Cov neeg yuav khoom feem ntau nug: dab tsi qib ntawm ferrosilicon nyob ntawd thiab lawv txawv li cas. Hauv kev xyaum ua lag luam, "qib" yuav luag ib txwm txhais tau tias muaj ntau yamSithiab cov txheej txheem ntawm kev xav tau rau impurities thiab feem. Yog li, cov lus nug raug yog: qib twg ntawm ferrosilicon xaiv rau koj cov txheej txheem thiab cov kev ntsuas dab tsi los sau rau hauv PO, thiaj li tsis tau txais "zoo tib yam hauv lub npe, tab sis txawv ntawm tus cwj pwm."
1) Cov qib ferrosilicon feem ntau yog cais li cas?
Nqe Lus Nug 1: Cov qib dab tsi ntawm ferrosilicon feem ntau tshwm sim hauv kev xa tawm?
Teb 1:Feem ntauFeSi 45,FeSi 65,FeSi 72,FeSi 75. Qhov kev xaiv feem ntau muaj feem xyuam rau cov ntsiab lus ntawm silicon (Si) : qhov siab dua Si, ntau "silicon ib tuj" thiab qhov sib txawv ntawm cov khoom ntxiv kev lag luam raug txiav txim siab.
Nqe Lus Nug 2: Puas yog tib lub npe tib yam los ntawm cov neeg muag khoom sib txawv?
Teb 2:Tsis tas li. Lub npe hom - tsis yog ib qho kev qhia tiav. Qhov sib txawv tiag tiag yog tsim los ntawm kev txwv ntawm impurities (feem ntau tswjP, S, Al, Ca), batch-rau-batch stability, nrog rau pawg ntseeg thiab sib koom ntawm kev hloov me me. Rau cov neeg yuav khoom, kev kwv yees qhov tseem ceeb yog qhov tseem ceeb, tsis yog Si daim duab xwb.
2) Hom twg yog xaiv rau cov haujlwm sib txawv?
Nqe Lus Nug 3: Cov hauj lwm twg yog FeSi 45 feem ntau xaiv?
Teb 3:FeSi 45 feem ntau yog siv rau cov ntawv thov uas lub cev muaj zog ntawm cov khoom (piv txwv li, hmoov thiab granular muaj pes tsawg leeg) yog qhov tseem ceeb, thiab tsis yog cov ntsiab lus Si siab tshaj plaws. Cov neeg yuav khoom no muaj cov cim tseem ceeb -PSD, feem ntawm kev nplua, tuav kev poob thiab kev ruaj ntseg hauv kev siv.
Nqe Lus Nug 4: Qhov twg yog FeSi 65, FeSi 72 thiab FeSi 75 feem ntau siv?
Teb 4:Cov qib no tau siv dav hauv metallurgy raws li qhov chaw ntawm silicon thiab deoxidizer. FeSi 65 feem ntau raug xaiv los ua qhov sib npaug ntawm qhov ntau thiab tus nqi. FeSi 72 thiab FeSi 75 yog siv thaum nws yog ib qho tseem ceeb los txo qhov loj ntawm cov additive rau ib chav tsev ntawm kev qhia Si thiab ua kom kev noj qab haus huv ntau dua. Thaum sib piv cov khoom, nws yog qhov tsim nyog xav txog ntau duatus nqi-per-effective-Si, thiab tsis yog tus nqi ib tuj xwb.
3) Dab tsi yuav tsum tau suav nrog hauv specification (PO)
Nqe Lus Nug 5: Dab tsi yuav tsum tau sau tseg, tshwj tsis yog rau lub hom phiaj.
Teb 5:Txhawm rau kom tsis txhob muaj kev tsis sib haum xeeb thiab tau txais qhov txiaj ntsig tau, lawv feem ntau sau tseg:
- Si (yam tsawg kawg los yog ntau yam) thiab qhov tseem ceeb impurity txwv (feem ntau P / S).
- Fraction: qhov loj loj ntau thiabhloov txwvtxuas mus rau txoj kev (sieve / feem pua hauv qab qhov loj me).
- Kev cim ntau thiab kev taug qab: kom paub tseeb tias COA sib phim cov hnab tshwj xeeb / loj- hnab.
- Sampling puag thiab thov qhov rais.
Nqe Lus Nug 6: Cov ntaub ntawv dab tsi feem ntau thov los ntawm cov neeg xa khoom.
Teb 6:Feem ntau qhov noCOAnrog batch tooj,MSDS, packing list, thiab, yog tias tsim nyog, ib daim ntawv pov thawj - ntawm keeb kwm thiab kev pom zoo ntawm HS- code nyob rau hauv cov ntaub ntawv txhawm rau txo kev pheej hmoo ntawm kev lis kev cai.
Cov lus nug nquag
Nqe Lus Nug: Lub hom phiaj twg ntawm ferrosilicon yog "zoo tshaj".
Teb: Tsis muaj universally zoo tshaj plaws. Qhov kev xaiv nyob ntawm txoj haujlwm thiab tag nrho cov nqi, suav nrog kev poob thiab kev ruaj ntseg.
Nqe Lus Nug: Puas muaj peev xwm hloov FeSi 65 nrog FeSi 75.
Teb: Qee lub sij hawm yog, tab sis koj yuav tsum rov xam cov kev noj, xyuas cov impurities thiab feem ntau thiab paub meej nrog ib pawg kuaj.
Nqe Lus Nug: Vim li cas nws tseem ceeb kom txwv kev hloov pauv?
Teb: Cov nplua oxidize sai dua thiab poob thaum lub sij hawm overloads, txo cov Si zoo thiab nce tus nqi tiag.
Vim li cas thiaj xaiv peb?
- Peb pab tsim cov PO- specification kom lub hom raws li tus cwj pwm tiag tiag: Si, impurities, feem, nplua txwv thiab xeem puag.
- Ntau ruaj khov thiab traceability: Clear labeling and lot-by-lot COA to simplify incoming inspections.
- Export ntim thiab thauj khoom tsim los rau kev thauj mus los ntev kom txo tau kev puas tsuaj thiab kev loj hlob ntawm cov khoom me me hauv kev thauj mus los.
