Elektrisk glassovn. Electric glass furnace.
Det norske hovedpatent 104 429 beskriv ver en elektrisk glassovn omfattende en raffineringsinnretning anordnet i det indre av ovnskaret på det varmeste sted i dette, idet innretningen omfatter midler for i løpet av den kontinuerlige uthelling å ta ut en del av det smeltede glass i dette om-råde og derved fjerne denne fra de sterke bevegelser som skyldes konvekssjonsstrøm-mene som hersker i ovnskammeret, midler for å underkaste denne del en hurtig tem-peraturstigning for å minske dens viskosi-tet og for å øke størrelsen av blærene som derved atskilles fra det fine glass, midler for uttømming av det således oppnådde fine glass ut av ovnen etter hvert som produk-sjonen skrider frem og midler for tilbake-føring til badet inne i ovnen av de således utskilte blærer. The Norwegian main patent 104 429 describes an electric glass furnace comprising a refining device arranged in the interior of the furnace vessel at the hottest place therein, the device comprising means for taking out part of the molten glass in this environment during the continuous pouring. advise and thereby remove it from the strong movements caused by the convection currents that prevail in the furnace chamber, means to subject this part to a rapid temperature rise in order to reduce its viscosity and to increase the size of the bubbles that are thereby separated from the fine glass, means for emptying the thus obtained fine glass out of the furnace as production progresses and means for returning the bubbles thus separated to the bath inside the furnace.
Foreliggende oppfinnelse angår modi-fikasjoner og forbedringer av denne ovn. The present invention relates to modifications and improvements of this oven.
Spesielt ved en utførelsesform av ovnen ifølge det ovennevnte patent omfatter raffineringsinnretningen to horisontale skiver med omtrent plane eller koniske overflater som i det minste ved sine kanter ligger nær hinannen, idet mellomrom-met mellom skivene står i forbindelse med en eller flere utløpsåpninger for blærene og med en uttaksinnretning for det raffinerte glass. Utløpsåpningen for blærene står i forbindelse med ovnens indre og ut-taksåpningen for det raffinerte glass står i forbindelse med ovnens ytre. Den nevnte anordning som gjør det mulig å utsette den uttatte glassporsjon for en hurtig tempe-raturstigning, omfatter en elektrisk strøm-kilde hvis klemmer er henholdsvis forbundet med de to sider i innretningen. In particular, in an embodiment of the furnace according to the above-mentioned patent, the refining device comprises two horizontal disks with roughly flat or conical surfaces which at least at their edges are close to each other, the space between the disks being in connection with one or more outlet openings for the bladders and with an outlet device for the refined glass. The outlet opening for the bladders is in connection with the interior of the furnace and the outlet opening for the refined glass is in connection with the exterior of the furnace. The aforementioned device, which makes it possible to expose the removed glass portion to a rapid temperature rise, comprises an electric current source whose terminals are respectively connected to the two sides of the device.
Ovnen ifølge foreliggende oppfinnelse avviker fra denne utførelsesform ved modi-fikasjoner som er fremkommet ved under-søkelser og eksperimenter som tar sikte på ytterligere forbedring av ovnens utbytte og for å forenkle dens konstruksjon. The furnace according to the present invention deviates from this embodiment by modifications that have emerged from research and experiments aimed at further improving the yield of the furnace and to simplify its construction.
En første serie forsøk har vist at det var mulig å undertrykke den strøm som sirkulerer mellom skivene, ved å variere spenningen over klemmene på sideelektro-dene og ved at de bringes nærmere den sentrale elektrode, med andre ord ved drift av ovnen med samme effekt, men med en lavere spenning og følgelig med en større strømstyrke, hvilket har den virk-ning at ovnens sentrale del opphetes indi-rekte og at glasset derved fåes i en tilstrek-kelig flytende tilstand til at en utmerket atskillelse av blærene kan foretas. A first series of experiments has shown that it was possible to suppress the current circulating between the disks, by varying the voltage across the clamps on the side electrodes and by bringing them closer to the central electrode, in other words by operating the furnace with the same power, but with a lower voltage and consequently with a greater amperage, which has the effect that the central part of the furnace is heated indirectly and that the glass is thereby brought into a sufficiently liquid state to allow an excellent separation of the blisters.
Det er således mulig å unnvære de to strømmatningsstenger forbundet med henholdsvis den øvre og den nedre skive. Den øvre skive kan ganske enkelt anbringes på den nedre skive ved at der mellom dem anbringes stykker av molybden. It is thus possible to dispense with the two power supply rods connected to the upper and lower discs respectively. The upper disk can simply be placed on the lower disk by placing pieces of molybdenum between them.
Det har på den annen side vist seg at det er mulig å trekke i det minste delvis en del av glasset ut av de konveksjons-strømmer som hersker i ovnens smeltesone ved å benytte en enkelt skive med stor diameter. Glasset som er avgrenset i det kanallignende rom mellom skivens kanter og elektrodene, oppvarmes, hvilket letter blærenes oppstigning. Glasset tas alltid ut i skivens senter og det oppstår derved en blærefri sone forutsatt at uttaksmengden av glass omhyggelig holdes under en be- On the other hand, it has been shown that it is possible to pull at least part of the glass out of the convection currents that prevail in the melting zone of the furnace by using a single disk with a large diameter. The glass, which is confined in the channel-like space between the disc's edges and the electrodes, is heated, which facilitates the ascent of the bubbles. The glass is always taken out in the center of the disc and a blister-free zone is thereby created, provided that the amount of glass removed is carefully kept under a

Endelig har det vist seg at dette uttak Finally, it has been shown that this outlet
