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 explosive calibration of 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 chilled block molds, in which in the tube walls Cooling channels introduced parallel to the longitudinal axis are provided, which with a Coolant can be applied.

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 in the Mold walls have vertical and / or horizontal channels into which Temperature measuring elements can be used.

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 replace it after one out of service for a certain period of time and recalibrate it. To this For this purpose, each mold is first chrome-plated and then ground out. Subsequently a calibration mandrel is inserted into the mold The outer dimensions correspond to the inner dimensions of a new mold. To When the calibration mandrel is inserted, the end faces of the mold become tight with plates locked.

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.Then the outer surface of the mold is covered with a suitable explosive and this in an explosion-filled container filled with a liquid medium brought. Due to the explosion energy released on the one hand and the back pressure of the liquid medium, on the other hand, becomes the inner wall of the mold pressed against the calibration mandrel. In this way, the mold receives the the exact inner contour required for their use in the casting operation.

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 process, however, it is due to the wear of the mold during casting and by grinding out after chrome removal, not to avoid material is removed and therefore the wall thickness of the mold during a repair reduced and consequently the external 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.Around the holes in the mold, be they as cooling channels or as receptacles intended for temperature measuring elements, not inadmissible during explosive calibration deform, filler pieces, preferably made of stainless steel, are introduced that are precisely adapted to the holes. Both the manufacture these filler pieces as well as their assembly in the holes and their disassembly associated with a comparatively high expenditure of time and production.

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.Starting from the prior art, the invention is based on the object Process for explosive calibration of molds, in particular in the form of tube or Block molds, to create the easier to control and with a lower Effort is connected.

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

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. A Measure is the reinforcement of the end areas of the mold before Blasting calibration. This is done in particular by a build-up welding, so that the wall thickness losses are compensated for by casting. To the Bores in the mold wall during explosive calibration are not inadmissible to deform, they are now calibrated with a flowable before explosive calibration Material filled in and sealed at the ends. By using a flowable material can also on a comparatively simple basis different cross sections of the holes are taken into account. targeted Filler pieces placed on the cross sections of the holes are no longer required. The costly and time-consuming effort required for this is eliminated perfect.

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 they are in the case of a mold around a tubular or block mold made of copper or Copper alloy.

Die Bohrungen können nach Patentanspruch 2 mit einem inkompressiblen Material, wie z.B. Wasser, ausgefüllt werden.The holes can be made according to claim 2 with an incompressible material, such as. 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 bores according to claim 3 with be filled in a bulk material. Here is the compressibility of the bulk material in connection with its pore volume. The higher the compression of the Bulk material and the finer the grain size, the lower the pore volume of the Bulk goods 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. Another embodiment of the method according to the invention consists in that according to claim 4, the holes with a mixture of 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 on the the entire length of the tube wall is made into the ends of its ends, this facilitates the production of the bores and thus also the production or Recalibration of a mold.

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

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

Die in den Figuren 1 und 2 veranschaulichte Rohrkokille 1 weist einen Doppel-Tförmig konfigurierten Querschnitt auf.The tubular mold 1 illustrated in FIGS. 1 and 2 has a double T-shape 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 a constant thickness D over the circumference is the casting mold predetermined by the inner wall 3 of the tubular mold 1 also on the External surface 4 realized.
