Brenngestellaufbau Burning rack structure
Die Erfindung betrifft einen Brenngestellaufbau aus SiC-Säulen und Tragelemente zur Aufnahme von abnehmbaren Setzrahmen bzw. Setzgestell geeignet ist. Hochtemperaturbehandlungen zum Sintern, Tempern, Wärmebehandeln von Bauteilen, folgend Brennen genannt, fordert für schnelle Brennzyklen in sogenannten Schnellbrandöfen hochtemperaturbeständige und formstabile Aufbausysteme, in denen das Brenngut durch die Hochtemperaturanlage in möglichst kurzer Zeit transportiert wird. Die dazu erforderlichen Materialien für den Aufbau dieser Gestelle müssen daher auch eine sehr hohe Temperaturwechselbeständigkeit undThe invention relates to a combustion frame structure made of SiC columns and supporting elements for receiving removable frame or frame is suitable. High-temperature treatments for sintering, tempering, heat-treating components, hereinafter called firing, require high-temperature-resistant and dimensionally stable construction systems for fast firing cycles in so-called rapid firing ovens, in which the fired material is transported through the high-temperature system in the shortest possible time. The materials required for the construction of these frames must therefore also have a very high resistance to temperature changes and

Typische Brenntemperaturen liegen hier zwischen 900 - 1400 °C, im Bereich der Oxidkeramiken werden auch Temperaturen bis 1800 °C gefordert. Die Ofenatmosphären müssen dem Brenngut entsprechend angepaßt werden, d.h. oxidierende Atmosphären für z.B. Geschirr- und Baukeramiken, sauerstoffreie Atmosphä- ren für z.B. zum Sintern oder Wärmebehandeln von metallischen Brenngütern.Have rigidity so that relatively light firing frame constructions with a low weight can transport the highest possible firing load through the furnace. Typical firing temperatures are between 900 - 1400 ° C, in the area of oxide ceramics temperatures up to 1800 ° C are also required. The furnace atmospheres must be adapted accordingly to the firing material, i.e. oxidizing atmospheres for e.g. Tableware and building ceramics, oxygen-free atmospheres for e.g. for sintering or heat treating metallic firing materials.

