Indlela yokuvimbela i-oxidation yama-electrode e-graphite ngesikhathi sokwenza insimbi.Ama-electrode e-graphite asetshenziswa ku-arc metallurgy njengezinto ezisetshenziswayo ezisetshenziswayo, futhi izindleko zabo zokusebenzisa zibalelwa ku-10-15% wezindleko zokwenza insimbi yesithando somlilo.

Eminyakeni yamuva, ukuze kuthuthukiswe ukukhiqizwa kwezithando zikagesi futhi kuncishiswe ukusetshenziswa kwamandla, izithando zikagesi zamukele ukusebenza komthwalo omkhulu, futhi ukusetshenziswa kwe-oxidation yezindawo zama-electrode kuvame ukukhuphuka, ngaleyo ndlela kukhulise ukusetshenziswa kwe-electrode kanye nezindleko zokuncibilikisa. wena oxidize electrode graphite

Ama-electrode e-graphite angavikelwa ngokumelene ne-oxidation ngokusebenzisa i-coating yokuzivikela ebusweni be-electrode.Nazi ezinye izindlela zokuvimbela i-oxidation yama-graphite electrode:

1. Okokuqala, indingilizi yemigodi engajulile yenziwa ngomshini ebusweni be-electrode yegraphite, inhloso ukwenza ungqimba lwe-cermet lunamathele ngokuqinile ebusweni be-graphite electrode, bese i-electrode yegraphite ishisiswe cishe ku-250 ℃ isithando sokushisa, bese kusetshenziswa isibhamu sensimbi se-spray ku-electrode.Phakamisa, fafaza ungqimba oluncane lwe-aluminium, fafaza olunye ungqimba lwe-cermet slurry kungqimba lwe-aluminium, bese usebenzisa i-carbon arc ukuze usike i-slurry, fafaza i-slurry ne-arc sinter, phinda izikhathi ezingu-2-3 ukwenza i-cermet. ukujiya okwanele.

I-resistivity ye-cermet ingu-0.07-0.1pm, ephansi kunaleyo ye-graphite electrode.Ku-900 ℃ ngamahora angu-50, igesi ayinamanzi futhi izinga lokushisa lokubola liyi-1750-1800 ℃.Ukwakheka kwento yokumboza akunawo umthelela kunsimbi encibilikisiwe.Ukwandisa izinto zokusetshenziswa, ugesi kanye nomsebenzi osetshenziswa embotsheni ye-anti-oxidation kuzonyusa izindleko zama-electrode egraphite ngo-10%, kepha ukusetshenziswa kweyunithi yama-graphite electrode ngethani lensimbi yomlilo kagesi kungancishiswa ngo-20-30% (umphumela ukusetshenziswa ezithandweni zikagesi ezijwayelekile).Njengoba ukugqoka kuyinto ephukayo, i-cermet iyimpahla ephukayo, ngakho-ke gwema ukungqubuzana lapho uyisebenzisa, futhi ungenzi ukugqama kwe-coating.

2. Ukunciphisa ukuchayeka emoyeni: Ama-electrode e-graphite kufanele agcinwe endaweni eyomile nengenawo umoya ukuze kuvinjelwe ukuchayeka kumswakama nomoya.Lokhu kuzosiza ukuvimbela i-oxidation.

3. Ukwehlisa izinga lokushisa lokusebenza: Ukusebenzisa i-electrode ekushiseni okuphansi kunganciphisa amathuba okuba ne-oxidation.Lokhu kungafezwa ngokunciphisa amandla amanje noma ukwandisa isikhala se-electrode.

4. Ukusebenzisa igesi evikelayo: Igesi evikelayo efana ne-argon noma i-nitrogen ingasetshenziswa ngesikhathi sokusebenza ukuvimbela i-oxidation.Igesi isiza ukudala umoya ovikelayo ozungeze i-electrode.

5. Ukuhlanza okufanele: Ukuhlanzwa kahle kwe-electrode ngaphambi kokusebenza kungasusa noma yikuphi ukungcola noma ukungcola okungabangela i-oxidation.

Ububanzi bokusebenza: Ifanele imikhiqizo yegraphite efana nama-graphite electrode, i-anode carbon blocks, izitshalo ze-electrolytic aluminium, isikhunta se-graphite, ama-graphite crucibles, neminye imikhiqizo ye-graphite evala uphawu engaphezulu kwe-anti-oxidation, ukuvala i-anti-corrosion, ukwandisa impilo yemikhiqizo ye-graphite ngo-at. okungenani 30%, okwandisa amandla impahla.
