Taw qhia
FeSi 65 thiab FeSi 75 alloys yog tsim nyob rau hauv hluav taws xob rauv, yog li cov neeg yuav khoom qee zaum xav tias cov txheej txheem smelting yuav luag zoo tib yam. Cov hauv paus ntsiab lus zoo sib xws, tab sis cov kev khiav hauj lwm tsis sib txawv. Txhawm rau tsim cov khoom siv silicon siab dua xws li FeSi 75, cov tuam txhab feem ntau siv cov txheej txheem nruj dua thiab qhov sib txawv me me hauv cov khoom siv raw, cov khoom siv hluav taws xob, kev siv tshuab casting thiab crushing / kev tshuaj ntsuam ua ntau pom. Yog tias koj siv ferrosilicon ua ib qho tseem ceeb hauv koj qhov kev tsim khoom, kev nkag siab txog qhov sib txawv ntawm cov txheej txheem smelting yuav pab koj kwv yees qhov sib xws hauv cov khoom zoo thiab tsis txhob "tib hom npe, txawv tus cwj pwm" xav tsis thoob.
1) Dab tsi yog tag nrho smelting puag?
Q1: Puas yog ferrosilicon 65 thiab 75 tsim los siv tib lub thev naus laus zis?
O1: Yog. Ob qho khoom lag luam feem ntau yog tsim nyob rau hauv submerged arc furnaces (SAFs) los ntawm smelting silicon-muaj cov ntaub ntawv (feem ntau quartz-based) siv cov pa roj carbon txo cov neeg ua haujlwm thiab cov khoom siv hlau. Lub molten alloy yog drained, solidified, ces crushed thiab sieved kom tau marketable feem. Thaum xub thawj siab ib muag, cov txheej txheem zoo li qub. Hauv kev xyaum, thaum tsim FeSi 75, cov ntsiab lus silicon siab dua tau ua tiav, yog li kev siv zog ntawm kev tswj thiab rhiab heev rau kev hloov pauv.
Q2: Qhov twg melting theem ncaj qha cuam tshuam rau cov khoom kawg tau txais los ntawm cov neeg siv khoom?
A2: Rau cov neeg yuav khoom, qhov tseem ceeb tshaj plaws cuam tshuam rau cov khoom zoo yog:
- muaj pes tsawg leeg ntawm feedstock (qhov xwm ntawm impurities),
- stability ntawm lub cub tawg ua hauj lwm (variation ntawm parameters ntawm batch rau batch),
- casting thiab casting tshuab (sab hauv qauv thiab oxidation xeev),
- sib tsoo / sifting (qhov loj me thiab cov ntsiab lus ntawm cov feem zoo),
- kev ntim khoom thiab kev thauj mus los (tsim cov feem me me thaum thauj).
2) Yuav ua li cas hloov lub hom phiaj cov ntsiab lus silicon cuam tshuam rau txoj hauv kev rau cov txheej txheem smelting?
Q3: Vim li cas qhov kev tsim khoom ntawm FeSi 75 feem ntau xav tau kev tswj hwm nruj dua li FeSi 65?
A3: Cov qib siab ntawm silicon feem ntau xav tau kev tswj xyuas kom zoo dua ntawm qhov cub hluav taws xob, txo cov xwm txheej, thiab kev ua haujlwm tsis tu ncua kom ua tiav lub hom phiaj kev ua tau zoo yam tsis muaj kev hloov pauv ntau dhau. Qhov sib txawv me ntsis ntawm qhov sib piv ntawm cov khoom siv, lub zog lossis lub tshuab hluav taws xob ruaj khov tuaj yeem ua rau muaj kev hloov pauv hauv cov ntsiab lus silicon lossis txo cov khoom tawm los. Yog li ntawd, ntau tus neeg tsim khoom pom kev tsim khoom ntawm FeSi 75 raws li ib qho kev pab cuam nrog cov kev cai nruj dua, thiab tsis yog ib yam khoom uas muaj cov ntawv sib txawv.
Q4: Puas muaj cov ntsiab lus silicon ntau dua yuav tsum tau siv lwm cov ntaub ntawv raw?
