Description

Die Erfindung betrifft ein Vorprofil zur Formstahlwalzung, welches einen mittleren Steg aufweist, der mit einem Öffnungswinkel von 2 α von 40° - 90° zu je einer seitlichen Verdickung erweitert ist.The invention relates to a pre-profile for shaped steel rolling, which has a central web, which is expanded with an opening angle of 2 α of 40 ° - 90 ° to a lateral thickening.

Die Erfindung betrifft darüber hinaus eine Stranggießanlage zum Gießen des Vorprofils gemäß Oberbegrifft des Anspruch 2.The invention also relates to a continuous casting installation for casting the preliminary profile.

Durch die den nächsten Stand der Technik bildenden US-A-4 805 685 ist eine Kokille und ein darin gegossenes Vorprofil für I-Träger bekannt, wobei ein mittlerer Steg mit einem Öffnungswinkel 2 α von 62° zu seitlichen Verdickungen erweitert ist. Die senkrecht zu den Stegflächen stehenden Endwände bilden eine ebene Fläche. Ein derartiges Profil ist sowohl bezüglich seiner Herstellung als auch bei der Weiterverarbeitung nachteilig. So kühlen die seitlichen Verdickungen innerhalb der Kokille relativ langsam ab, wodurch die Gießgeschwindigkeit begrenzt wird und unterhalb der Kokille eine längere Stützführung für die Verdickungen erforderlich ist. Das bekannte Vorprofil ist nur zur I-Trägerwalzung geeignet, wobei erhebliche Verformungsarbeit anfällt.US-A-4 805 685, which forms the closest prior art, discloses a mold and a pre-profile for I-beams cast therein, a central web having an opening angle 2 α of 62 ° being expanded to form lateral thickenings. The end walls perpendicular to the web surfaces form a flat surface. Such a profile is disadvantageous both in terms of its manufacture and during further processing. The side thickenings inside the mold cool down relatively slowly, which limits the pouring speed and requires a longer support for the thickenings below the mold. The known pre-profile is only suitable for I-beam rolling, with considerable deformation work.

Aufgabe der Erfindung ist eine Verbesserung der Wirtschaftlichkeit bei der Herstellung von Formstahl. Insbesondere soll ein Vorprofil geschaffen werden, daß mit einer geringen Anzahl von Walzstichen, Walzkalibern und Walzeinheiten energiesparend und die Produktivität steigernd zu einer Vielzahl von Fertigformen und Fertigmaßen ausgewalzt werden kann.The object of the invention is to improve the economy in the production of shaped steel. In particular, a preliminary profile is to be created that can be rolled out with a small number of pass passes, roll calibres and rolling units in an energy-saving manner and increase productivity to a large number of finished shapes and finished dimensions.

Die gestellte Aufgabe wird nach der Erfindung bei einem Vorprofil der angegebenen Gattung dadurch gelöst, daß die Stirnseiten der Verdickungen eine in Längsrichtung des Vorprofils verlaufende Vertiefung aufweisen.The object is achieved according to the invention in a pre-profile of the type specified in that the end faces of the thickenings have a recess extending in the longitudinal direction of the pre-profile.

Damit wird ein Vorprofil geschaffen, aus dem überraschenderweise nicht nur I-Träger sondern auch U-Profile und Spundwandprofile mit geringer Verformungsarbeit gewalzt werden können.This creates a preliminary profile from which, surprisingly, not only I beams but also U profiles and sheet piling profiles can be rolled with little deformation work.

Nach einer weiteren Aufgabe der Erfindung soll eine Stranggießanlage zur Herstellung des Vorprofils geschaffen werden, die konstruktiv einfach ist und eine hohe Verfügbarkeit aufweist. Die Stranggießanlage soll insbesondere geeignet sein, die Vorprofile mit wenigen Kokillen zu gießen.According to a further object of the invention, a continuous casting plant for producing the preliminary profile is to be created which is structurally simple and has high availability. The continuous caster should be particularly suitable for casting the preliminary profiles with a few molds.

Diese Aufgabe wird bei einer Stranggießanlage zum Gießen eines Vorprofiles zur Formstahlwalzung, wobei eine Kokille aus zwei Seitenwänden und zwei Stirnwänden besteht, jede Seitenwand eine Stegfläche, zwei in einem Winkel von 20° - 45° zur Stegfläche geneigte Erweiterungsflächen und zwei Verdickungsflächen aufweist und der Kokille eine Strangführung nachgeordnet ist, dadurch gelöst, daß zwischen gegenüberstehenden Verdickungsflächen je eine mit einem Vorsprung in den Formraum versehene Stirnwand verstellbar angeordnet sind.This task is carried out in a continuous caster for casting a pre-profile for form steel rolling, wherein a mold consists of two side walls and two end walls, each side wall has a web surface, two extension surfaces inclined at an angle of 20 ° - 45 ° to the web surface and two thickening surfaces and the mold a strand guide is arranged downstream, in that in each case one end wall provided with a protrusion into the molding space is adjustably arranged between opposing thickening surfaces.

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 thus created makes it possible to cast pre-profiles with a crack-free surface and good structure at low cost, which can be rolled into beams, rails, sheet piling and other profiles with a low total number of passes.

Bei einer der Kokille nachgeordneten Strangführung sind vorteilhaft Stegführungsrollen und Endführungsrollen mit den Erweiterungsfühungsrollen in Wechselfolge angeordnet.In a strand guide arranged downstream of the mold, web guide rollers and end guide rollers are advantageously arranged in alternation with the extension guide rollers.

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.

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. This means that several different orders can be cast in a long casting sequence.

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 Stranggießanlag 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 = 30° 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. In the exemplary embodiment, the extension surfaces 4b, 5b run at an angle α = 30 ° to the planes of the web 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 loaded 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 expansion 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 Wechsel folge 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 with the extension guide rollers 12 in alternation.

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 which run perpendicular to the web 1a.

Das gegossene Vorprofil 1 besteht aus dem mittleren Steg 1a, der mit einem Öffnungswinkel 2 α=60° 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 ° 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 long 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.
