Abstract

After a surface pretreatment, an enamel slip (12) is applied to two vessel parts (10, 11) by spraying or dipping and subsequent predrying. The enamel is stripped off at the points (13, 14) intended for the welded joining of the two vessel parts (10, 11). The vessel parts (10, 11) are subsequently welded to each other. Enamel slip is applied to the welds by spraying or flooding. <IMAGE>

Description

Emaillierverfahren für geschlossene BehälterEnamelling process for closed containers

Gesehlossene Behälter mit relativ klelnen Anschlußöffnungen (Rohrstutzen bzw.Closed containers with relatively small connection openings (pipe socket respectively.

Muffen in Rohrstärke ) bringen erhebliche Probleme in der Emaillierungstechnik mit sich.Sockets in pipe thickness) cause considerable problems in enamelling technology with himself.

Die bekannten Verfahren der Email-Schlicker Aufbringung ( svässrige Suspension) durch Vakuum oder durch mechanische Einfüllung, durch teilweise oder ganzes Fluten und anschließende Drehbewegungen, sind bekannt. Diese Verfahren sind jedoch sehr arbeitsintensiv oder erfordern einen teueren apparativen Aufwand.The known methods of enamel slip application (aqueous Suspension) by vacuum or by mechanical filling, by partial or complete flooding and subsequent rotary movements are known. These procedures are however, they are very labor-intensive or require expensive equipment.

Gleichermaßen schwierig ist die Oberflächenvorbehandlung der Flächen, auf die Emaille aufgetragen werden soll, durch Entfetten, Beizen und Passivieren Das neue Verfahren soll die oben geschilderten Nachteile beheben und eine wirtschaftlichere Fertigung ermöglichen.Equally difficult is the surface pretreatment of the surfaces, on which the enamel is to be applied by degreasing, pickling and passivating The new process is intended to eliminate the disadvantages outlined above and to make it more economical Enable manufacturing.

Das Verfahren gemäß der Erfindung wird an Hand der Figuren 1-3 erklärt.The method according to the invention is explained with reference to FIGS. 1-3.

Der Behälter wird in zwei Teilkomponenten 10,11 hergestellt und in diesem Zustand oberflächenmäßig vorbehandelt ( entfettet, gebeizt, passiviert ).The container is produced in two sub-components 10, 11 and in Surface pretreated in this state (degreased, pickled, passivated).

Die Email-Schlicker wird im herkömmlichen Verfahren durch Spritzen oder Tauchen, auf die zwei Einzelkomponenten aufgebracht und vorgetrocknet.The enamel slip is made in the conventional process by spraying or dipping, applied to the two individual components and pre-dried.

An den zu verschweißenden Stellen 13,14 wird die Emaille in einem vorbestimmten Maß 15,16 ( Schweiß-Temperatur-Bereich ) abgestrichen.At the points to be welded 13, 14, the enamel is in one predetermined dimension 15,16 (welding temperature range).

Die Behälterteile werden anschließend automatisch ausgeführt.The container parts are then carried out automatically.

Um ein Ansehmelzen der aufgebrachten Emaille zu vermeiden, kann eine zusätzliche Kühleinrichtung im Bereich der Schweißnähte 17,18 angebracht werden.In order to prevent the applied enamel from melting, a additional cooling device can be attached in the area of the weld seams 17, 18.

Der so vorbereitete Behälter wird anschließend an den Stellen 13, 14 nachträglich mit Email-Schlicker durch Sprüh- oder Flutverfahren aufgebracht.The container prepared in this way is then placed at points 13, 14 subsequently applied with enamel slip by spraying or flooding.

Dor Trocknungsprozeß ist damit wesentlich verkürzt.The drying process is thus considerably shortened.

Auch der Trocknungsvorgang bei den eingangs erwähnten bekannten Verfahren, ist äußerst schwierig und energieaufwendig.Also the drying process in the known methods mentioned at the beginning, is extremely difficult and energy consuming.

Die gezeigte Darstellung über die konstruktive Ausbildung der Schweißnähte an den Stellen 13,14 ist nur eine von mehreren Möglichkeiten.The illustration shown about the structural design of the weld seams at points 13, 14 is only one of several possibilities.

Hauptkonstruktionsmerkmal für solche list: spaltfreie sqhweißtechnische Verbindung, die einen einwandfreien emai)technischeq Überzug gestattet.Main design feature for such list: gap-free sqhweißtechnischen Connection that allows a perfect emai) technical coating.
