UHP graphite electrode 650*2700mm
Ama-electrode e-graphite anamandla amakhulu afanelekela iziko likagesi ezinkulu ze-ultra-high-power, amathani angaphezu kuka-50 weziko likagesi ze-arc;umjikelezo wokuncibilikisa umfishane ngo-25% kunezithando ze-arc zikagesi ezivamile, unciphisa ukusetshenziswa kwamandla futhi uthuthukise ukusebenza kahle kokukhiqiza.I-electrode ye-Dan charcoal graphite electrode elandelayo izokwethula ukusetshenziswa kwe-electrode ye-graphite yamandla aphezulu kakhulu kanye nenqubo ye-electrode ye-graphite yamandla asezingeni eliphezulu futhi aphezulu.
I-electrode ye-graphite yamandla aphezulu kakhulu yenziwe nge-coke yenaliti yekhwalithi ephezulu, ekhiqizwa ngezinqubo ezingaphezu kweshumi nambili ezifana nokubala, ukukhishwa, ukukhulelwa, i-graphitization kanye nemishini.eside.Ivumela ukuminyana kwamanje ukuthi kube kukhulu kuno-25A/cm2, futhi isetshenziselwa ikakhulukazi ukuncibilikisa insimbi ecolekileyo nensimbi ekhethekile.
Ezinsukwini zokuqala, ama-electrode asekhaya e-ultra-high-power graphite ayethembele kakhulu ekuthengisweni kwamanye amazwe.Ngenxa yobuxhakaxhaka bobuchwepheshe bamazwe athuthukile eYurophu, eMelika naseJapan, ukukhiqizwa kwasekhaya bekukude kakhulu nokuhlangabezana nesidingo.Ngokuthuthukiswa kwemboni yensimbi, ama-electrode amaningi e-graphite
abakhiqizi batshale imali eningi nobuchwepheshe ku-R&D kanye nokukhiqizwa kwama-electrode e-graphite anamandla aphezulu.Ama-electrode e-Dan charcoal graphite azuze ama-electrode e-graphite wamandla aphezulu kakhulu angu-UHP700mm ukuze anikeze izigayo zensimbi zangaphandle ngezivivinyo ezifanelekayo nokukhiqizwa ngobuningi.I-UHP800mm isithuthukiswe ngokugcwele.Ama-electrode amagraphite anamandla aphezulu kakhulu.
Ukwenza insimbi yesithando somlilo ngumsebenzisi omkhulu wama-graphite electrode.ukukhiqizwa kwensimbi yesithando somlilo kagesi ezweni lami kubiza cishe u-18% wokukhiqizwa kwensimbi engahluziwe, kanye nama-electrode e-graphite okwenza insimbi athatha u-70% kuya ku-80% wengqikithi yokusetshenziswa kwama-electrode e-graphite.Ukwenza insimbi yesithando somlilo ukusebenzisa ama-electrode egraphite ukwethula okwamanje esithandweni, nokusebenzisa umthombo wokushisa onezinga lokushisa eliphezulu okhiqizwe i-arc phakathi kwesiphetho se-electrode kanye nokushaja ukuze kuncibilike.
Isithando somlilo esishisayo esingaphansi kwamanzi sisetshenziselwa ikakhulukazi ukukhiqizwa kwe-silicon yezimboni kanye ne-phosphorus ephuzi, njll. Ibonakala ngokuthi ingxenye engezansi ye-electrode conductive ingcwatshwe ekushajeni, kwakhiwa i-arc kungqimba lokushaja, kanye nokushisa. amandla akhishwa ukushaja ukumelana asetshenziswa ukushisisa ukushaja.Izithando ze-arc ezingaphansi kwamanzi ezinokuminyana okuphezulu zidinga ukusebenzisa ama-electrode e-graphite.Isibonelo, cishe i-100kg yama-electrode e-graphite asetshenziselwa ukukhiqiza i-1t ye-silicon, futhi cishe u-40kg wama-electrode e-graphite asetshenziselwa ukukhiqiza i-1t ye-phosphorus ephuzi.
Izithando ze-Graphitization zokukhiqizwa kwemikhiqizo ye-graphite, izithando zomlilo ezincibilikisa ingilazi encibilikayo, kanye neziko likagesi lokukhiqiza i-silicon carbide zonke iziko lokumelana.Izinto ezisesithandweni zombili ziyizinto zokushisisa nezinto okumele zishiswe.Ngokuvamile, ama-electrode e-graphite conductive afakwe ekugcineni kwesithando somlilo.Odongeni lwekhanda lesithando somlilo ezansi, ama-electrode egraphite asetshenziswa lapha ayanqanyulwa.
Izikhala zama-electrode e-graphite nazo zisetshenziselwa ukucubungula imikhiqizo ehlukahlukene ye-graphite efana ne-crucibles, isikhunta, izikebhe nezinto zokufudumeza.Ngokwesibonelo, embonini yengilazi ye-quartz, amathani angu-10 ezikhala ze-graphite electrode ziyadingeka kulelo nalelo toni elingu-1 lepayipi lokuhlanganisa likagesi elikhiqizwayo;I-100 kg yezikhala ze-graphite electrode ziyadingeka kuzo zonke ithani elingu-1 lezitini ze-quartz ezikhiqizwayo.
Ngokwamandla esithando somlilo se-arc kagesi, ihlukaniswe yaba isithando somlilo esivamile sikagesi se-arc (ngaphansi kuka-400kV.A/t), isithando somlilo esinamandla amakhulu kagesi (400kV.A/t~700kV.A/t), amandla aphezulu kakhulu isithando somlilo se-arc sikagesi (ngaphezu kuka-700kV.A/t) .Ngokusho kwesimiso sokuthi yimaphi amandla omlilo we-arc kagesi afaniswa ne-electrode ye-graphite yamandla, i-electrode ye-graphite yamandla aphezulu aphezulu isetshenziswa nge-ultra-high power electric arc furnace.

Inqubo yokukhiqiza yama-electrode e-graphite ikakhulukazi yakhiwe ngokubala kwezinto ezingavuthiwe, i-extrusion yesithako, ukucwiliswa nokuwugazinga, i-graphitization kanye nokucubungula ngomshini.Kukhona umehluko othile emjikelezweni wokukhiqiza kanye nezinto zokusetshenziswa zama-electrode anamandla ahlukene.
