Cov yam ntxwv tseem ceeb ntawmferrosilicon alloysyog txiav txim los ntawm lawv cov ntsiab lus silicon. Cov khoom uas muaj cov ntsiab lus sib txawv ntawm silicon (tsawg silicon<20%, medium silicon 45%-65%, high silicon 72%-90%) show significant differences in deoxidation efficiency, alloying effect, and cost. Precisely matching the silicon content is key to ensuring production efficiency and product quality in industries such as steel, casting, and chemicals.

| Siab Silicon 72% -90% | FeSi72, FeSi75, FeSi90 | 70%-77%/23%-30%;72%-80%/20%-28%;88%-92%/8%-12% | Tsawg dua lossis sib npaug li 1.5% / Tsawg dua lossis sib npaug li 0.05% / Tsawg dua lossis sib npaug 0.04% (FeSi90 Tsawg dua lossis sib npaug li 1.0% / Tsawg dua lossis sib npaug 0.03% / Tsawg dua lossis sib npaug li 0.03%) | High deoxidation efficiency thiab purity zoo heev |
Tsawg silicon ferrosilicon alloys (silicon cov ntsiab lus hauv qab 20%)
Tsawg silicon ferrosiliconalloy muaj zoo ductility thiab plasticity, thiab kuj muaj qee lub zog. Nws yog tsuas yog siv nyob rau hauv kev tsim cov hlau alloy tshwj xeeb, xws li stainless hlau, hnav-cov hlau tsis muaj zog, thiab lwm yam, uas tuaj yeem txhim kho corrosion kuj thiab hnav tsis kam ntawm cov hlau tshwj xeeb thaum txo cov nqi hlau.
Nruab nrab silicon ferrosilicon alloys
Silicon cov ntsiab lus ntawm txog 45% (FerroSilicon 45%): Nws yog ib qho khoom siv ferrosilicon alloy. Nws tuaj yeem siv ua ib qhodeoxidizernyob rau hauv steelmaking, uas tuaj yeem tshem tawm cov pa oxygen los ntawm cov hlau molten, thiab tuaj yeem ua kom lub zog thiab hardness ntawm cov hlau mus rau qee yam thiab txhim kho cov hlau zoo. Nws tuaj yeem txhawb nqa graphitization hauv cam khwb cia hlau, txhim kho qhov toughness thiab lub zog ntawm cam khwb cia hlau, thiab txo qhov nyiam ntawm cov hlau cam khwb cia hlau. Nws yog feem ntau siv nyob rau hauv zus tau tej cov cam khwb cia hlau qhov chaw.
Silicon cov ntsiab lus ntawm txog 65% (FerroSilicon 65%): Nws tuaj yeem txhim kho lub zog, hardness thiab hnav tsis kam ntawm cov hlau. Nws tuaj yeem siv ua ib qhoalloying tus neeg sawv cev rau kev tsim khoom ntawm ntau hom hlau. Nws kuj tseem siv tau los ua tus neeg sawv cev txo qis rau kev tsim cov ferromolybdenum, ferrovanadium thiab lwm yam ferroalloys. Nws kuj tau siv ntau zaus hauv kev tsim cov hlau zoo tib yam thiab qis - alloy steels uas muaj zog thiab hardness yuav tsum tau.
High silicon ntsiab lus ferrosilicon alloy
Silicon cov ntsiab lus ntawm txog 72% (FerroSilicon 72%): Nws muaj cov yam ntxwv ntawm tus nqi siab -kev ua tau zoo thiab siv dav hauv kev tsim cov hlau zoo tib yam. Nws tuaj yeem txhim kho kev ua tau zoo thiab cov khoom siv hluav taws xob ntawm cov hlau, ua kom cov hlau yooj yim dua los txiav, forge thiab lwm yam kev ua haujlwm thaum ua, thiab txhim kho tag nrho cov kev ua haujlwm ntawm cov hlau.
Silicon cov ntsiab lus ntawm 75% thiab siab dua (FerroSilicon 75%): Nws yog feem ntau siv los tsim cov hlau tshwj xeeb, xws li cov hlau tsis muaj steel, cua sov-cov hlau tsis muaj zog, siab- ceev steel, thiab lwm yam, txhawm rau txhim kho lub zog, corrosion kuj thiab kub tsis kam ntawm cov hlau. Nws yog feem ntau siv nyob rau hauv qhov siab -kub smelting txheej txheem ntawm magnesium nyob rau hauv cov txheej txheem Pijiang los hloov magnesium nyob rau hauv CaO・MgO.
Silicon cov ntsiab lus ntawm txog 90% (FerroSilicon 90%): Nws yog siab -purityferrosilicon alloy. Nws tuaj yeem siv los tsim cov khoom siv silicone thiab lwm yam khoom siv hauv kev lag luam tshuaj thiab tuaj yeem siv los npaj cov khoom siv hluav taws xob ntshiab silicon hauv kev lag luam hluav taws xob. Nws ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom siv hluav taws xob siab thiab cov khoom siv tshuaj lom neeg.
