Description

Die Erfindung bezieht sich auf eins Stranggußanlage für Vorband, bestehend im wesentlichen aus mehreren, parallel angeordneten Gießeinrichtungen, Kokillen, Bandführungs- und Umlenkeinrichtungen, ferner mit Querteiieinrichtungen zur Unterteilung der Stränge in der Rollgangsebene, sowie mit nachgeschaltetem Nachwärm- oder Heizofen, Entzunderungseinrichtungen, Walzgerüsten, Kühlstrecke und Haspeln, wobei der Heizofen mehrere, parallel angeordnete Auflaufrollgänge entsprechend der Anzahl der Gießstränge aufweist sowie mindestens einen ebenfalls parallelen Ablaufrollgang zur Förderung des Vorbandes zu den nachgeschalteten Aggregaten.The invention relates to a continuous casting plant for preliminary strip, consisting essentially of several, parallel arranged casting devices, molds, belt guiding and deflecting devices, further with cross-dividing devices for dividing the strands in the roller table level, as well as with a subsequent reheating or heating furnace, descaling devices, rolling stands, Cooling section and reels, the heating furnace having a plurality of parallel roller conveyors arranged in accordance with the number of casting strands and at least one likewise parallel roller conveyor for conveying the preliminary strip to the downstream units.

Die wichtigsten Kriterien bei der Auslegung einer Stranggußanlage mit einwandfreier Walztemperaturführung des Vorbandes sind Investitionsaufwand, Wärmeverluste, Platzbedarf sowie Reparatur- und Wartungsfreundlichkeit. Langwierige Bandführungen mit hohen Wärmeverlusten und vielen Umformvorgängen sind sehr kostenaufwendig, insbesondere wegen der Wickelvorgänge und Walzstiche im Bandmanipulationsbereich. Selbst wenn die Wickelvorgänge bei großen Durchmessern erfolgen und somit die Walzstiche entfallen, bleiben diese Verfahren immer noch sehr aufwendig.The most important criteria when designing a continuous casting plant with perfect rolling temperature control of the preliminary strip are investment costs, heat losses, space requirements and ease of repair and maintenance. Lengthy belt guides with high heat losses and many forming processes are very expensive, especially because of the winding processes and roll stitches in the belt manipulation area. Even if the winding processes take place with large diameters and thus the rolling passes are omitted, these processes still remain very complex.

Werden diese Vorgänge langsam durchgeführt, so entstehen zusätzlich weitere Wärmeverluste.If these processes are carried out slowly, additional heat losses occur.

Wärmeverluste sind mit der Isolierfähigkeit der Einzelanlagen sowie dem zeitlichen Aufwand der Prozeßführung verbunden. Bei Einrichtungen, die schlecht isolierbar und nicht beheizbar sind, müssen hohe Arbeitsgeschwindigkeiten angestrebt werden. Das gilt insbesondere für das Umformgerüst zur Verdichtung des Vorbandes, die Coilbox, die Querverfahreinrichtung, den Entcoiler und den Zunderbrecher. Da alle Arbeitsvorgänge mit Wärmeveriusten behaftet sind, die nur mit hohem Investitionsund Energieaufwand ersetzt werden, müssen geringe Prozeßzeiten und kurze Verfahrwege an oberster Stelle stehen. Obwohl der Platzbedarf ein ständiges Problem darstellt, dürfen aber keine Anlagen zusammengestellt werden, die zwar kürzer gebaut werden können, aber dennoch kostenaufwendiger sind.Heat losses are associated with the insulating ability of the individual systems and the time required for the process control. For facilities that are poorly insulated and cannot be heated, high working speeds must be aimed for. This applies in particular to the forming stand for compacting the pre-strip, the coil box, the cross-travel device, the decoiler and the scale breaker. Since all work processes involve heat loss, which can only be replaced with a high investment and energy expenditure, short process times and short travel distances must be the top priority. Although the space requirement is a constant problem, it is not allowed to put together systems that can be built shorter, but are still more expensive.

