Tus lej 75, 72 thiab 65 txhais li cas
Ferrosilicon yog hlau-silicon alloy siv feem ntau ntxiv silicon rau hlau thiab khi oxygen thaum deoxidation. Nws cov kev faib ua lag luam yog tsim los ntawm ib tus lej: cov ntsiab lus silicon. Lub npe xws li FeSi75 hais tias cov hlau yog muab los ntawm 75% silicon hauv paus, FeSi72 ntawm 72% hauv paus thiab FeSi65 ntawm 65%. Txhua yam hauv qhov tshwj xeeb - carbon, sulfur, phosphorus, aluminium thiab loj - yog sau raws li qhov txwv uas zaum saum lub hauv paus silicon.
Qhov ua tau zoo yog tias cov ntsiab lus silicon thiab cov seem seem txav mus ua ke. Kev tsim cov qib siab -silicon alloy yuav tsum tau ua kom huv, txo cov txheej txheem kub, uas tseem ua rau cov pa roj carbon, sulfur thiab phosphorus tawm ntawm cov hlau. Lub hauv paus qis silicon tau mus txog nrog lub zog txo qis, thiab cov khoom seem uas tsis tau txo qis nyob hauv cov hlau. Tias yog vim li cas FeSi75 qhia lub qhov rais nruj tshaj plaws, FeSi72 zaum hauv nruab nrab, thiab FeSi65 nqa qhov dav tshaj plaws.
Cov ntsiab lus ntawm Silicon thiab Residual txwv
| Lub npe | Cov ntsiab lus (%) | C (max, %) | S (max, %) | P (max, %) | Al xaiv (max, %) |
|---|---|---|---|---|---|
| FeSi75 | 74.0-80.0 | 0.10 | 0.02 | 0.035 | 2.0 / 1.5 / 1.0 / 0.5 / 0.1 |
| FeSi72 | 72.0-80.0 | 0.15 | 0.02 | 0.04 | 2.0 / 1.5 |
| FeSi65 | 65.0-72.0 | 0.20 | 0.03 | 0.04 | 2.0 |
Cov duab saum toj no yog cov kab lus ib txwm hais hauv kev lag luam xa tawm thiab sau rau ntawm kev xa tawm - qhov hnyav. Aluminium yog cov khoom uas tsim cov qib sub- feem ntau hauv 75 tsev neeg: qis-aluminium FeSi75 nrog 0.5% lossis 0.1% aluminium qab nthab yog cov khoom sib txawv los ntawm qhov dav dav -lub hom phiaj 2.0% aluminium qib, thiab qhov nruj tshaj plaws txhuas txwv yog tshwj tseg rau cov hluav taws xob 10% sib sib zog nqus steel, qhov sib sib zog nqus welding steel 10. residues hloov qhov kev ntxhib los mos los yog tus cwj pwm arc ntawm qhov tso nyiaj.
FeSi75 hauv Kev nthuav dav
FeSi75 yog qib siv rau siab -lub luag haujlwm deoxidation thiab rau silicon ntxiv rau siab -silicon steels. Nws ua ke ntawm 74.0% cov ntsiab lus ntawm silicon yam tsawg kawg nkaus nrog cov pa roj carbon tsawg, leej faj thiab phosphorus ua rau nws haum qhov twg cov hlau tsis tuaj yeem zam cov khoom seem. Cov kev siv feem ntau yog cov hlau hluav taws xob, lub caij nplooj ntoos hlav steel, stainless melting xyaum, foundry inoculants thiab zus tau tej cov silicon- bearing master alloys. Vim tias qhov txo qis yog tsav mus ntxiv, kev siv hluav taws xob ib tonne thiab qhov kev thov ntawm qhov txo qis yog ob qho tib si siab dua rau qib qis, thiab tus nqi ntawd qhia ncaj qha rau ntawm tus nqi muag.
FeSi72 thiab FeSi65 hauv Kev nthuav dav
FSI 72:ib nrab- qib qeb nyob nruab nrab ntawm qib siab -purity 75 tsev neeg thiab qib 65. Nws raug xaiv qhov twg qhov dav me ntsis carbon, sulfur thiab phosphorus qhov rais tau txais thiab qhov twg tus neeg yuav khoom xav tau tus nqi qis dua ib chav tsev ntawm silicon, tab sis tseem xav tau kev ua haujlwm ntawm silicon ntau dua li qib 65. Lub luag haujlwm feem ntau yog cov pa roj carbon monoxide thiab qis - alloy steel deoxidation thiab kev ua haujlwm hauv qhov chaw tsim khoom.
FSI 65:qhov dav - qib hom phiaj nrog lub qhov rais loj tshaj qhov seem seem thiab tus nqi qis tshaj plaws. Nws yog siv rau deoxidation ntawm carbon steels ntau, ua silicon carrier nyob rau hauv casting xyaum thiab raws li feedstock rau silicon - bearing briquettes thiab blends qhov twg cov residual specification yog teem los ntawm downstream txheej txheem es tsis yog los ntawm cov hlau nws tus kheej.
