Ukusetshenziswa kanye nezakhiwo zama-graphite electrode:

1. Isetshenziswa esithandweni sokwenza insimbi ye-arc kagesi

Ama-electrode e-graphite asetshenziswa kakhulu ekwenzeni insimbi yesithando somlilo.Ukwenza insimbi yesithando somlilo ukusebenzisa ama-electrode egraphite ukwethula amanje esithandweni.I-current enamandla idlula igesi engxenyeni engezansi yama-electrode ukuze ikhiqize ukukhishwa kwe-arc, futhi ukushisa okukhiqizwa yi-arc kusetshenziselwa ukuncibilikisa.Ngokusho komthamo wesithando somlilo, ama-electrode e-graphite anama-diameter ahlukene asetshenziswa.Ukuze wenze ama-electrode asetshenziswe ngokuqhubekayo, ama-electrode axhunywe ngamajoyini anentambo ye-electrode.Ama-electrode e-graphite we-steelmaking account cishe amaphesenti angama-70-80 yenani eliphelele lama-electrode egraphite.

2. Isetshenziswa esithandweni sikagesi esishisayo esingaphansi kwamanzi

I-graphite electrode esithandweni somlilo esishisayo sikagesi sisetshenziselwa ikakhulukazi ukukhiqiza i-ferroalloy, i-silicon ehlanzekile, i-phosphorus ephuzi, i-matte ne-calcium carbide, njll. Ibonakala ngokuthi ingxenye engezansi ye-electrode conductive ingcwatshwe ngokushaja, ngakho-ke ngaphezu kokushisa. okukhiqizwa i-arc phakathi kwepuleti kagesi kanye nokushaja, Ukushisa kwamanje nakho kukhiqizwa ukumelana nokushaja lapho kudlula ukushaja.Ithani ngalinye le-silicon lidinga ukusebenzisa cishe u-150kg wama-electrode e-graphite, futhi ithani ngalinye le-phosphorus ephuzi lidinga ukusebenzisa cishe u-40kg wama-graphite electrode.

3. Isetshenziswa esithandweni sokumelana

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 okuqhuba afakwa odongeni lokushisa ekupheleni kweziko, ukuze ama-electrode conduction angashisi ngokuqhubekayo.

4. Okokucubungula

Inani elikhulu lezikhala ze-graphite electrode nazo zisetshenziselwa ukucubungula imikhiqizo ehlukahlukene efana nezikhisi, izikebhe ze-graphite, isikhunta esicindezelayo esishisayo kanye nezinto zokushisa ze-vacuum kagesi kagesi.Kumele kuqashelwe ukuthi kunezinhlobo ezintathu zezinto zokwenziwa kwezinto ze-graphite emazingeni okushisa aphezulu, okuhlanganisa ama-electrode e-graphite, isikhunta se-graphite kanye ne-graphite crucibles.I-graphite kulezi zinto ezintathu ijwayele ukuhlangana ne-oxidative combustion emazingeni okushisa aphezulu, okuholela kungqimba lwekhabhoni ebusweni bento.Ukwenyuka kwe-porosity kanye nesakhiwo esixekethile kuthinta impilo yesevisi.

Ama-electrode e-graphite enziwa ngokuyinhloko nge-petroleum coke ne-needle coke, kanti i-coal tar pitch isetshenziswa njenge-binder.Zenziwa ngokubala, ukuxubha, ukuxova, ukucindezela, ukugazinga, i-graphitization, nomshini.Bakhulula amandla kagesi ngendlela yama-arcs ezithandweni zikagesi ze-arc.Amakhondaktha okushisa nokuncibilikisa inkokhiso angahlukaniswa abe ama-electrode avamile wegraphite, amandla aphezulu e-graphite electrode kanye nama-electrode we-graphite wamandla aphezulu kakhulu ngokwezinkomba zawo zekhwalithi.
