Abstract
Düsenwanne aus einer Platinlegierung zur Herstellung von Glasfasern, die zwecks Minimierung von Edelmetallverlusten auf der der Gasseite zugewandten Außenseite mit einer keramischen Schutzschicht bedeckt ist, dadurch gekennzeichnet, dass die keramische Schutzschicht mittels einer Physikalischen Gasphasenabscheidung (physical vapour deposition / PVD-Verfahren) aufgebracht ist und aus Zirkoniumoxid-Yttriumoxid besteht.Nozzle trough made of a platinum alloy for the production of glass fibers, which is covered with a ceramic protective layer on the outside facing the gas side in order to minimize precious metal losses, characterized in that the ceramic protective layer by means of physical vapor deposition (PVD method) is applied and zirconia yttria.
Description
Die Erfindung betrifft die besondere Ausgestaltung einer Düsenwanne aus Platin und Platinlegierungen, wie sie zur Herstellung von Glasfasern üblich ist, um die Verdampfungsverluste an diesen Edelmetallen im Einsatz der Düsenwanne bei den erforderlichen hohen Betriebstemperaturen zu minimieren. The invention relates to the particular embodiment of a nozzle pan made of platinum and platinum alloys, as is customary for the production of glass fibers in order to minimize the evaporation losses of these precious metals in the use of the nozzle pan at the required high operating temperatures.
In der Glasindustrie werden bekanntermaßen wegen der erforderlichen Betriebstemperaturen von 1200°C bis 1600°C und wegen der oxidierenden Atmosphäre Geräte, insbesondere auch Düsenwannen, vornehmlich aus speziellen Platin-Rhodium-Legierungen verwendet, die wegen ihrer hohen thermischen und chemischen Stabilität den Anforderungen unter Produktionsbedingungen nachweislich am besten gerecht werden. Beim Einsatz von Düsenwannen aus diesen Platinlegierungen treten aber trotzdem nicht unerhebliche Edelmetallverluste auf durch Oxidation der Edelmetalle auf der Gasseite der Düsenwanne. Die Verdampfung der Oxide führt damit im Produktionsprozess zu Verlusten an wertvollem und teurem Edelmetall und erfordert mit hohem finanziellem Aufwand eine permanente Ergänzung dieser Verluste beim Recycling verbrauchter zwecks Herstellung neuer Düsenwannen. In the glass industry are known because of the required operating temperatures of 1200 ° C to 1600 ° C and because of the oxidizing atmosphere equipment, especially nozzle trays, mainly made of special platinum-rhodium alloys used, because of their high thermal and chemical stability requirements under production conditions demonstrably best. When using nozzle trays made of these platinum alloys, however, not inconsiderable precious metal losses occur due to oxidation of the noble metals on the gas side of the nozzle trough. The evaporation of the oxides thus leads to losses in the production process to valuable and expensive precious metal and requires a high financial outlay to permanently supplement these losses when recycling spent to make new nozzle trays.
Es wurde deshalb bereits vorgeschlagen, diese Verdampfungs-Verlustrate durch Maßnahmen zum Schutz der Seite der Oberfläche der Düsenwanne, die der Gasseite zugewandt ist, zu reduzieren. In dem Patent
Als Außenverkleidung wird eine Schicht aus den feuerfesten Materialen Magnesiumoxid, Zirkoniumoxid, Aluminiumoxid, Titanoxid, Chromoxid, Aluminid, Silicid, Beryllid, Borid oder aus deren Kombination empfohlen. As outer lining a layer of the refractory materials magnesium oxide, zirconium oxide, aluminum oxide, titanium oxide, chromium oxide, aluminide, silicide, beryllide, boride or their combination is recommended.
