Description

Die Erfindung betrifft ein Verfahren zur Sprengkalibrierung einer Kokille gemäß den Merkmalen im Oberbegriff des Patentanspruchs 1.The invention relates to a method for Sprengkalibrierung a mold according to the features in the preamble of claim 1.

Zum Stand der Technik zählen gekühlte Blockkokillen, bei welchen in die Rohrwände parallel zur Längsachse eingebrachte Kühlkanäle vorgesehen sind, die mit einem Kühlmittel beaufschlagt werden können.The prior art includes cooled block molds in which cooling channels introduced into the tube walls parallel to the longitudinal axis are provided, which can be acted upon by a coolant.

Des weiteren sind Rohrkokillen und auch Blockkokillen bekannt, die in den Kokillenwänden vertikale und/oder horizontale Kanäle besitzen, in die Temperaturmeßelemente eingesetzt werden können.Furthermore, tube molds and block molds are known which have vertical and / or horizontal channels in the mold walls, into which temperature measuring elements can be inserted.

Durch den Verschleiß einer Kokille beim Gießen ist es erforderlich, diese nach einer bestimmten Einsatzzeit außer Betrieb zu nehmen und sie zu rekalibrieren. Zu diesem Zweck wird jede Kokille zunächst entchromt und dann ausgeschliffen. Anschließend wird in die Kokille ein Kalibrierdorn eingesetzt, der hinsichtlich seiner Außenabmessungen den Innenabmessungen einer neuen Kokille entspricht. Nach dem Einsetzen des Kalibrierdorns werden die Stirnseiten der Kokille mit Platten dicht verschlossen.Due to the wear of a mold during casting, it is necessary to take it out of operation after a certain period of use and to recalibrate it. For this purpose, each mold is first de-chromed and then ground. Subsequently, a Kalibrierdorn is used in the mold, which corresponds to the outer dimensions of the inner dimensions of a new mold. After inserting the Kalibrierdorns the front sides of the mold are sealed with plates.

Danach wird die Außenfläche der Kokille mit einem geeigneten Sprengstoff belegt und dieser in einem mit einem flüssigen Medium gefüllten Behälter zur Explosion gebracht. Durch die bei der Explosion frei werdende Sprengenergie einerseits und den Gegendruck des flüssigen Mediums andererseits wird die Innenwand der Kokille an den Kalibrierdorn gepreßt. Die Kokille erhält auf diese Weise wieder die erforderliche, für ihren Einsatz im Gießbetrieb exakte Innenkontur.Thereafter, the outer surface of the mold is coated with a suitable explosive and this is brought in a container filled with a liquid medium to explode. Due to the explosive energy released during the explosion on the one hand and the back pressure of the liquid medium on the other hand, the inner wall of the mold is pressed against the Kalibrierdorn. The mold is replaced in this way the required, for their use in the casting operation exact inner contour.

Bei diesem Verfahren ist es aber durch den Verschleiß der Kokille beim Gießen und durch das Ausschleifen nach der Entchromung nicht zu vermeiden, daß Material abgetragen wird und demzufolge die Wanddicke der Kokille bei einer Reparatur reduziert und folglich die Außendimensionen verringert werden.In this method, however, it is unavoidable that the wear of the mold during casting and by the grinding after the dechroming that material is removed and therefore reduces the wall thickness of the mold during repair and thus the outer dimensions are reduced.

Um die Bohrungen in der Kokille, seien sie nun als Kühlkanäle oder als Aufnahmen für Temperaturmeßelemente gedacht, bei der Sprengkalibrierung nicht unzulässig zu verformen, werden vorab in die Bohrungen Füllstücke, vorzugsweise aus Edelstahl, eingebracht, die exakt an die Bohrungen angepaßt sind. Sowohl die Herstellung dieser Füllstücke als auch ihre Montage in die Bohrungen sowie ihre Demontage sind mit einem vergleichsweise hohen Zeit- und Fertigungsaufwand verbunden.To the holes in the mold, they are now intended as cooling channels or as receptacles for Temperaturmeßelemente, not inadmissibly deform in the Sprengkalibrierung, in advance in the holes filler, preferably made of stainless steel, introduced, which are adapted exactly to the holes. Both the production of these patches and their installation in the holes and their disassembly are associated with a relatively high time and manufacturing effort.

Der Erfindung liegt - ausgehend vom Stand der Technik - die Aufgabe zugrunde, ein Verfahren zur Sprengkalibrierung von Kokillen, insbesondere in Form von Rohr- oder Blockkokillen, zu schaffen, das einfacher beherrschbar und mit einem geringeren Aufwand verbunden ist.The invention is - starting from the prior art - the object of the invention to provide a method for Sprengkalibrierung of molds, especially in the form of tubular or block molds, which is easier to handle and associated with less effort.

Diese Aufgabe wird mit den im kennzeichnenden Teil des Patentanspruchs 1 angegebenen Merkmalen gelöst.This object is achieved with the features stated in the characterizing part of patent claim 1.

