Abstract

A continuous casting mold for producing polygonal steel profiles by continuous casting by the curved-mold method, comprises individual plates defining the sides of the molds. The four plates are provided with recesses at their extremities which form abutting joint edges and the edges are held flush with one another by shims inserted between opposing surfaces of the plates at the corners thereof. One pair of plates is provided with radius or bevels so that the cross section of the interior of the mold is octogonal. According to the invention, moreover, the chamfered or bevelled surfaces and the surfaces between them are machined and a corresponding insertion shim is provided to insure that the edges are flush with one another.

Description

Die vorliegende Erfindung betrifft eine zum Bogenstranggiessen von Mehreck-Stahlprofilen geeignete Stranggiesskokille, insbesondere eine aus Einzelplatten zusammengesetzte Plattenkokille, sowie ein Verfahren zum Nachbearbeiten ihrer Innenflächen, im Hinblick auf die Rückstellung des Innenprofils auf Urmass.The present invention relates to a continuous casting mold suitable for the continuous casting of polygonal steel profiles, in particular a plate mold composed of individual plates, and to a method for reworking its inner surfaces with a view to restoring the inner profile to its original size.

Plattenkokillen für das Bogenstranggiessen von Brammen, von Quadrat-, Rechteck- und generell Mehreckprofilen sollen eine gewisse Biegung in Giessrichtung aufweisen, um Biegespannungen in der noch dünnen verfestigten Schale des aus der Kokille austretenden Stranges zu vermeiden. Ausserdem ist es günstig, eine Verjüngung des Kokillenquerschnittes entsprechend der Schrumpfung des abkühlenden Giessgutes vorzusehen, um den Kontakt zwischen der Strangschale und der Kokillen-Innenwand über die gesamte Kokillenlänge zu gewährleisten. Weiter ist es erwünscht, die Ecken des Kokillenquerschnittes angefast oder abgerundet zu gestalten, um Kantenspannungen am Giesstrang zu vermeiden oder zumindest zu verringern.Plate molds for the continuous sheet casting of slabs, square, rectangular and generally polygonal profiles should have a certain bend in the casting direction in order to avoid bending stresses in the still thin, solidified shell of the strand emerging from the mold. In addition, it is expedient to provide a tapering of the mold cross section in accordance with the shrinkage of the cooling casting material, in order to ensure the contact between the strand shell and the mold inner wall over the entire mold length. It is also desirable to chamfer or round the corners of the mold cross section in order to avoid or at least reduce edge tensions on the casting strand.

Bei Verschleiss, Riefenbildung und Verlust der Konizität müssen die Innenflächen der Stranggiesskokille nachbearbeitet werden.In the event of wear, scoring and loss of taper, the inner surfaces of the continuous casting mold must be reworked.

Dies erfordert bei Plattenkokillen, die eine komplexe Geometrie gemäss den oben erwähnten Kriterien aufweisen, eine sorgfältig durchzuführende Massarbeit, die jedoch infolge des Materialabtrages notgedrungen zu einer Vergrösserung des Kokillenquerschnittes und damit auch des Strangquerschnittes führt.In the case of plate molds which have a complex geometry according to the criteria mentioned above, this requires careful custom-made work, which, however, inevitably leads to an enlargement of the mold cross-section and thus of the strand cross-section as a result of the material removal.

Will man diesen Querschnitt jedoch auf Urmass halten, so gibt es lediglich zwei Alternativen. Entweder zögert man den Verschleiss so weit wie möglich hinaus indem man die Innenflächen der Kokillenplatten vor Verschleiss schützt und hierfür einen Schutzüberzug aus verschleissfestem Material, bspw. aus Zirkonoxyd vorsieht, oder man verzichtet auf einen solchen Schutz und zieht ein häufigeres Verschrotten billigerer Kokillen vor.However, if you want to keep this cross-section at primal measure, there are only two alternatives. Either one delays the wear as much as possible by protecting the inner surfaces of the mold plates from wear and providing a protective cover made of wear-resistant material, e.g. zirconium oxide, or by doing without such protection and preferring more frequent scraping of cheaper molds.

Weder der Verlust des Urmasses, noch die Verwendung mehr oder weniger teurer Wegwerfkokillen dürften im Interesse des Benutzers liegen.Neither the loss of the original size nor the use of more or less expensive disposable molds should be in the interest of the user.

