Description

Die Erfindung betrifft eine Stranggießanlage zum Gießen von Vorprofilen zur Formstahlwalzung, die aus einer gekühlten Kokille und dieser nachgeordneten Strangführung besteht, wobei zwei Seitenwände der Kokille je eine Stegfläche, zwei Erweiterungsflächen und zwei parallele Verstellflächen auf­weisen, zwischen denen Stirnwände verstellbar angeordnet sind.The invention relates to a continuous casting plant for casting pre-profiles for steel forming, which consists of a cooled mold and this downstream strand guide, two side walls of the mold each having a land surface, two extension surfaces and two parallel adjustment surfaces, between which end walls are arranged adjustable.

Durch die DE-A1 2 218 408 ist eine Kokille zum Gießen von Vorprofilen zur Trägerwalzung bekannt, wobei zur Anpassung des Vorprofils an der Fertigprofil die Stirnwände zwischen parallelen Verstellflächen der Seitenwände durch Spindeln verstellt werden können. Bei dieser Kokille stehen die Er­weiterungsflächen in einem Winkel von 75o zu den Stegflä­chenebenen. Eine derartige Kokille hat den Nachteil, daß nur Vorprofile eines kleinen Abmessungsbereichs der Trägerwal­zung gegossen werden können. Ein weiterer Nachteil dieser Kokille besteht darin, daß es im Formraum zu einer Verklem­mung des Stranges infolge der Strangschrumpfung kommen kann.DE-A1 2 218 408 discloses a mold for casting pre-profiles for carrier rolling, the end walls between parallel adjustment surfaces of the side walls being able to be adjusted by spindles to adapt the pre-profile to the finished profile. With this mold, the extension surfaces are at an angle of 75 o to the web surface levels. Such a mold has the disadvantage that only preliminary profiles of a small dimensional range of the carrier roll can be cast. Another disadvantage of this mold is that the strand can become jammed in the molding space as a result of the strand shrinkage.

Ziel der Erfindung ist eine Verbesserung der Wirtschaftlich­keit bei der Herstellung von Formstahl. Aufgabe der Erfin­dung ist die Schaffung einer Stranggießanlage zur Herstel­lung von Vorprofilen für die Formstahlwalzung, die konstruk­tiv einfach ist und eine hohe Verfügbarkeit aufweist. Die Stranggießanlage soll insbesondere geeignet sein, mit wenigen Kokillen Voprofile zu gießen, die mit einer geringen Anzahl von Walzstichen, Walzkalibern und Walzeinheiten energiespa­rend und die Produktivität steigernd zu einer Vielzahl von Fertigformen und Fertigmaßen ausgewalzt werden können.The aim of the invention is to improve the economy in the production of shaped steel. The object of the invention is to provide a continuous casting plant for the production of pre-profiles for shaped steel rolling, which is structurally simple and has high availability. The continuous caster should be particularly suitable for casting Voprofile with just a few molds, which can be rolled out to save energy with a small number of pass passes, roll calibres and rolling units and increase productivity to a large number of finished shapes and finished dimensions.

Die gestellte Aufgabe wird nach der Erfindung dadurch ge­löst, daß die Erweiterungsflächen in einem Winkel α von 20 bis 45o zur Stegflächenebene geneigt sind, den Stegflächen, Erweiterungsflächen und Verstellflächen Strangführungsrollen fluchtend nachgeordnet sind und den mit einem Vorsprung in den Formraum versehenen, verstellbaren Stirnwänden gleich­sinnig verstellbare Führungselemente nachgeordnet sind.The object is achieved according to the invention in that the extension surfaces are inclined at an angle α of 20 to 45 o to the plane of the web surface, the web surfaces, extension surfaces and adjustment surfaces are arranged in line with guide rollers and the adjustable end walls provided with a projection in the mold space adjustable guide elements are subordinate.

Die so geschaffene Stranggießanlage gestattet es, mit weni­gen Kokillen kostengünstig Vorprofile mit rißfreier Ober­fläche und gutem Gefüge zu gießen, die mit geringer Gesamt­stichzahl zu Trägern, Schienen, Spundwänden und anderen Profilen ausgewalzt werden können.The continuous caster created in this way allows low-cost casting of pre-profiles with a crack-free surface and good structure, which can be rolled into beams, rails, sheet piling and other profiles with a low total number of passes.

Ein besonderer Vorteil wird darin gesehen, daß die den Stirnwänden nachgeordneten Führungselemente Gleitflächen für die Vorprofilstirnseiten aufweisen.A particular advantage is seen in the fact that the guide elements arranged downstream of the end walls have sliding surfaces for the front profile end faces.

Gemäß einem weiteren Merkmal der Erfindung sind die Stegfüh­rungsrollen und Endführungsrollen mit den Erweiterungsfüh­rungsrollen in Wechselfolge angeordnet.According to a further feature of the invention, the web guide rollers and end guide rollers are arranged in alternation with the extension guide rollers.

