Description

Die Erfindung betrifft eine Halterung für einen keramischen Wagenaufbau zum Halten von zu brennenden Rohlingen aus keramischem Material, insbesondere zu brennenden Dachziegelrohlingen, nach dem Oberbegriff des Anspruchs 1.The invention relates to a holder for a ceramic car body for holding blanks made of ceramic material to be burned, especially for burning roof tile blanks, according to the preamble of Claim 1.

Dachziegelrohlinge werden nach dem Trocknen zum Brennen mittels keramischen Wagenaufbauten auf Ofenwagen positioniert und treten dann eine längere Ofenreise an. Für die keramischen Wagenaufbauten, auch als Brennhilfsmittel bezeichnet, ist es bekannt, grobkeramisches Material, etwa Cordierit, zu verwenden, das die Dachziegelrohlinge horizontal nebeneinander oder mit Abstand übereinander angeordnet aufnimmt. Hierbei dienen als Halterungen für die Rohlinge sogenannte H-Kassetten, die in Seitenansicht im wesentlichen H-förmig sind, wobei der Mittelsteg an die jeweilige Form des Rohlings zur entsprechenden Abstützung hiervon angepaßt ist. Diese H-Kassetten sind mit den davon aufgenommenen Rohlingen horizontal übereinander stapelbar. Abgesehen davon, daß diese H-Kassetten trotz ihrer Wabenstruktur aus Stabilitätsgründen eine erhebliche Masse bilden, die zusätzlich zu den Dachziegelrohlingen zu erhitzen ist, sind je nach Rohlingsform andere H-Kassetten zu verwenden. Roof tiles are used for burning after drying ceramic car bodies positioned on kiln cars and then enter one longer oven journey. For ceramic car bodies, also as Called kiln furniture, it is known to have rough ceramic material, for example Cordierite, to use that the roof tile blanks horizontally next to each other or takes up one above the other. Here serve as Brackets for the blanks so-called H-cassettes, the side view in are substantially H-shaped, with the central web to the respective shape of the Blank for appropriate support is adapted from this. These H-cassettes can be stacked horizontally on top of each other with the blanks they contain. Apart from the fact that these H-cassettes despite their honeycomb structure Stability reasons form a significant mass, in addition to the Depending on the shape of the blank, other H-cassettes are to be heated to use.

Aufgabe der Erfindung ist es, eine Halterung für einen keramischen Wagenaufbau nach dem Oberbegriff des Anspruchs 1 zu schaffen, deren Masse im Vergleich zur aufgenommenen, zu brennenden Masse erheblich reduziert ist und die an die Form von zu brennenden Rohlingen in einfacher Weise anpaßbar ist.The object of the invention is to provide a holder for a ceramic To create car body according to the preamble of claim 1, its mass compared to the absorbed mass to be burned is considerably reduced and adaptable to the shape of blanks to be burned in a simple manner is.

Diese Aufgabe wird entsprechend dem kennzeichnenden Teil des Anspruchs 1 gelöst.This task is performed according to the characteristic part of the Claim 1 solved.

Derartige Halterungen sind nicht nur von einfacher Konstruktion, sondern ermöglichen auch eine wesentliche Massenreduzierung aufgrund der Hohlprofil-Gitterstruktur und der hohen Festigkeit des verwendeten Werkstoffs, so daß das Verhältnis von zu erwärmender zu zu brennender Masse erheblich günstiger wird. Dies wird insbesondere begünstigt durch den Einsatz von keramischen Leichtprofilen, d.h. Profilen geringer Wandstärke und damit geringer Masse. Obwohl die Halterungen auch zur übereinander gestapelten Anordnung von zu brennenden Rohlingen verwendet werden können, ermöglichen sie auch eine Verwendung in Schrägstellung, mit der eine erhöhte Setzdichte erreichbaar ist. Die Halterungen eignen sich vorzugsweise für im wesentlichen plattenförmige keramische Rohlinge, insbesondere Dachziegelrohlinge. Alle Teile des keramischen Wagenaufbaus bestehen zweckmäßigerweise aus siliciuminfiltriertem, reaktions-gebundenem Siliciumkarbid, siliciumnitridgebundenem Siliciumkarbid oder rekristallisiertem Siliciumkarbid. Ein derartiger keramischer Wagenaufbau eignet sich außerdem für den Schnellbrandeinsatz. Durch entsprechendes Einsetzen von Auflagestücken läßt sich die Halterung für unterschiedliche Rohlingsformen verwenden, ohne daß deren Masse wesentlich vergrößert werden müßte.Such brackets are not only of simple construction, but also enable a substantial reduction in mass due to the hollow profile lattice structure and the high strength of the material used, so that Ratio of mass to be heated to burning is considerably cheaper. This is particularly favored by the use of ceramic Light profiles, i.e. Profiles of low wall thickness and thus low mass. Although the brackets can also be stacked on top of each other burning blanks can also be used Use in an inclined position, with which an increased setting density can be achieved. The brackets are preferably suitable for essentially plate-shaped ceramic blanks, in particular roof tile blanks. All parts of the Ceramic car bodies expediently consist of silicon-infiltrated, reaction-bonded silicon carbide, silicon nitride bonded silicon carbide or recrystallized silicon carbide. A Such ceramic car body is also suitable for Rapid fire deployment. By appropriate insertion of supports use the holder for different blank shapes without whose mass would have to be increased significantly.
