Description
EinbrennofenStoving oven
Zum Zwecke des Einbrennens von metallischen oder glaskeramischen Schichten, sowie Farben auf Keramik-, Glas- oder Emailleträger wer den elektrisch beheizte Öfen verwendet, bei denen die Temperatur mittels eines, meist elektronischen Reglers konstant gehalten wird.For the purpose of baking metallic or glass-ceramic layers, as well as colors on ceramic, glass or enamel supports who are electrically heated Furnaces used in which the temperature is controlled by means of a controller, usually electronic is kept constant.
Um gleichmäßige und reproduzierbare Eigenschaften der eingebrannten Schichten zu erzielen, ist nicht nur die Temperaturkonstanz, sondern auch der Zeitverlauf der Temperatur während dem Aufheizen und Abkühlen der Teile (Aufschmelz- und Rekri6tallisationsphase)von Bedeutung. In manchen Fällen erfolgt das Einbrennen im Schutzgas unter Ausschluß von Sauerstoff oder Wasserdampf.To ensure uniform and reproducible properties of the branded Achieving layers is not only a matter of temperature constancy, but also the passage of time the temperature during the heating and cooling of the parts (melting and recrystallization phase) of Meaning. In some cases the stoving takes place in the protective gas with exclusion of oxygen or water vapor.
Es sind Durchlauföfen bekannt, die mehrere, auf verschiedenen Temperaturen geregelte Zonen aufweisen. Die einzubrennenden Teile werden auf einem Gurt gelegt, der die Teile durch die verschiedenen Zonen transportiert. Durch Einstellen der Transportgeschwindigkeit des Gurtes, kann die gewünschte Aufheiz-, Verweil- und Abkühlzeit (Temperatur-Profil) erreicht werden. Die Heizelemente solcher Ofen weisen eine große thermische Masse auf. Das Temperatur-Profil kann nur in bestimmten Grenzen eingestellt werden. Eine Veränderung der Tmperatur erfordert mehrere Stunden Einschwingzeit. Die Öfen müssen im Dauerbetrieb laufen, verbrauchen dabei mehrere Kilowattstunden Strom, Kühlwasser und Druckluft und sind nur bei einer Dauerauslastung wirtschaftlich. Außerdem sind solche Öfen meist mehrere Meter lang und bedürfen eine kostspielige Installation. Zum Erstellen von Prototypen oder Kleinserien, insbesondere wenn verschiedene Einbrenntemperaturen notwendig sind, Xst das Arbeiten mit solchen Öfen umständlich und unwirtschaftlich.There are continuous ovens known that several, at different temperatures have regulated zones. The parts to be burned in are placed on a belt, that transports the parts through the different zones. By setting the Transport speed of the belt, the desired heating, dwell and Cooling time (temperature profile) can be achieved. The heating elements of such ovens have a large thermal mass. The temperature profile can only be used within certain limits can be set. A change in temperature requires several hours of settling time. The ovens have to run continuously and consume several kilowatt hours Electricity, cooling water and compressed air are only economical if they are used continuously. In addition, such ovens are usually several meters long and require an expensive one Installation. For creating prototypes or small batches, especially if different Baking temperatures are necessary, so working with such ovens is cumbersome and uneconomical.
