1. Selelekela :
UHP graphite electrodee sebelisoa bakeng sa ho nchafatsa tšepe indastering ea sebōpi sa motlakase sa arc.Karolo ea eona e ka sehloohong ke coke ea nale ea boleng bo holimo, e entsoeng ka petroleum kapa sekontiri sa mashala.Electrode ea graphite e entsoe ka sebōpeho sa cylindrical 'me sebaka se nang le khoele se etsoa ka lehlakoreng le leng le le leng.Ka tsela ena, electrode ea graphite e ka bokelloa ka har'a kholomo ea electrode ho sebelisa sehokelo sa electrode.
E le ho fihlela litlhoko tsa ts'ebetso e phahameng ea mosebetsi le litšenyehelo tse tlase kaofela, sebōpi se seholo sa "ultra-high power arc" se ntse se tsebahala haholoanyane.Ka hona, li-electrode tsa graphite tsa UHP tse bophara ba limilimithara tse fetang 500 li tla busa 'marakeng

(1) Matla a kamehla a graphite electrode
E lumelloa ho sebelisa electrode ea graphite e nang le boima ba hona joale bo ka tlaase ho 17a / cm2, e sebelisoang haholo ka libopi tse tloaelehileng tsa motlakase bakeng sa ho etsa tšepe, ho qhibiliha ha silicon, ho qhibilihisa phosphorus e mosehla, joalo-joalo.
(2) Eleketrode ea graphite e thibelang oxidation
Electrode ea graphite e koahetsoeng ka lera la tšireletso ea antioxidant (graphite electrode antioxidant).Theha lesela le sireletsang le ka tsamaisang motlakase le ho hanela oxidation ea mocheso o phahameng, ho fokotsa tšebeliso ea li-electrode nakong ea ho etsa tšepe (19% ~ 50%), ho lelefatsa bophelo ba ts'ebeletso ea elektrode (22% ~ 60%), le ho fokotsa tšebeliso ea matla a motlakase. ea electrode.Ho tuma le ho sebelisoa ha theknoloji ena ho ka tlisa liphello tse joalo tsa moruo le tsa sechaba:
① Ts'ebeliso ea yuniti ea electrode ea graphite e tlase, 'me litšenyehelo tsa tlhahiso li fokotsehile ho isa bohōleng bo itseng.Mohlala, setsing sa ho etsa litšepe, se ipapisitseng le ts'ebeliso ea li-electrode tsa graphite tse 35pcs ka beke le libopi tse 165 tsa ho hloekisa seboping sa mantlha sa LF ntle le ho koaloa ho pholletsa le selemo, li-electrode tse 373pcs tsa graphite li ka bolokeha selemo se seng le se seng ka mor'a hore theknoloji ea graphite electrode oxidation resistance e be teng. amohetsoe
(153 tons) electrode, e baloang ho 3000USD ka thane e le 'ngoe ea li-electrode tse phahameng ka ho fetisisa ka selemo, USD 459,000 e ka bolokeha.
② Electrode ea graphite e sebelisa matla a fokolang, e boloka tšebeliso ea matla a ho etsa tšepe, e boloka litšenyehelo tsa tlhahiso le ho boloka matla!
③ Hobane electrode ea graphite e fetoloa ka makhetlo a fokolang, palo ea basebetsi le kotsi ea basebetsi e fokotsehile, 'me katleho ea tlhahiso ea ntlafatsoa.
④ Graphite electrode ke sehlahisoa se tlase se sebelisoang haholo le tšilafalo e tlase.Kajeno, ha ho buelloa paballo ea matla, phokotso ea mosi le ho sireletsa tikoloho, e na le bohlokoa bo boholo sechabeng.
Theknoloji ena e ntse e le sethaleng sa lipatlisiso le nts'etsopele Chaena, 'me bahlahisi ba bang ba malapeng le bona ba se ba qalile ho e hlahisa.E 'nile ea sebelisoa haholo Japane le linaheng tse ling tse tsoetseng pele.Hona joale, ho boetse ho na le lik'hamphani tse sebetsanang le ho kenya thepa ena e sireletsang anti-oxidation Chaena.
(3) Elektrode e phahameng ea graphite.Electrode ea graphite e nang le boima ba hona joale ba 18 ~ 25A / cm2 e lumelloa ho sebelisoa, e sebelisoang haholo-holo sebōping sa motlakase sa motlakase se matla haholo bakeng sa ho etsa tšepe.
(4)Ultra e phahameng ea matla a graphite electrode.Li-electrode tsa UHP Graphite tse nang le letsoalo la hajoale ho feta 25A / cm2 li lumelloa.E sebelisoa haholo-holo bakeng sa sebōpi sa arc sa motlakase sa matla a phahameng a phahameng.