Das dazu vorgeschlagene Verfahren besteht darin, dass man die der Gasseite zugewandte, äußere Oberfläche der Düsenwanne einschließlich der für das Ziehen der Glasfäden vorgesehenen Düsen zunächst aufrauht, anschließend zur Herstellung des hochdichten Überzuges mit feuerfestem Material durch die Technologie des Flammspritzens beschichtet und abschließend die Öffnungskanten der röhrenförmigen Düsen glättet. Die der Stabilisierung der Düsenwanne dienenden Seitenwände und der Boden der Düsenwanne werden getrennt voneinander flammgespritzt und erst dann miteinander verschweißt. Es hat sich ein Nachteil dieser durch Flammspritzen beschichteten Düsenwanne herausgestellt. Im Dauerbetrieb der Düsenwanne lassen sich bekanntlich trotz der angeordneten Traversen, die der mechanischen Stabilisierung der Wannenform dienen, leichte Verwerfungen und Senkungen des Wannenbodens nicht verhindern. Dadurch kommt es zur Ausbildung von Rissen in der keramischen Außenverkleidung, wodurch der Zutritt von Sauerstoff an das Platinmaterial nicht mehr verhindert werden kann. Das heißt, die Platinverluste wurden durch die durch Flammspritzen auf den Düsenwannenkörper aufgebrachte keramische Außenverkleidung zwar verringert, aber die Dichtheit dieser Schutzschicht, die eine mehr oder weniger schuppige Struktur besitzt, ist gegen den Angriff von Sauerstoff unter Produktionsbedingungen nicht gewährleistet. The method proposed for this purpose comprises first roughening the outer side of the nozzle pan, including the nozzles provided for pulling the glass threads, facing the gas side, then coating it with refractory by the technology of flame spraying to produce the high-density coating, and finally sealing the opening edges of the tubular nozzle smoothes. The stabilization of the nozzle pan serving side walls and the bottom of the nozzle pan are flame-sprayed separately from each other and only then welded together. It has turned out to be a disadvantage of this flame-spray coated nozzle trough. In continuous operation of the nozzle pan can be known despite the arranged trusses, which serve the mechanical stabilization of the tub shape, light faults and subsidence of the tub bottom not prevent. This leads to the formation of cracks in the ceramic outer lining, whereby the access of oxygen to the platinum material can no longer be prevented. That is, the platinum losses were indeed reduced by the applied by flame spraying on the nozzle pan body ceramic outer lining, but the tightness of this protective layer, which has a more or less flaky structure is not guaranteed against the attack of oxygen under production conditions.
Gemäß Patent
In
Aufgabe der Erfindung ist es, eine beschichtete Düsenwanne für die Herstellung von Glasfasern zu entwickeln, die aus einem für die üblichen hohen Arbeitstemperaturen bekannten Platinwerkstoff besteht und deren der Gasseite zugewandte Außenfläche mit einer dichten, keramischen Verkleidung beschichtet ist, die unter mechanischer Beanspruchung und unter hoher thermischer Belastung eine Verflüchtigung von Platinoxid verhindert. The object of the invention is to develop a coated nozzle pan for the production of glass fibers, which consists of a known for the usual high working temperatures platinum material and the gas side facing the outer surface is coated with a dense, ceramic cladding, the under mechanical stress and high Thermal stress prevents volatilization of platinum oxide.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass auf den der Gasphase ausgesetzten Bereich der Düsenwanne mittels einer Physikalischen Gasphasenabscheidung (physical vapour deposition – PVD), vorzugsweise mittels Elektronenstrahlverdampfen (electron beam evaporation) eine keramische Schutzschicht, die aus Zirkoniumoxid-Yttriumoxid besteht, in einer Schichtstärke von 1,0 bis 100 µm, vorzugsweise 10 bis 40 µm aufgebracht ist. According to the invention this object is achieved in that on the exposed to the gas phase region of the nozzle well by means of a physical vapor deposition (PVD), preferably by electron beam evaporation (electron beam evaporation) a ceramic protective layer consisting of zirconia yttria, in a layer thickness from 1.0 to 100 microns, preferably 10 to 40 microns is applied.
Die Schutzschicht besteht aus 80 bis 95 Masse-% Zirkoniumoxid und 5 bis 20 Masse-% Yttriumoxid. Überraschenderweise hat sich gezeigt, dass die erfindungsgemäße, durch PVD-Verfahren aufgetragene Schutzschicht eine sehr dichte, pelzartige Schichtstruktur aufweist, die auch bei starker Biegebelastung unter extremen thermischen Bedingungen mechanisch flexibel bleibt und einen haftfesten, dichten und damit dauerhaften Schutz des Platinmaterials der Düsenwanne gegen die aggressive oxidische Gasatmosphäre im Langzeitbetrieb gewährleistet und ein Abdampfen von Platinoxid verhindert. The protective layer consists of 80 to 95% by mass of zirconium oxide and 5 to 20% by mass of yttrium oxide. Surprisingly, it has been found that the protective layer applied by PVD process according to the invention has a very dense, fur-like layer structure which remains mechanically flexible even under heavy bending conditions under extreme thermal conditions and an adherent, dense and thus permanent protection of the platinum material of the nozzle trough against the ensures aggressive oxidic gas atmosphere in long-term operation and prevents evaporation of platinum oxide.