Brenngut erlaubt. Entscheidend für eine erfolgreiche Brenngestellkonstruktion sind dabei die Übergangselemente, an denen die einzelnen Bauteile des Brenngestells miteinander verbunden werden. Hier werden ne- ben den thermozyklischen Beanspruchungen die Kraftübertragungen realisiert, darüber hinaus müssen an diesen Stellen die dilatometrischen Veränderungen der Bauteile während der Brennzyklen aufgefangen und ausgeglichen werden. Ein gelungenes Beispiel für eine derartige Brenngestellkonstruktion wird in DE 196 53 483 AI als Hängevorrichtung für den Einsatz zum Brennen von keramischen Bauteilen oder in DE 34 34 181 C2 als Hohlstütze mit Querdurchbrüchen demonstriert. Hier werden gezielt sämtliche Punktbelastungen, die zu lokalen Spannungsüberhöhungen und somit Bruch im sprödbruchempfindlichen Brenngestellbauteil führen könnten, vermieden.Firing material allowed. The transition elements, on which the individual components of the firing frame are connected, are decisive for a successful firing frame construction. Here, in addition to the thermocyclic loads, the power transmissions are realized. In addition, the dilatometric changes in the components during the firing cycles must be absorbed and compensated for at these points. A successful example of such a firing frame construction is demonstrated in DE 196 53 483 AI as a hanging device for use in firing ceramic components or in DE 34 34 181 C2 as a hollow support with transverse openings. Here, all point loads that could lead to local stress increases and thus breakage in the brittle fracture-sensitive firing frame component are specifically avoided.
Ziel der Erfindung ist es, eine Brenngestellkonstruk- tion zu erhalten, die eine komplette vollautomatisierte Entnahme der sogenannten Setzrahmen bzw. Tragrahmen mitsamt Brenngut zum Be- und Entladen zwischen den Brennzyklen ermöglicht. Derartige flexible Brenngestellaufbauten können den Arbeitsablauf in sämtlichen vollautomatisierten Materialflüssen in deren Brennprozeßtechnik maßgeblich rationeller und flexibler gestalten lassen, da die kompletten Tragrahmen in Puffern zwischengelagert werden können und bei entsprechendem Fertigungsbedarf aktiviert, d.h. in die Brenngestellsäulen eingesetzt werden. In der hier dargestellten Erfindung wird einerseits eine hochstabile Aufnahmevorrichtung zwischen Brenn- gestellsäule und Tragelementen wie z.B. Querbalken, Traversen etc. realisiert. Zusätzlich ist es gelun- gen, die dilatometrischen Längenänderungen der Brenngestellbauteile durch entsprechende Rollbewegungen auszugleichen.The aim of the invention is to obtain a firing frame construction which enables a completely fully automated removal of the so-called setting frame or supporting frame together with the firing material for loading and unloading between the firing cycles. Such flexible firing frame assemblies can make the workflow in all fully automated material flows in their firing process technology significantly more efficient and flexible, since the complete support frames can be stored temporarily in buffers and activated if there is a corresponding need for production, ie are used in the firing frame columns. In the invention shown here, on the one hand, a highly stable holding device between the combustion frame column and supporting elements, such as, for example, crossbeams, traverses, etc., is realized. In addition, the dilatometric changes in length of the internal frame components have been compensated for by appropriate rolling movements.
Die Erfindung gewährleistet weiter einen Ausgleich der Verdrillbewegungen und/oder Dilatationen durch Rollbewegungen der tragenden Bauteilen, indem die Quer- und Längselemente oder besser Tragelemente über sogenannte Nasenprofile mit Aussparungen und/oder Positionierstegen ineinander positioniert werden, und die Rollbewegung zwischen den Tragelementen (Quer- und Längstraversen) derart realisiert wird, daß zwischen den Tragelementen ein Rundstab eingelegt wird. Dieser wird auf dem unteren Tragelement in einer entsprechenden Ausformung eingelegt und positioniert und kann sich innerhalb dieser Ausformung rollend bewegen.The invention further ensures a compensation of the twisting movements and / or dilatations by rolling movements of the load-bearing components, in that the transverse and longitudinal elements or better supporting elements are positioned one inside the other via so-called nose profiles with recesses and / or positioning bars, and the rolling movement between the supporting elements (transverse and Longitudinal beams) is realized in such a way that a round rod is inserted between the supporting elements. This is inserted and positioned on the lower support element in a corresponding shape and can move in a rolling manner within this shape.

Tragelemente über sogenannte Nasenprofile mit Aussparungen und/oder Positionierstegen ineinander positioniert werden, und die Rollbewegung zwischen den Tragelementen (Quer- und Längstraversen) derart realisiert wird, indem die unten liegende Traverse als Rolle ausgebildet wird und die obenliegende Traverse sich auf dieser Rolle innerhalb der Positionierungen bewegen kann. Diese Rollen können dann z.B. in einer entsprechenden Auf- nahmevorrichtung gelagert sein und sich in dieser in- nerhalb entsprechend der übertragenden Rollbewegungen bewegen.Cross and longitudinal elements or supporting elements are positioned in one another via so-called nose profiles with recesses and / or positioning webs, and the rolling movement between the supporting elements (transverse and longitudinal cross members) is realized in such a way that the traverse located below is designed as a roller and the upper traverse itself can move on this role within the positioning. These rollers can then be stored in a corresponding receiving device, for example, and can be located in this move in accordance with the transferring rolling movements.
Die Auflagerkonstruktion zur Aufnahme der Tragelemen- te (Traversen etc.), wird dahingehend realisiert, daß durch die Tragsäule über Bohrungen Auflagerelemente gesteckt werden, welche anschließend stoffschlüssig miteinander verbunden werden. Die stoffschlüssige Verbindung kann durch verschiedene Fügetechniken er- reicht werden:The support structure for receiving the support elements (cross members, etc.) is implemented in such a way that support elements are inserted through the support column through bores, which are then connected to one another in a cohesive manner. The integral connection can be achieved using various joining techniques:

Die stoffschlüssige Verbindung wird also in einem anschließenden gemeinsamen Brand realisiert, bei dem der Verbund zu den Bauteilen arteigen ist.(a) Joining the components in the unfired, so-called green state (garnish) and then sintering, reaction bonding, siliconization, recrystallization. The integral connection is thus realized in a subsequent joint fire, in which the bond to the components is unique.
