Description

Gegenstand der Erfindung ist ein Verfahren zum Ziehen von Glasfäden aus der geschmolzenen Masse, bei dem die Fäden aus Düsen eines Schmelzgefäßes gezogen werden. Derartige Arbeitsverfahren sind bereits bekannt, haben jedoch sämtlich den Nachteil, daß die Fäden sehr oft abreißen, weil keine Möglichkeit besteht, die gesamte Glasmasse derart gleichmäßig zu erhitzen, daß an sämtlichen Düsen genauThe invention relates to a method for drawing glass filaments from the molten material A mass in which the threads are drawn from the nozzles of a melting vessel. Such Working methods are already known, but all have the disadvantage that the threads Tear off very often because there is no way of making the entire glass mass so evenly to heat that on all nozzles exactly

ίο gleiche Temperatur herrscht. Weder ist dies möglich durch Erhitzung des Schmelzbades mittels des elektrischen Stromes, der mit Hilfe ■ von Eintauchelektroden durch das Bad hindurchgeleitet wird, noch durch Beheizung, bei der das Schmelzgefäß selbst als Widerstandskörper dient, noch bei Schmelzverfahren, bei denen als Wärmequelle ein in einer Muffel im Schmelzbade angeordneter elektrischer Lichtbogen dient. Auch die Benutzung von Ölfeuerung, Gasfeuerung u. dgl. ermöglicht keine ganz gleichmäßige Wärmeverteilung. Stets wird das Glas stellenweise überhitzt, so daß Strömungen innerhalb der Schmelzmasse auftreten, oder die Schmelze kühlt sich an anderen Stellen zu stark ab, wodurch eine gleichmäßige Belieferung der Düsen verhindert wird und die Fäden abreißen.ίο the temperature is the same. Neither is this possible by heating the weld pool by means of the electric current that is generated with the help of ■ is passed through the bath by immersion electrodes, still by heating which the melting vessel itself serves as a resistance body, even in melting processes which, as a heat source, is an electric arc arranged in a muffle in the molten bath serves. The use of oil-fired, gas-fired and the like does not allow either very even heat distribution. The glass is always overheated in places, so that Currents occur within the melt mass, or the melt cools down on others Park too much, which prevents an even supply of the nozzles and the Tear off threads.

Gemäß vorliegender Erfindung werden diese Übelstände dadurch behoben, daß die Wärmezufuhr von elektrischen Widerstandsheizkörpern aus erfolgt, die, durch Rohre aus feuerfestem Material geschützt, im Innern der Glasmasse angeordnet sind. Hierdurch ist es ermöglicht, die Temperatur der Schmelze weitgehend zu regeln und vor allem die Temperatüren des gesamten Bades derart gleichmäßig zu halten, daß an sämtlichen Düsen die gleiche Temperatur herrscht. Dia Wärme wird sehr wirtschaftlich ausgenutzt, weil Strahlungsverluste fortfallen. Die genaue Einstellbarkeit der Beheizung ermöglicht es, die verschiedensten Glasarten zu behandeln und hierbei stets die geeignete Viskosität zu erzielen. Zweckmäßig liegt ein Teil der Heizrohre nahe an den Düsen.According to the present invention, these deficiencies are remedied that the heat supply from electrical resistance heating elements, which, through pipes made of refractory Material protected, are arranged inside the glass mass. This enables to largely regulate the temperature of the melt and, above all, the temperatures to keep the entire bath so evenly that the same on all nozzles Temperature prevails. The heat is used very economically because of radiation losses fall away. The exact adjustability of the heating enables the most diverse To treat types of glass and always to achieve the appropriate viscosity. A part of the heating pipes is expediently close by on the nozzles.
