Unter Heranziehung der Figuren 1 - 3a wird nun erst einmal das grundsätzlich Neue der Anordnung beschrieben.
Die mit Brenngut beladenen Brennregale 13 werden auf einer dem Ofen 1 vorgelagerten Rampe 16 zu einer Brenncharge zusammengestellt. Das dieser Rampe 16 zugewandte Ofentor 2 des Ofen 1 öffnet hier durch seitliche Verschiebung die Brennkammer la, wobei zuvor der Ofenboden 6 etwas angehoben wurde.
Danach fährt der den Ofenboden 6 tragende Herdwagen 8 unter die Rampe 16, übernimmt hier 16 die Charge von Brennregalen 13 mittels einem auf der Oberseite des Ofenbodens 6 vorgesehenen Distanzgestelles 12, welches 12 mitsamt dem Ofenboden 6 entsprechend angehoben wird, und fährt dann zurück in die Brennkammer la. Das Ofentor 2 wird nun unverzüglich an den Ofen 2 herangeschoben und der Ofenboden 6 mit den darauf befindlichen Brennregalen 13 abgesenkt; anschließend erfolgt der Brennvorgang.
Nach dem Brennvorgang wird der Ofenboden 6 wieder angehoben, das gegenüberliegende Ofentor 3 geöffnet und der Herdwagen 8 fährt nun zur Rampe 19, auf der die Brennregale 13 mit dem gebrannten Brenngut abgestellt werden. Unverzüglich nach dem Abstellen der gebrannten Charge fährt der Herdwagen 8 durch die Brennkammer la hindurch zur Rampe 16, um dort eine neue Brenncharge aufzunehmen und plaziert diese in vorher beschriebener Weise in der Brennkammer. Die Ofentore 2 und 3 werden bei diesem Arbeitsschritt des Be- und Entladens, dem Besatzwechsel, für das Ein- und Ausfahren des Herdwagen 8 entsprechend geöffnet und geschlossen.Using FIGS. 1 - 3a, the fundamentally new aspect of the arrangement will now be described.
The firing racks 13 loaded with firing material are assembled into a firing batch on a ramp 16 upstream of the furnace 1. The furnace gate 2 of the furnace 1 facing this ramp 16 opens the combustion chamber 1 a here by lateral displacement, the furnace base 6 having previously been raised somewhat.
Thereafter, the bogie car 8 carrying the oven floor 6 moves under the ramp 16, here 16 takes over the batch of firing racks 13 by means of a spacer frame 12 provided on the top of the oven floor 6, which 12 is raised accordingly together with the oven floor 6, and then moves back into the Combustion chamber la. The furnace gate 2 is now immediately pushed towards the furnace 2 and the furnace floor 6 with the firing racks 13 located thereon is lowered; then the burning process takes place.
After the firing process, the furnace floor 6 is raised again, the opposite furnace gate 3 is opened and the bogie car 8 now moves to the ramp 19, on which the firing racks 13 with the fired firing material are placed. Immediately after the burned batch has been switched off, the bogie car 8 travels through the combustion chamber la to the ramp 16 in order to take up a new combustion batch there and places it in the combustion chamber in the manner previously described. In this step of loading and unloading, changing the trimmings, the furnace gates 2 and 3 are opened and closed accordingly for the entry and exit of the bogie carriage 8.

Es ist auch im Sinne der Erfindung, die Ofentore 2 und 3 bei herausgefahrenem Herdwagen 8 zwischenzeitlich wieder zu schließen, wobei diese Verfahrensweise unter dem Blickfeld der Dimensionierung des Gesamt-Brennsystems wahlweise angewendet werden kann. Zur Führung des Herdwagens 8 verläuft eine Herdwagenführung 15 von der Rampe 16 unter den Ofen 1 hindurch bis zur Rampe 19.
Zur Höhenverstellung des auf dem Herdwagen 8 angeordneten Ofenbodens 6 ist zwischen dem Unterteil 9 und dem Oberteil 10 des Herdwagens 8 mindestens eine Hubeinheit 11 vorgesehen.
In einer Weiterbildung der Erfindung ist das Oberteil 10 des Herdwagens 8 gleichzeitig als Ofenboden 6 ausgebildet.It is also within the scope of the invention to temporarily close the oven gates 2 and 3 again when the bogie wagon 8 is moved out, this procedure being able to be used selectively in view of the dimensioning of the overall firing system. To guide the bogie carriage 8, a bogie carriage guide 15 runs from the ramp 16 under the furnace 1 to the ramp 19.
To adjust the height of the furnace base 6 arranged on the bogie car 8, at least one lifting unit 11 is provided between the lower part 9 and the upper part 10 of the bogie car 8.
In a development of the invention, the upper part 10 of the hearth trolley 8 is simultaneously designed as a furnace floor 6.

