Taw qhia
Thaum cov neeg yuav khoom nug dab tsi ferrosilicon 45 yog ua los ntawm, lawv feem ntau tsis yog txhais tau tias "Si thiab Fe." Hauv kev xyaum, qhov tshwm sim ntawm kev siv ferrosilicon nyob ntawm cov khoom siv raw, smelting technology thiab cov txheej txheem impurities uas nkag mus rau hauv cov hlau nrog silicon. Hauv qab no kuv yuav saib dab tsi ferrosilicon yog ua los ntawm, dab tsi nws yog tsim nyog los xyuas nyob rau hauv lub COA thiab dab tsi tej yam kev mob nyob rau hauv lub PO pab ua tus xa khoom kwv yees.
1) Cov qib ferrosilicon feem ntau yog cais li cas?
Nqe Lus Nug 1: Ferrosilicon 45 yog dab tsi los ntawm theem pib?
Teb 1:Ferrosilicon 45 - yog ib qho hlau- silicon alloy uas feem ntau muaj ntawm silicon (Si) thiab hlau (Fe). Hauv kev xyaum ua lag luam, tus lej "45" feem ntau yog hais txog qhov nruab nrab ntawm silicon: Si yog nyob ib ncig ntawm "mid 40%" ntau yam, thiab Fe ua rau tus so. Cov hlau yog tsim nyob rau hauv lub cub hluav taws xob, tom qab ntawd nchuav, txias thiab ua tiav rau hauv cov seem uas xav tau (khoom lossis hmoov).
Nqe Lus Nug 2: Cov ntsiab lus dab tsi feem ntau muaj dua li Si thiab Fe?
Teb 2:Ntxiv nrog rau Si thiab Fe, FeSi 45 feem ntau muaj me me ntawm C, Al, Ca, P thiab S, nrog rau cov kab ke - nyob ntawm cov khoom siv raw thiab cov khoom siv rauv taws. Rau cov neeg yuav khoom, cov no tsis yog "cov ntsiab lus me": cov txheej txheem impurities cuam tshuam rau kev ruaj ntseg thiab kev pheej hmoo ntawm kev sib txawv hauv kev tsim khoom.
Nqe Lus Nug 3: Vim li cas cov neeg yuav khoom tham ntau txog impurities hauv ferrosilicon 45?
Teb 3:Vim impurities tsim cov nqi zais. Ob tus neeg muag khoom tuaj yeem muag "FeSi 45", tab sis nrog P / S siab dua lossis tsis ruaj khov Al / Ca, tus neeg yuav khoom yuav muaj ntau qhov sib txawv ntawm cov txiaj ntsig, kev hloov kho ntau dua thiab muaj feem ntau ntawm kev tsis sib haum xeeb. Ntawd yog, ferrosilicon yog ua los ntawm Si thiab Fe, tab sis kev pheej hmoo ua lag luam feem ntau "s zaum" hauv cov khoom me me.
2) Yuav ua li cas FeSi 45 yog tsim thiab vim li cas nws hloov "nws yog dab tsi"
Nqe Lus Nug 4: Yuav ua li cas yog ferrosilicon 45 feem ntau tsim?
Teb 4:Feem ntau cov qib ntawm FeSi yog tsim nyob rau hauv hluav taws xob furnaces los ntawm silicon-muaj raw cov ntaub ntawv (feem ntau quartz keeb kwm) thiab hlau qhov chaw. Tom qab ntawd cov yaj yog tso tawm, cov alloy solidifies, tom qab uas nws yog crushed thiab sorted los ntawm feem. Txoj hauv kev no yog qhov tseem ceeb vim tias nws cuam tshuam rau saum npoo oxidation, qauv, thiab nyiam ntawm cov khoom los tsim nplua thaum overloaded.
Nqe Lus Nug 5: Vim li cas tib lub npe tuaj yeem qhia tus cwj pwm txawv?
Teb 5:Feem ntau yog vim -peb yam:
- Cov "tus ntiv tes" ntawm cov khoom siv raw - impurity profile rov ua cov ntaub ntawv nkag.
- Melting xyaum thiab tswj kev ruaj ntseg - yuav cuam tshuam batch-rau-batch variation.
- Kev ua lub cev thiab ntim khoom - crushing, tshuaj ntsuam thiab ntim txiav txim siab npaum li cas thiab PSD stability.
Yog tias koj qhov xwm txheej nyob ntawm cov hmoov (xws li DMS), cov lus nug ntawm "nws yog dab tsi" nthuav mus rau physics: PSD, plua plav, thiab tawg tsis kam. Yog li ntawd, ntau tus neeg yuav khoom xav txog FeSi 45 hmoov ua "cov khoom siv engineering" es tsis yog cov khoom los ntawm lub npe.