Weiterhin sind Öfen bekannt, die als Heizelement Infrarotstrahler benutzen. Die Infrarotstrahler besitzen eine geringe thermische Masse, benötigen zum Erreichen der gewünschten Temperatur nur Bruchteile der Sekunde und müssen nicht im Dauerbetrieb laufen. Dadurch benötigen sie einfachere Kühlung und weniger Energie. Auch eine schnelle Xnderung des Temperaturprofils ist möglich. Solche Öfen weisen jedoch folgenden Nachteil auf: Das Strahlungsmaximum der Infrarotstrahler liegt, je nach Temperatur bei einer Wellenlänge zwischen 1000 und 2500 nm. Für diese Wellenlängen sind die meisten Keramiken durchsichtig. Es findet nur eine geringe Energieabsorption und dadurch eine geringe Erwärmung statt. Metalle dagegen absorbieren die Energie der Infrarotstrahlung fast vollständig und erwärmen sich dadurch wesentlich stärker. Beim Einbrennen von Keramikteilen, versehen mit strukturierten Schichten aus metallhaltigen oder glaskeramischen Pasten. oder Farben in einem Infrarotofen, tritt eine ungleichmäßige Erwärmung der Teile in Abhängigkeit von der Beschaffenheit der Schicht und der Gesamtfläche der Struktur auf. Das Erwärmen von Teilen, versehen mit Schichten verschiedener Beschaffenheit und Struktur auf eine gleiche, reproduzierbare Temperatur ist mit solchen Öfen nicht möglich.Furthermore, ovens are known that use infrared radiators as heating elements use. The infrared emitters have a low thermal mass and need to reach the desired temperature only fractions of a second and do not have to run in continuous operation. As a result, they require easier cooling and less energy. A quick change in the temperature profile is also possible. Such ovens show however, has the following disadvantage: The radiation maximum of the infrared radiator is depending on the temperature at a wavelength between 1000 and 2500 nm. Most ceramics are transparent for these wavelengths. It just finds low energy absorption and, as a result, low heating. Metals on the other hand absorb the energy of the infrared radiation almost completely and heat up much stronger as a result. When firing ceramic parts, provided with structured layers of metal-containing or glass-ceramic pastes. or colors In an infrared oven, uneven heating of the parts occurs depending on on the nature of the layer and the total area of the structure. The warming of parts, provided with layers of different nature and structure an identical, reproducible temperature is not possible with such ovens.
Die Erfindung zeigt einen stationären Einbrennofen, der die Nachteile der bekannten Öfen nicht aufweist, relativ wenig Energie verbraucht und eine hohe Temperatur konstanz aufweist. Die Erfindung geht aus einem, mit Infrarotstrahlern beheizten Ofen aus, in dem eine hitzebeständige Metallplatte die Infrarotenergie absorbiert und in Wärme umsetzt. Die einzubrennenden Teile werden durch diese Platte von der direkten Infrarotstrahlung abgeschirmt. Die Temperatur der Platte wird durch einen elektronischen Präzisionsregler mit einer Zeit-Temperatur-Steuerung geregelt. Die Platte befindet sich in einer Kammer1 die die Teile von der Atmosphärenluft abschirmt und mit einem beliebigen Gas (z.B. Inertgas) gespült werden kann.The invention shows a stationary baking oven that has the disadvantages of the known ovens does not have, consumes relatively little energy and a high Temperature has constant. The invention is based on one, with infrared radiators heated oven in which a heat-resistant metal plate absorbs infrared energy absorbed and converted into heat. The parts to be burned in are through this plate shielded from direct infrared radiation. The temperature of the plate is through an electronic precision regulator with a time-temperature controller. The plate is located in a chamber 1 which removes the parts from the atmospheric air shielded and can be purged with any gas (e.g. inert gas).
Die Erfindung wird im folgenden auf Grund eines in der Zeichnung schematisch dargestelltem Ausführungsbeispielsnäher erläutert: Die Metallplatte 1 wird durch die Strahlung der Infrarotstrahler 2 erwärmt. Die Temperatur der Platte wird durch den Temperaturgeber 3 aneiner oder mehreren Stellen gemessen und an dea Regler 4 übermittelt.The invention is illustrated below on the basis of one in the drawing illustrated exemplary embodiment explained in more detail: The metal plate 1 is through the radiation of the infrared heater 2 is heated. The temperature of the plate is through the temperature sensor 3 measured at one or more points and on the controller 4 transmitted.
Der Regler 4 steuert die Leistung der Infrarotstrahler 2 so, daß sich der eingestellte Zeit-Temperaturverlauf ergibt. Beim Abkühlen wird durch den Regler 4 ein Kühlgebläse 5 so geregelt, daß der eingestellte Zeit-Temperaturverlauf eingehalten wird. Die Kammer 6, die sinnvollerweise aus einem, für die Infrarotstrahlung transparentem Werkstoff besteht, ist so gebildet, daß die Platte 1 vollständig eingeschlossen ist. Die Ein- und Austritte 7 und 8 ermöglichen die Spült lung der Kammer mit einem bestimmten Gas.The controller 4 controls the power of the infrared heater 2 so that the set time-temperature curve results. When cooling down, the regulator 4 a cooling fan 5 controlled so that the set time-temperature curve is maintained will. The chamber 6, which usefully consists of a transparent for the infrared radiation Material is formed so that the plate 1 is completely enclosed is. The inlets and outlets 7 and 8 allow the chamber to be flushed with a certain gas.