Damit eine zugluftfreie Abdichtung der Brennkammer la gegeben ist, sind die Ofentore 2 und 3, die Ofenseitenwände 17 und 18 und der Ofenboden 6 sowie der später näher beschriebene weitere Ofenboden 22 mit aufeinander abgestimmten profilierten Rändern 2a bzw. 3a, 17a, 18a versehen und die beiden Ofenböden 6 und 22 weisen jeweils einen umlaufenden, nach unten gerichteten Rand 7 auf.
Durch diese neuartige Dichtmethode der Herdwagenöfen entfallen aufwendige Konstruktionen wie Sandrinnen und zwischengelagerte Dichtprofile (-balken); beim Öffnen des Ofenbodens zur Unterstützung der Kühl phase kann durch den auftretenden Luftstrom kein Sand mitgerissen werden und weiterhin ist der Kühlprozeß definierter beeinflußbar. So that a draft-free seal of the combustion chamber la is provided, the furnace doors 2 and 3, the furnace side walls 17 and 18 and the furnace floor 6 and the further furnace floor 22 described later are provided with coordinated profiled edges 2a and 3a, 17a, 18a and the Both furnace floors 6 and 22 each have a peripheral, downward edge 7.
This new sealing method for the bogie hearth furnaces eliminates the need for complex constructions such as sand channels and intermediate sealing profiles (beams); when opening the furnace floor to support the cooling phase, no sand can be entrained by the air flow and the cooling process can also be influenced in a more defined manner.

Zur Entfeinerung von Fertigungstoleranzen ist die Einlage eines vorzugsweise am Ofenboden 6 bzw. 22 befestigten, unprofilierten Dichtmaterials zwischen den Rändern 2a, 3a, 17a, 18a und 7 möglich. Das Gewicht des Ofenbodens 6 bewirkt ein luftdichtes Schließen.For the refinement of manufacturing tolerances Insert one preferably on the furnace floor 6 or 22 attached, unprofiled sealing material between the edges 2a, 3a, 17a, 18a and 7 possible. The Weight of the oven base 6 causes an airtight Conclude.

Die Fig. 4 - 4b zeigen in geschnittenen Ansichten die Ausstattung eines Ofen 1 mit bodenseitigen Abgasabzügen 21, die gleichzeitig mit dem Absenken des die Brennkammer la schließenden Ofenbodens 6 formschlüssig an die Abgasfüchse 23 anschließen.4 - 4b show in sectional views the equipment of a furnace 1 with exhaust fumes on the bottom 21, which coincides with the lowering of the the combustion chamber la closing furnace bottom 6 positively connect to the exhaust foxes 23.

Die in den Fig. 1 - 3a dargestellte Ausführungsvariante des Ofen 1 ist dagegen mit in der Ofendecke 4 vorgesehenen Abgasabzügen 5 versehen.The embodiment shown in FIGS. 1-3a the furnace 1, however, is provided in the furnace ceiling 4 Exhaust fume cupboards 5 provided.

In einer nicht dargestellten Weiterbildung der Erfindung wird die die gebrannte Charge zwischenzeitlich lagernde Rampe 19 neben der bereitstellenden Rampe 16 angeordnet und die Rampe 16 bzw. 19 jeweils wechselnd über der Herdwagenführung 15 positioniert. Die Anwendung dieser Ausgestaltungsvariante ist von der kundenbezogenen, gesamten baulichen Anlagenkonzeption abhängig. In a further development of the invention, not shown is the burned batch in the meantime stocking ramp 19 next to the providing ramp 16 arranged and the ramp 16 and 19 respectively alternately positioned above the bogie carriage guide 15. The application of this design variant is from the customer-related, overall structural system design dependent.

Eine weitere Ausgestaltung des erfinderischen Grundgedankens besteht darin, in Abhängigkeit von Größe und Form des Brenngutes die Brennregale mit höhenverstellbaren Regalböden auszustatten und unter Beachtung des Gesamtgewichtes der Brenncharge mehrere Hubeinheiten am Herdwagen 8 vorzusehen und im Bedarfsfall zusätzlich den Ofenboden 6 bzw. 22 in mehrere Segmente zu unterteilen.Another embodiment of the inventive concept consists of depending on size and shape of the firing goods the firing racks with height adjustable Equip shelves and keep in mind of the total weight of the firing batch several lifting units to be provided on the bogie wagon 8 and if necessary in addition the furnace floor 6 or 22 in several segments to divide.

Darüber hinaus ist durch das beschriebene neuartige Brennverfahren und der zugeordneten Anordnung mit den besagten Weiterbildungen die beste Voraussetzung gegeben, einen derartig gestalteten Fertigungsabschnitt - Brennen - teil- oder vollautomatisiert aufzubauen und zudem einen solchen Brenn-Fertigungsabschnitt in eine zumindest teilweise automatisierte Fertigungsstraße für Keramikteile o. dgl. Produkte zu integrieren.In addition, is described by the novel Burning process and the associated arrangement with the best prerequisites for the training courses in question given a manufacturing section designed in this way - Burning - to be set up partly or fully automatically and also such a firing manufacturing section in an at least partially automated production line for ceramic parts or similar products to be integrated.

Ein positiver Effekt anderer Art besteht nun noch darin, den ohnehin vorgesehenen Arbeitstakt - Heben des Ofenbodens 6 bzw. 22 - in den zum Brennvorgang gehörigen Arbeitstakt - Abkühlen - einzubinden oder auch darin, die Brennregale 13 innerhalb der gesamten Fertigungsstraße einzusetzen, wodurch das Umlagern des Brenngutes vor und nach dem Brennen entfällt. A different kind of positive effect still exists in the already planned work cycle - lifting of the furnace bottom 6 or 22 - in the for the burning process proper work cycle - cooling - to integrate or also in that the burning shelves 13 within the entire Use production line, which makes the relocation of the firing material before and after firing is omitted.