Aus der DE-A 3 525 457 ist eine mit der vorliegenden Erfindung gattungsgleiche Stranggußanlage für Vorband mit mehreren, parallel angeordneten Gießeinrichtungen, Kokillen, Bandführungs- und Umlenkeinrichtungen bekannt, ferner ausgestattet mit Querteiieinrichtungen zur Unterteilung der Stränge in der Rollgangsebene, sowie mit nachgeschaltetem Nachwärm- oder Heizofen, Entzunderungseinrichtungen, Walzgerüsten, Kühlstrecke und Haspeln, wobei der Heizofen mehrere, parallel angeordnete Auflaufrollgänge entsprechend der Anzahl der Gießstränge aufweist. Bei dieser bekannten Anlage geht es im wesentlichen darum, das Vormaterial über einen oder mehrere Nachwärm-oder Ausgleichsöfen auf Walztemperatur einzustellen und anschließend einer in zwei Gruppen aufgeteilten Fertigstraße zuzuführen, wobei über die Nachwärm- bzw. Ausgleichsöfen keine Angaben gemacht werden.DE-A 3 525 457 discloses a continuous casting installation of the same type with the present invention for supporting strip with a plurality of pouring devices, molds, belt guiding and deflecting devices arranged in parallel, and also equipped with cross-dividing devices for dividing the strands in the roller table level, and with downstream reheating or heating furnace, descaling devices, rolling stands, cooling section and reels, the heating furnace having a plurality of parallel roller conveyors arranged in accordance with the number of casting strands. This known system essentially involves setting the primary material to the rolling temperature via one or more reheating or equalizing furnaces and then feeding it to a finishing train divided into two groups, with no details being given about the reheating or equalizing furnaces.

Auch aus der vorangemeldeten aber nachveröffentlichten EP-A 88 110 925 ist eine Stranggußanlage mit Heizofen als vorbekannt zu entnehmen, wobei allerdings die Rollgangsebenen im Heizofen auf gleicher Ebene mit dem Heizraum liegen. Nachteilig ist hierbei, daß die Rollgänge der höchsten Ofenraumtemperatur ausgesetzt sind.A continuous casting installation with a heating furnace can also be found in the previously reported but subsequently published EP-A 88 110 925, although the roller table levels in the heating furnace are on the same level as the heating room. The disadvantage here is that the roller tables are exposed to the highest furnace temperature.

Es ist Aufgabe der Erfindung, eine Stranggußanlage vorzustellen, mittels derer die genannten Nachteile vermieden und die Schwierigkeiten ausgeräumt werden können. Insbesondere sollen die Rollgänge und deren Antriebe reparatur- und wartungsfreundlich sein und vor hoher Temperatur geschützt werden. Ferner soll eine kurze Bauweise des nachgeschalteten Heizofens realisiert werden und die Anlage mit nur geringen Investitionskosten herstellbar und auch kostengünstig betreibbar sein.It is an object of the invention to present a continuous casting installation by means of which the disadvantages mentioned can be avoided and the difficulties can be eliminated. In particular, the roller tables and their drives should be easy to repair and maintain and should be protected from high temperatures. Furthermore, a short design of the downstream heating furnace is to be realized and the system can be manufactured with only low investment costs and also be operated at low cost.

Die Lösung der gestellten Aufgabe gelingt erfindungsgemäß dadurch, daß der Heizofen Rollgangsebenen und Heizebenen aufweist, wobei die Heizebenen im Heizofen gegenüber den Rollgangsebenen vertikal versetzt sind. Auf diese Weise können mit großem Vorteil doppelt gelagerte Rollen gebaut werden und es ist eine gute Reparatur- und Wartungsmöglichkeit gegeben. Die Motorantriebe für die Rollen können vorteilhaft nach außen verlegt werden.According to the invention, this object is achieved in that the heating oven has roller table levels and heating levels, the heating levels in the heating oven being offset vertically with respect to the roller table levels. In this way, double-bearing rollers can be built with great advantage and there is good repair and maintenance options. The motor drives for the rollers can advantageously be moved to the outside.

Der Heizofen erfaßt mit großem Vorteil im allgemeinen die Speicherkapazität einer Sequenz. Darüber hinaus können die Vorbänder gegebenenfalls auf eine Nebenlinie ausgefördert und abgelegt werden. Die Vorbanddicke kann ein Optimierungskriterium für die gesamte Stranggußanlage sein.The heating furnace generally detects the storage capacity of a sequence with great advantage. In addition, the supporting strips can, if necessary, be conveyed onto a secondary line and deposited. The pre-strip thickness can be an optimization criterion for the entire continuous casting plant.

