Description

Einrichtung an Muffelöfen Die Brennöfen zum Aufschmelzen des Emails werden mit Muffeln versehen, die bisher aus Schamotte oder Siliciumcarbid hergestellt werden. Diese Muffeln haben den Nachteil, daß nur ein geringer Teil der in den Gasen der Feuerung zur Verfügung stehenden Wärme nach dem Innern der Muffeln gesendet wird, da die Ausstrahlung von Schamotte und Siliciumcarbid nur gering ist. Der Nutzeffekt solcher Feuerungen ist daher gering, Es wurde wohl versucht, Muffeln aus Eisen herzustellen, doch haben sich diese nicht bewährt, da sie sich leicht verziehen, springen und verbrennen. Ein Austauschen der Muffeln ist mit großen Kosten und mit einem bedeutenden Zeitaufwand verbunden. -Diese Nachteile werden erfindungsgemäß dadurch beseitigt, daß die Muffeln aus Schamotte, "Siliciumcarbid o. dgl. mit Fenstern versehen werden, in die Platten aus hitzebeständigem Metalleingesetzt werden. Hitzebeständiger Stahl eignet sich hierfür in besonderer Weise. Die Strahlung der Wandung der so ausgestalteten Muffeln ist .eine wesentlich höhere, so daß sich die Arbeit wirtschaftlicher gestaltet und die Brenndauer verkürzt werden kann.Equipment on muffle furnaces The furnace for melting the enamel are provided with muffles that were previously made of chamotte or silicon carbide will. These muffles have the disadvantage that only a small part of the in the gases The heat available to the furnace is sent to the inside of the muffles because the appearance of chamotte and silicon carbide is only slight. The benefit such furnaces are therefore small. Attempts have been made to make muffles out of iron, but these have not proven themselves, as they are easily warped, jumped and burn. Replacing the muffles is costly and significant Time expenditure connected. -These disadvantages are eliminated according to the invention by that the muffles made of fireclay, silicon carbide or the like are provided with windows, are inserted into the plates made of heat-resistant metal. Heat-resistant steel is particularly suitable for this. The radiation of the wall of the so designed Grouching is .a much higher, so that the work is more economical and the burning time can be shortened.

Das Belegen der Muffeln mit den Stahlplatten geschieht zweckmäßigerweise derart, daß die einzelnen Stücke, aus welchen die Muffeln zusammengesetzt werden, außen mit Nuten versehen werden, in die man die Platten einschiebt. Werden diese Nuten entsprechend weit gehalten, so kann ein Verklemmen der Platten nicht stattfinden und eine gründliche Durchlüftung der Muffel erfolgen. Beim Arbeiten mit der Muffel wird zweckmäßigerweise die Sekundärluft gedrosselt. .Statt Nuten können auch Nasen verwendet werden, welche die Metallplatten örtlich festhalten.The covering of the muffles with the steel plates is expedient in such a way that the individual pieces from which the muffles are assembled be provided with grooves on the outside into which the panels are inserted. Will this Grooves are kept wide enough to prevent the panels from jamming and thorough ventilation of the muffle. When working with the muffle the secondary air is expediently throttled. Instead of grooves, noses can also be used can be used, which hold the metal plates in place.

In der Zeichnung ist ein Ausführungsbeispiel dargestellt. Die Abb. i zeigt einen Querschnitt durch die Muffel. Die Abb. 2, 3 und 4. zeigen ein Bauelement der Muffel in einer Ansicht in zwei Schnitten. i stellt einen solchen Teil dar, der mit Nuten z versehen ist, in welche- der Belag 3 eingeschoben wird. In Abb.2 zeigt die strichpunktierte Lage der Platte den Vorgang beim Auswechseln der Platten.An exemplary embodiment is shown in the drawing. Fig. i shows a cross section through the muffle. Figs. 2, 3 and 4 show a component the muffle in a view in two sections. i represents such a part which is provided with grooves z into which the covering 3 is pushed. In Fig 2 The dot-dash position of the plate shows the process when changing the plates.
