Zipangizo Zosungunulira Ng'anjo Zokhala ndi Mpweya Wautali wa Ferrochrome Chithunzi Chowonetsedwa — Zipangizo Zosungunulira Ng'anjo Zokhala ndi Mpweya Wautali wa Ferrochrome

Mafotokozedwe Akatundu

Njira zopangira ferrochrome yokhala ndi mpweya wambiri zimaphatikizapo njira ya ng'anjo yamagetsi, njira ya shaft furnace (blast furnace), njira ya plasma ndi njira yochepetsera kusungunuka. Njira ya shaft furnace tsopano imapanga chromium alloy yotsika (Cr < 30%), kuchuluka kwa chromium (monga Cr> 60%) ya njira yopangira shaft furnace kukadali mu gawo lofufuza; njira ziwiri zomalizazi zikufufuzidwa mu njira yatsopano; chifukwa chake, njira zambiri zamalonda za ferrochrome yokhala ndi mpweya wambiri komanso ferrochrome yopangidwanso zimagwiritsidwa ntchito popanga ng'anjo yamagetsi (mineral furnace).

Zambiri za malonda

Lumikizanani Tsopano

Kusungunula ng'anjo yamagetsi kuli ndi makhalidwe awa

(1) Ng'anjo yamagetsi imagwiritsa ntchito magetsi, gwero lamphamvu loyera kwambiri. Magwero ena amagetsi monga malasha, coke, mafuta osakonzedwa, gasi wachilengedwe, ndi zina zotero mosakayikira adzabweretsa zinthu zodetsa zomwe zikugwirizana nazo mu ndondomeko ya zitsulo. Ng'anjo yamagetsi yokha ndi yomwe ingapange zitsulo zoyera kwambiri.

(2) Magetsi ndiye gwero lokhalo la mphamvu lomwe lingapeze kutentha kwambiri mwachisawawa.

(3) Ng'anjo yamagetsi imatha kuzindikira mosavuta zinthu zomwe zimachitika chifukwa cha kutentha monga kupanikizika pang'ono kwa mpweya ndi kupsinjika pang'ono kwa nayitrogeni komwe kumafunikira ndi zinthu zosiyanasiyana monga kuchepetsa, kuyeretsa ndi kusungunula nitriding.