Bei größeren Vorbandicken von etwa 70 bis 80 mm wird der Aufwand geringer, obwohl ein zusätzliches Gerüst erforderlich wird. Es ist vorgesehen, daß bei einer Zweistranggießanlage im Heizofen der Ablaufrollgang zwischen den beiden Auflaufrollgängen angeordnet ist. Mit dieser Maßnahme können die Investitionskosten für die gesamte Anlage, insbesondere aber für den Heizofen extrem niedrig gehalten werden.The effort is reduced for larger advance strips of around 70 to 80 mm, although an additional scaffold is required. It is envisaged that in a two-strand casting installation in the heating furnace, the run-off roller table is arranged between the two run-on roller tables. With this measure, the investment costs for the entire system, but especially for the heating furnace, can be kept extremely low.

In weiterer Ausgestaltung der Erfindung liegen die Heizebenen im Heizofen gegenüber den Rollgangsebenen höher, wobei wiederum doppelt gelagerte Rollen gebaut werden können und eine gute Reparatur- und Wartungsmöglichkeit gegeben ist. Die Motorantriebe für die Rollen können nach außen verlegt werden. Die Rollen, Rollenlager und Antriebe werden auf besonders einfache Weise nicht den hohen Temperaturen im Heizraum von bis zu 1150 Grad Celsius ausgesetzt.In a further embodiment of the invention, the heating levels in the heating furnace are higher than the roller table levels, it being possible in turn for double-bearing rollers to be built and for good repair and maintenance options. The motor drives for the rollers can be moved outside. The rollers, roller bearings and drives are not particularly easily exposed to the high temperatures in the boiler room of up to 1150 degrees Celsius.

Nach einer weiteren Ausgestaltung der Erfindung ist vorgesehen, daß der Heizofen als Hubbalkenofen ausgebildet und mit Hubvorrichtungen ausgestattet ist. Auf diese Weise wird der Quertransport der Vorbänder sehr einfach und betriebssicher durchgeführt, wobei die Hubeinrichtungen zur Vorbandmanipulation in vertikaler Richtung dienen. Es handelt sich um eine besonders kostengünstige Ausführungsform des Heizofens.According to a further embodiment of the invention, it is provided that the heating furnace is designed as a walking beam furnace and is equipped with lifting devices. In this way, the transverse transport of the pre-strips is carried out very easily and reliably, the lifting devices being used for manipulation of the pre-strips in the vertical direction. It is a particularly inexpensive embodiment of the heating furnace.

Weitere Einzelheiten, Merkmale und Vorteile der Erfindung ergeben sich aus der nachstehenden Erläuterung eines in den Zeichnungen schematisch dargestellten Ausführungsbeispieles.Further details, features and advantages of the invention result from the following explanation of an exemplary embodiment shown schematically in the drawings.

Es zeigen:

  • Fig. 1 eine Zweistranggießanlage mit erfindungsgemäßem Heizofen in schematischer Draufsicht,
  • Fig. 2 Teilschnitt durch einen erfindungsgemäßen Heizofen mit versetzten Ebenen.
Show it:
  • 1 shows a two-strand caster with a heating furnace according to the invention in a schematic plan view
  • Fig. 2 partial section through a heating furnace according to the invention with offset levels.