3) Yam dab tsi tus neeg yuav khoom yuav tsum tau sau tseg thiab kuaj tawm tsam COA
Nqe Lus Nug 6: Kuv yuav thov dab tsi hauv COA rau ferrosilicon 45?
Teb 6:Yam tsawg kawg nkaus, Si thiab cov impurities uas tseem ceeb rau koj daim ntawv thov, feem ntau C, P, S, Al thiab Ca, nrog rau qhov tseeb txuas mus rau batch (batch ID). Yog tias koj tab tom yuav FeSi 45 hmoov lossis sieved feem, nws ua rau kev pom zoo rau daim ntawv qhia PSD lossis cov txheej txheem kuaj vim tias lub cev tsis sib haum xeeb feem ntau ua rau poob ntau dua li cov tshuaj dispersion.
Nqe Lus Nug 7: Cov impurities feem ntau tseem ceeb tshaj plaws rau kev txiav txim siab yuav khoom?
Teb 7:Nyob ntawm koj qhov kam rau ua, tab sis feem ntau yog qhov tseem ceeb yog:
- P thiab S - yog "kev nplua" ib txwm muaj rau kev lag luam metallurgy thiab cov neeg siv khoom nrog cov qauv nruj.
- Al thiab Ca - tuaj yeem cuam tshuam cov txheej txheem kev ruaj ntseg thiab cov lus qhia tshwj xeeb.
- C - yog qhov tseem ceeb qhov twg cov pa roj carbon tsawg lossis cov tshuaj tiv thaiv ruaj khov xav tau.
Txoj cai ntawm tus ntiv tes xoo: Ntsuam xyuas kis thoob plaws ntau pawg. Ib qho COA yuav yog "zoo tagnrho", tab sis peb - tsib COA los ntawm cov khoom sib txawv yuav qhia qhov kev ruaj ntseg tiag tiag ntawm kev tsim cov ferrosilicon.
Nqe Lus Nug 8: Yuav ua li cas tus neeg yuav khoom tuaj yeem sau tau PO specification rau FeSi 45?
Teb 8:Siv cov lus ntsuas tau:
- Chemistry: Si ntau lossis tsawg kawg Si ntxiv rau qhov siab tshaj plaws rau cov impurities tseem ceeb.
- Physics: qhov loj me rau pob lossis PSD rau cov hmoov, ntxiv rau qhov kev nplua nyuaj nrog lub hauv paus txhais.
- Traceability: Ntau cov cim ntawm lub hnab thiab COA ua raws.
- Tswj thiab thov: sampling method and claims window.
Txoj kev no koj tiv thaiv kev sib cav feem ntau: "lub hom phiaj yog tib yam, tab sis tus cwj pwm txawv."
Cov lus nug nquag
Nqe Lus Nug: Puas yog FeSi 45 - tib yam li FeSi 44 lossis 46?
Teb: Si tej zaum yuav nyob ze rau theem, tab sis tsis tuaj yeem hloov pauv tau. Sib piv Si ntau thiab impurity txwv.
Lo lus nug: Vim li cas FeSi 45 hmoov qee zaum noj sai dua hauv DMS?
Teb: Vim yog -vim PSD drift, ntau dhau ultrafine thiab particle tawg, uas ua rau kom slurry poob.
Nqe Lus Nug: Dab tsi yog qhov kev pheej hmoo zais loj tshaj plaws thaum yuav FeSi 45?
Teb: Lub cev tsis ruaj khov (kev loj hlob ntawm kev nplua nyiaj thaum lub sijhawm thauj mus los) thiab kev hloov pauv ntawm cov impurities tseem ceeb los ntawm batch mus rau batch.
Lus Nug: Dab tsi yog qhov zoo tshaj plaws ntim rau ferro silicon 45?
Teb: Ib qho uas txo kev puas tsuaj thiab ya raws, thiab kom meej meej cov ntawv ntau rau traceability.
Nqe Lus Nug: Puas tsim nyog yuav FeSi 45 ntawm tus nqi qis tshaj?
Teb: Tsis yog ib txwm. Nws feem ntau muaj txiaj ntsig zoo los txiav txim siab tus nqi-ib - siv tau-Si suav nrog kev poob thiab tawg.
Vim li cas thiaj xaiv peb?
- Supply FeSi 45 nrog rau qhov tseem ceeb ntawm PSD thiab kev nplua nplua uas tiv thaiv kev ua haujlwm hauv cov ntawv thov hmoov.
- Kev tswj hwm ntau qhov sib xws nrog kev taug qab thiab cov neeg siv khoom zoo COA hom ntawv.
- Export ntim tsim los txo kev puas tsuaj, plua plav thiab nplua kev loj hlob hauv kev thauj mus los.
- Kev pab hauv kev tsim PO- tshuaj lom neeg thiab cov kab mob feem ntau kom lawv siv tau raws li qhov kev lees paub.
