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 abge-.: rundet zu gestalten, um Kantenspannungen am Giesstrang zu vermeiden oder zumindest zu verringern.Plate molds "for the continuous casting of slabs, of 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 advantageous to taper the Provide 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 inner wall of the mold over the entire length of the mold to avoid or at least reduce.
Bei Verschleiss, Rie.fenbildung und Verlust der Konizität müsse die Innenflächen der Stranggiesskokille nachbearbeitet werden.In the event of wear, tearing and loss of taper, the inner surfaces of the continuous casting mold must be reworked.
Dies erfordert bei Plattenkokillen; die eine komplexe Geometri gemäss den oben erwähnten Kriterien aufweisen, eine sorgfälti durchzuführende Massarbeit, die jedoch infolge des Materialabtrages notgedrungen zu einer Vergrösserung des Kokillenquerschnittes und damit auch des Strangquerschnittes führt.This requires with plate molds; which have a complex geometry in accordance with the criteria mentioned above, a custom work to be carried out carefully, but which, due to the material removal, necessarily leads to an enlargement of the mold cross section and thus also of the strand cross section.
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 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 eingeführterPassbleche 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 cutouts 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 cutouts, the inner surfaces of two plates lying opposite one another 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 Ausfüh- rungsform 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.In the assembled mold, the chamfers or radii having plates may be arranged parallel to the casting direction according to a first form from leadership. A second embodiment provides for the chamfered plates to be arranged transversely to the casting direction in the assembled 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 assembled 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.According to the invention, in order to maintain the quality of the joints in the assembled mold, it is sufficient for the abutting surfaces of the surfaces arranged transversely to the casting direction to have no chamfers Provide plates 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 Plates without chamfering material from the inner surface by a measure of thickness (b) and that the shims between the plates are taken back by the same measure (b), whereby the measures (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 zwarAs can easily be seen, this method allows the inner surfaces of the plates to be reworked several times, while at the same time the mold cross section is automatically reset to its original size
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.Reworking can take place as often as there is still space for adjusting the removal dimensions due to the presence of shims between the individual plates.
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 significant progress.
Zur Erläuterung der Erfindung dienen die Zeichnungen, in denen Fig. 1 eine perspektive Darstellung des durch eine erfindungsgemässe Plattenkokille begrenzten Innenprofils zeigt; Fig. 2 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; FIGS. 2 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 represent the boundary zones of two plates and those with the help of the The process of resetting to the original dimension during reworking is illustrated, with 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.The main purpose of Fig. 1 is to illustrate. The relatively complex geometry of the inner profile, which is limited by the individual plates, shows that on the one hand the cross section (A ... H) is larger than the cross section (A '... H'), i.e. the mold cross section in the casting direction, which is indicated by the arrow, decreases; 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 in the vertical plane run to the casting direction 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.It can also 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 are arranged in the mold 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 Fig. 2a; 2b and 3a, 3b, the post-processing method according to the invention is illustrated, 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 cos α, wobei α 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 ersichtlich, wieder das Urmass ües 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 cos α, where α 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). Through this. as can be seen from FIG. 2b, the original dimension of the mold interior again results.
Der gleiche Vorgang wird in den Fig. 3, 3a sowie 3b dargestellt.The same process is shown in Figs. 3, 3a and 3b.
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, when setting the amount to be removed (b), it is of course not only based on the extent of wear, but also on the thicknesses of the individual shims (50) to enable the material thickness removed to be compensated for without any problems.
