| Zusammenfassung: | The invention relates to a device for temperature equalisation in a glass first rendered flowable in a melting furnace. The invention is based on a device in which molten glass in feeder channels made of metal, preferably platinum or platinum alloys, is heated by the direct passage of current through the platinum metal from a controllable current source. According to the invention, feeder electrodes are assigned to the metal tube which are connected to the contact rings semilaterally so as to form a closed circuit. |
