Description

lfl 10 15 25 30 35 7902653-0, 2 licidrörets 12 insida är i den yttre änden avtätad medelst en tätningsmassa 19 av lämpligt slag. l fl 10 15 25 30 35 7902653-0, 2 the inside of the liquid pipe 12 is sealed at the outer end by means of a sealing compound 19 of a suitable type.

Såsom visas på ritningen är lämpligen molybdenstavens ll yttre ändyta och molybdendisilicidrörets inre ändyta koniskt slipade så att kontaktytorna skall bli så stora som möjligt och kontaktmotståndet så lågt som möjligt.As shown in the drawing, suitably the outer end surface of the molybdenum rod 11 and the inner end surface of the molybdenum disilicid tube are conically ground so that the contact surfaces are as large as possible and the contact resistance as low as possible.

I drift är elektroden införd genom den med 20 generellt betecknade och endast schematiskt antydda feederväggen genom en öppning i denna, så att någon del av glassmältan tränger något in i feederväggen, såsom antyds vid 21 i figuren.In operation, the electrode is inserted through the feeder wall generally designated and only schematically indicated by an opening therein, so that some part of the glass melt penetrates slightly into the feeder wall, as indicated at 21 in the figure.

Modifikationer och detaljändringar kan företas inom ramen för uppfinningstanken, exempelvis i det att man till kompensation för de skilda värmeutvidgningskoefficienterna hos molybden och molybdendisilicid icke utnyttjar en skruv- ' del 17 av stål utan av något annat material med ännu större värmeutvidningskoefficient.Modifications and detailed changes can be made within the scope of the inventive idea, for example in that, to compensate for the different coefficients of thermal expansion of molybdenum and molybdenum disilicide, a screw part 17 of steel is not used but of another material with an even greater coefficient of thermal expansion.

Claims (1)

1. 0 15 20 25 30 35 7902653-0 Patentkrav. Elektrod för uppvärmning av t.ex. glasmassa genom di- rekt strömgenomgàng genom glaset och bestående av en t.ex. stavformig kropp, som förs genom väggen till en feeder e.dyl. och ansluts till en strömledare vid sin yttre ände medan den inre änden skjuter in i glasmassan, kännetecknad av den kombinationen att den i glasmassan inskjutande, inre elektroddelen (ll) består av molybden medan den för höga temperaturer i luft utsatta, yttre elektroddelen (12) till väsentlig del består av molybdendisilicid, MoSi2, att den yttre elektroddelen består av ett rör (12), som hålls i kontakt med den inre elektroddelen i form av en molybdenstav (ll), ände mot ände, medelst en röret genom- gående spännskruv (13), som är inskruvad i molybdenstaven (11) och är försedd med ett fjäderpaket (15) och en spänn- mutter på sin från röret (12) utskjutande ände, och att den del av spännskruven, som är belägen i den inre elektroddelen, består av molybden och resten av stål.1. 0 15 20 25 30 35 7902653-0 Patent claims. Electrode for heating e.g. glass mass by direct current passage through the glass and consisting of a e.g. rod-shaped body, which is passed through the wall to a feeder or the like. and connected to a current conductor at its outer end while the inner end projects into the glass mass, characterized by the combination that the inner electrode part (11) projecting into the glass mass consists of molybdenum while the outer electrode part (12) exposed to high temperatures in air essentially consists of molybdenum disilicide, MoSi2, that the outer electrode part consists of a tube (12), which is kept in contact with the inner electrode part in the form of a molybdenum rod (II), end to end, by means of a clamping screw through the tube ( 13), which is screwed into the molybdenum rod (11) and is provided with a spring package (15) and a clamping nut on its end projecting from the tube (12), and that the part of the clamping screw which is located in the inner electrode part, consists of molybdenum and the rest of steel.
