Dab tsi yog cov ntaub ntawv raw rau ferrosilicon?
Ferrosilicon (FESI) yog FERROALLOY muaj cai feem ntau ntawmHlau (fe) thiab silicon (si), Siv feem ntau rau deoxidation thiab alloying hauv steelmaking. Cov ntaub ntawv raw rau ferrosilicon ntau lawmSilicon - bearing ores, txo cov neeg sawv cev, thiab cov khoom siv hlauCov. Hauv qab no yog cov ncauj lus kom ntxaws ntawm cov khoom tseem ceeb:

|
Hom Phiaj Hauv Fesi Ntau Lawm
|
|
Silicon Dioxide (Sio₂) (Quartzite lossis silica xuab zeb)
|
98-99% ntshiab sidio₂ (lub ntsiab silicon qhov)
|
FRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRURISH ROBRA pob zeb los yog xuab zeb
|
Muab silicon rau kev ua aliaying; reacts nrog carbon los ua silicon.
|
|
Txo tus neeg saib xyuas (metallurgical coke lossis thee)
|
Carbon - rich cov khoom (80-90% cov roj carbon)
|
|
Txo lub suab seev rau silicon (si) ntawm qhov kub.
|
|
Hlau Los Ntawm Cov Hlau (Seem Hlau Los Yog Npua Hlau)
|
|
Steel seem los yog npua hlau
|
Khoom siv hlau los ua ferroalloy (FESI).
|
|
Flux (limestone lossis dolomite)
|
Calcium carbonate (caco₃) lossis magnesium carbonate (mgco₃)
|
Limestone / dolomite Mines
|
Tshem tawm impurities (piv txwv li, alumina, silica) li slag.
|
|
Refractory Cov Khoom Siv (Silica Cib, magnesite)
|
Thaum tshav kub kub -} Cov ntaub ntawv resistant
|
Refractory Cov Chaw Muag Khoom
|
Cov kab furnaces los ua kom muaj kev kub siab (~ 1600-1800 degree).

Cov ntsiab lus tseem ceeb ntawm cov khoom siv raw:
Silicon Dioxide (Sio₂):Thawj qhov chaw ntawm silicon, feem ntau yog muab los ntawmHigh - purity quartzite(98% + siio₂).
Txo tus neeg saib xyuas: Metallurgical Coke(Los ntawm cov thee) lossisRoj av cokeYog siv los txo sio₂ rau silicon ntawm carbothermic txo.
Hlau Los: Steel seem los yog npua hlauMuab cov hlau tsim nyog los ua ferrosilicon (Fesi).
Flux (limestone / dolomite):Pab tshem tawm impurities los ntawm kev sib sauSlag (calcium silicate, aluminate).
Refractories: Silica cib lossis magnesiteYog siv los ntawm kab hluav taws xob arc ua kom sov.
TusCov ntsiab lus carbon nyob rau hauv tus neeg sawv cev txoCuam tshuam qhov kawg silicon purity, thaumFlux XaivCuam tshuam txog kev nplua tsim thiab raug tshem tawm kev raug tshem tawm.
