Nyob rau hauv cov txheej txheem tsim ntawm JSI cov qauv kev ua kom muaj zog hlau, cov nyhuv synergistic ntawm hlau ore, seem, thiab alloys tseem ceeb heev. Hauv qab no yog cov kev hloov pauv ntawm txoj kev hloov pauv thiab cov ntsiab lus ntawm cov khoom siv raw hauv kev tsim khoom:

I. Pretreatment thiab Smelting Hlau Ore

Cov txiaj ntsig thiab kev xav tau

Iron ore (such as hematite and magnetite) is crushed and ground, then impurities like gangue are removed through magnetic separation, flotation, and other processes to obtain iron concentrate powder with an iron content of >65%. Piv txwv li, Angang Hlau tswj lub particle loj ntawm taconite concentrore hauv qab no thiab cov kev sib tsoo, ua kom haum rau cov agglomeration.

Sintering thiab pelletizing

Sumining: Hlau mloog zoo hmoov yog sib xyaw nrog limestone thiab coke hmoov, ces sintered ntawm 1200 {}} 1300 xeem ua tiav sinter. Thaum lub sijhawm txheej txheem no, kev sib tham theem xws li calcium ferrite yog tsim los ntawm cov khoom siv-theem muaj zog, txhim kho lub zog thiab permeability ntawm cov ore. Piv txwv li, Shougang Hlau nce cov sinter luv ntsuas ntsuas mus rau 83% los ntawm kev ncua cov imperites thiab kev ua kom tau zoo ore.

 

 

 

 

 

 

 

 

Pelletizing: Hlau ua kom haum hmoov yog tov nrog dej thiab bentonite los ua pellets, uas yog ces roasted ntawm 1100-1300 degree. Tus txheej txheem no oxidizes magnetite mus rau hematite thiab cov ntaub ntawv Crystal Txuas hniav, ua rau pelastal txuas nrog me me thiab lub zog mus txog 2500n ib pellet. Benxi Steel txhim kho lub pellet alkalinity rau 1.5 los ntawm kev ntxiv magnesium oxide, ua kom zoo dua mellurgical kev ua tau zoo.
