Abstract
Description
Die Erfindung betrifft ein Verfahren sowie eine Vorrichtung zur Herstellung von warmgewalztem Stahlband aus stranggegossenem Vormaterial, vorzugsweise Dünnbrammen, mit in einer Hitze aufeinanderfolgenden Arbeitsschritten eines CSP-Verfahrens, wobei das Vormaterial nach Erstarren in Längen unterteilt wird, die dem gewünschten Bundgewicht entsprechen und die Dünnbrammen in einem Ausgleichsofen homogenisiert, anschließend in einer Vorwalzstraße vorgewalzt, in einer Fertigstraße fertiggewalzt, in einer Kühlzone abgekühlt und auf einen Haspel aufgewickelt werden.The invention relates to a method and a device for producing hot-rolled steel strip from continuously cast starting material, preferably thin slabs, with successive steps of a CSP process in heat, the starting material being subdivided into lengths corresponding to the desired coil weight and the thin slabs in homogenized in a compensating furnace, then pre-rolled in a roughing train, finish-rolled in a finishing train, cooled in a cooling zone and wound onto a reel.
Ein derartiges Verfahren und eine derartige Vorrichtung sind z.B. durch die DE 40 09 860 A1 bekannt geworden. Es hat sich jedoch gezeigt, daß Stahlqualitäten, welche ein temperaturkontrolliertes Walzen erfordern mit diesem Konzept nur begrenzt hergestellt werden können. Insbesondere sind Stahlqualitäten, die eine Temperatur oberhalb der maximal möglichen Ausgleichsofen-Temperatur vor dem ersten Stich und eine deutlich niedrigere Temperatur vor dem zweiten Stich benötigen, mit diesem Konzept nicht flexibel, im Hinblick auf Enddicke und Endwalztemperatur walzbar.Such a method and device are e.g. made known by DE 40 09 860 A1. However, it has been shown that steel grades which require temperature-controlled rolling can only be produced to a limited extent with this concept. In particular, steel grades that require a temperature above the maximum possible equalization furnace temperature before the first pass and a significantly lower temperature before the second pass are not flexible with this concept, with regard to the final thickness and finish rolling temperature.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren sowie eine entsprechende Vorrichtung zur Herstellung von warmgewalztem Stahlband dahingehend zu verbessern, daß alle bekannten Stahlqualitäten absolut flexibel gewalzt werden können.The invention has for its object to improve a method and a corresponding device for the production of hot-rolled steel strip in such a way that all known steel qualities can be rolled absolutely flexibly.
Diese Aufgabe wird verfahrensmäßig durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Durch den Schritt 1 können neben den bisher möglichen Stahlqualitäten auch solche Stahlqualitäten gewalzt werden, bei denen der erste Stich im Vorverformungsgerüst Temperaturen erfordert, die über den, z. B. durch die Temperaturbeständigkeit der Rollen, ihrer Lager und Antriebe bestimmten maximalen Temperatur des Ausgleichsofen liegen.This object is achieved procedurally by the characterizing features of claim 1. In addition to the previously possible steel grades, step 1 can also be used to roll those steel grades in which the first pass in the pre-forming stand requires temperatures which exceed the z. B. by the temperature resistance of the rollers, their bearings and drives certain maximum temperature of the expansion furnace.
Durch den Schritt 2 ist eine optimale Gefügeausbildung möglich, so daß unverfestigtes, entspanntes Material für die Fertigstraße zur Verfügung steht. Dies wird durch eine materialspezifische Verweilzeit des Walzguts in der Rekristallisationszone erreicht.
Der Schritt 3 gewährleistet, daß die Temperatur für den ersten Stich in der Fertigstraße nach walztechnologischen Gesichtspunkten, entsprechend des notwendigen Temperaturverlaufes in der Fertigstraße für alle Stahlqualitäten optimal eingestellt werden kann.
Die Merkmale des Anspruchs 2 gestatten auch längere Verweilzeiten in der Rekristallisationszone, ohne daß diese eine zu große räumliche Ausdehnung aufweist, wobei der Warmhalteofen nach Anspruch 6 auch kürzere Wartungsarbeiten am Fertiggerüst zuläßt, ohne daß die vorhergehenden Einheiten gestoppt werden müssen.The features of
Vorrichtungsmäßig wird die Aufgabe durch die Merkmale des Anspruchs 3 gelöst.In terms of the device, the object is achieved by the features of
Das Merkmal des Anspruchs 4 erlaubt ein kurzfristiges, schnelles Aufheizen des Walzgutes, so daß schnelle Änderungen zwischen den Walzgutqualitäten keine Probleme darstellen.The feature of
Soll die CSP-Anlage mit größerem Ausstoß gefahren werden, so bietet sich wie bekannt an, zwei parallel angeordnete Gießmaschinen auf eine Walzstraße arbeiten zu lassen. Dabei hat sich bewährt, eine Fähre zwischen die Heizvorrichtung und die Ausgleichsöfen zu setzen, welche die nachfolgenden Anlagenkomponenten alternierend mit Walzgut zu versorgen vermag. Ist dabei die nachfolgende Walzstraße fluchtend mit einer der Gießmaschinen und Ausgleichsöfen vorgesehen, so hat es sich als vorteilhaft erwiesen, der Fähre noch einen weiteren Ausgleichsofen nachzuordnen.If the CSP system is to be operated with a higher output, then offers as is known, to let two casting machines arranged in parallel work on a rolling mill. It has proven useful to put a ferry between the heating device and the equalizing furnaces, which can alternately supply the subsequent system components with rolling stock. If the subsequent rolling train is aligned with one of the casting machines and leveling furnaces, it has proven to be advantageous to place a further leveling furnace behind the ferry.

Daran anschließend ist eine Induktionsheizung 6 vorgesehen, die bei Bedarf die aus dem Ausgleichsofen 4 austretenden Dünnbrammen 3 auf Temperaturen über 1150°C aufzuheizen vermag. Der Induktionsheizung 6 schließt sich ein Zunderwäscher 7 und eine Vorwalzstraße, hier ein Vorverformgerüst 8 an, dem die Rekristallisationszone 9 folgt. In der Rekristallisationszone 9 ist eine Aufwickelvorrichtung 10 und eine Abwickelvorrichtung 11, z.B. eine Coilbox vorgesehen. Der Aufwickelvorrichtung 10 und der Abwickelvorrichtungen 11 ist ein Warmhalteofen 12 nebengeordnet, in den gegebenenfalls fertiggewickelte Coils zu Zwischenlagerungs- und Rekristallisationszwecken gespeichert werden können.An
In Walzrichtung hinter der Abwickelvorrichtung 11 ist eine Kühlvorrichtung 13 vorgesehen, mittels der das Walzband auf optimale Temperaturen für die anschließende Fertigstraße 14 gekühlt und gegebenenfalls entzundert werden kann.
