Abstract

A method for rolling finished sections from a preliminary section (section blank) by means of an arrangement of roll stands which comprises a first universal stand on the entry side, a second universal stand on the exit side and an edger arranged between these universal stands. An edger is arranged ahead of the rolling group. The preliminary section comes from a continuous casting device and has, at both ends of a web, thickened portions corresponding to the subsequent finished profile. The dimensions of the preliminary section are matched in such a way to the web height, web thickness and/or flange width of the finished section to be rolled that this preliminary section is introduced directly into the first universal stand and can then be rolled to give the finished section with the specified dimensions or, to obtain different dimensions deviating from the original specification, the web-like portion and/or the flange-like thickened portions of the preliminary section are, before the preliminary section is introduced into the first universal roll stand, subjected to reduction rolling in a rolling line (W1) with a free outlet extending parallel to the rolling line (W2) of the arrangement of roll stands (U1, SG, U2), and the preliminary section is then displaced transversely into a position directly in front of the compact rolling group (U1, SG, U2) and introduced into the latter. <IMAGE>

Description

Die Erfindung bezieht sich auf ein Verfahren zum Walzen von Fertigprofilen aus einem Vorprofil mittels einer, im Reversierbetrieb arbeitenden Walzgerüst-Anordnung, die eine Kompakt-Walzgruppe bildet, betehend aus einem eingangsseitigen ersten Universalgerüst, einem ausgangsseitigen zweiten Universalgerüst und einem, zwischen diesen Universalgerüsten angeordnetem Stauchgerüst, wobei der Kompakt-Walzgruppe ein Stauchgerüst vorgeordnet ist, und wobei das Vorprofil ein aus einer Stranggußeinrichtung kommendes Profil ist, das beidendig eines Steges dem späteren Fertigprofil entsprechende Verstärkungen aufweist, und die Abmessungen des Vorprofils auf vorgegebene Abmasse, wie Steghöhe, Stegdicke und/oder Flanschenbreite des zu walzenden Fertigprofils so abgestimmt sind, daß dieses Vorprofil entweder direkt in das erste Universalgerüst der Kompakt-Walzgruppe eingeführt und dann in dieser zu dem Fertigprofil mit den vorgegebenen Abmaßen fertig walzbar ist oder der stegartige Abschnitt und/oder die flanschartigen Verdickungen des Vorprofils zur Erzielung von anderen, von der ursprünglichen Vorgabe der Steghöhe, Stegdicke und/oder der Flanschenbreite abweisenden Abmaßen des in der Kompakt-Gruppe fertig zu walzenden Fertigprofils vor der Einführung des Vorprofils in das erste Universalgerüst der Kompakt-Walzgruppe in einer der Kompakt-Walzgruppe unmittelbar vorgeordneten Walzeinrichtung reduzierend walzverformt werden.The invention relates to a method for rolling finished profiles from a preliminary profile by means of a roll stand arrangement operating in reversing mode, which forms a compact roll group, consisting of an input-side first universal stand, an output-side second universal stand and a compression stand arranged between these universal stands , wherein the compact rolling group is preceded by a compression frame, and wherein the preliminary profile is a profile coming from a continuous casting device, which has reinforcements corresponding to the later finished profile on both ends of a web, and the dimensions of the preliminary profile to predetermined dimensions, such as web height, web thickness and / or Flange width of the finished profile to be rolled are adjusted so that this preliminary profile is either inserted directly into the first universal stand of the compact rolling group and then can be finished rolled into the finished profile with the specified dimensions, or the web-like section nitt and / or the flange-like thickening of the pre-profile to achieve other dimensions of the finished profile to be rolled in the compact group that reject the original specification of the web height, web thickness and / or the flange width before the pre-profile is introduced into the first universal stand of the compact - Roll forming in a rolling device immediately upstream of the compact rolling group.

