Njira yochepetsera kugwiritsa ntchito ma electrode
M'zaka zaposachedwa, ndi chitukuko champhamvu cha makampani China magetsi ng'anjo zitsulo, komanso zofunika kupulumutsa mphamvu ndi kuchepetsa mowa akatswiri ndi akatswiri kunyumba ndi kunja kutsiriza njira zothandiza motere:
1. Anti-oxidation njira ya madzi kupopera graphite electrode
Kupyolera mu kafukufuku kuyesera, kupopera mbewu mankhwalawa odana ndi makutidwe ndi okosijeni njira padziko maelekitirodi watsimikizira bwino kwambiri kusiya mbali makutidwe ndi okosijeni wa elekitirodi graphite, ndi odana ndi okosijeni mphamvu chiwonjezeke ndi 6-7 zina. Mukamagwiritsa ntchito njirayi, kumwa kwa electrode kwatsika mpaka 1.9-2.2kg kusungunula tani yachitsulo.
2. Elekitirodi yopanda kanthu
M’zaka zaposachedwapa, Western Europe ndi Sweden ayamba kugwiritsa ntchito ma elekitirodi opanda kanthu popanga ng’anjo za miyala ya ferroalloy. Maelekitirodi opanda pake, mawonekedwe a silinda, nthawi zambiri amakhala opanda kanthu mkati mwake osindikizidwa ndi mpweya wa inert. Chifukwa cha kunyowa, zophika zimakhala bwino ndikupangitsa mphamvu ya ma elekitirodi kukhala apamwamba. Nthawi zambiri, imatha kupulumutsa maelekitirodi ndi 30% -40%, mpaka 50% kwambiri.
3.DC ng'anjo ya arc
DC electric arc ng'anjo ndi mtundu watsopano wa ng'anjo yamagetsi yosungunula yomwe yangopangidwa kumene padziko lapansi m'zaka zaposachedwa. Kuchokera pazomwe zafalitsidwa kunja, DC arc ng'anjo ndi imodzi mwa njira zothandiza kwambiri zochepetsera kugwiritsa ntchito ma electrode. Nthawi zambiri, kugwiritsa ntchito ma elekitirodi kumatha kuchepetsedwa ndi 40% mpaka 60%. Malinga ndi malipoti, kugwiritsa ntchito ma graphite electrode mung'anjo yamagetsi yayikulu kwambiri ya DC kwachepetsedwa kukhala 1.6kg/t.
4.Electrode pamwamba zokutira luso
Ukadaulo wokutira wa Electrode ndiukadaulo wosavuta komanso wogwira mtima wochepetsera kumwa ma elekitirodi, nthawi zambiri amatha kuchepetsa kugwiritsa ntchito ma elekitirodi pafupifupi 20%. Zida zokutira zama elekitirodi zomwe zimagwiritsidwa ntchito nthawi zambiri ndi aluminiyumu ndi zida zosiyanasiyana zadothi, zomwe zimakhala ndi kukana kwa okosijeni mwamphamvu pa kutentha kwambiri ndipo zimatha kuchepetsa kugwiritsa ntchito makutidwe ndi okosijeni pamtunda wa mbali ya electrode. Njira yopangira ma elekitirodi makamaka ndi kupopera mbewu mankhwalawa ndi kupera, ndipo njira yake ndi yosavuta komanso yosavuta kugwiritsa ntchito. Ndi njira yomwe imagwiritsidwa ntchito kwambiri poteteza ma electrode.
5. Elekitirodi yolowetsedwa
Dikirani maelekitirodi mu njira yamankhwala kuti mupangitse kuyanjana kwamankhwala pakati pa ma elekitirodi pamwamba ndi othandizira kuti ma elekitirodi azitha kukana kutentha kwambiri kwa okosijeni. Ma elekitirodi amtunduwu amatha kuchepetsa kugwiritsa ntchito ma elekitirodi pafupifupi 10% mpaka 15%.