Die Erfindung beruht auf zwei Maßnahmen, die sich kombinativ ergänzen. Eine Maßnahme ist die Verstärkung der Endbereiche der Kokille vor der Sprengkalibrierung. Dies erfolgt insbesondere durch eine Auftragsschweißung, so daß die Wanddickenverluste durch das Gießen ausgeglichen werden. Um die Bohrungen in der Kokillenwand beim Sprengkalibrieren nicht in unzulässiger Weise zu verformen, werden sie jetzt vor dem Sprengkalibrieren mit einem fließfähigen Material ausgefüllt und endseitig dicht verschlossen. Durch die Verwendung eines fließfähigen Materials kann auf vergleichsweise einfacher Basis auch unterschiedlichen Querschnitten der Bohrungen Rechnung getragen werden. Gezielt auf die Querschnitte der Bohrungen abgestellte Füllstücke sind nicht mehr erforderlich. Der hierfür erforderliche kosten- und zeitintensive Aufwand entfällt vollkommen.The invention is based on two measures that complement each other. One measure is the reinforcement of the end regions of the mold before the explosive calibration. This is done in particular by a build-up welding, so that the wall thickness losses are compensated by the casting. In order not to unduly deform the holes in the mold wall during explosive calibration, they are now filled with a flowable material before the Sprengkalibrieren and tightly sealed end. By using a flowable material, different cross-sections of the bores can be accommodated on a comparatively simple basis. Targeted at the cross sections of the holes parked patches are no longer required. The cost and time-consuming effort required for this completely eliminated.

Die Vorteile der Erfindung machen sich insbesondere dann bemerkbar, wenn es sich bei einer Kokille um eine Rohr- oder Blockkokille aus Kupfer oder einer Kupferlegierung handelt.The advantages of the invention are particularly noticeable when a mold is a tube or block mold made of copper or a copper alloy.

Die Bohrungen können nach Patentanspruch 2 mit einem inkompressiblen Material, wie z.B. Wasser, ausgefüllt werden.The bores may according to claim 2 with an incompressible material, such. Water, to be filled.

Denkbar ist es aber auch, daß die Bohrungen entsprechend Patentanspruch 3 mit einem Schüttgut ausgefüllt werden. Hierbei steht die Kompressibilität des Schüttguts im Zusammenhang mit dessen Porenvolumen. Je höher die Verdichtung des Schüttguts und je feiner die Körnung ist, desto geringer ist das Porenvolumen des Schüttguts und desto höher die Festigkeit.But it is also conceivable that the holes are filled according to claim 3 with a bulk material. Here, the compressibility of the bulk material is related to its pore volume. The higher the densification of the bulk material and the finer the grain, the lower the pore volume of the bulk material and the higher the strength.

Eine weitere Ausführungsform des erfindungsgemäßen Verfahrens besteht darin, daß nach Patentanspruch 4 die Bohrungen mit einer Mischung aus einem inkompressiblen Material und einem Schüttgut ausgefüllt werden.A further embodiment of the method according to the invention is that according to claim 4, the holes are filled with a mixture of an incompressible material and a bulk material.

Wenn gemäß den Merkmalen des Patentanspruchs 5 die Bohrungen über die gesamte Länge der Rohrwand in ihre Stirnseiten mündend hergestellt werden, erleichtert dies die Herstellung der Bohrungen und damit auch die Fertigung bzw. Rekalibrierung einer Kokille.If according to the features of claim 5, the holes over the entire length of the pipe wall are made opening into their front pages, this facilitates the production of the holes and thus the production or recalibration of a mold.

Die Bohrungen werden nach Patentanspruch 6 bevorzugt mit einem runden Querschnitt hergestellt.The holes are preferably made according to claim 6 with a round cross-section.

Die Erfindung ist nachfolgend anhand eines in den Zeichnungen dargestellten Ausführungsbeispiels näher erläutert. Es zeigen:

Figur 1
in perspektivischer Darstellung den oberen Abschnitt einer Rohrkokille und
Figur 2
die Rohrkokille der Figur 1 in einer geänderten perspektivischen Darstellung, teilweise im Schnitt.
The invention is explained in more detail with reference to an embodiment shown in the drawings. Show it:
FIG. 1
in a perspective view of the upper portion of a tube mold and
FIG. 2
the tube mold of Figure 1 in a modified perspective view, partially in section.

Die in den Figuren 1 und 2 veranschaulichte Rohrkokille 1 weist einen Doppel-Tförmig konfigurierten Querschnitt auf.The tube mold 1 illustrated in FIGS. 1 and 2 has a double-T-shaped configured cross-section.

Sie besitzt eine Rohrwand 2 mit über den Umfang gleichbleibender Dicke D. Folglich ist die durch die Innenwand 3 der Rohrkokille 1 vorgegebene Gießform auch an der Außenfläche 4 verwirklicht.It has a tube wall 2 with uniform thickness over the circumference D. Consequently, the predetermined by the inner wall 3 of the tube mold 1 mold is also realized on the outer surface 4.

In Längsrichtung LR der Rohrkokille 1 verlaufen Bohrungen 5 in der Rohrwand 2. Die Bohrungen 5 erstrecken sich im Abstand parallel zueinander und treten aus den Stirnseiten 6, 7 der Rohrwand 2 aus. Sie besitzen einen kreisrunden Querschnitt.Holes 5 extend in the tube wall 2 in the longitudinal direction LR of the tube mold 1. The holes 5 extend parallel to each other at a distance and exit from the end faces 6, 7 of the tube wall 2. They have a circular cross-section.
