Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren zur Verbesserung der Oberflächenqualität einer stranggegossenen Bramme, insbesondere einer Dünnbramme mit einer Gießdicke von maximal 100 mm, wobei die Bramme mit einem Gießschlackenfilm und einer Zunderschicht überzogen ist, wobei die Bramme nach dem Gießen entzundert und in einer Fertigstraße gewalzt wird.The present invention relates to a method for improvement the surface quality of a continuously cast slab, in particular a thin slab with a maximum casting thickness of 100 mm, the Slab covered with a layer of pouring slag and a layer of scale is, the slab descaled after casting and in one Finishing mill is rolled.
Nach dem Walzen von Dünnbrammen in einer Fertigstraße weist das gewalzte Warmband an seiner Oberfläche sehr häufig Streifen oder Schlieren, sogenannte "streaks" auf. Bei einer Vielzahl von späteren Verwendungen des Warmbandes sind diese Streifen tolerierbar. Bei besonders hohen Qualitätsanforderungen hingegen sind die Streifen nicht tolerierbar. Bei derartigen Anwendungen werden daher nach wie vor Dickbrammen mit einer Gießdicke von mindestens 150 mm eingesetzt. Dies ist jedoch vergleichsweise teuer und aufwendig.After rolling thin slabs in a finishing train, this shows rolled hot strip very often strips or Streaks, so-called "streaks". In a variety of later These strips are tolerable when the hot strip is used. At The strips, on the other hand, have particularly high quality requirements intolerable. In such applications, therefore before thick slabs with a casting thickness of at least 150 mm. However, this is comparatively expensive and complex.
Die Aufgabe der vorliegenden Erfindung besteht somit darin, ein Verfahren zur Verbesserung der Oberflächenqualität einer stranggegossenen Bramme zu schaffen, bei dem die Streifen und Schlieren nicht mehr auftreten bzw. zumindest deutlich reduziert sind, so daß auch für Anwendungen mit hohen Qualitätsanforderungen als Ausgangsmaterial Dünnbrammen einsetzbar sind. The object of the present invention is therefore a Process for improving the surface quality of a continuous cast Create slab using the streaks and streaks no longer occur or are at least significantly reduced, so that also for applications with high quality requirements as raw material Thin slabs can be used.
Die Aufgabe wird dadurch gelöst, daß auf die Bramme vor dem Entzundern oder während des Entzunderns ein von Wasser verschiedenes Reaktionsmittel aufgebracht wird. Dem Aufbringen des Reaktionsmittels kann eine herkömmliche hydraulische, mechanische oder pneumatische Entfernung der auf der Bramme aufliegenden Zunderschicht vorausgehen.The object is achieved in that the slab before descaling or a different one from water during descaling Reagent is applied. The application of the reactant can be a conventional hydraulic, mechanical or pneumatic removal of the scale layer lying on the slab go ahead.
Weitere Vorteile und Einzelheiten ergeben sich aus den Unteransprüchen sowie der nachfolgenden Beschreibung eines Ausführungsbeispiels.Further advantages and details emerge from the subclaims and the following description of an embodiment.
Dabei zeigt die einzige Figur eine Dünnbrammengießanlage mit nachgeschalteter Fertigstraße.The only figure shows a thin slab caster with a downstream Finishing train.
Gemäß der Figur wird in einer Dünnbrammengießanlage 1 eine Bramme 2 mit einer Gießdicke d gegossen. Die Gießdicke d beträgt zwischen 20 und 100 mm, z.B. 50 mm.According to the figure, a slab is in a thin slab caster 1 2 cast with a casting thickness d. The casting thickness d is between 20 and 100 mm, e.g. 50 mm.
