Raw Khoom Xaiv thiab Tswj

 

Xaiv High-qib Iron Ore: Thaum lub sij hawm hlau - ua theem, qib qis hlau ore yuav qhia ntau impurities, nrog rau cov pa roj carbon. Yog li ntawd, nws yog ib qho tseem ceeb los xaiv cov qib high-qib hlau ore ntau li ntau tau. High-grade hlau ore muaj cov pa roj carbon tsawg dua impurities, uas tuaj yeem txo qhov kev taw qhia ntawm carbon los ntawm qhov chaw. Piv txwv li, cov hlau ore hauv thaj av Pilbara ntawm Australia muaj cov qib siab thiab yog ib qho kev xaiv zoo heev rau hlau - ua cov khoom siv raw. Nws muaj cov ntsiab lus hlau siab thiab tsis tshua muaj impurity (xws li carbon) cov ntsiab lus.

 

Tswjhwm - zoo Coke: Coke yog ib qho tseem ceeb txo tus neeg sawv cev hauv cov hlau - ua cov txheej txheem, tab sis nws kuj yog ib qho tseem ceeb ntawm carbon. Siv cov coke zoo thiab nruj tswj hwm nws cov koob tshuaj tuaj yeem txo cov pa roj carbon ntau. Los ntawm kev ntsuam xyuas cov ntsiab lus ntawm cov pa roj carbon ntau ntawm cov khoom sib txawv ntawm coke, xaiv cov coke nrog cov ntsiab lus carbon uas ua tau raws li cov qauv qis. Nyob rau tib lub sijhawm, txais yuav cov coke siab heev - kev sib xyaw cov txheej txheem los txhim kho qhov sib piv coke kom txo qis cov pa roj carbon ntau thaum ua kom cov hlau - ua cov tshuaj tiv thaiv zoo.

Optimizing txheej txheem Melting

 

Oxygen - saum - tshuab tshuab Converter Melting: Hauv cov hlau - ua cov txheej txheem, cov pa oxygen - sab saum toj - tshuab tshuab yog ib qho khoom siv feem ntau siv melting. Los ntawm tshuab siab - purity oxygen rau hauv lub converter, cov pa roj carbon nyob rau hauv cov hlau molten tuaj yeem hnov ​​​​mob nrog oxygen los ntawm cov tshuaj tiv thaiv oxidation, yog li txo cov ntsiab lus carbon. Txoj kev no tuaj yeem tswj hwm cov txheej txheem carbon oxidation. Raws li lub hom phiaj cov ntsiab lus carbon, kho cov pa tshuab ntim thiab lub sijhawm tshuab. Piv txwv li, thaum melting cov hlau molten yuav tsum tau rau LR Qib B shipbuilding steel daim hlau, los ntawm kev saib xyuas lub sij hawm hloov ntawm cov ntsiab lus carbon nyob rau hauv cov hlau molten, cov pa oxygen mov yog dynamically kho kom raug tswj cov pa roj carbon ntsiab lus nyob rau hauv ib tug ntau yam ntawm tsis. tshaj 0.21%.

 

Hluav taws xob Arc Rauv Melting Adjustment: Rau qhov teeb meem ntawm kev siv hluav taws xob arc rauv rau melting, nyob rau hauv thawj theem ntawm melting, qhov kev faib ua feem ntawm seem steel yuav tsim nyog nce. Cov ntsiab lus ntawm cov pa roj carbon monoxide yog qhov ruaj khov thiab qis. Los ntawm kev nce cov tswv yim ntawm cov khoom seem, cov ntsiab lus ntawm cov pa roj carbon monoxide hauv cov hlau molten tuaj yeem diluted. Meanwhile, thaum lub sij hawm melting txheej txheem, qhov kub thiab txias ib puag ncig thiab zoo stirring tej yam kev mob ntawm lub hluav taws xob arc rauv yuav siv tau los ua kom cov pa roj carbon siab reacts nrog oxidizing gas nyob rau hauv lub cub tawg, ntxiv txo cov pa roj carbon ntsiab lus.
