Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren und eine Vorrichtung zur festen Verbindung von keramischen Formteilen mit Metallen, insbesondere mit einem aus Stahlguß bestehenden metallischen Träger, wobei das keramische Formteil mit einem Werkstoff umgeben und mit dem Metall thermisch verbunden wird.The invention relates to a method and a device for the firm connection of shaped ceramic parts with metals, in particular with a metallic support made of cast steel, the shaped ceramic part being surrounded by a material and being thermally bonded to the metal.
Aus der EP-OS 01 64 537 ist ein Verfahren zur Herstellung einer festen Verbindung von hochverschleißfesten Platten, insbesondere Keramikplatten,mit einem vor Verschleiß zu schützendem Träger bekannt, wobei Preßmetall zwischen zwei Lötfolien eingebettet und durch Erhitzen ein Mehrkomponentenwerkstoff zwischen den verschleißfesten Platten und dem Träger gebildet wird. Auf diese Weise wird einerseits eine feste Verbindung der hochverschleißfesten Platte, insbesondere Keramikplatte, mit dem Träger erreicht, und andererseits werden hierdurch die Wärmedehnungsunterschiede zwischen der hochverschleißfesten Platte und dem Träger kompensiert. Dieses bekannte Verfahren eignet sich daher besonders für eine feste und sichere Verbindung von Keramikplatten mit der Wendel der Förderschnecke einer Schneckenzentrifuge.From EP-OS 01 64 537 a method for producing a firm connection of highly wear-resistant plates, in particular ceramic plates, with a carrier to be protected against wear is known, wherein pressed metal is embedded between two solder foils and a multi-component material between the wear-resistant plates and the carrier by heating is formed. In this way, on the one hand, a firm connection of the highly wear-resistant plate, in particular ceramic plate, to the carrier is achieved, and on the other hand, this compensates for the thermal expansion differences between the highly wear-resistant plate and the carrier. This known method is therefore particularly suitable for a firm and secure connection of ceramic plates to the screw of the screw conveyor of a screw centrifuge.
Ausgehend von diesem bekannten Verfahren besteht die Aufgabe der Erfindung darin, eine feste Verbindung von keramischen Formteilen mit Metallen zu schaffen, die ohne Beeinträchtigung von Material und Festigkeit auch verhältnismäßig hohe Temperaturwechselbeanspruchungen aufnehmen kann.Based on this known method, the object of the invention is to provide a firm connection of shaped ceramic parts with metals, which can also absorb relatively high thermal shock loads without impairing the material and strength.
Diese Aufgabe wird dadurch gelöst, daß als Werkstoff ein Wärmedehnung aufnehmendes, elastisches, feuerfestes Material verwendet wird, und daß die thermische Verbindung des keramischen Formteils mit dem Metall und/oder metallischem Träger durch Umgießen von flüssigem Metall erfolgt. Auf diese Weise gelingt es, wie die Praxis gezeigt hat, durch geeignete Wahl des Werkstoffes eine feste und sichere Verbindung von Keramikplatten mit Metallen zu erreichen und aufrechtzuerhalten, wenn die keramischen Formteile mit den Metallen, insbesondere mit dem aus Stahlguß bestehenden metallischen Trägern, sehr hohen Temperaturwechselbelastungen ausgesetzt werden.This object is achieved in that an elastic, fire-resistant material absorbing thermal expansion is used as the material, and in that the thermal connection of the ceramic molded part to the metal and / or metallic carrier is carried out by encapsulating liquid metal. In this way, as practice has shown, it is possible to achieve and maintain a firm and secure connection of ceramic plates with metals by suitable choice of the material, if the ceramic molded parts with the metals, in particular with the metallic supports made of cast steel, are very high Exposed to changes in temperature.
In vorteilhafter Weiterbildung der Erfindung wird das keramische Formteil im gesamten Verbindungsbereich vom Werkstoff umgeben und durch Eingießen von flüssigem Metall mit diesem oder mit dem metallischen Träger verbunden. Hierdurch wird ein allseitiger Ausgleich der Temperaturwechselbelastungen zwischen dem keramischen Formteil und dem metallischen Träger gewährleistet.In an advantageous development of the invention, the ceramic molded part is surrounded by the material in the entire connection area and connected to it or to the metallic carrier by pouring liquid metal. This ensures an all-round compensation of the thermal shock loads between the ceramic molded part and the metallic carrier.
Gegebenenfalls kann jedoch auch eine ausreichend feste Verbindung von keramischen Formteilen mit Metallen erreicht werden, wenn nur der Außenrand des keramischen Formteils mit dem Werkstoff umgeben und mit der Metallschmelze umgossen wird. Als Werkstoffe können hierbei sehr vorteilhaft keramische Fasern oder auch Fasern von Boriden, Karbiden oder Aluminiumoxid in Form von Vliesen, Filzen oder geflochtenen Bändern verwendet werden. Auch Werkstoffe aus Metall und oxidkeramischen Fasern sind besonders gut geeignet, um die stark unterschiedlichen Wärmedehnungen zwischen dem keramischen Formteil und dem Metall oder metallischen Träger aufzunehmen und zu kompensieren.If necessary, however, a sufficiently firm connection of shaped ceramic parts with metals can be achieved if only the outer edge of the shaped ceramic part is surrounded by the material and cast with the molten metal. Ceramic materials or fibers of borides, carbides or aluminum oxide in the form of nonwovens, felts or braided tapes can be used very advantageously as materials. Materials made of metal and oxide-ceramic fibers are also particularly well suited to absorbing and compensating for the greatly different thermal expansions between the ceramic molded part and the metal or metallic carrier.
