Description

Es sind bereits Verfahren und Vorrichtungen bekannt, durch die beim Verzinnen von Gegenständen das überflüssige Metall durch auf die letzteren geblasene Luft oder Gas entfernt wird. Bei diesen bekannten Verfahren und Vorrichtungen wird das Beblasen der Gegenstände aber unmittelbar nach dem . Verlassen des Metallbades vorgenommen, wodurch die Verzinnung für gewisse Zwecke aber nicht nur zu stark, sondern auch stumpf und unansehnlich wird.There are already methods and devices known by the tinning of objects the superfluous metal by air blown on the latter or Gas is removed. In these known methods and devices, the blowing is but of the objects immediately after. Leaving the metal bath made, whereby the tinning for certain purposes is not only too strong, but also dull and unsightly.

Um nun die bisher mit den bekannten Einrichtungen erzielte begrenzt dünne Verzinnung noch dünner zu gestalten bzw. auf einTo now the limited thin tinning achieved so far with the known devices to make it even thinner or on one

!5 äußerst zu erreichendes Maß herabzudrücken, also möglichst an Zinn zu sparen, und eine schöne und glänzende Oberfläche zu erzielen, ohne die Brauchbarkeit der Gegenstände zu beeinträchtigen, werden gemäß vorliegender Erfindung die zu verzinnenden Blechtafeln oder Bänder erst dann mit heißer Druckluft beblasen, nachdem dieselben das auf dem Zinnbade schwimmende Fettbad verlassen haben, wobei das Fett nicht nur als Flußmittel dient und Oxydation verhindert,'sondern auch das an den Gegenständen befindliche Zinn leicht flüssiger macht und ein leichteres und gleichmäßigeres Abblasen ermöglicht.! 5 to press down the extremely attainable amount, so to save as much tin as possible, and to achieve a beautiful and shiny surface, without affecting the usefulness of the items, are in accordance with the present Invention of the metal sheets or strips to be tinned only then with hot compressed air blow them after they have left the fat bath floating on the tin bath, the fat not only acting as a flux and preventing oxidation, but also that The tin on the objects makes it slightly more fluid and a lighter and more uniform one Blowing off allows.

In beiliegender Zeichnung ist eine zur Ausführung des Verfahrens dienende Vorrichtung im senkrechten Schnitt dargestellt.In the accompanying drawing is a device used to carry out the method shown in vertical section.

d ist der bekannte Kessel mit dem Zinnbade, e ist der Fettkessel mit dem geschmolzenen heißen Fett, welches auf dem Zinnbade schwimmt, und/, /, /, / sind vier Stahlwalzenpaare, welche die Blechtafel g nach Verlassen des Zinnbades durch das Fettbad nach außen befördern. d is the well-known kettle with the tin bath, e is the fat kettle with the molten hot fat, which floats on the tin bath, and /, /, /, / are four pairs of steel rollers, which the sheet g after leaving the tin bath to the outside through the fat bath promote.

Unmittelbar nach Verlassen des. Fettbades wird die Blechtafel mittels der über dem obersten Walzenpaare angeordneten Düsen h, welche die Breite der Blechtafel besitzen, mit heißer Druckluft beblasen, wodurch nicht nur, wie eingangs erwähnt, eine äußerst dünne Verzinnung sowie eine Entfettung der Blechtafel erreicht wird, sondern auch eine schöne und glänzende Oberfläche auf den verzinnten Gegenständen erzielt wird.Immediately after leaving the grease bath, the metal sheet is blown with hot compressed air by means of the nozzles h, which are arranged above the uppermost roller pair and which have the width of the metal sheet, whereby not only, as mentioned above, an extremely thin tinning and degreasing of the metal sheet is achieved , but also a beautiful and shiny surface is achieved on the tinned objects.
