Description
Predmetom vynálezu je klzná, vodou chladená upchávka horúcej elektrografitačnej elektrody, ktorá vytvára okolo chladnejšieho, mimo muriva pece vyčnievajúceho konca elektrody nepriepustnú, ohrievaniu zamedzujúcu protivzdušnú clonu, pričom umožňuje elektróde v smere osi pece voíne sa pohybovat.The object of the invention is a sliding, water-cooled plug of a hot electrographitic electrode which forms an impermeable heating-preventing air curtain around the colder, outside the furnace masonry projecting the electrode, allowing the electrode to move freely in the direction of the furnace axis.
Doterajšie prevedenie upchávok elektrografitačných elektrod vtakýchto peciach s priamym prechodom prúdu a teplotou v střede pece okolo 2500 °C, sa prevádza jednoduchým natočením azbestovej šňůry medzi murivo a elektrody na vonkajšej straně pece a ich ošamotovaním.The current design of plugs of electrographitic electrodes in these furnaces with a direct current passage and a temperature in the center of the furnace of about 2500 ° C is done by simply turning the asbestos cord between the masonry and the electrodes on the outside of the furnace and scraping them.
Spoločným nedostatkom týchto upchávok je nedostatočné utesnenie priestoru medzi murivom a elektrografitačnou elektrodou a to hlavně, aksa elektrodou občas pohybuje. Týmto sa potom umožňuje přístup kyslíkůzo vzduchu až k horúcej, nechladenej časti elektrografitačnej elektrody. Toto umožňuje jej ohrievanie v časti teplejšej, než 600 °C čo je hranica ohrievania uhlíka vzduchu. Po krátkom čase takto utěsněná horúca elektrografitačná elektroda obhorí a zlomí sa.A common drawback of these seals is the inadequate sealing of the space between the masonry and the electrographite electrode, especially if the electrode occasionally moves. In this way, oxygen oxygen is then allowed to reach the hot, uncooled portion of the electrographite electrode. This allows it to be heated in a part warmer than 600 ° C, which is the limit of heating the carbon carbon. After a short period of time, the sealed hot electrographite electrode burns and breaks.
Tieto nedostatky doteraz používaných jednoduchých upchávok odstraňuje klzná, vodou chladená upchávka horúcej elektrografitačnej elektrody, vytvárajúca nepriepustnú, ohrievaniu odolnú protivzdušnú clonu okolo horúcej elektrografitačnej elektrody. Jej podstata spočívá v tom, že na čelnej straně pece je do kruhu stočená azbestová šnúra, ktorá je přitlačená tesniacou přírubou, tvoriacou nepriedyšný celok s kovovou polotrubkou, vyplněnou azbestovým povrazcom pre volné pretekajúci prúd chladiacej vody.These drawbacks of previously used single plugs are overcome by a sliding, water-cooled plug of the hot electrode graphite, creating an impermeable, heat-resistant air curtain around the hot electrode graphite. It is based on the fact that on the front side of the furnace, an asbestos cord is twisted into a circle, which is pressed against a sealing flange forming a non-obstruction unit with a metal half-tube filled with an asbestos strand for a free flowing cooling water flow.
Příkladné prevedenie takejto klznej vodou chladenej upchávky horúcej elektrografitačnej elektrody je vidieť na pripojenom obrázku.An exemplary embodiment of such a sliding water-cooled seal of a hot electrographitic electrode is shown in the attached figure.
Horúca elektrografitačná elektroda 9 je uložená v murive elektrografitačnej pece 1, ako aj v ocelověj konštrukcii upchávky 2. Okolo horúcej elektrografitačnej elektrody 9 sú z vonkajšej strany pece vložené tesniace uhlíkové medzikružia 8, z čela pece utěsněné do kruhu stočenou azbestovou šňůrou 7 a tesniacou přírubou 6. Na tejto prírube je vzduchotěsně privarená kovová polotrubka 4, vyplněná azbestovým povrazcom 5, pomedzi ktorý preteká prúd chladiacej vody.The hot electrographitic electrode 9 is embedded in the masonry of the electrographitic furnace 1 as well as in the steel structure of the packing 2. Around the hot electrographitic electrode 9, a sealing carbon annulus 8 is inserted from outside the furnace, sealed from the furnace face by a twisted asbestos cord 7 and On this flange there is an airtightly welded metal half-pipe 4, filled with an asbestos strand 5, between which a flow of cooling water flows.
Funkcia takejto upchávky je nasledovná: Prúd chladiacej vody 3, přivedený do kovověj polotrubky preteká pomedzi azbestový povrazec 5 na horúcu elektrografitačnú elektrodu 9, čím z nej odvádza teplo. Zároveň tento prúd chladiacej vody 3 vytvára protivzdušnú clonu, spolu aj s azbestovou šňůrouThe function of such a seal is as follows: The flow of cooling water 3 supplied to the metal half-pipe flows between the asbestos strand 5 to the hot electro-graphite electrode 9, thereby dissipating heat therefrom. At the same time, this cooling water flow 3 forms an air curtain, together with the asbestos cord
19*595 a tesniacou přírubou 6. Zabráněním přístupu kyslíka na horúcu časť elektrografitačnej elektrody 9 je táto uchráněná před uhorievaním. Uhlíkové tesniace medzikružie 8 tvoria přitom klznú aj tesniacu časť upchávky a umožňujú přitom hladký občasný pohyb horúcej elektrografitačnej elektrody 9 v pozdížnej osi elektrografitačnej pece.19 * 595 and sealing flange 6. By preventing oxygen from accessing the hot portion of the electrographitic electrode 9, the electrode 9 is protected from burning. The carbon sealing ring 8 forms both the sliding and the sealing part of the stuffing box and allows the smooth occasional movement of the hot electrographite electrode 9 in the longitudinal axis of the electrographite furnace.