Weitere Einzelheiten, Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Erläuterung von in den Zeichnungsfiguren schematisch dargestellten Vorrichtungen.Further details, features and advantages of the invention result from the following explanation of devices schematically represented in the drawing figures.

- 1 shows a metal-ceramic connection according to the invention in cross section,

Wie Fig. 1 zeigt, besteht die Metall-Keramik-Verbindung gemäß der Erfindung aus einem im Querschnitt konisch ausgebildeten keramischen Formteil (10) und einem metallischen Träger (11), die miteinander über einen, den Außenrand des keramischen Formteils (10) umgebenden Werkstoff (12), der aus einem Wärmedehnung aufnehmenden, elastischen, feuerfesten Material besteht, form- und kraftschlüssig verbunden sind. Die Herstellung dieser Metall-Keramik-Verbindung erfolgt, wie Fig. 2 zeigt, derart, daß das keramische Formteil (10) außen mit dem Werkstoff (12) umspannt von oben mittig in eine Gießform eingelegt und anschließend mit flüssigem Metall (11) umgossen wird. Das abgekühlte und erstarrte Metall (11) bildet hierbei gleichzeitig den Träger des keramischen Formteils (10). Beim Abkühlen der Metallschmelze (11) in der Gußform (13) erfolgt eine Schrumpfung durch die auch der zwischen der Metallschmelze (11) und dem keramischen Formteil (10) befindliche Werkstoff (12) mehr oder weniger stark zusammengepreßt wird. Auf diese Weise wird sehr vorteilhaft neben einer formschlüssigen Metall-Keramik-Verbindung auch eine kraftschlüssige Verbindung durch Schrumpfsitz des im metallischen Träger (11) befindlichen keramischen Formteils (10) bewirkt. Durch die im Querschnitt konische Ausbildung des keramischen Formteils (10) können auch bei unsymmetrischen thermischen Belastungen während des Schrumpfvorganges ungleichmäßige Erstarrungsdrücke gedämpft und ausgeglichen werden. Ein weiterer Vorteil dieser konischen Ausbildung des keramischen Formteils (10) besteht darin, daß sich das keramische Formteil (10) auch bei hohen thermischen und mechanischen Belastungen nie lösen und aus dem metallischen Träger (11) herausfallen kann. Sobald die Metallschmelze (11) in der Gußform (13) erstarrt und abgekühlt ist, wird diese Metall-Keramik-Verbindung gemäß der Erfindung aus der Gußform (13) nach oben herausgenommen und kann als solche, mit der oben freiliegenden Keramikfläche gemäß Fig. 1 bei Maschinen und Anlagen an besonders korrosions- und abrasionsgefährdeten Stellen mit Vorteil eingesetzt werden. Gegebenenfalls kann es auch zweckmäßig sein, wie in den Fig. 1 und 2 gestrichelt angedeutet ist, das keramische Formteil (10) im gesamten Verbindungsbereich, d. h. auch zwischen der unteren Seite (14) und dem Träger (11) einen Werkstoff (15) anzuordnen. Dies insbesondere dann, wenn diese erfindungsgemäß ausgebildete Metall-Keramik-Verbindung einer besonders hohen Temperaturwechselbelastung ausgesetzt wird. Als Werkstoffe kommen hierbei vor allem keramische Fasern oder Fasern von Boriden, Karbiden oder Aluminiumoxiden in Betracht, die sehr hohe und stark schwankende, unterschiedliche Wärmedehnungen zwischen dem keramischen Formteil (10) und dem Metallträger (11) aufnehmen können, und zwar ohne Beeinträchtigung der festen Verbindung und der zu verbindenden Materialien. Auch die Dicke des Werkstoffes (12) kann in Abhängigkeit der unterschiedlichen Wärmeausdehnungskoeffizienten zwischen dem metallischen Träger (11) und dem keramischen Formteil (10) jeweils so dimensioniert und abgestimmt werden, daß auch bei extremen thermischen und mechanischen Belastungen eine feste Verbindung des keramischen Formteils (10) mit dem metallischen Träger (11) gewährleistet ist. Zum Ein- oder Umgießen der keramischen Formkörper (10) können Hartmetalle oder auch Weichmetalle, insbesondere Aluminiumlegierungen mit hohen Wärmeausdehnungskoeffizienten herangezogen werden. Wesentlich hierbei ist jedoch die Wahl des jeweiligen Werkstoffes hinsichtlich der Zusammensetzung und der Anordnung zwischen dem keramischen Formteil (10) und dem metallischen Träger (11).As shown in FIG. 1, the metal-ceramic connection according to the invention consists of a ceramic molded part (10) with a conical cross section and a metallic support (11), which are connected to one another via a material surrounding the outer edge of the ceramic molded part (10) (12), which consists of a thermal expansion absorbing, elastic, refractory material, are positively and non-positively connected. This metal-ceramic connection is produced, as shown in FIG. 2, in such a way that the ceramic molded part (10) is externally spanned with the material (12), placed in the center of a mold from above and then cast with liquid metal (11) . The cooled and solidified metal (11) also forms the carrier of the ceramic molded part (10). When the metal melt (11) cools down in the casting mold (13), the material (12) located between the metal melt (11) and the ceramic molded part (10) also shrinks more or