Ferrosilicon (FeSi) yog siv rau hauv ntau cov txheej txheem kev lag luam, tab sis cov qib sib txawv tsis tas yuav ua haujlwm rau tib lub hom phiaj tib yam. Cov neeg yuav khoom feem ntau pom cov qib zoo liFeSi75, FeSi72, thiab FeSi65, thiab lo lus nug tseem ceeb dhau los ua: "Yuav ua li cas hloov pauv thaum qib hloov?" Hauv cov ntsiab lus yooj yim, qib siab dua muab kev ua haujlwm zoo dua thiab huv dua metallurgical, thaum cov qib qis tuaj yeem raug nqi ntau dua -tus phooj ywg rau cov ntawv thov yooj yim. Hauv qab no yog cov lus nug uas cov neeg yuav khoom nug thaum xaiv qib.
Kev lag luam Q&A: Dab tsi yog qhov kev siv tseem ceeb thiab kev ua haujlwm ntawm cov qib sib txawv ntawm Ferrosilicon?
Q1: Lub luag haujlwm tseem ceeb ntawm ferrosilicon hauv steelmaking yog dab tsi, tsis hais qib twg?
Thoob plaws txhua qib, cov haujlwm tseem ceeb ntawm ferrosilicon yogdeoxidation- tshem tawm oxygen los ntawm cov hlau molten. Oxygen tuaj yeem tsim kev suav nrog thiab cov ntsiab lus tsis muaj zog hauv cov hlau, yog li deoxidation yog qhov tseem ceeb rau kev ua kom huv thiab ruaj khov.
Dhau li deoxidation, ferrosilicon kuj ua haujlwm ua ib qhosilicon alloying qhov chaw, pab kho cov tshuaj muaj pes tsawg leeg thiab txhim kho cov khoom zoo li lub zog, hardness, thiab oxidation kuj.
Yog li lub hauv paus yog tib yam rau txhua qib:
ntxuav cov hlau + ntxiv silicon hauv txoj kev tswj tau.
Q2: Cov haujlwm txawv li cas ntawm FeSi75 thiab FeSi72?
Qhov txawv yog feem ntau nyob rau hauvkev ua tau zoo zog thiab stability, tsis nyob rau hauv lub luag hauj lwm.
FeSi 75muaj ntau dua silicon cov ntsiab lus thiab feem ntau nruj impurity tswj. Nws nyhav kom xa cov silicon ruaj khov dua thiab ua kom zoo dua cov txiaj ntsig metallurgical. Tias yog vim li cas nws yog dav siv nyob rau hauv siab dua - yuav tsum tau steel qib, nrog rau cov hlau alloy thiab cov txheej txheem rhiab rau impurities.
FeSi72yog me ntsis qis hauv silicon thiab feem ntau pheej yig dua. Hauv ntau qib steel hlau (tsim steel, txheem carbon steel), FeSi72 ua tau zoo kawg nkaus thiab tuaj yeem txo nqi.
Hauv kev yuav khoom txhua hnub, ntau lub mills kho FeSi75 raws li "kev ua tau zoo-thawj" xaiv thiab FeSi72 raws li "tus nqi-" kev xaiv.
Q3: Dab tsi yog qhov kev siv ntawm FeSi75?
FeSi75 feem ntau siv hauv:
Steelmaking qhov twgruaj khov silicon rov qabyog qhov tseem ceeb
Cov ntawv thov kom muaj zog deoxidation
Cleaner steel qib qhov twg impurity tswj teeb meem
Qee qhov siab -purity lossis siab dua- ua tiav cov txheej txheem metallurgical
Nws kuj tseem muaj kev lag luam thoob ntiaj teb vim nws haum rau ntau hom rauv thiab muaj cov txiaj ntsig zoo ntawm cov kab ntau lawm. Ntau lub mills hlau nyiam FeSi75 thaum lawv xav tau tsawg dua kev xav tsis thoob hauv chemistry tswj.
Q4: Qhov twg yog FeSi65 feem ntau siv, thiab vim li cas cov neeg yuav khoom xaiv nws?
FeSi65 feem ntau xaiv thaum daim ntawv thov raug nqi ntau dua -tsav thiab tsis xav tau qhov kev ua tau zoo tshaj plaws deoxidation. Cov kev siv ib txwm muaj xws li:
Foundries thiab cam khwb cia hlau ntau lawm
Basic steel qib
Cov xwm txheej uas qhov kev hloov kho silicon tuaj yeem ua tiav nrog cov ntim ntau dua
Qee cov kab ntau lawm uas siv FeSi ua cov khoom siv silicon tab sis tsis muaj impurity heev -rhiab heev
FeSi65 tuaj yeem yog qhov kev xaiv siv tau vim tias nws txo cov nqi yuav khoom ib tuj, txawm hais tias nws yuav xav tau cov nyiaj siv ntau dua kom ua tiav tib lub tswv yim silicon piv rau FeSi75.
Q5: Yuav ua li cas cov neeg yuav khoom xaiv ntawm cov qib sib txawv rau tus nqi zoo tshaj?
Cov neeg yuav khoom feem ntau txiav txim siab raws li peb lub ntsiab lus yooj yim:
Hlau los yog casting yuav tsum tau: Siab dua -qib steel feem ntau nyiam FeSi75.
Impurity rhiab heev: Yog tias P, S, Al, lossis C yuav tsum tau tswj nruj me ntsis, FeSi75 muaj kev nyab xeeb dua.
Tus nqi phiaj: Rau cov qauv hlau lossis cov chaw tsim khoom, FeSi72 lossis FeSi65 tuaj yeem txo tus nqi yam tsis muaj kev puas tsuaj rau kev ua haujlwm ntau dhau.
Hauv kev xyaum tiag tiag, qee cov nroj tsuag siv kev sib xyaw ua ke -FeSi75 rau siab dua- cov kab ntau lawm thiab FeSi72/65 rau cov khoom siv dav dav. Txoj hauv kev no pab tswj tus nqi thaum tseem ua kom zoo ruaj khov nyob qhov twg nws tseem ceeb.