Ausgehend von der Erkenntnis, daß ein aus einer Stranggußeinrichtung kommendes, direkt der Kompakt-Walzgruppe zugeführtes Vorprofil nur eine begrenzte Anzahl von daraus zu walzenden Fertigprofilen unterschiedlicher Abmessungen zuläßt wurde bereits vorgeschlagen (EP-A-265 757) Fertigprofile mit bedeutend größeren Endabmessungsunterschieden aus einem einzigen, unveränderten Stranggußausgangsprofil in ein und derselben Kompakt-Walzgruppe dadurch zu walzen, daß dieses Vorprofil in einem der Kompakt-Walzgruppe unmittelbar vorgeordneten Stauchgerüst z. B. durch Beaufschlagung des stegartigen Abschnitts bzw. der flanschartigen Verstärkungen des Vorprofils reduzierend walzverformt und dann in die Kompakt-Walzgruppe eingebracht wurde. Hierdurch ließ sich der stegartige Abschnitt des Vorprofils entweder durch Stauchen verkürzen oder auch, gegebenenfalls unter Einbeziehung von fließbaren Verstärkungen verlängern und auch gegebenenfalls die Breite der flanschartigen Verstärkungen reduzieren. Die dem Stauchgerüst unmittelbar nachgeordnete Kompakt-Walzgruppe konnte bei diesem bekannten Verfahren teilweise zu der reduzierenden Verformung des Vorprofils herangezogen werden z. B. zur anpassenden Beaufschlagung der Flanschen dieses Vorprofils.Based on the knowledge that a preliminary profile coming from a continuous casting device and fed directly to the compact rolling group only allows a limited number of finished profiles of different dimensions to be rolled therefrom, it has already been proposed (EP-A-265 757) finished profiles with significantly larger final dimension differences from a single one to roll unchanged continuous casting output profile in one and the same compact rolling group in that this preliminary profile in an upstream of the compact rolling group z. B. was reduced by applying pressure to the web-like portion or the flange-like reinforcements of the preliminary profile and then introduced into the compact rolling group. As a result, the web-like section of the pre-profile could either be shortened by upsetting or also, if necessary with the inclusion of flowable reinforcements, and also possibly reduced the width of the flange-like reinforcements. The compact rolling group immediately downstream of the upsetting frame could be used in part in this known method to reduce the deformation of the preliminary profile, e.g. B. for the appropriate loading of the flanges of this preliminary profile.

Nachteilig erwies sich bei der Durchführung des bekannten Verfahrens, daß die Kompaktwalzgruppe während der reduzierenden Walzverformung des Vorprofils nicht für einen Fertigwalzvorgang zur Verfügung stand und dadurch die mit dem Verfahren erreichbare Gesamtleistung der Anlage begrenzt wurde.A disadvantage of the implementation of the known method was that the compact rolling group was not available for a finish-rolling process during the reducing roll deformation of the preliminary profile, and the overall output of the system that could be achieved with the method was thereby limited.

Der Erfindung liegt die Aufgabe zugrunde, das bekannte Verfahren so zu verbessern, daß sich erheblich größere Leistungen und bessere Ausnutzungsgrade der Walzgerüstanordnung erzielen lassen. Diese Aufgabe wird dadurch gelöst, daß die reduzierende Walzverformung des Vorprofils in einer, parallel zur Walzlinie der Kompakt-Walzgruppe verlaufenden Walzlinie mit freiem Auslauf erfolgt und das reduziert verformte Vorprofil in eine Position unmittelbar vor der Kompakt-Walzgruppe quer verschoben, in diese eingebracht wird.The invention has for its object to improve the known method so that significantly greater performance and better levels of utilization of the rolling stand arrangement can be achieved. This object is achieved in that the reducing roll deformation of the preliminary profile takes place in a rolling line running parallel to the rolling line of the compact rolling group with free runout, and the reduced deformed preliminary profile is moved transversely into a position immediately in front of the compact rolling group and is introduced into it.

Mit dieser Verfahrensweise wird erreicht, daß die reduzierende Walzverformung des Vorprofils unabhängig von der Arbeit der Kompaktwalzgruppe erfolgen kann, das heißt, das reduzierte Vorprofil kann in der Kompakt-Walzgruppe zum Fertigprofil gewalzt werden, während bereits in der parallelen Walzlinie die reduzierende Walzverformung des nächsten Vorprofils erfolgt.With this procedure it is achieved that the reducing roll deformation of the preliminary profile can take place independently of the work of the compact rolling group, i.e. the reduced preliminary profile can be rolled into the finished profile in the compact rolling group, while the reducing rolling deformation of the next preliminary profile is already in the parallel rolling line he follows.

Zur Durchführung des erfindungsgemäßen Verfahrens kann in der parallelen Walzlinie eine Walzeinrichtung angeordnet werden, die ein, die flanschartigen Verstärkungen des Vorprofils im Sinne einer Stauchung des stegartigen Abschnittes des Vorprofils beaufschlagendes Vertikalgerüst aufweist; Diesem Vertikalgerüst kann, wie die Erfindung weiter vorsieht, ein, den stegartigen Abschnitt des Vorprofils beaufschlagendes Horizontalgerüst zugeordnet sein. Es besteht auch die Möglichkeit, in der parallelen Walzlinie nur ein solches Horizontalgerüst anzuordnen und diesem ein Universalgerüst zuzuordnen, dessen Walzen sowohl die flanschartigen Verstärkungen als auch den stegartigen Abschnitt des Vorprofils zu beaufschlagen vermögen.To carry out the method according to the invention, a rolling device can be arranged in the parallel rolling line, which has a vertical stand which acts on the flange-like reinforcements of the preliminary profile in the sense of a compression of the web-like section of the preliminary profile; As the invention further provides, this vertical scaffold can be assigned a horizontal scaffold that acts on the web-like section of the preliminary profile. It is also possible to arrange only one such horizontal stand in the parallel rolling line and to assign a universal stand to the latter, the rolls of which can act on both the flange-like reinforcements and the web-like section of the preliminary section.

