Abstract

The invention relates to a method and an installation for the production of hot-rolled steel strip from continuously cast material, preferably thin slabs with working steps of a CSP method taking place in succession at the same temperature, the thin slabs leaving a soaking furnace being heatable to temperatures above the maximum temperature achievable in the soaking furnace, the thin slabs being left a sufficient time to recrystallise after the roughing pass, and the thin slabs then being cooled to the rolling temperature for the finishing train.

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 the production of hot rolled Steel strip made of continuously cast material, preferably Thin slabs, with successive ones in a heat Steps of a CSP process, the primary material after solidification in lengths is divided into the desired bundle weight correspond and the thin slabs in one Compensating oven homogenized, then in one Rough rolled mill, in a finishing train finish rolled, cooled in a cooling zone and opened to wind up 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 one Devices are e.g. through DE 40 09 860 A1 known. However, it has been shown that Steel grades, which are temperature controlled With this concept, rollers require only a limited amount can be produced. In particular are Steel grades that are above the temperature maximum possible compensating furnace temperature the first stitch and a significantly lower one Need temperature before the second stitch with this concept is not flexible in terms of final thickness and final rolling temperature can be rolled.

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 is based on the object Method and a corresponding device for the production of hot rolled steel strip to improve that all known Steel grades are rolled with absolute flexibility can.

Diese Aufgabe wird verfahrensmäßig durch die 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 task is procedurally carried out by the Features of claim 1 solved. By the Step 1 can next to the previously possible Steel grades also rolled such steel grades where the first stitch in the pre-deformation framework Requires temperatures above that z. B. by the temperature resistance of the rollers, their bearings and drives determine maximum Temperature of the equalizing 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.Through step 2 is an optimal structure possible, so that unconsolidated, relaxed Material for the finishing train is available stands. This is done through a material specific Rolling time in the recrystallization zone reached.

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.Step 3 ensures that the temperature for the first pass in the finishing train after rolling technology Viewpoints, accordingly the necessary temperature profile in the finishing train optimally set for all steel qualities can be.

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 claim 2 also allow longer dwell times in the recrystallization zone, without this being too large has, wherein the holding furnace according to claim 6 also shorter maintenance work on the finishing stand allows without the previous units must be stopped.

Vorrichtungsmäßig wird die Aufgabe durch die Merkmale des Anspruchs 3 gelöst.In terms of the device, the task is performed by the Features of claim 3 solved.

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 claim 4 allows one short-term, quick heating of the rolled stock, so that rapid changes between the rolling stock qualities pose no problems.

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.Should the CSP system run with greater output are, as is well known, two casting machines arranged in parallel on a rolling mill to let work. It has proven itself a ferry between the heater and the To set compensating ovens which are the following Plant components alternating with rolling stock able to supply. Here is the following Rolling mill in alignment with one of the casting machines and compensation furnaces provided, it has proven to be proven advantageous to the ferry yet another Subsequent compensation oven.