Bei einem Verfahren zum Betrieb einer Stranggießanlage wer­den die Stirnwände der Stranggießkokille und die den Stirn­wänden nachgeordneten Strangführungselemente zur Verän­derung des Profils der Verdickungen während des Gießbetrie­bes verstellt. Dadurch können mehrere unterschiedliche Auf­träge in einer langen Gießsequenz gegossen werden.In a method for operating a continuous casting plant, the end walls of the continuous casting mold and the strand guide elements arranged downstream of the end walls are adjusted to change the profile of the thickenings during the casting operation. As a result, several different orders can be cast in one long casting sequence.

Bei dem gegossenen Profil zur Formstahlwalzung ist ein mitt­lerer Steg mit einem Öffnungswinkel von 40 bis 90o zu je einer seitlichen Verdickung erweitert. Die Stirnseiten der Verdickungen weisen eine Vertiefung auf. Ein wesentlicher Vorteil eines derartigen Profils ist es, daß eine Zentrie­rung bereits im ersten Walzenstich gegeben ist.In the case of the cast profile for forming steel rolling, a central web with an opening angle of 40 to 90 o is expanded to form a lateral thickening. The end faces of the thickenings have a recess. A major advantage of such a profile is that it is already centered in the first roll pass.

Das gegossene Vorprofil wird zum Warmeinsatz in einem nach­folgenden Fertigwalzwerk zur Erzeugung von Parallelflansch­trägern, U-Profilen, Spundwandprofilen etc. verwendet.The cast pre-profile is used for hot use in a subsequent finishing mill to produce parallel flange beams, U-profiles, sheet piling profiles, etc.

Gemäß Fig. 1 besteht eine Stranggießanlage für Vorprofile 1 zur Formstahlwalzung aus einer Kokille 2 mit einer nachge­ordneten Strangführung 3.According to FIG. 1, there is a continuous casting plant for preliminary profiles 1 for forming steel rolling from a mold 2 with a downstream strand guide 3.

Wie aus Fig. 2 zu ersehen, sind zwei Seitenwände 4, 5 an einem Stützrahmen 6 angeordnet. Jede Seitenwand 4, 5 weist eine mittlere Stegfläche 4a, 5a, zwei Erweiterungsflächen 4b, 5b und zwei Verstellflächen 4c, 5c auf. Die Erweite­rungsflächen 4b, 5b verlaufen im Ausführungsbeispiel in einem Winkel α = 30o zu den Ebenen der Stegflächen 4a, 5a. Als seitlicher Abschluß des Kokillenraumes sind zwischen den zueinander parallelen Verstellflächen 4c, 5c Stirnwände 7, 8 angeordnet, die zur Veränderung des Profils durch Spindel­triebe 9 verstellbar sind. Jede Stirnwand 7, 8 weist zum Formraum einen Vorsprung 7a, 8a auf, die im Vorprofil 1 eine Vertiefung 1d bilden. Die Seitenwände 4, 5 und Stirnwände 7, 8 sind mit Kühlkanälen 10 versehen.As can be seen from FIG. 2, two side walls 4, 5 are arranged on a support frame 6. Each side wall 4, 5 has a central web surface 4a, 5a, two extension surfaces 4b, 5b and two adjustment surfaces 4c, 5c. The extension surfaces 4b, 5b extending in the embodiment at an angle α = 30 ° to the planes of the land surfaces 4a, 5a. End walls 7, 8 are arranged between the mutually parallel adjustment surfaces 4c, 5c, which are adjustable by spindle drives 9 to change the profile, as the lateral closure of the mold space. Each end wall 7, 8 has a projection 7a, 8a to the molding space, which form a recess 1d in the preliminary profile 1. The side walls 4, 5 and end walls 7, 8 are provided with cooling channels 10.

Die Kokille 2 wird durch ein oder zwei Gießrohre 19 mit Stahl beschickt. Die Gießrohre 19 sind vorteilhaft in dem von den Erweiterungsflächen 4b, 5b, den Verstellflächen 4c, 5c und den Stirnwänden 7, 8 umschriebenen Raum der Kokille 2 angeordnet und bedürfen keiner Verstellung bei einer Profil­änderung.The mold 2 is fed with steel through one or two pouring tubes 19. The pouring tubes 19 are advantageously arranged in the space of the mold 2 defined by the extension surfaces 4b, 5b, the adjustment surfaces 4c, 5c and the end walls 7, 8 and do not require any adjustment when the profile is changed.