Wie die Erfindung weiter vorsieht, kann die Walzlinie ein reversierbares Duo-Vorgerüst als Vertikal- oder Horizontalgerüst mit vorzugsweise glatten Walzen aufweisen, dem eine Kantvorrichtung für den Profilstrang nachgeordnet ist. Diese Anordnung bietet die Möglichkeit, mit einem Walzgerüst wahlweise sowohl die flanschartigen Verstärkungen des Vorprofils im Sinne einer Stauchung des flanschartigen Abschnitts als auch den stegartigen Abschnitt beaufschlagen, in dem der Profilstrang nach dem Durchgang durch das Vorgerüst mittels der Kanteinrichtung gekantent und dann reversierend einen weiteren Durchgang unterworfen wird; ggfs. auch wiederholten Durchgängen.As the invention further provides, the rolling line can have a reversible duo roughing stand as a vertical or horizontal stand with preferably smooth rolls, which is followed by an edging device for the profile strand. This arrangement offers the possibility of optionally applying both the flange-like reinforcements of the preliminary profile in the sense of a compression of the flange-like section and the web-like section in which the profile strand is edged by means of the edge device after passing through the roughing stand and then reversing a further passage is subjected; Repeated runs if necessary.

Es kann weiter erfindungsgemäß bei einer Walzgerüst-Anordnung mit einem, hinter der Stranggußeinrichtung angeordneten, der erstenAccording to the invention, it can also be used for a roll stand arrangement with one of the first, arranged behind the continuous casting device

Walzlinie vorgeordneten Wärmofen dem Wärmofen ein Horizontalwalzgerüst für die Vorverformung, insb. der flanschartigen Verstärkungen des gießwarmen Vorprofils vorgeordnet werden. Mit dieser Anordnung wird die Möglichkeit geschaffen den Profilstrang unmittelbar nach verlassen der Stranggußeinrichtung noch in seiner Gießwärme einer Vorverformung zu unterwerfen, um insb. das Volumen der flanschartigen Verstärkungen des Vorprofils bereits zu verkleinern, bevor es in den Wärmofen gelangt, mit der Folge, daß eine bessere Ausnützung des Wärmofens selbst ermöglicht und eine Vergleichmäßigung der Temperaturverteilung in dem Profilquerschnitt erreicht werden.Upstream of the rolling line, the heating furnace is preceded by a horizontal rolling stand for the pre-deformation, in particular the flange-like reinforcements of the warm, pre-cast profile. With this arrangement, the possibility is created of subjecting the profile strand to a preliminary deformation in its casting heat immediately after leaving the continuous casting device, in particular to reduce the volume of the flange-like reinforcements of the preliminary profile before it reaches the heating furnace, with the result that a better utilization of the heating furnace itself and an equalization of the temperature distribution in the profile cross section can be achieved.

Die Erfindung wird anhand der in der Zeichnungen dargestellten Ausführungsbeispiele näher erläutert. In der Zeichnung zeigen:

Figur 2
eine andere Ausbildungsform der Walzenstraße ebenfalls in der Draufsicht in schematischer Draufsicht.
The invention is explained in more detail using the exemplary embodiments shown in the drawings. The drawing shows:
Figure 1
a roller mill in plan view in a schematic representation and
Figure 2
another embodiment of the roller mill also in a top view in a schematic top view.

