High Carbon Ferrochrome Kuyenga Njira Kusungunula Wapakatikati-otsika Carbon Ferrochrome

Chrome ore kuyenga mkulu mpweya ferrochrome: pamene kuyenga mkulu mpweya ferrochrome ndi chrome ore, woyenga slag ndi yaikulu mamasukidwe akayendedwe ndi apamwamba kusungunuka malo, ndipo ndondomeko smelting kutentha ayenera kukhala apamwamba. Chifukwa chake, kugwiritsa ntchito mphamvu kumakhala kwakukulu, moyo wa ng'anjo ndi waufupi, ndipo zomwe zili mu kaboni sizovuta kutsika. Kuwomba mpweya wochuluka wa carbon ferrochrome uli ndi kupambana kwakukulu, monga zokolola zambiri, zotsika mtengo, kuchira kwakukulu. Pakalipano, njira yopangira chikhalidwe kapena electro-silicon kutentha njira. Electrosilicon kutentha njira ndi kupanga zamchere slag mu ng'anjo yamagetsi pansi pa chikhalidwe cha pakachitsulo mu silicon chromium aloyi kuchepetsa chromium ndi oxides chitsulo, kuti apange otsika mpweya ferrochrome.

Kuwomba mpweya wa carbon ferrochrome wochepa: Njira yowuzira mpweya woyenga mpweya wochepa wa carbon ferrochrome pogwiritsa ntchito chipangizocho ndi chosinthira, motero chimatchedwa njira yosinthira. Malinga ndi njira zosiyanasiyana zoperekera okosijeni, kuwomba kwa okosijeni kungagawike m’mitundu inayi ya kuwomba m’mbali, kuwomba pamwamba, kuwomba pansi, kumtunda ndi pansi kuwirikiza kawiri. Dziko lathu limagwiritsa ntchito njira yosinthira kwambiri. Njira yowuzira okosijeni ndikuwuzira okosijeni mwachindunji mumadzi a carbon high-carbon ferrochrome kuti apange decarburised ndikupanga mpweya wochepa wa ferrochrome. Zinthu zazikulu zomwe zili mu carbon ferrochrome yapamwamba ndi chromium, chitsulo, silicon ndi carbon, zomwe zimatha kukhala ndi okosijeni. Ntchito yayikulu ya okosijeni yomwe imawomba mpweya wambiri wa carbon ferrochrome ndi decarbonise ndikusunga chromium. Pamene mpweya kuwomberedwa mu madzi mkulu-mpweya mpweya ferrochrome, chifukwa zili chromium ndi chitsulo nkhani zoposa 90% ya okwana kuchuluka kwa aloyi, kotero makutidwe ndi okosijeni woyamba wa chromium ndi chitsulo, ndiyeno, oxides izi adzakhala oxidised kutali. silicon mu aloyi. Chifukwa cha makutidwe ndi okosijeni a chromium, chitsulo ndi silicon, kutentha kwa dziwe losungunuka kumakula mwachangu, ndipo machitidwe a decarburisation amakula mwachangu. Kutentha kwapamwamba, ndikokomera kwambiri kwa decarburisation reaction, ndipo kumatha kulepheretsa ma oxidation reaction ya chromium, ndipo kutsika kwa carbon mu alloy kumatha kuchepetsedwa.