Gemäß den Fig. 1 und 3 besteht die der Kokille 2 nachgeord­nete Strangführung in der Flucht der Kokillenseitenwand 4, 5 aus Stegführungsrollen 11, Erweiterungführungsrollen 12 und Endführungsrollen 13, die innerhalb eines Rahmens 14 gela­gert sind. Wie aus Fig. 1 zu ersehen, sind die Stegführungs­rollen 11 und Endführungsrollen 13 mit den Erweiterungfüh­rungsrollen 12 in Wechselfolge angeordnet.According to FIGS. 1 and 3, the strand guide arranged downstream of the mold 2 is in the alignment of the mold side wall 4, 5 from web guide rollers 11, extension guide rollers 12 and end guide rollers 13, which are mounted within a frame 14. As can be seen from Fig. 1, the web guide rollers 11 and end guide rollers 13 are arranged in alternation with the extension guide rollers 12.

In der Flucht der Stirnwände 7, 8 sind Führungsleisten 15 angeordnet, die durch Spindeltriebe 17 entsprechend der Verstellung der Stirnwände 7, 8 verstellt werden. Die Füh­rungsleisten 16 stützen senkrecht zum Steg 1a verlaufende Stirnflächen 1c des Vorprofils 1.In alignment with the end walls 7, 8, guide strips 15 are arranged, which are adjusted by spindle drives 17 in accordance with the adjustment of the end walls 7, 8. The guide strips 16 support end faces 1c of the preliminary profile 1 that run perpendicular to the web 1a.

Das gegossene Vorprofil 1 besteht aus dem mittleren Steg 1a, der mit einem Öffnungswinkel 2 α =60o zu je einer seitlichen Verdickung 1b erweitert ist. Die Stirnseiten des Vorprofils bestehen aus senkrecht zum Steg 1a verlaufenden Flächen 1c und einer mittleren Vertiefung 1d. Gemäß Fig. 4 können Stirnseiten 1e stumpfwinklig zueinander verlaufen. In diesem Fall kann infolge der Selbststützung in den Randbereichen die Abstützung im Bereich der Vertiefung 1d durch Führungs­kufen 18 erfolgen.The cast pre-profile 1 consists of the central web 1a, which is expanded with an opening angle 2 α = 60 o to a lateral thickening 1b. The end faces of the preliminary profile consist of surfaces 1c running perpendicular to the web 1a and a central recess 1d. 4, end faces 1e can run at an obtuse angle to one another. In this case, as a result of the self-support in the edge regions, the support in the region of the depression 1d can be provided by guide runners 18.

Die beschriebene Stranggießanlage wird wie folgt betrieben: Vor Gießbeginn wird die Kokille 2 in bekannter Weise durch einen Anfahrkopf verschlossen und die Wasserkühlung 10 ein­geschaltet. Danach wird die Kokille 2 durch die Gießrohre 19 gefüllt. Beim Erreichen eines bestimmten Kokillenfüllstandes werden Strangabzug unmd Kokillenoszillation gestartet.The continuous casting installation described is operated as follows: Before casting begins, the mold 2 is closed in a known manner by a start-up head and the water cooling system 10 is switched on. Then the mold 2 is filled through the pouring tubes 19. When a certain mold level is reached, strand withdrawal and mold oscillation are started.

Der aus der Kokille 2 ausgeförderte Vorprofilstrang 1 wird an den Längsseiten durch die Stegführungsrollen 11, Erwei­terungführungsrollen 12 und Endführungsrollen 13 abgestützt. Die stirnseitige Abstützung erfolgt durch die Führungsele­mente 15 bzw. 18.The pre-profile strand 1 discharged from the mold 2 is supported on the longitudinal sides by the web guide rollers 11, extension guide rollers 12 and end guide rollers 13. The end support is provided by the guide elements 15 and 18.

Zur Anpassung des Vorprofils an eine breite Palette von Fertigprofilen können die Stirnwände 7, 8 der Kokille zum Gießen von Vorprofilen 1 mit Verdickungen 1b unterschiedli­cher Größe eingestellt werden. In den Fig. 1 und 2 ist auf der linken Seite eine Einstellung für eine schmale kleine Verdickung und auf der rechten Seite für eine große Ver­dickung dargestellt. Für Sonderprofile kann die Einstellung der Stirnwände 7, 8 auch unterschiedlich sein.To adapt the preliminary profile to a wide range of finished profiles, the end walls 7, 8 of the mold for casting preliminary profiles 1 can be set with thickenings 1b of different sizes. 1 and 2 is a setting for a narrow small on the left Thickening and shown on the right for a large thickening. For special profiles, the setting of the end walls 7, 8 can also be different.

Durch definierte Verstellung der Stirnwände 7, 8 im Sinne einer Vergrößerung und Verkleinerung der Verdickungen 1b und entsprechende Verstellung der Führungselemente 15 bzw. 18 sind lange Gießsequenzen auch bei kleineren Auftragsumfängen möglich.Through defined adjustment of the end walls 7, 8 in the sense of an enlargement and reduction of the thickenings 1b and corresponding adjustment of the guide elements 15 and 18, long casting sequences are possible even with smaller orders.
