détecter un écart, par rapport au fonctionnement normal du laminoir (1), pouvant affecter le processus de laminage. En présence de cet écart, on vérifie (100, 101) si, compte tenu de cet écart, il est encore possible de fabriquer (102) un deuxième produit de sortie (A*), différent du premier. Si le deuxième produit de sortie ne peut pas être fabriqué, le fonctionnement du laminoir (1) est commuté d'un fonctionnement continu en un fonctionnement discontinu (106). Il est ainsi possible de fournir des moyens destinés à réduire les arrêts de production causés par des écarts intempestifs du processus dans un laminoir.
