Description
Anordning ved elektroder i elektriske smelteovner. Device at electrodes in electric melting furnaces.
Elektrodene i elektriske smelteovner The electrodes in electric melting furnaces
er som bekjent bevegelig opphengt i så-kalte elektrodespill slik at deres vertikale stilling kan reguleres i samsvar med elektrodeforbruket og de elektriske forhold i ovnen i øyeblikket. Ved moderne ovner benytter man nu som regel hydrauliske elektrodespill hvor trykkmediet ugjøres av olje. Det anvendes vanligvis to hydrauliske sylindre pr. elektrode, og disse er forbundet med et åk eller lignende som bærer elektrodeholderen og dermed elektroden. Sylindrene kan være opphengt i taket over åket eller stå på gulvet under åket, og man taler da om hengende, respektive stående hydrauliske elektrodespill. Oljen pumpes fra en pumpestasjon inn i sylindrene, og heisehastigheten er bestemt av pumpe-kapasiteten. Senkehastigheten reguleres av en kontrollventil i returledningen til pumpestasjonen. are, as is known, movably suspended in so-called electrode winches so that their vertical position can be regulated in accordance with the electrode consumption and the electrical conditions in the furnace at the moment. Modern furnaces now usually use hydraulic electrode sets where the pressure medium is made up of oil. Two hydraulic cylinders are usually used per electrode, and these are connected by a yoke or similar that carries the electrode holder and thus the electrode. The cylinders can be suspended from the ceiling above the yoke or stand on the floor below the yoke, and one then speaks of hanging or standing hydraulic electrode winches. The oil is pumped from a pumping station into the cylinders, and the lifting speed is determined by the pump capacity. The lowering speed is regulated by a control valve in the return line to the pump station.
Da elektrodestillingen som nevnt skal As the electrode position as mentioned should
reguleres både i samsvar med elektrodeforbruket og de elektriske forhold i ovnen i øyeblikket, kan man over enkelte perioder få meget hyppige reguleringer, og dette sliter på reguleringsutstyret slik at dets levetid blir vesentlig forkortet. is regulated both in accordance with the electrode consumption and the electrical conditions in the furnace at the moment, one can get very frequent regulation over certain periods, and this wears out the regulation equipment so that its lifetime is significantly shortened.
Det er kjent at den senkning av elektroden som er en følge av elektrodeforbruket kan foregå kontinuerlig ved at elektroden skyves kontinuerlig nedover gjennom elektrodeholderen under påvirkning av trykkorganer. Ved anordningen ifølge oppfinnelsen muliggjøres kontinuerlig senkning av elektroden uten påvirkning av slike ytre trykkorganer. Dette skjer ved at man anordner en by-pass over reguleringsventilen for elektrodespillet og anbringer en annen reguleringsventil, for eksempel en nåleventil, i denne by-pass, hvorpå sist-nevnte ventil innstilles slik at en konstant mengde olje stadig siver ut av oljesylind-rene og gjennom bypass'en, idet mengden olje tilpasses slik at man får en kontinuerlig senkning av elektroden som svarer til elektrodeforbruket i ovnen. Herved redu-seres antallet koblinger av regulatoren, og de elektriske forhold i ovnen blir mer sta-bile. It is known that the lowering of the electrode which is a consequence of electrode consumption can take place continuously by the electrode being continuously pushed downwards through the electrode holder under the influence of pressure means. With the device according to the invention, continuous lowering of the electrode is made possible without the influence of such external pressure means. This happens by arranging a by-pass over the control valve for the electrode play and placing another control valve, for example a needle valve, in this by-pass, after which the last-mentioned valve is adjusted so that a constant amount of oil constantly seeps out of the oil cylinders and through the bypass, with the amount of oil being adapted so that a continuous lowering of the electrode is obtained which corresponds to the electrode consumption in the oven. This reduces the number of connections of the regulator, and the electrical conditions in the oven become more stable.
Et eksempel på en utførelse av oppfinnelsen er skjematisk illustrert på ved-lagte figur, hvor 1 betegner elektroden og 2 elektrodeholderen, som er opphengt i et An example of an embodiment of the invention is schematically illustrated in the attached figure, where 1 denotes the electrode and 2 the electrode holder, which is suspended in a
åk eller lignende 3 ved hjelp av stag eller lenker 4. Anordning for strømtilførsel til elektroden er ikke vist på tegningen. Åket yoke or similar 3 using stays or links 4. Device for power supply to the electrode is not shown in the drawing. The ride
3 er forbundet med sylindrene 6, mens 3 is connected to the cylinders 6, while
stemplene 5 i sylindrene 6 er vist opplagret på et gulv 7. De kan selvsagt være opplagret på hvilken som helst hensiktsmes-sig måte. Sylindervolumet under stemplene 5 er som nevnt fylt med olje som føres til the pistons 5 in the cylinders 6 are shown stored on a floor 7. They can of course be stored in any suitable way. As mentioned, the cylinder volume below the pistons 5 is filled with oil which is fed to
og fra sylindrene gjennom ledningssyste-met 8. 9 indikerer pumpestasjonen for olje. and from the cylinders through the wiring system 8. 9 indicates the pumping station for oil.
10 er en enveis ventil som bare tillater 10 is a one-way valve that only allows
oljen å strømme i retning mot sylindrene gjennom rørene 11 og 8. Når elektroden skal senkes, strømmer olje fra oljesylind-rene 6 gjennom rørene 8 og 12 og gjennom senkningsventilen for elektrodespillet, som er skjematisk antydet med 13. 14 er den by-pass som ifølge oppfinnelsen er anordnet over reguleringsventilen 13 og utstyrt med en regulerbar ventil 15, for eksempel en nåleventil, som innstilles slik the oil to flow in the direction of the cylinders through the pipes 11 and 8. When the electrode is to be lowered, oil flows from the oil cylinders 6 through the pipes 8 and 12 and through the lowering valve for the electrode winch, which is schematically indicated by 13. 14 is the by-pass which according to the invention is arranged above the control valve 13 and equipped with an adjustable valve 15, for example a needle valve, which is set as follows
at det alltid vil sive en sådan mengde olje gjennom by-pass'en at elektrodeforbruket i ovnen kompenseres ved tilsvarende senkning av elektroden. that such an amount of oil will always seep through the by-pass that the electrode consumption in the furnace is compensated by a corresponding lowering of the electrode.
Oppfinnelsen er ovenfor beskrevet i for-bindelse med hyldraulisk elektrodespill hvor det anvendes olje som trykkmedium. Den kan imidlertid selvsagt anvendes ved et hvilket som helst hydraulisk eller pneu-matisk elektrodespill hvor det anvendes væske og/eller gass som trykkmedium. The invention is described above in connection with hydraulic electrode play where oil is used as pressure medium. However, it can of course be used with any hydraulic or pneumatic electrode winch where liquid and/or gas is used as pressure medium.