Nach dem Gießen wird die Bramme 2 durch die Führungsrollen 3 von
der Senkrechten in die Waagerechte umgebogen. Danach wird die Bramme
2 durch Vorwalzen 4 vorgewalzt, z.B. von 50 mm auf 35 mm. Das
Vorwalzen erfolgt vorzugsweise vor oder unmittelbar nach dem Durcherstarren
der Bramme 2.After casting, the
Damit das zu gießende flüssige Metall in der Dünnbrammengießanlage
1 nicht an dieser anhaftet, wird in der Dünnbrammengießanlage
Gießpulver verwendet, welches als Schlackenschicht zwischen Kokillenwand
und Strangschale zu liegen kommt. Die Gießschlacke verbindet
sich bei den hohen Gießtemperaturen mit der Oberfläche der zu
gießenden Bramme 2 und bildet so einen Schlackenfilm auf der Oberfläche
der Bramme 2. Ferner ist die Bramme 2 beim Verlassen der
Dünnbrammengießanlage 1 noch so heiß, daß sich beim Hinzutreten des
Luftsauerstoffs sofort eine Oxidschicht (= Zunderschicht) auf der
Bramme 2 bildet. Diese beiden Schichten, nämlich der Schlackenfilm
und die Zunderschicht, müssen vor dem Walzen möglichst vollständig
beseitigt werden.So that the liquid metal to be cast in the thin slab caster
1 does not adhere to it, is in the thin slab caster
Casting powder used, which as a layer of slag between the mold wall
and strand tray comes to rest. The pouring slag connects
at the high casting temperatures with the surface of the
Hierzu wird die Bramme 2 aus Düsen 5 mit einem Reaktionsmittel 6
bespritzt, welches im Wasserglas emulgiert ist. Danach wird die
Bramme in einem Tunnelofen 7 ca. 20 bis 30 Minuten aufgeheizt und
sodann im Entzunderer 8 entzundert. Nach dem Entzundern wird die
Bramme 2 in einer mehrgerüstigen - gemäß Ausführungsbeispiel viergerüstigen
- Fertigstraße 9 gewalzt und auf ein Haspel 10 gewickelt.
Die Fertigstraße 9 kann selbstverständlich auch mehr oder weniger
als vier Gerüste aufweisen, z.B. sechs oder zwei.For this purpose, the
Durch das Reaktionsmittel 6 ist die Lösbarkeit der Zunderschicht
und des Schlackenfilms erheblich besser als ohne das Reaktionsmittel
6. Dadurch werden diese beiden Schichten beim Entzundern fast
vollständig entfernt, so daß nach dem Walzen fast keine Streifen
und Schlieren mehr auf dem gewalzten Band vorhanden sind. Das
Aufheizen der Bramme 2 dient dabei dem Aufschmelzen oberflächennaher
Bereiche der Bramme 2, stellt also eine thermische Behandlung der
Bramme 2 dar. Das Entzundern der Bramme 2 im Entzunderer 8 erfolgt
auf konventionelle Weise, z.B. hydraulisch, pneumatisch und/oder
mechanisch.The detachability of the scale layer is due to the
Als Reaktionsmittel 6 kommt eine Vielzahl von Substanzen in Frage.
So können bspw. Metallpulver verwendet werden, welche mindestens
eines der folgenden Metalle enthalten: Si, Al, CaSi oder CaAl. Auch
Nichtmetalle wie z.B. Kohlenstoff können verwendet werden. Ferner
kommen auch Oxide in Frage, z.B. CaO, SiO2, Al2O3, MgO, MnO, Na2O,
FeO, Fe2O3 oder Fe3O4.A large number of substances can be used as the
Das Reaktionsmittel 6 ist in der Trägersubstanz in einer Konzentration
bis zu 90 Volumen-% vorhanden. Pro Quadratmeter zu behandelnder
Bandoberfläche werden ca. 1 bis 2 Liter des unverdünnten
Reaktionsmittels 6 benötigt. The
Abschließend sei noch erwähnt, daß das Reaktionsmittel 6 nicht
unbedingt vor dem Tunnelofen 7 auf die Bramme 2 aufgebracht werden
muß. Das Reaktionsmittel 6 könnte z.B. auch erst im Tunnelofen 7
oder beim Entzundern selbst auf die Bramme 2 aufgebracht werden. Finally, it should be mentioned that the
