Abstract

The tube and plunger for use in the feeder process for making molten glass lumps for the prodn. of hollow glass objects are, with the view of yielding uniform temp. lumps electrically heated and/or consist of two or several parts, which are assembled end-on axially.

Description

Glastropfen für das Speiserverfahren.Glass drops for the riser process.

Die Erfindung betrifft eine Vorrichtung zur Erzielung eines gleichmäßig temperierten Glastropfens für die Herstellung von Hohlglasgegenständen. Vor allem bei Hohlglasgegenständen, die im Blas-Blas-Verfahren hergestellt werden, ist ein Glastropfen mit gleichmäßiger Temperatur erforderlich, da sonst durch schlechte Glasverteilung mit Festigkeitseinbußen und Verformungen der gefertigten Glasartikel gerechnet werden muß.The invention relates to a device for achieving a uniform tempered glass gob for the production of hollow glass objects. Above all in the case of hollow glass objects that are manufactured using the blow-and-blow process, a Glass drops with a constant temperature required, otherwise bad Glass distribution with loss of strength and deformation of the manufactured glass articles must be expected.

Es ist bekannt, daß zur Erreichung dieser gleichmäßigen Temperatur die verschiedensten Vorrichtungen und Heizsysteme eingesetzt sind0 Die Temperatur im Speiserkanal wird zum Beispiel durch Rühren des Glases oder Veränderung des ganalquerschnittes beeinflußt, Man installiert zusztliche elektrische Beheizungen zur meist vorhandenen GasbeheizungO Diese Vorrichtungen sind jedoch nur für die Beeinflussung der Glastemperatur im zum Speiserkopf führenden Kanal wirksam0 Messungen haben gezeigt, daß im Speiserkopf die eigentliche Ursache für die ungleichmäßige Tropfentemperatur zu finden ist. Wenn man annimmt, daß im Speiserkopf das Glas mit annahernd gleicher Viskosität und damit gleicher Temperatur anlangt, so erfolgt hier durch Rohr und Plunger eine Abkühlung des Glases, die im Tropfen ungleichmäßige Temperaturen hervorruft die durch nachfolgende Beheizung nicht mehr berichtigt werden können, Der erfindung liegt die Aufgabe zugrunde in Rohr und Plunger den Wärmefluß aus dem Glas zu vermindern oder zu vermeiden.It is known that to achieve this uniform temperature A wide variety of devices and heating systems are used 0 The temperature in the feeder duct, for example, by stirring the glass or changing the duct cross-section influences, one installs additional electrical heating to the mostly existing ones Gas heatingO These devices are only for influencing the glass temperature Effective in the channel leading to the feeder head0 Measurements have shown that in the feeder head the real cause of the uneven drop temperature is to be found. If one assumes that the glass in the feeder head has approximately the same viscosity and thus the same temperature is reached, one takes place here through the pipe and plunger Cooling of the glass, which causes uneven temperatures in the drop can no longer be corrected by subsequent heating, The invention The underlying task is to reduce the flow of heat from the glass in the pipe and plunger or to avoid.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß Rohr und Plunger aus mindestens zwei Teilen zusammengesetzt sind, wobei der INärmefluß zwischen den Teilen durch geeignete Maßnahmen stark gemindert wird. Zur Verhinderung des Wärmeflusses werden Rohr und Plunger vorzugsweise elektrisch beheizt.This object is achieved according to the invention in that tube and Plungers are composed of at least two parts, with the flow of heat between the parts is greatly reduced by suitable measures. To prevent the The pipe and plunger are preferably heated electrically due to the flow of heat.

Der mit der Erfindung erzielte Vorteil besteht darin, daß gleichmäßig temperiertes Glas aus dem Tropfring austritt. Im Falle der elektrischen beheizung von Rohr und Plunger ergibt sich dieMöglichkeit Wärme zum Glas fließen zu lassen und damit die Temperatur in einer bis heute nicht bekannten Weise zu steuern.The advantage achieved by the invention is that evenly tempered glass emerges from the drip ring. In the case of electric heating The pipe and plunger provide the opportunity to let heat flow to the glass and thus to control the temperature in a manner not known until now.