A4: Feem ntau yog, tsawg kawg hauv kev xyaum. Cov neeg tsim khoom yuav xav tau qhov zoo sib xws ntawm quartz ntau dua thiab ua tib zoo xaiv cov neeg ua haujlwm kom txo tau cov kev ua haujlwm zoo ib yam thaum ua tiav cov ntsiab lus siab dua silicon. Qhov no tuaj yeem cuam tshuam tus cwj pwm ntawm impurities. Txawm li cas los xij, qhov no tsis yog universal; Cov nroj tsuag sib txawv muaj qhov sib txawv ntawm qhov cub tsim thiab cov khoom siv raw khoom. Rau kev yuav khoom, qhov tseem ceeb tsis yog txoj kev xav, tab sis tus neeg muag khoom lub peev xwm los ua kom pom qhov sib xws ntawm cov khoom zoo nyob hauv cov khoom siv.
3) Cov impurities. Dab tsi hloov thiab dab tsi tseem zoo li qub?
Q5: Puas yog cov impurities txawv vim yog - qhov sib txawv ntawm cov txheej txheem smelting ntawm qib 65 thiab 75?
A5: Cov muaj pes tsawg leeg ntawm impurities nyob ntawm ntau dua ntawm cov khoom siv thiab smelting thev naus laus zis dua li qib ntawm cov hlau nws tus kheej. Txawm li cas los xij, qib 75 ferrosilicon feem ntau yog tsim rau cov neeg siv khoom uas yuav tsum tau nruj dua, yog li qee tus neeg muag khoom tswj hwm cov phosphorus thiab sulfur cov ntsiab lus ntawm lawv cov khoom qib FeSi 75 nruj dua. Cov ntsiab lus ntawm txhuas thiab calcium tuaj yeem sib txawv heev thiab feem ntau nyob ntawm qhov tshwj xeeb ntawm cov nroj tsuag tshwj xeeb. Cov neeg yuav khoom yuav tsum xav tias tsis muaj ib qho loj-haum-tag nrho cov cai thiab xyuas cov khoom zoo raws li daim ntawv pov thawj ntawm kev tshuaj xyuas los ntawm ntau pawg.
Q6: Cov impurities twg yog qhov tseem ceeb tshaj plaws rau kev qhuab qhia thev naus laus zis?
A6: Cov teeb meem feem ntau tshwm sim vim yog -batch-to-batch variability. Txawm hais tias qhov nruab nrab qhov tseem ceeb tau txais, kev hloov pauv hauv phosphorus / sulfur lossis aluminium / calcium cov ntsiab lus tuaj yeem cuam tshuam qhov kev kwv yees ntawm kev coj tus cwj pwm alloy. Ib tus neeg muag khoom nrog cov txheej txheem nruj yuav feem ntau qhia qhov sib txawv tsawg dua nyob rau ntau pawg, uas feem ntau muaj txiaj ntsig ntau dua li ib daim ntawv pov thawj tshwj xeeb ntawm kev tshuaj xyuas.
Cov lus nug nquag
Q: Puas yog FeSi 75 ferrosilicon ib txwm tsim nyob rau hauv ntau lub cub tawg dua li FeSi 65?
A: Tsis tas li. Ntau lub Hoobkas tuaj yeem tsim ob hom. Cov ntaub ntawv ruaj khov thiab ua raws li kev qhuab qhia thev naus laus zis yog qhov tseem ceeb.
Q: Puas tuaj yeem ruaj khov FeSi 65 outperform FeSi 75?
A: Yog lawm, yog tias FeSi 65 muaj kev tswj qhov loj me me thiab cov ntsiab lus qis dua, silicon rov ua haujlwm tau zoo dua.
Q: Dab tsi yog txoj hauv kev ceev tshaj plaws rau tus neeg yuav khoom los xyuas cov txheej txheem kev ruaj ntseg?
A: Thov ntau Daim Ntawv Pov Thawj Kev Ntsuam Xyuas Tsis ntev los no (COAs) rau cov khoom sib txawv thiab sib piv qhov sib txawv, tsis yog qhov nruab nrab xwb.