Wie aus Figur 1 zu ersehen, ist in einer Walzlinie W1 ein Vertikalgerüst VG angeordnet, und in der parallel dazu verlaufenden Walzlinie W2 die Kompakt-Walzgruppe, die aus den Universal-Walzgerüsten U1 und U2 mit einem dazwischen angeordneten Stauchgerüst SG besteht. Zwischen den beiden Walzlinien W1 und W2 ist eine Querförderanlage QF angeordnet. Die aus dem der Walzlinie 1 zugeordneten Wärmofen WO kommenden, nicht dargestellten Strangguß-Vorprofile werden in dem Vertikalgerüst VG in ihrer Steghöhe soweit gestaucht, daß ihr Kammermaß dem Kammermaß der Universalgerüste U1 und U2 der Kompakt-Walzgruppe in der parallelen Walzlinie W2 angepaßt ist. Praktische Versuche zeigten, daß z. B. Stauchungen der Steghöhe von sechzig mm pro Stich im Vertikalgerüst VG möglich sind und bereits bei fünf Stichen eine Reduzierung der Steghöhe von 300 mm erreicht werden kann. Das Vertikalgerüst VG bedarf dabei nur eines Kalibers und die entstehenden kurzen Auswalzlängen erlauben es den Abstand zwischen dem Vertikalgerüst VG und dem ersten Universal-Walzgerüst U1 der Kompakt-Walzgruppe U1, SG, U2 entsprechend kurz zu bemessen.As can be seen from FIG. 1, a vertical stand VG is arranged in a rolling line W1, and the compact rolling group, which consists of the universal rolling stands U1 and U2 with an upsetting stand SG arranged in between, is arranged in the parallel rolling line W2. A cross conveyor QF is arranged between the two rolling lines W1 and W2. The non-illustrated continuous casting pre-profiles coming from the heating furnace WO assigned to the rolling line 1 are compressed in their vertical height in the vertical stand VG to such an extent that their chamber dimensions are adapted to the chamber dimensions of the universal stands U1 and U2 of the compact rolling group in the parallel rolling line W2. Practical tests have shown that e.g. B. Compression of the web height of sixty mm per stitch in the vertical scaffold VG are possible and a reduction of the web height of 300 mm can be achieved with five stitches. The vertical stand VG requires only one caliber and the resulting short rolling lengths allow the distance between the vertical stand VG and the first universal rolling stand U1 of the compact rolling group U1, SG, U2 to be measured accordingly short.

Die Anordnung der Walzlinien W1 und W2 in Fig. 2 entspricht der nach Figur 1; ebenso die der Kompakt-Walzgruppe U1, SG, U2 und des Querförderers QF. Dem Vertikalgerüst VG in der Walzlinie W1 ist hier lediglich ein Horizontalgerüst HG nachgeordnet. Dieses Horizontalgerüst HG erlaubt auch, ggfs. zusätzlich eine Beaufschlagung des stegartigen Abschnitts des Vorprofils und ermöglicht dadurch die Erzielung eines günstigeren Steg-/Flanschverhältnisses des Vorprofils für den Eingang in die Kompaktwalzgruppe U1, SG, U2. Da hier die Möglichkeit besteht, die Höhe der flanschartigen Verstärkung des Vorprofils im letzten Stich durch das Horizontalgerüst KG zu reduzieren, kann die entsprechende Reduzierung in der Kompakt-Walzgruppe durch das Stauchgerüst SG kleiner und die zugehörige Motorleistung entsprechend reduziert werden.The arrangement of the rolling lines W1 and W2 in Fig. 2 corresponds to that of Figure 1; as well as those of the compact roller group U1, SG, U2 and the cross conveyor QF. The vertical stand VG in the rolling line W1 is only followed by a horizontal stand HG. This horizontal stand HG also allows, if necessary, an additional loading of the web-like section of the preliminary profile and thereby enables a more favorable web / flange ratio of the preliminary profile to be achieved for the entry into the compact rolling group U1, SG, U2. Since it is possible here to reduce the height of the flange-like reinforcement of the preliminary profile in the last pass through the horizontal stand KG, the corresponding reduction in the compact rolling group can be reduced by the edger stand SG and the associated motor output can be reduced accordingly.

Wie weiter aus Fig. 1 zu ersehen, kann in einer anderen Anordnung, bei der das als Duo-Vorgerüst als Vertikal- oder Horizontalgerüst Vertikalgerüst VG vorzugsweise mit glatten Walzen ausgestattet und reversierbar ist, diesem Gerüst die strichpunktiert angedeutete Kantvorrichtung KV nachgeordnet werden, die es dann, wie bereits beschrieben gestattet den aus dem Vertikalgerüst VG austretenden Profilstrang zu kanten und anschließend reversiert einem weiteren Durchgang durch das Vertikalgerüst VG zu unterwerfen. Weiter geht aus Fig. 1 hervor, daß dem Wärmofen WO ein ebenfalls strichpunktiert angedeutetes Horizontalvorgerüst HVG vorgeordnet werden kann, das den aus der, nicht dargestellten Stranggußeinrichtung kommenden, gießwarmen Profilstrang in der bereits erläuterten Weise vorverformt, bevor er in den Wärmofen WO eintritt.As can further be seen from FIG. 1, in a different arrangement, in which the as a double roughing stand as a vertical or horizontal stand Vertical scaffold VG is preferably equipped with smooth rollers and is reversible, the scaffold is followed by the dash-dotted folding device KV, which then, as already described, allows the profile strand emerging from the vertical scaffold VG to be folded and then reversed to be subjected to a further pass through the vertical scaffold VG . 1 that the heating furnace WO can also be preceded by a horizontal roughing stand HVG, also indicated by dash-dotted lines, which pre-deforms the casting-warm profile strand coming from the continuous casting device, not shown, in the manner already explained before it enters the heating furnace WO.
