Muelectrode ya graphitepopanga zitsulo kapena phala la anode la aluminiyamu ndi kupanga magnesiamu (electrode yosungunuka), kuti apange mafuta a coke (coke) akwaniritse zofunikira, coke ndi calcined.Kutentha kwa calcination, mafuta a coke volatiles amaonedwa kuti ndi zinthu.

(1) Chotsani chinyezi ndi zinthu zosasunthika kuzinthu zopangira

Kusakhazikika kwa zinthu zopangira kumatha kuthetsedwa ndi calcination, motero kumawonjezera kaboni wokhazikika wazinthu zopangira.Madzi muzinthu zopangira amachotsedwa ndi calcination, yomwe imathandizira kuphwanya, kuyang'anira ndikupera ntchito, kupititsa patsogolo ntchito ya adsorption ya carbon raw materials kwa binder, ndi kupititsa patsogolo khalidwe la zinthu.

(2) Kupititsa patsogolo kachulukidwe ndi mphamvu zamakina azinthu zopangira

Pambuyo calcined, carbon zinthu shrinkage mu voliyumu, kuwonjezeka kachulukidwe ndi mphamvu chifukwa cha kuchotsa volatiles, ndi kupeza bwino matenthedwe bata, motero kuchepetsa yachiwiri shrinkage wa mankhwala pa calcination.

(3) Sinthani madutsidwe wa zipangizo

Pambuyo powerengera, ma volatiles amachotsedwa, ndipo mawonekedwe a mamolekyu amasinthanso, kuchepetsa mphamvu yamagetsi yamagetsi ndikuwongolera mphamvu zamagetsi zamagetsi.Nthawi zambiri, apamwamba mlingo wa calcination, ndi bwino madutsidwe wa calcined zakuthupi.

(4) Sinthani kukana kwa okosijeni kwa zida zopangira

Pambuyo calcination, monga kutentha kwa carbon zopangira kukwera, zonyansa monga haidrojeni, mpweya ndi sulfure adzatulutsidwa motsatizana kudzera pyrolysis ndi polymerization ndondomeko, ndi ntchito mankhwala adzachepa ndi thupi ndi mankhwala katundu adzakhala wokhazikika, motero kuwongolera makutidwe ndi okosijeni. kukana kwa zipangizo.

Calcined char amagwiritsidwa ntchito kwambiri popangaelectrode ya graphite, carbon phala mankhwala, carborundum, chakudya kalasi phosphorous mafakitale, mafakitale zitsulo ndi kashiamu carbide, mwa amene graphite elekitirodi ndi ambiri ntchito.Ndipo coke popanda kupaka kuyatsa itha kugwiritsidwanso ntchito mwachindunji ku calcium carbide ngati chinthu chachikulu, kupanga silicon carbide ndi boron carbide ngati zida zogaya, komanso poponya njira ndi coke wandiweyani ndi zina.
