Description

Die Erfindung betrifft ein Setzgestell zur Aufnahme von Brenngut nach dem Oberbegriff des Anspruchs 1.The invention relates to a setting frame for receiving firing material according to the preamble of claim 1.

Ein derartiges Setzgestell ist aus DE 29 39 437 A1 bekannt. Danach ist es vorteilhaft, wenn das Brennhilfsmittel mit vergleichsweise geringen Massen auskommt und trotzdem Gewähr dafür bietet, daß das Brenngut ausreichend abgestützt ist und sowohl von oben als auch von unten mit Wärme beaufschlagt werden kann. Der Ofenaufbau kann dann selbst kürzer gewählt werden, wodurch erheblich an Energie gespart werden kann. Schließlich ergibt sich auch eine höhere Einsatzmöglichkeit des Ofens, da mehr Chargen gefahren werden können. Der Stand der Technik sieht deshalb ein Brennplateau zur Auflagerung des Brenngutes vor, bei dem Stützen aufgestellt sind, die Nuten aufweisen und in den Nuten Querriegel aufnehmen, auf die Überbrückungsleisten aufgesetzt sind. Die Querriegel und die Überbrückungsleisten bestehen aus temperaturwechselbeständigem feuerfestem Material, vorzugsweise rekristallisiertem Siliziumkarbid. Nachteilig ist jedoch die nicht hinreichende Stabilität des Setzgestells.Such a setting frame is made DE 29 39 437 A1 known. Thereafter, it is advantageous if the kiln furniture manages with comparatively low mass and still provides assurance that the kiln sufficient is supported and can be applied both from above and from below with heat. The furnace structure can then be chosen shorter even, which can save a considerable amount of energy. Finally, there is also a higher use of the furnace, as more batches can be driven. The prior art therefore provides a Brennplateau for Auflagerung of the fuel before, are set up in the supports, which have grooves and record in the grooves cross bar, are placed on the bridging strips. The crossbars and the bridging strips are made of heat-resistant refractory material, preferably recrystallized silicon carbide. The disadvantage, however, is not sufficient stability of the setting frame.

US 6 644 966 B1 beschreibt ein Setzgestell mit Stäben, die nach Art eines Rostes über 2 Riegel beabstandet zweinander fixiert sind. Die Riegel weisen Öffnungen auf, in die die Stabenden eingesetzt werden. US Pat. No. 6,644,966 B1 describes a setting frame with rods, which are fixed in two spaced apart in the manner of a grid over two bars. The bars have openings into which the bar ends are inserted.

Aufgabe der Erfindung ist es daher, ein Setzgestell nach dem Oberbegriff des Anspruchs 1 zu schaffen, das mit vergleichsweise geringen Massen an Brennhilfsmitteln auskommt, die Gewähr dafür bieten, daß das Brenngut auf einer stabilen Unterlage ausreichend abgestützt und mit Wärme beaufschlagt werden kann.The object of the invention is therefore to provide a setting frame according to the preamble of claim 1, which manages with comparatively small masses of kiln furniture, provide the guarantee that the kiln can be sufficiently supported on a stable surface and subjected to heat.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.This object is solved by the features of claim 1.

Hierdurch wird ein Setzgestell zur Aufnahme von Brenngut während eines Ofenbrands geschaffen, das die konstruktive Gestaltung einer Steckverbindung als Brennhilfsmittelkonstruktion besitzt. Eine stabile Verbindung der Stäbe und Riegel wird erreicht und ein rostartiges Brennplateau gebildet. Das Setzgestell ist dabei geeignet, mittels Ofenwagen oder direkt als Schlitten durch einen Ofen bewegt zu werden. Das Setzgestell ist also eine transportable, relativ starre Einheit.As a result, a setting frame is provided for receiving fuel during a kiln fire, which has the structural design of a plug connection as Brennhilfsmittelkonstruktion. A stable connection of the bars and bars is achieved and formed a rust-like Brennplateau. The setting frame is suitable to be moved by kiln car or directly as a carriage through a furnace. The setting frame is therefore a transportable, relatively rigid unit.

Vorteilhaft ist ferner, daß das Brenngut von allen Seiten gleichmäßig mit Wärme beaufschlagt werden kann.It is also advantageous that the kiln can be applied uniformly from all sides with heat.

Das Setzgestell erlaubt eine Setzweise, die im Vergleich zur teilweise noch üblichen kompakten Beladung eine signifikante Reduzierung der Brennzyklen und damit verbunden eine Verkürzung der Ofenlänge erlaubt. Neben der Einsparung an Energiekosten erhöht sich dadurch auch die Produktqualität. Die Produktion von beispielsweise Klinkern wird deutlich verbessert.The setting frame allows a setting method that allows a significant reduction of the firing cycles and thus a shortening of the kiln length compared to the still common compact loading. In addition to saving energy costs, this also increases product quality. The production of, for example, clinker is significantly improved.
