Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Anlage zur Oberflächenbearbeitung eines Produktes, insbesondere einer Dünnbramme, zur Beseitigung von Oberflächenfehlern, -verunreinigungen und dergleichen, innerhalb einer Stranggießanlage, bei der das Produkt nach dem Gießvorgang einen Ofen durchläuft und anschließend einer Walzstraße zugeführt wird.The invention relates to a method and a surface treatment plant of a product, especially a thin slab, for the removal of Surface defects, impurities and the like, within a continuous caster, in which the product goes through an oven after the casting process and subsequently a rolling mill supplied becomes.

Bei den bekannten Verfahren und Vorrichtungen sind somit Oberflächenbearbeitungseinrichtungen vorgesehen, welche für Bearbeitungstemperaturen von mehr als 500°C ausgelegt sein müssen. Oberflächenbearbeitungseinrichtungen dieser Art erfordern hohe Betriebs- und Investitionskosten.In the known methods and devices are thus surface processing equipment provided which for Processing temperatures of more than 500 ° C must be designed. Surface treatment equipment of this type require high operating and investment costs.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Anlage zu schaffen, mit denen eine Oberflächenbearbeitung von Produkten, inbesondere von Dünnbrammen, innerhalb einer Stranggießanlage erreicht wird, bei der die Betriebs- und Investitionskosten für die Oberflächenbearbeitungseinrichtung verringert werden.The invention is based on the object Process and plant to create a surface treatment of products, especially thin slabs, within a continuous caster is achieved at which the operating and investment costs for the surface treatment device be reduced.
Diese Aufgabe wird erfindungsgemäß durch ein Verfahren gelöst, indem die Produkte mindestens an der Oberfläche nach dem Gießvorgang vollständig abgekühlt werden, anschließend die Oberflächenbearbeitung im kalten Zustand durchgeführt wird und die Produkte danach im Ofen auf Walztemperatur gebracht und danach der Walzstraße zugeführt werden. Die Vorrichtung sieht vor, dass vor der Oberflächenbearbeitungseinrichtung eine Einrichtung zur vollständigen Abkühlung des Produktes auf eine Temperatur unterhalb von 500°C, vorzugsweise unterhalb von 300°C, insbesondere bis Raumtemperatur, eingebaut ist.This object is achieved by a Procedure solved, by placing the products at least on the surface after the pouring process Completely chilled be, then the surface treatment is carried out in a cold state and the products are then brought to rolling temperature in the oven and then the rolling mill supplied become. The device provides that in front of the surface processing device a facility to complete cooling down of the product to a temperature below 500 ° C, preferably below from 300 ° C, in particular up to room temperature.
Aufgrund der Abkühlung der Produkte nach dem Gießprozess auf einen kalten Zustand ist es möglich, Bearbeitungsverfahren einzusetzen, die bisher bei der Oberflächenbearbeitung nicht berücksichtigt werden konnten. Die Anforderungen an die Werkzeuge wie z.B. Schleifscheiben oder Fräser werden von den konventionell erhältlichen Werkzeugen erfüllt. Besondere Anforderungen an z.B. die Temperaturbeständigkeit eines Schleifbandes sind nicht erforderlich.Due to the cooling of the products after the casting process on a cold condition it is possible machining processes to be used that have not been taken into account in surface treatment could become. Tool requirements such as grinding wheels or router are available from the conventionally available Tools met. Special requirements for e.g. the temperature resistance an abrasive belt is not required.
Die Oberflächenbearbeitung erfolgt beispielsweise durch Schleifen, Flämmen, Bürsten oder Fräsen, wobei insbesondere das Schleifen eingesetzt wird.The surface treatment is done for example by grinding, flaming, to brush or milling, grinding being used in particular.
Die Verfahrensschritte für die Oberflächenbearbeitung der Produkte werden in einer ersten Ausführung innerhalb einer Produktionslinie (P) zwischen Gießprozeß und Walzprozeß durchgeführt.The process steps for surface processing of the products are in a first execution within a production line (P) performed between the casting process and the rolling process.
Eine andere Ausführung sieht vor, dass das Produkt nach dem Gießprozeß aus der Produktionslinie (P) in eine Seitenlinie (S) gebracht, eine Oberflächenbearbeitung durchgeführt und das Produkt vor dem Ofen wieder in die Produktionslinie (P) gebracht wird.Another version provides that the product after the casting process from the Production line (P) brought into a side line (S), a surface treatment carried out and the product back into the production line before the oven (P) brought.
Als Ausgestaltung wird vorgeschlagen, dass die Einrichtung zur Abkühlung ein Kühlbett, insbesondere ein Wasserbecken ist.It is proposed as an embodiment that that the facility to cool down a cooling bed, especially a pool of water.
Vorteilhaft ist ferner, dass die Kühleinrichtung gleichzeitig als Speicherplatz, Ablage oder anderer Lagereinrichtung für die Produkte eingesetzt wird.It is also advantageous that the cooling device at the same time as storage space, storage or other storage facility for the Products is used.
Weitere Vorteile ergeben sich daraus, dass zwischen der Oberflächenbearbeitungseinrichtung und dem Ofen weitere Zwischenlager vorgesehen sind.Other advantages result from that between the surface treatment device and additional intermediate storage is provided for the furnace.
Als eine Weiterentwicklung ist vorgesehen, dass die Produkte nach der Oberflächenbearbeitung und vor dem Ofen in einer zusätzlichen Ofeneinrichtung erwärmt werden.As a further development it is envisaged that the products after surface treatment and in front of the oven in an additional Furnace heated become.
Die zusätzlichen Einrichtungen zur Abkühlung und Oberflächenbearbeitung und/oder Lagerung und/oder Erwärmung sind innerhalb einer Produktionslinie (P) zwischen Stranggießanlage und Ofen angeordnet oder werden außerhalb der Produktionslinie (P) in einer Seitenlinie (S) zwischen Stranggießanlage und Ofen vorgesehen.The additional facilities for cooling down and surface finishing and / or storage and / or heating are within a production line (P) between the continuous caster and furnace are arranged or are off the production line (P) in a side line (S) between the continuous caster and furnace.
Insbesondere wird das erfindungsgemäße Verfahren zur Oberflächenbearbeitung von Edelstählen eingesetzt, da eine Oberflächenbearbeitung bei diesem Werkstoff besonders häufig durchgeführt wird.In particular, the method according to the invention for surface processing of stainless steels used because a surface treatment particularly common with this material is carried out.
Ausführungsbeispiele der Erfindung werden anhand von sehr schematischen Zeichnungen näher beschrieben. Es zeigen:Embodiments of the invention are described in more detail using very schematic drawings. Show it:
