Ng’anjo yapakati pafupipafupi Oxidation Steelmaking Process

M’zaka zaposachedwapa, wapakatikati pafupipafupi ng’anjo sikunangogwiritsidwa ntchito kwambiri popanga zitsulo ndi ma aloyi, komanso yakhala ikupangidwa mofulumira pakupanga chitsulo chosungunula, makamaka m’mabwalo opangira zinthu ndi ntchito zanthawi zonse. Zida zothandizira za ng’anjo yapakatikati ya ng’anjo zikuphatikizapo: magetsi ndi gawo loyendetsa magetsi, gawo la thupi la ng’anjo, chipangizo chotumizira ndi madzi ozizira.

Oxidation steelmaking ndondomeko

Nthawi zambiri, ng’anjo ya ng’anjo yamchere imagwiritsidwa ntchito, yomwe imakhala ndi kulolerana kwakukulu pakulipiritsa. Kuphatikizika kwa mtengowo kumatha kukhala ndi mtunda waukulu kuchokera kumapeto kwake, koma sikuli koyenera kuti pakhale ntchito zazikulu za decarburization, desulfurization ndi dephosphorization, chifukwa kuwomba kwa okosijeni ndikosavuta kuyika pachiwopsezo cha ng’anjo. kuvala ngozi; ntchito zambiri za desulfurization zidzatalikitsa nthawi yochepetsera ntchito ndikuyambitsa dzimbiri lalikulu la ng’anjo, kapena kuchepetsa zaka za ng’anjo kapena kuyambitsa ngozi. Chifukwa makutidwe ndi okosijeni steelmaking ndondomeko ali ndi makutidwe ndi okosijeni kuwira ndondomeko, akhoza bwino kuchotsa mitundu yonse ya inclusions ndi mpweya woipa mu zitsulo, ndi kukhathamiritsa ntchito zakuthupi. Komabe, njira ya ndondomekoyi ndi yovuta, ndipo wogwiritsa ntchito amafunika luso lapamwamba laukadaulo, ndipo kupatuka kwapang’onopang’ono kumakhala kwakukulu, kukhazikika kumakhala kovutirapo, ndipo moyo wa ng’anjo ya ng’anjo ndi zida ndizochepa.
