Iziko eliPhakathi leFrequency Oxidation Steelmaking Process

Kwiminyaka yakutshanje, isithando somlilo esiphakathi asizange sisetyenziswe ngokubanzi kuphela kwimveliso yentsimbi kunye ne-alloys, kodwa iye yaphuhliswa ngokukhawuleza kwimveliso yentsimbi etyhidiweyo, ngakumbi kwiindibano zocweyo zokuphosa kunye nokusebenza ngamaxesha. Izixhobo ezincedisayo zesithando somlilo esiphakathi sibandakanya: ukunikezelwa kwamandla kunye nenxalenye yokulawula umbane, inxalenye yomzimba wesithando somlilo, isixhobo sokuhambisa kunye nenkqubo yokupholisa amanzi.

Inkqubo yokwenza intsimbi ye-oxidation

Ngokuqhelekileyo, i-alkaline i-furnace lining isetyenziswa, enokunyamezela okukhulu kwintlawulo. Ukubunjwa kwentlawulo kunokuba nomgama omkhulu ukusuka ekupheleni kokubunjwa, kodwa ayikafanelekanga kwi-decarburization enkulu, i-desulfurization kunye nokusebenza kwe-dephosphorization, kuba inkqubo yokuvuthela i-oksijini ilula kakhulu ukubeka engozini i-furnace lining Iya kukhokelela kwintsimbi. ukunxiba iingozi; imisebenzi ye-desulfurization egqithisileyo iya kwandisa ixesha lokusebenza kwaye ibangele umhlwa ombi welinen yesithando somlilo, okanye unciphise ubudala beziko okanye ubangele iingozi. Ngenxa yokuba inkqubo ye-steelmaking ye-oxidation inenkqubo yokubilisa i-oxidation, inokususa ngokufanelekileyo zonke iintlobo zokufakwa kunye neegesi ezinobungozi kwintsimbi, kunye nokwandisa ukusebenza kwezinto. Nangona kunjalo, indlela yenkqubo inzima, kwaye umqhubi ufuna umgangatho wobugcisa obuphezulu, kwaye ukuphambuka kwenkqubo kukhulu, ukuzinza kubi, kwaye ubomi bomlilo wesithando somlilo kunye nezixhobo ziphantsi.
