Description
Emaillierte Gegenstände Die Erfindung betrifft emaillierte Gegenstände, die aus emaillierten Einzelteilen zusammengesetzt sind. Der Zusammenbau solcher Einzelteile zu einem komplizierten emaillierten Gegenstand erforderte bisher sehr umständliche und teure Behelfskonstruktionen. Die Befestigung erfolgte z. B. durch emaillierte Knebelverbindungen, wobei die Einschraubstellen durch einen beständigen Kitt wieder abgedichtet werden mußten, oder durch Schraub- und Nietverbindungen aus Metallen bzw. Legierungen, die der Einwirkung des betreffenden korrodierenden Mediums widerstehen, wobei man an den Auflagestellen ebenfalls geeignete Dichtungsmaterialien verwenden mußte, um zu verhüten, daß das Medium das Grundmetall der emaillierten Teile angreift. Eine Verbindung der emaillierten Einzelteile durch außen angebrachte Bügel, Klammern o. dgl. ist nicht angängig, da diese Vorrichtungen keine einwandfreie unbewegliche Befestigung bewirken, sondern zur Federung neigen.Enamelled objects The invention relates to enamelled objects, which are composed of enamelled individual parts. The assembly of such Individual parts for a complicated enamelled object used to be very demanding cumbersome and expensive makeshift constructions. The attachment took place z. B. by enamelled toggle connections, the screw-in points through a permanent Putty had to be sealed again, or by screw and rivet connections of metals or alloys exposed to the action of the corrosive in question Resist medium, with one also suitable sealing materials at the support points had to use to prevent the medium from being the base metal of the enamelled Attacks parts. A connection of the enamelled individual parts through externally attached Brackets, brackets or the like is not applicable, since these devices are not flawless cause immovable attachment, but tend to spring.
Es wurde nun gefunden, daß die Schwierigkeiten und Unvollkommenheiten im Zusammenbau der emaillierten Einzelteile behoben werden, wenn die Einzelteile gemäß der Erfindung durch eine Emailschicht miteinander verbunden sind. Ein Verfahren zum Herstellen der aus den Einzelteilen zusammengesetzten Gegenstände besteht erfindungsgemäß darin, daß zunächst die Einzelteile fertig emailliert werden und diese in der gewünschten Weise zusammengesetzt bis zur Erweichungstemperatur des Emails erhitzt werden, wobei gegebenenfalls an den Berührungsstellen der Einzelteile ein zusätzlicher Emailauftrag vor der Erhitzung aufgebracht werden kann. Durch die Erhitzung bis zur Erweichungstemperatur findet ein Zusammenfließen der sich berührenden Emailschichten statt. Der gegebenenfalls zusätzliche Emailauftrag an den Berührungspunkten der Einzelteile bewirkt eine verstärkte Verbindung der Einzelteile.It has now been found that the difficulties and imperfections in the assembly of the enamelled items are fixed when the items according to the invention are connected to one another by an enamel layer. A procedure according to the invention for producing the objects assembled from the individual parts in that first the individual parts are enamelled and these in the desired Assembled way to be heated up to the softening temperature of the enamel, whereby if necessary, an additional email order at the contact points of the individual parts can be applied before heating. By heating up to Softening temperature there is a confluence of the enamel layers in contact. The possibly additional enamel application at the points of contact of the individual parts results in increased Connection of the individual parts.
Allerdings darf die Anhäufung von Email an den Verbindungsstellen nur so groß sein, daß eine Gefahr des Abplatzens der Emailschicht nicht besteht.However, the accumulation of email at the connection points is allowed only be so large that there is no risk of the enamel layer flaking off.
Da beim Zusammenbau der Einzelteile die Massenverteilung meist sehr ungleich wird, ist bei der Durchführung des Glühprozesses darauf zu achten, daß Aufheiz- und Abkühlvorgang langsam und gleichmäßig erfolgen, damit keine schädlichen Spannungen an den Verbindungsstellen der Einzelteile auftreten.Because when assembling the individual parts, the mass distribution is usually very high becomes unequal, care must be taken when carrying out the annealing process that The heating and cooling process should be carried out slowly and evenly so that there are no harmful effects Tensions occur at the connection points of the individual parts.
Ein gemäß der Erfindung aus emaillierten Einzelteilen zusammengesetzter Gegenstand ist beispielsweise ein Destillierkolonnenboden mit Glocken. Es ist ohne weiteres möglich, Boden und Glocken einzeln einwandfrei zu emaillieren, wenn die für eine Emaillierung geltenden Bedingungen, wie Werkstoffzusammensetzung, richtige Querschnittsverteilung und Übergänge sowie die erforderlichen Abrundungen, beachtet werden. Da nun aber die Glocken nicht lose auf dem Boden eingebaut werden dürfen, weil durch die im Betrieb auftretenden Vibrationen das Email an d°n Berührungsstellen zerstört würde, setzt man die einzelnen Teile, nachdem sie auf Porenfreiheit mit den üblichen Verfahren geprüft sind, in der gewünschten Lage zusammen und unterzieht sie einer Glühung bis zur Erweichungstemperatur des Emails, wodurch die Emailschichten von Boden und Glocken an ihren Auflagestellen zusammenfließen.An assembled according to the invention from enamelled individual parts The subject is, for example, a distillation column tray with bells. It is without It is also possible to enamel the base and bells individually, if the Conditions applicable to enamelling, such as material composition, are correct Cross-sectional distribution and transitions as well as the required rounding are observed will. But since the bells must not be installed loosely on the floor, because the vibrations that occur during operation cause the enamel at the points of contact would be destroyed, the individual parts are set after they are free of pores The usual procedures are examined, put together and subjected to the desired location they anneal up to the softening temperature of the enamel, whereby the enamel layers of the floor and bells flow together at their contact points.
