Description
Vorrichtung zur Herstellung von Glasgegenständen, besonders zum Ziehen von Glastafeln. Die Oberfläche des auf mechanischem Wege durch Ziehen unmittelbar aus der geschmolzenen Glasmasse herge§tellten Tafelglases weist parallel zur Ziehrichtung verlaufende Streifen auf. Die Ursache davon liegt bekanntlich hauptsächlich darin, daß die flüssige Glasmasse an den Schamottewandungen der Maschine ein Aluminiumsilikat erzeugt, welches eine zähflüssige Tonglasur bildet. Diese besitzt eine andere Viskosität und einen anderen Lichtbrechungskoeffizienten als die eigentliche Glasmasse, von welcher sie mitgerissen wird, so daß sie in der Glastafel in Form von Längsfäden und Streifen erscheint.Device for the production of glass objects, especially for drawing of glass panels. The surface of the mechanically by pulling directly Sheet glass made from the molten glass mass points parallel to the direction of drawing running stripes. As is well known, the main reason for this is that the liquid glass mass on the fireclay walls of the machine is an aluminum silicate which forms a viscous clay glaze. This has a different viscosity and a different refractive index than the actual glass mass, of which it is carried along, so that it is in the glass sheet in the form of longitudinal threads and stripes appear.
Es wäre zweckmäßig, die von der flüssigen Glasmasse berührten Wände der Apparatur aus einem Material herzustellen, welches von der Glasmasse nicht angegriffen wird. Hierzu würden sich einige Metalle eignen, diese können jedoch wegen der Wärmeableitung hier nicht verwendet werden. Ähnliches gilt von der ebenfalls bereits vorgeschlagenen Bekleidung der Wände von Glasschmelzöfen mit Platinblechen.It would be useful to have the walls touched by the liquid glass mass the apparatus made of a material that is not attacked by the glass mass will. Some metals would be suitable for this purpose, but these can be used because of the heat dissipation not used here. The same applies to the one that has already been proposed Clad the walls of glass melting furnaces with platinum sheets.
Gemäß der vorliegenden Erfindung werden die von der flüssigen Glasmasse berührten Schamotteflächen der Apparatur auf galvanischem oder chemischem Wege oder durch das Spritzverfahren oder andere Weise mit fein verteiltem Metall überzogen. Das Metall darf bei der dort herrschenden Temperatur (etwa 9oo°) nicht schmelzen und von der Glasmasse chemisch nicht angegriffen werden, wie z. B. Nickel. Wesentlich ist dabei, daß an den Schamottewandungen ein festhaftender Metallüberzug gebildet wird, welcher im Gegensatz zu der bekannten Blechbekleidung so dünn ausgeführt werden kann, daß die Nachteile der Wärmeableitung praktisch gar nicht hervortreten und welcher nach Beschädigung wieder leicht und billig erneuert werden kann, was bei den bekannten Blechbekleidungen ebenfalls nicht der Fall ist.According to the present invention, the liquid glass mass touched chamotte surfaces of the apparatus by galvanic or chemical means or coated with finely divided metal by spraying or other means. The metal must not melt at the temperature there (around 900 °) and are not chemically attacked by the glass mass, e.g. B. Nickel. Essential is that a firmly adhering metal coating is formed on the firebrick walls which is made so thin in contrast to the known sheet metal cladding can that the disadvantages of heat dissipation practically do not emerge and which can be easily and cheaply renewed after damage, what at the known sheet metal cladding is also not the case.
Berührt nun die flüssige Glasmasse keine nackten Schamotteteile, sondern nur Metallflächen, so unterbleibt die Bildung von Aluininiumglasuren und damit die Verunreinigung der Glasmasse und die Streifenbildung in den Glaswaren.If the liquid glass mass does not touch bare fireclay parts, but rather only metal surfaces, so the formation of aluminum glazes and thus the Contamination of the glass mass and the formation of streaks in the glassware.
