Hom QC Workflow rau FeSi70

Qauv- nqa cov khoom sawv cev los ntawm ntau qhov crushed.

Kev npaj- rau ICP: acid digestion; rau XRF: xovxwm hmoov pellet lossis fusion hlaws.

Kev tsom xam- khiav thawj txoj kev (ICP-OESrau qhov tseeb;XRFrau kev kuaj ceev).

Hla -kos- periodically xyuas nroggravimetrictxoj kev rau daim ntawv pov thawj.

Qhia- sib pivqib spec(xws li Si 68–72 %, Al Tsawg dua lossis sib npaug li 2 %) thiab muab Daim Ntawv Pov Thawj Kev Ntsuam Xyuas (CoA).

Nco tseg: TitrationTsis tshua muaj siv ncaj qha rau Si hauv FeSi70 vim Si tsis yooj yim titrated hauv lub xeev hlau; nws ntsuas tsis ncaj (los ntawm qhov sib txawv tom qab txiav txim siab Fe thiab lwm yam) los yog ntawm SiO₂ gravimetry.

Dab tsi yog FeSi70 Nqe Ib Tuj hauv 2024 / Nqe Zoo Tshaj FeSi72/75?

2024 Tus Nqi Ua Lag Luam thiab Kev Ntsuas Tus Nqi Sib Piv

Tus nqi rau FeSi70, FeSi72, thiab FeSi75 txawv ntawmcheeb tsam, tus neeg muag khoom, xaj loj, Si cov ntsiab lus, thiabraw khoom / nqi zog. Raws li ntawmnruab nrab-2024, cov nqi lag luam raug yog:

2024 Nqe Ranges (USD / Metric Ton, FOB chaw nres nkoj loj)

Khoom	Si Content	Hom Nqe Ntau Yam	Lus hais
FeSi 70	68–72 %	1,000–1,250	Lower Si → qis raw khoom & nqi zog, pheej yig tshaj ib tuj
FeSi72	70–74 %	1,050–1,300	Si siab dua me ntsis, tus nqi qis nce
FeSi 75	72–78 %	1,150–1,400	Siab tshaj Si → muaj nuj nqis ntau dua tab sis kim dua ib tuj

Nqe Advantage ntawm FeSi70

$50–150/ton pheej yig duatshaj FeSi72.

$150–200/ton pheej yig duatshaj FeSi75 hauv ntau lub khw.

Qhov sib txawv qhia txog:

Tsawg silicon ore noj ib tuj ntawm alloy.

Txo kev siv hluav taws xob (tsawg Si yuav tsum tau txo).

Kev lag luam qis qis rau nruab nrab-Si ferroalloy hauv kev siv ntau.

Kev txiav txim siab txog nqi

Ib chav tsev ntawm Si ntxiv: FeSi72/75 tuaj yeem siv nyiaj ntau dua thaum xav tau siab Si ntxiv, vim tias yuav tsum muaj tsawg dua alloy loj.

Rau qis / nruab nrab Si lub hom phiaj(piv txwv li, 0.15-0.30% Si hauv steel): FeSi70 muabqis tag nrho cov nqi alloyvim tus nqi pheej yig dua.

Cov neeg muag khoom me metau txais txiaj ntsig los ntawm FeSi70 tus nqi qis tonnage thiab nthuav dav.

Cov xwm txheej cuam tshuam rau 2024 Nqe

Silicon ore (quartz) nqi- Kev thov thoob ntiaj teb los ntawm hnub ci / hluav taws xob cuam tshuam rau txhua qib.

Cov nqi hluav taws xob- EAF tus nqi tseem ceeb; spikes nce tag nrho cov nqi ferroalloy.

Supply-demand balance- muaj zog steel ntau lawm boosts ferroalloy thov.

Logistics & ntshuam lub luag haujlwm- cuam tshuam tus nqi xa khoom sib txawv los ntawm cheeb tsam.

Order ntim – bulk buyers (>20 t) sib tham nrog tus nqi qis dua.