Figur 1 zeigt eine Zweistrang-Gießanlage in der erfindungsgemäß günstigen kurzen Bauform. Der guten Übersichtlichkeit halber sind die zwei Gießeinrichtungen, Kokillen, Bandführungs-, Umlenk- und Querteileinrichtungen nicht dargestellt, sondern nur der Heizofen (1) mit nachgeschaltetem Zunderbrecher (2), den Walzgerüsten (3), der Kühlstrecke (4) sowie den Haspeln (5). Im Heizofen (1) befinden sich zwei, die Vorbandstränge (I, II) aufnehmenden Auflauf- oder Anförderrollgänge (10, 11) sowie der Ablauf- bzw. Abförderrollgang (12). Die Gesamtlänge des Ofens (1) entspricht der Vorbandlänge der zwei Stränge (I, II), wodurch sich die Baulänge des Ofens (1) gegenüber ansonsten vierfacher Vorbandlänge auf das Mindestmaß von einer Vorbandlänge reduziert. Die Temperaturverteilung im Ofen (1) entspricht optimal den Walzbedingungen der nachgeschalteten Gerüste (3).FIG. 1 shows a two-strand casting installation in the short design which is favorable according to the invention. For the sake of clarity, the two pouring devices, molds, belt guiding, deflecting and transverse dividing devices are not shown, but only the heating furnace (1) with a downstream scale breaker (2), the rolling stands (3), the cooling section (4) and the reels ( 5). In the heating furnace (1) there are two overrun or feed roller tables (10, 11) and the outfeed or discharge roller table (12) that accommodate the pre-strip strands (I, II). The total length of the furnace (1) corresponds to the pre-strip length of the two strands (I, II), whereby the overall length of the furnace (1) is reduced to the minimum of one pre-strip length compared to four times the pre-strip length. The temperature distribution in the furnace (1) corresponds optimally to the rolling conditions of the downstream stands (3).

Figur 2 zeigt einen schematisierten Querschnitt durch einen erfindungsgemäßen Hubbalkenofen (1). Durch Höherlegung der Heizebenen (13, 14) wird jeder Rollgang (10, 11, 12) beiderseits frei zugänglich, wodurch doppelt gelagerte Rollen gebaut werden können und eine gute Reparatur- und Wartungsmöglichkeit gegeben ist. Die Motorantriebe (M) für die Rollen können auf diese Weise nach außen verlegt werden.Figure 2 shows a schematic cross section through a walking beam furnace (1) according to the invention. By raising the heating levels (13, 14) each roller table (10, 11, 12) is freely accessible on both sides, which means that double-bearing rollers can be built and there is good repair and maintenance options. In this way, the motor drives (M) for the rollers can be moved to the outside.

Die Vorbandmanipulation in vertikaler Richtung erfolgt über Hubvorrichtungen (20, 21, 22) und quer zur Längsförderrichtung mittels bekannter Hubbalkensysteme (nicht dargestellt). Die von den Gießeinrichtungen (I) und (11) parallel erzeugten Vorbänder werden von den zugehörigen Auflaufrollgängen (10, 11) aufgenommen, von den Hubvorrichtungen (20, 21) angehoben und mittels der nicht gezeigten Querfördereinrichtungen, z. B. Hubbalkensystemen, auf die Heizebenen (13 bzw. 14) befördert und abgelegt. Nach der Wärmebehandlung erfolgt die Abförderung und Übergabe von der Hubeinrichtung (22) auf den Ablaufrollgang (12) und von dort aus zur Breitbandstraße (2, 3, 4, 5). Statt der aufwendigen Rollgänge (10, 11, 12) können eventuell auch preiswerte Hubbalkensysteme zur Längsförderung im Ofen (1) eingesetzt werden.The pre-strip manipulation in the vertical direction takes place via lifting devices (20, 21, 22) and transversely to the longitudinal conveying direction by means of known walking beam systems (not shown). The pre-strips produced in parallel by the casting devices (I) and (11) are taken up by the associated overrun roller tables (10, 11), raised by the lifting devices (20, 21) and by means of the transverse conveyor devices, not shown, for. B. walking beam systems on the heating levels (13 and 14) transported and stored. After the heat treatment, it is removed and transferred from the lifting device (22) to the roller table (12) and from there to the broadband line (2, 3, 4, 5). Instead of the complex roller tables (10, 11, 12), inexpensive walking beam systems can also be used for longitudinal conveying in the oven (1).

Die erfindungsgemäßen Maßnahmen sind nicht auf das in den Zeichnungsfiguren dargestellte Ausführungsbeispiel beschränkt. So kann beispielsweise, ohne den Rahmen der Erfindung zu verlassen, der Heizofen beliebige Querverfahreinrichtungen aufweisen. Die jeweilige konstruktive Ausgestaltung ist in Anpassung an den speziellen Einsatzzweck dem Fachmann anheimgestellt.The measures according to the invention are not limited to the exemplary embodiment shown in the drawing figures. For example, without leaving the scope of the invention, the heating furnace can have any transverse movement devices. The respective constructive design is left to the expert in adaptation to the special purpose.