Der vorliegenden Erfindung ist somit die Aufgabe zugrundegelegt eine Plattenkokille zu entwickeln, die einerseits den geometrischen Kriterien für das Bogenstranggiessen gerecht wird und die andererseits so gestaltet ist, dass eine Rückstellung des Kokillenquerschnittes auf Urmass auch nach mehrmaligem Nachbearbeiten möglich ist. Eine weitere Aufgabe bestand darin, ein geeignetes Verfahren zu einer solchen Nachbearbeitung zu entwickeln.The present invention is therefore based on the object of developing a plate mold which, on the one hand, meets the geometric criteria for continuous sheet casting and which, on the other hand, is designed in such a way that the mold cross section can be reset to its original size even after repeated reworking. Another task was to develop a suitable method for such post-processing.

Diese Ziele werden erreicht durch die erfindungsgemässe Stranggiesskokille, die dadurch gekennzeichnet ist, dass vier Einzelplatten an ihren Extremitäten Aussparungen aufweisen, die beim Aneinanderfügen der Platten ineinandergreifen und die Stosskanten mittels in die Aussparungen eingeführter Passbleche auf gleiche Höhe eingestellt sind, wobei die Innenflächen zweier gegenüberliegender Platten an den Extremitäten Fasen aufweisen, so dass sich ein achtkantiger Kokillenquerschnitt ergibt.These goals are achieved by the continuous casting mold according to the invention, which is characterized in that four individual plates have recesses on their extremities, which engage when the plates are joined together, and the abutting edges are adjusted to the same height by means of fitting plates inserted into the recesses, the inner surfaces of two opposite plates Have chamfers on the extremities, so that there is an octagonal mold cross-section.

In dieser Kokille können, wie noch erläutert wird, die Fasen bzw. Radien aufweisenden Platten über die Stossflächen nachgestellt und die mit nicht verschleissenden Stossflächen ausgestatteten Platten durch Passbleche nachgestellt werden.In this mold, as will be explained below, the chamfers or radii plates can be adjusted over the abutting surfaces and the plates equipped with non-wearing abutting surfaces can be adjusted with fitting plates.

In der montierten Kokille können gemäss einer ersten Ausführungsform die Fasen bzw. Radien aufweisenden Platten parallel zur Giessrichtung angeordnet sein. Eine zweite Ausführungsform sieht vor, die Fasen aufweisenden Platten in der montierten Kokille quer zur Giessrichtung anzuordnen.According to a first embodiment, the plates having chamfers or radii can be arranged parallel to the casting direction in the assembled mold. A second embodiment provides for the bevelled plates to be arranged transversely to the casting direction in the installed mold.

Sei es, dass man die eine oder die andere Ausführungsform bevorzugt, so weisen jedenfalls erfindungsgemäss die Innenflächen der in der montierten Kokille quer zur Giessrichtung angeordneten Platten eine dem Giessradius entsprechende Krümmung auf, während die Innenflächen der parallel zur Giessrichtung angeordneten Platten eben sind.Be it that one or the other embodiment is preferred, the inner surfaces of the plates arranged in the mounted mold transversely to the casting direction have a curvature corresponding to the casting radius, while the inner surfaces of the plates arranged parallel to the casting direction are flat.

Weiter weisen die Stossflächen der parallel zur Giessrichtung angeordneten Platten eine dem Giessradius entsprechende Krümmung auf, so dass die Teilfugen der montierten Kokille im gewünschten Sinne gekrümmt verlaufen.Furthermore, the abutting surfaces of the plates arranged parallel to the casting direction have a curvature corresponding to the casting radius, so that the parting joints of the installed mold run in the desired sense.

Die Querschnittverjüngung der Kokille in Giessrichtung wird erreicht durch eine dementsprechende Ausbildung der Stossflächen.The cross-sectional tapering of the mold in the casting direction is achieved by designing the abutting surfaces accordingly.

Wie man feststellt, lassen die recht komplizierten geometrischen Kriterien sich bei der erfindungsgemässen Kokille durch entsprechende Ausbildung lediglich der Stossflächen der einzelnen Platten befriedigen, wobei die Innenflächen keine besondere Ausbildung benötigen.As can be seen, the quite complicated geometric criteria can be satisfied in the mold according to the invention by appropriate training only of the abutting surfaces of the individual plates, the inner surfaces not requiring any special training.