less is strongly pressed together. In this way, in addition to a form-fitting metal-ceramic connection, a non-positive connection is also very advantageously brought about by the shrink fit of the ceramic molded part (10) located in the metallic carrier (11). The conical design of the ceramic molded part (10) enables uneven solidification pressures to be dampened and compensated for even with asymmetrical thermal loads during the shrinking process. Another advantage of this conical design of the ceramic molded part (10) is that the ceramic molded part (10) can never come loose even at high thermal and mechanical loads and can fall out of the metallic carrier (11). As soon as the molten metal (11) in the casting mold (13) has solidified and cooled, this metal-ceramic connection according to the invention is removed from the casting mold (13) upwards and, as such, can be used with the exposed ceramic surface according to FIG. 1 can be used to advantage in machines and systems in places particularly prone to corrosion and abrasion. If necessary, it can also be expedient, as indicated by the broken lines in FIGS. 1 and 2, to arrange the ceramic molded part (10) in the entire connection area, ie also between the lower side (14) and the carrier (11), a material (15) . This is particularly the case when this metal-ceramic connection designed according to the invention is exposed to a particularly high temperature change load. The materials used here are in particular ceramic fibers or fibers of borides, carbides or aluminum oxides, which can absorb very high and strongly fluctuating, different thermal expansions between the ceramic molded part (10) and the metal carrier (11), without impairing the solid Connection and the materials to be connected. The thickness of the material (12) can also vary depending on the Thermal expansion coefficients between the metallic carrier (11) and the ceramic molded part (10) are each dimensioned and coordinated such that a firm connection of the ceramic molded part (10) with the metallic carrier (11) is ensured even under extreme thermal and mechanical loads. Hard metals or soft metals, in particular aluminum alloys with high coefficients of thermal expansion, can be used to cast or cast the ceramic shaped bodies (10). What is important here, however, is the choice of the respective material with regard to the composition and the arrangement between the ceramic molded part (10) and the metallic carrier (11).
Schließlich kann, wie Fig. 3 zeigt, auch sehr vorteilhaft ein im Querschnitt konisch ausgebildetes keramisches Formteil (16) in eine entsprechende Ausnehmung (17) eines metallischen Trägers (18) aus Stahlguß eingebettet werden. Zum Zwecke einer festen Verbindung des keramischen Formteils (16) mit dem Träger (18) ist zwischen dem Außenrand (19) des keramischen Formteils (16) und dem metallischen Träger (18) ein Spalt (20) für die Aufnahme des Werkstoffes (21) und der Metallschmelze (22) vorgesehen. Die Verbindung des keramischen Formteils (16) mit dem Träger (18) erfolgt hierbei durch Eingießen von flüssigem Metall in den zwischem dem Werkstoff (21) und dem Träger (18) befindlichen Spalt. Diese in Fig. 3 dargestellte Metall-Keramik-Verbindung gemäß der Erfindung eignet sich besonders als Verschleißschutz bei Schubrostkühlern, insbesondere im Kühlgutaufnahmebereich, wo die Rostkühlerplatten einer besonders hohen Abrasions- und Tempeaturwechselbelastung ausgesetzt sind.Finally, as shown in FIG. 3, a ceramic molded part (16) with a conical cross-section can also be very advantageously embedded in a corresponding recess (17) of a metallic support (18) made of cast steel. For the purpose of a firm connection of the ceramic molded part (16) to the carrier (18) there is a gap (20) for receiving the material (21) between the outer edge (19) of the ceramic molded part (16) and the metallic carrier (18). and the molten metal (22) is provided. The ceramic molded part (16) is connected to the carrier (18) by pouring liquid metal into the gap between the material (21) and the carrier (18). This metal-ceramic connection shown in FIG. 3 according to the invention is particularly suitable as wear protection for thrust grate coolers, in particular in the cooling goods receiving area, where the grate cooler plates are exposed to a particularly high abrasion and temperature change load.
Der Gegenstand der Erfindung ist nicht auf die in den Zeichnungsfiguren dargestellten Ausführungsbeispiele beschränkt. So können die keramischen Formteile beispielsweise auch mit gerade verlaufenden Rändern und auch sonst beliebig ausgebildet sein. Dasselbe gilt auch für die metallischen Träger der keramischen Formteile.The object of the invention is not to the embodiments shown in the drawing figures limited. For example, the ceramic molded parts can also be designed with straight edges and in any other way. The same also applies to the metallic supports of the ceramic molded parts.
