Description

Gegenstand der Erfindung ist ein Verfahren zum Einbrennen der Emailschicht auf Kupfer-, Messing- und Zinkplatten. Das heutige übliche Verfahren besteht darin, daß die Metallplatte mit einer emailähnlichen Leimschicht überzogen und diese nach dem Belichten und Entwickeln durch Erhitzen über einer Gasflamme aufgebrannt wird. Dieses Einbrennen der Emailschicht vonThe invention relates to a method for burning in the enamel layer Copper, brass and zinc plates. The current practice is that the metal plate covered with a layer of glue similar to enamel and this after Exposure and development is burned on by heating over a gas flame. This burning in the enamel layer of

ίο unten über der Gasflamme durch das Metall durch, wozu eine Wärme von etwa 3000 erforderlich ist, verursacht eine kristallinische Umbildung der Metalle, was in erster Linie bei Zink festzustellen ist, wodurch dessen ursprüngliche Härte auf ein Minimum herabgedrückt wird. Die ungleichmäßige Ausdehnung durch das einseitige Beheizen über der offenen Flamme sowie Lufteinfluß (insbesondere Sauerstoff), Zug und Staub verursachen minderwertige oder oft unbrauchbare Ätzungen.ίο through the metal below above the gas flame, for which a heat of about 300 0 is required, causes a crystalline transformation of the metals, which can be seen primarily with zinc, whereby its original hardness is reduced to a minimum. The uneven expansion caused by one-sided heating over an open flame as well as the influence of air (especially oxygen), drafts and dust cause inferior or often unusable etchings.

Gemäß der Erfindung wird die zum Einbrennen der Kopierschicht bestimmte Platte auf eine die Wärme schlecht leitende Unterlage, . z. B. Asbest, gelegt und über die in solcher Weise vorbereitete Platte ein flammloser Heizgasstrom von der zum Emaillieren erforderlichen Temperatur von etwa 3000 geleitet. Infolge der Benutzung eines flammlosen Heizgasstromes erfolgt die Beheizung sozusagen mit unendlich großer Flamme. Lokale Überhitzüngen und ungleichmäßige Aus-According to the invention, the plate intended for burning in the copying layer is placed on a base that is poorly conductive to heat,. z. B. Asbestos, placed and passed a flameless flow of heating gas from the temperature of about 300 0 required for enamelling over the plate prepared in this way. As a result of the use of a flameless heating gas flow, the heating takes place with an infinitely large flame, so to speak. Local overheating and uneven heating

dehnung ist ausgeschlossen. Durch das Auflegen der Metallplatte beim Emaillieren auf eine die Wärme schlecht leitende Masse einesteils und anderenteils durch den über die Metallplatte streichenden flammenlosen Heizgasstrom vollzieht sich das Einbrennen der Emailschicht ohne wesentliche Erwärmung der Metallplatte, wodurch viele Nachteile, die den Metallätzungen, welche nach dem alten Istretching is excluded. By placing the metal plate on when enamelling a heat poorly conductive mass on the one hand and on the other part through the over the The flameless flow of heating gas, which paints a metal plate, is burned in Enamel layer without significant heating of the metal plate, eliminating many disadvantages that the metal etchings, which according to the old I.

Die Zeichnung veranschaulicht eine Vorrichtung zur Ausübung dieses Verfahrens in zwei Bildern.The drawing illustrates an apparatus for practicing this method in FIG two pictures.

α ist der Ofenraum, der durch den Schieber b verschließbar ist. c ist eine auf Rollen einschiebbare Ofenplatte. Diese Platte c ist dick mit Asbest belegt, Die Beheizung des Ofenraumes α erfolgt durch die kleinen Flämmchen d, die das Ofengut nicht berühren und nur einen durch den Ofen ziehenden Heizgasstrom von z. B. 300° erzeugen. Die dünnen Metallplatten werden so auf die Asbestschicht der Einschiebeplatte c gelegt, daß die Emailschicht oben liegt. Der Heizgasstrom erhitzt jetzt zuerst die Emailschicht, und zwar völlig gleichmäßig. Die Emailschicht ist daher schon eingebrannt, ehe das Metall die Ofentemperatur erreicht. α is the furnace space that can be closed by the slide b . c is a sliding oven plate on castors. This plate c is thickly covered with asbestos. The furnace space α is heated by the small flames d, which do not touch the furnace material and only a flow of heating gas of z. B. produce 300 °. The thin metal plates are placed on the asbestos layer of the insert plate c so that the enamel layer is on top. The flow of heating gas now first heats the enamel layer, and does so completely evenly. The enamel layer is therefore already burned in before the metal reaches the furnace temperature.
