1. Hlau ore
Hlau ore yog cov khoom siv thawj hauv cov hlau steel. Nws yog lub ntuj tsim ntawm hlau (FE), feem ntau muaj cov hlau oxides xws li cov hlau nplaum, hematite, thiab limonite. Hlau Ore Mining thiab kev ua yog thawj qhov txuas hauv cov qauv hlau, thiab cov txiaj ntsig ncaj qha thiab cov txiaj ntsig ntawm cov txheej txheem smelting tom ntej. Thaum lub sij hawm smelting txheej txheem, hlau ore undergoes ua ntej- kev kho kom zoo li cov neeg sawv cev ua ke xws li Coke rau kev tawm tsam txo los tsim cov hlau npua.
2. Coke
Coke yog lwm cov khoom tseem ceeb hauv steel ntau lawm, feem ntau siv los ua tus sawv cev txo tus neeg sawv cev thiab cov cua sov hauv lub tshuab tawg. Tsis pub dhau lub moj tej tawg, coke reacts nrog oxygen los ua cov pa roj carbon dioxide, tso ib qho tseem ceeb ntawm cov cua sov tsim nyog. Qhov tseem ceeb tshaj, cov pa roj carbon hauv coke sib txuas nrog oxygen nyob rau hauv cov hlau monoxide, uas yog qhov kawg ua kom npua hlau. Yog li ntawd, qhov zoo thiab ruaj khov mov ntawm Coke yog qhov tseem ceeb rau cov steel ntau lawm.
3. Ntu Khoom Siv Raw
Ntxiv rau cov ore hlau thiab coke, ntau lawm cov khoom siv rawestone, suav nrog limestone, dolomite, manganese ore, thiab chromium ore. Cov khoom siv raw ua lub luag haujlwm ua lub luag haujlwm hauv kev kho cov khoom slag, tshem tawm impurities, thiab txhim kho cov qauv zoo thaum lub sijhawm smelting. Piv txwv li, limo kom sov los tsim cov tshuaj calcium, thiab lwm yam hauv cov hlau, uas yog qhov ntawd tau tawm thiab ua kom huv cov hlau Molten.
