Description

Verfahren zur Herstellung von Backofen-Herdplatten u. dgl. Backofensteinen Als all-einein bekannt und in aller Welt verbreitet gelten für das Verfahren zur Herstellun g von Backofen-Herdplatten u. dgl. Backofensteinen die so-enannten Radeburger Backofenplatten aus Radeburg in Sachsen.Process for the production of oven hotplates and similar oven stones The so-called Radeburg oven plates from Radeburg in Saxony apply to the process for the production of oven hob plates and similar oven stones.

Ihre Herstellung beruht auf einem seltenen Vorkommen eines stark zersetzten Porphyrs.Their production is based on a rare occurrence of a heavily decomposed one Porphyry.

Das genannte Mineral ist so weit verwittert und kaolinisiert, daß es als Ganzes sowohl die Bindemittel als auch 'Magerungsmittel für die Herstellung der Backofenplatten enthält.The mineral mentioned is so weathered and kaolinized that it as a whole both the binders and 'lean agents for manufacture the oven plate contains.

Diesem Vorteil steht entgegen, daß die Verwitterung in dem Vorkommen nicht gleichmäßig auftritt, sondern viele Stufen aufweist, die eine sorgfältige Gewinnun-, Sortierung und Verrnischun- erforderlich I ZD machen oder sonnt zu vielen Fabrikationsfehlern führt. Gegenstand der vorliegenden Erfindung ist ein Verfahren, an Stelle des stark verwitterten Produkts Granulite von Porphyr, Granit oder Syenit zu verwenden, die im wesentlichen als Magerungsmittel dienen, denen erfindungsgemäß bestimmte feuerfeste Tone als Bindemittel systematisch zugesetzt werden.This advantage is opposed to the fact that the weathering in the deposit does not occur uniformly, but has many stages, which a careful Profit-, sorting and blending- required I ZD or suntan too many Manufacturing defects leads. The present invention relates to a method instead of the heavily weathered product granulite of porphyry, granite or syenite to use, which serve essentially as a lean agent, those according to the invention certain refractory clays are systematically added as binders.

Die Arbeitsweise geht damit von der mehr empirischen Anwendung des Radeburger Porphyrs zur systematischen Zuteilung von Bindemittel und Magerungsmittel über mit dem Vorteil, normenmäßige Backofen-Herdplatten zu schaffen, die weder sengen noch brennen.The way of working is based on the more empirical application of the Radeburger Porphyry for the systematic allocation of binders and lean agents with the advantage of creating standard oven hobs that do not scorch still burning.

Die Erfinder haben nämlich bei der Verwertung der obengenannten Rohstoffe die Erfahrung gemacht, daß sie besonders gute Eigenschaften für die Herstellung von Backofen-Herdplatten und für Schamottesteine für die Wangen und Gewölbe der Backöfen haben. Insbesondere fanden sie sie unempfindlich selbst beim schnellen Trocknen und Brennen, während sie an den fertigen Platten die guten Eigenschaften der Radeburger Platten wiederfanden, durch welche dieselben so bekannt, beliebt und allgemein verbreitet worden waren.Namely, the inventors have in the recovery of the above raw materials Experience has shown that they have particularly good properties for manufacture of oven hotplates and for firebricks for the cheeks and vaults of the Have ovens. In particular, they found them insensitive themselves during quick drying and firing, while working on the finished plates the good ones Found properties of the Radeburg plates, by which they are so well known popular and widespread.

Bei den modernen Dampfbacköfen sind die Backofenbauer dazu übergegangen, an Stelle der Backofen-Herdplatten in metallischen Rahmen eingeformte Kunststeinplatten zu verwenden.With modern steam ovens, the oven manufacturers have gone over to Artificial stone plates molded into metal frames in place of the oven hotplates to use.

Bäckermeister, welche beide Ofenarten nebeneinander betreiben, geben in bezug auf das Ausbacken dem alten Herdplatten-Backofen unbedingt den Vorzug.Master bakers who operate both types of ovens side by side When it comes to baking, the old stove top oven is definitely preferred.

Die nach dem vorliegenden Verfahren hergestellten Platten erlauben, zwecks Vermeidung der Kunstplatten, eine Sonderkonstruktion der Herdplatten. Bei dieser Arbeitsweise werden die Herdplatten, in genormten Rahmen und ebenfalls genormt, mittels Nut und Feder eingefügt, so daß wie bei den Kunstplatten lange Bahnen für Herde und Decken entstehen.The panels produced according to the present process allow In order to avoid the artificial plates, a special construction of the stove plates. at This way of working, the hotplates, in standardized frameworks and also standardized, inserted by means of tongue and groove, so that long tracks for Hearths and blankets are created.

Gegenüber den alten Backöfen mit ihren schweren Schamottegewölben hat eine solche Ausführung den Vorteil scheitrechter Decken mit gleichmäßiger Wärmestrahlung und Ausbackung für alle Teile des Ofens.Opposite the old ovens with their heavy chamotte vaults Such a design has the advantage of sloping ceilings with even heat radiation and baking for all parts of the oven.

Außer dem erklärten technischen Fortschritt macht die vorliegende Erfindung die Herstellung der Backofen-Herdplatten und mittelbar auch den Backofenbau unabhängig von einem einzigen Rohstoffvorkommen.In addition to the declared technical progress, the present Invention, the manufacture of the oven hotplates and indirectly also the oven construction regardless of a single raw material deposit.