Um die Qualität der Fugen in der montierten Kokille aufrechtzuerhalten genügt es erfindungsgemäss, die Stossflächen der quer zur Giessrichtung angeordneten, keine Fasen aufweisenden Platten mit einem verschleissfesten Ueberzug zu versehen. Die Erklärung hierfür ergibt sich aus dem Verfahren zur Nachbearbeitung der einzelnen Platten, nach der Erfindung.In order to maintain the quality of the joints in the assembled mold, it is sufficient according to the invention to provide the abutting surfaces of the plates which are arranged transversely to the casting direction and have no bevels with a wear-resistant coating. The explanation for this arises from the method for reworking the individual plates, according to the invention.

Das erfindungsgemässe Verfahren ist dadurch gekennzeichnet, dass man an den Fasen aufweisenden Platten von der Innenfläche sowie von der Stossfläche Material um ein Dickenmass (a) und von den Fasen Material um ein Dickenmass (a mal den Kosinus des Fasenwinkels) abträgt, dass man an den Platten ohne Fasen von der Innenfläche Material um ein Dickenmass (b) abträgt und dass man die zwischen den Platten befindlichen Passbleche um das gleiche Mass (b) zurücknimmt. wobei die Masse (a und b) voneinander verschieden sein können.The method according to the invention is characterized in that material is removed from the inner surface and from the butting surface by a thickness dimension (a) and from the chamfer material by a thickness dimension (a times the cosine of the chamfer angle) on the plates having chamfers Remove panels without chamfers from the inner surface of the material by a thickness (b) and that the shims between the panels are taken back by the same amount (b). the masses (a and b) can be different from one another.

Dieses Verfahren gestattet, wie leicht einzusehen ist, ein mehrmaliges Nacharbeiten der Innenflächen der Platten bei gleichzeitiger sich praktisch automatisch ergebender Rückstellung des Kokillenquerschnittes auf Urmass und zwar kann eine Nacharbeitung so oft stattfinden, wie durch die Anwesenheit von Passblechen zwischen den einzelnen Platten noch Raum zum Nachstellen des Abtragemasses zur Verfügung steht.As can easily be seen, this process allows the inner surfaces of the plates to be reworked several times while the mold cross-section is reset automatically to practically the same size, and reworking can take place as often as there is still room for re-adjustment due to the presence of shims between the individual plates of the removal dimension is available.

Angesichts der Gestehungskosten von Plattenkokillen stellen die erfindungsgemässe Kokille, sowie das Verfahren zur Nachbearbeitung einen erheblichen Fortschritt dar.In view of the production costs of plate molds, the mold according to the invention and the method for post-processing represent considerable progress.

Zur Erläuterung der Erfindung dienen die Zeichnungen, in denen Fig. 1 eine perspektive Darstellung des durch eine erfindungsgemässe Plattenkokille begrenzten Innenprofils zeigt; Fig. und Fig.3 zeigen je einen Querschnitt durch eine mögliche Ausführungsform der erfindungsgemässen Kokille, in denen die Fasen tragenden Platten parallel bzw. quer zur Giessrichtung angeordnet sind, während die Fig.2a und 2b, sowie die Fig. 3a und 3b Querschnitte der Grenzzonen zweier Platten darstellen und die mit Hilfe des erfindungsgemässen Verfahrens zu erzielende Rückstellung auf Urmass beim Nacharbeiten veranschaulichen, wobei die Fig. 2a und 3a jeweils den Ur-Zustand und die Fig. 2b und 3b jeweils den Zustand nach der Nachbearbeitung zeigen.The drawings serve to explain the invention, in which FIG. 1 shows a perspective illustration of the inner profile delimited by a plate mold according to the invention; 3 and 3 each show a cross section through a possible embodiment of the mold according to the invention, in which the chamfer-bearing plates are arranged parallel or transversely to the casting direction, while FIGS. 2a and 2b and FIGS. 3a and 3b show cross sections of the Represent boundary zones of two plates and illustrate the resetting to the original size during reworking which can be achieved with the aid of the method according to the invention, FIGS. 2a and 3a each showing the original state and FIGS. 2b and 3b each showing the state after the reworking.

