Abstract

A stirrer or plunger tool, for molten glass, consists of precious and/or non-precious metal and has one or more cooling channels. Suitable precious metals are Pt, Rh, Pd, Au, Ag, Ru, Ir and Os or their alloys or combinations and suitable non-precious metals are Ni, Fe and Cr or their alloys or combinations. Stabilisation of the cooling channels may be achieved by rods, strips, sheets, honeycombs or other cross-sectional shapes; stabilisation of the tool interior may be achieved by provision of water, air and/or gas cooling; and stabilisation of precious metal tools may be achieved by quartz glass or zirconia.

Description

Die Erfindung bezieht sich auf Vorrichtungen zum Verrühren und/oder portionsweisem Ausstoßen von geschmolzenem Glas.The invention relates to devices for stirring and / or Ejecting molten glass in portions.

Um homogene, schlierenfreie Gläser herzustellen, finden Stirrergeräte Anwendung, mit denen das Glas in zähflüssigen Zustand gerührt und durchgemischt wird.Stirrer devices are used to produce homogeneous, streak-free glasses Application with which the glass is stirred and viscous is mixed.

Weiterhin werden Plungergeräte dazu benutzt, die Glasmasse in Form von Tropfen nach unten in automatisch arbeitende Maschinen geführt wird.Furthermore, plunger devices are used to the glass mass in the form of Drop is led down into automatically working machines.

Es ist bekannt, daß oben erwähnte Geräte aus reinem Platin und/oder Pla­ tiniegierungen hergestellt werden. Desweiteren sind Geräte bekannt, die als Kernmaterial Molybdän, Wolfram oder Legierungen beider mit einem Überzug aus Platin oder Platinlegierungen versehen sind.It is known that the above-mentioned devices made of pure platinum and / or Pla Alloys are manufactured. Furthermore, devices are known which as core material molybdenum, tungsten or alloys of both with one Platinum or platinum alloy coating are provided.

Dieselben haben den Nachteil ungenügender Festigkeit bei hohen Tempe­ raturen als auch zu kostenintensiv zu sein. Im Falle von Kernmaterialien mit Platinüberzug besteht der Nachteil in der Möglichkeit einer Undich­ tigkeit bei Verlust des Vakuums.These have the disadvantage of insufficient strength at high temperatures repairs as well as being too expensive. In the case of core materials with platinum plating, the disadvantage is the possibility of a leak action when vacuum is lost.

Durch die Erfindung werden die Mängel der bekannten Geräte auf zweckmäßige Weise vermieden. The invention addresses the shortcomings of the known devices appropriately avoided.  

Gemäß der vorliegenden Erfindung bestehen die in Berührung mit dem geschmolzenen Glas stehenden Geräteteile aus
A) Edelmetallen wie Pla­ tin, Rhodium, Palladium, Gold, Silber, Ruthenium, Iridium, Osmium bzw. deren Legierungen oder aus Kombinationen dieser Werkstoffe,
B) Nicht-Edelmetalle wie Nickel, Eisen und Chrom bzw. deren Legierun­ gen oder Kombinationen sind für geeignete Glasschmelztemperaturen und/oder Glaszusammensetzungen ebenfalls Gegenstand dieser Erfin­ dung.According to the present invention, the device parts in contact with the molten glass are made of
A) precious metals such as platinum, rhodium, palladium, gold, silver, ruthenium, iridium, osmium or their alloys or from combinations of these materials,
B) Non-noble metals such as nickel, iron and chromium or their alloys or combinations are also the subject of this invention for suitable glass melting temperatures and / or glass compositions.

Konsequenterweise werden diese Edel- und Nichtedelmetalle nicht in Vollmaterial Anwendung finden, sondern sind im Innern mit einem oder mehreren Kühlkanälen durchsetzt.Consequently, these precious and non-precious metals are not in Full material find application, but are inside with one or interspersed with several cooling channels.

Geeignete Stabilisierung im Innern der Rotationsgeräte sind in Form von Stangen, Bändern, Blechen, Waben oder in sonstiger Querschnittsform vorgesehen. Weiteren geeigneten stabilisierungstechnischen Möglichkei­ ten sind keine Grenzen gesetzt.Suitable stabilization inside the rotary devices are in the form of Bars, strips, sheets, honeycombs or in any other cross-sectional shape intended. Other suitable stabilization options There are no limits.

Durch die Ausbildung der Edel- und/oder Nichtedelmetallgeräte gemäß der Erfindung sind die Achsen der Rotationsbehälter und/oder der Flügel, Paddel, Fahnen mit Wasser-, Luft- und/oder Gaskühlkanälen versehen, was die Stabilisieren erhöht und Edelmetallkosten erheblich senkt. Auf den erwähnten Nachteil eines Vakuums kann in diesem Fall verzich­ tet werden.By training the precious and / or non-precious metal devices according to the axes of the rotary container and / or the wing of the invention, Provide paddles, flags with water, air and / or gas cooling channels, which increases stabilization and significantly reduces precious metal costs. In this case, the mentioned disadvantage of a vacuum can be dispensed with be tested.