Die Fig. 1 dient in der Hauptsache zur Veranschaulichung der relativ komplexen Geometrie des Innenprofiles, das durch die einzelnen Platten begrenzt ist und zwar erkennt man, dass einerseits der Querschnitt (A ... H) grösser ist als der Querschnitt (A' ... H'), dass also der Kokillenquerschnitt in der Giessrichtung, die durch den Pfeil angedeutet ist, abnimmt ; dass andererseits die Grenzflächen (AHGFF'G'H'A') und (BCDEE'D'C'B') gekrümmt sind, während die Grenzflächen (ABB'A') und (EFF'E') in der senkrechten Ebene Parallel zur Giessrichtung verlaufen und demnach in der Plattenebene selbst nicht gekrümmt sind.1 mainly serves to illustrate the relatively complex geometry of the inner profile, which is delimited by the individual plates, and it can be seen that on the one hand the cross section (A ... H) is larger than the cross section (A '.. . H ') that the mold cross-section decreases in the casting direction, which is indicated by the arrow; that on the other hand the interfaces (AHGFF'G'H'A ') and (BCDEE'D'C'B') are curved, while the interfaces (ABB'A ') and (EFF'E') are parallel to the vertical plane Casting direction run and are therefore not curved in the plate plane itself.

Ferner wird ersichtlich, dass zur Ausbildung der Krümmung der Teilfugen, an den parallel zur Giessrichtung angeordneten Platten lediglich die Stossflächen entsprechend gekrümmt ausgeführt werden müssen und dies unabhängig davon., ob die Fasen tragenden oder nicht tragenden Platten in der Kokille parallel zur Giessrichtung angeordnet sind.Furthermore, it can be seen that in order to form the curvature of the parting joints, only the abutting surfaces on the plates arranged parallel to the casting direction have to be designed accordingly, regardless of whether the chamfer-bearing or non-load-bearing plates in the mold are arranged parallel to the casting direction.

In den Fig. 2 bzw. 3 und den dazugehörigen Fig. 2a, 2b bzw. 3a, 3b wird das erfindungsgemässe Nachbearbeitungs-Verfahren veranschaulicht und zwar für beide Ausführungsformen der erfindungsgemässen Plattenkokille.2 and 3 and the associated FIGS. 2a, 2b and 3a, 3b illustrate the post-processing method according to the invention, specifically for both embodiments of the plate mold according to the invention.

In der Fig. 2a erkennt man eine Platte (1), die gefast ausgeführt ist. von der Innenfläche sowie von der Stossfläche wird Material um ein Mass (a) abgetragen; das von der Fase (10) abzutragende Mass ergibt sich aus a x cosa, wobei a der Fasenwinkel ist. Unabhängig hiervon wird von der Innenfläche der angrenzenden Platte (4) Material um ein Mass (b) abgetragen, was durch Zurücknehmen der Passbleche (50) um genau dieses Mass (b) wieder kompensiert wird. Hierdurch ergibt sich, wie aus der Fig. 2b e.rsicht- lich, wieder das Urmass des Kokillen-Innenraumes.In Fig. 2a you can see a plate (1) which is designed chamfered. Material is removed by a dimension (a) from the inner surface and from the butt surface; the dimension to be removed from the chamfer (10) results from a x cosa, where a is the chamfer angle. Irrespective of this, material is removed from the inner surface of the adjacent plate (4) by a measure (b), which is compensated for by taking back the fitting plates (50) by exactly this measure (b). As can be seen from FIG. 2b, this results in the original size of the mold interior again.

Der gleiche Vorgang wird in den Fig.3, 3a sowie 3d dargestellt.The same process is shown in Figures 3, 3a and 3d.

Es sei abschliessend bemerkt, dass man sich selbstverständlich beim Festsetzen des abzutragenden Masses (b) nicht nur am Ausmass des Verschleissens, sondern auch an den Dickenmassen der einzelnen Passbleche (50) orientiert um ein problemloses Kompensieren der abgetragenen Materialdicke zu ermöglichen.In conclusion, it should be noted that, of course, when determining the amount to be removed (b), not only the extent of wear, but also the thickness of the individual shim plates (50) are used to enable the material thickness removed to be compensated for without any problems.