Loj Fraction thiab Packing
Kev faib tawm tsis yog tshuaj lom neeg xwb. Qhov loj me txiav txim siab yuav ua li cas cov hlau coj tus cwj pwm hauv lub ladle: cov pob coarse dissolves maj mam thiab tuaj yeem zaum ntawm lub slag yog tias da dej txias, thaum cov khoom zoo dissolves sai tab sis nws yuav poob rau hauv cov roj kwj thiab cov plua plav tsim thaum tuav.
10-100 hli:tus qauv export feem rau qhov cub thiab ladle ntxiv.
10-50mm thiab 3-10mm:siv qhov chaw ntxiv, xws li lub tshuab xaim lossis lub bunker, tsis tuaj yeem tuav cov pob loj loj.
0-3 hli nplua thiab milled hmoov:siv hauv briquettes, vuam electrode coatings, hnyav-media ncua kev kawm ntawv thiab hmoov- metallurgy blends.
Packing ua raws tib lub logic. Ib -tonne jumbo hnab nrog ib lub liner yog tus qauv rau cov thawv xa khoom, 25 kg hnab haum rau cov neeg siv khoom me me thiab rov ua haujlwm dua, thiab cov nruas steel lossis lub tshuab nqus tsev yog siv thaum tus neeg yuav khoom xav kom tshem tawm cov khoom ntub dej thaum lub sijhawm taug kev hauv hiav txwv ntev.
Yuav Xaiv Cov Qib Zoo Li Cas
Pib los ntawm cov lus qhia steel thiab txheeb xyuas cov khoom seem uas tau txwv cov txheej txheem.
Yog tias cov pa roj carbon, sulfur lossis phosphorus tswj nruj, yuav FeSi75 thiab tom qab ntawd xaiv cov aluminium sub- qib uas haum rau kev ua kom yaj.
Yog tias qhov seem seem qhib, FeSi65 lossis FeSi72 muab tib lub silicon rov qab ntawm tus nqi qis dua.
Sib piv cov feem me me rau txoj kev sib ntxiv es tsis yog ua rau tus cwj pwm, vim tias kev poob qis feem ntau raug nqi ntau dua li tus nqi sib txawv ntawm ob qhov me me.
Yuav tsum tau daim ntawv pov thawj zeb soj ntsuam rau cov khoom xa tuaj thiab xyuas kom meej tias cov silicon hauv paus thiab cov kev txwv seem tau teev tseg rau tib tus qauv thiab cov qauv kev sim.
Cov lus nug nquag
Q: Puas yog FeSi75 tsuas yog ib qho purer version ntawm FeSi65?
Hauv cov nyhuv, yog. Ob leeg yog hlau-silicon alloys, thiab qhov sib txawv yog lub hauv paus silicon thiab lub qhov rais seem uas tuaj nrog nws. FeSi75 yog tsim nrog kev txo qis, yog li carbon, sulfur thiab phosphorus qis dua; FeSi65 yog tsim los nrog txo qis zog thiab yog li nqa ib qho kev nthuav dav ntxiv.
Q: Vim li cas cov aluminium sub- qib tseem ceeb yog tias silicon yog tus lej tseem ceeb?
Aluminium yog qhov seem uas feem ntau txwv tsis pub qib ferrosilicon rau cov ntawv thov tseem ceeb. Hluav taws xob cov hlau thiab sib sib zog nqus- cov qib kos duab qhia qis aluminium kom tsis txhob muaj kev puas tsuaj rau cov khoom sib nqus los yog kev ua tus cwj pwm, thiab cov khoom siv vuam txwv tsis pub nws tswj xyuas qhov tso nyiaj, yog li tib lub hauv paus silicon tuaj yeem faib ua ntau yam khoom sib txawv.
Q: Qib twg yuav tsum siv lub tshuab steel rau deoxidation?
Rau cov pa roj carbon monoxide thiab qis - alloy steel qhov dav dav - lub hom phiaj FeSi65 lossis FeSi72 ib txwm muaj txaus, vim tias deoxidation tsuas yog xav tau silicon los khi oxygen thiab cov ntsiab lus seem ntawm cov hlau yog xoob. Qhov twg qib steel txwv cov pa roj carbon, sulfur lossis phosphorus, FeSi75 yuav tsum tau ua kom deoxidation tsis rov tsim cov ntsiab lus.
Q: Ntau npaum li cas ferrosilicon feem ntau ntxiv rau lub tshav kub ntawm cov hlau?
Ntxiv yog nyob ntawm cov ntsiab lus oxygen ntawm da dej thiab lub hom phiaj silicon qib hauv cov hlau tiav, yog li nws raug xam los ntawm ib lub tshav kub es tsis kho. Tus nqi rov qab kuj tseem ceeb: cov pob zeb ntxhib ntxiv thaum ntxov hauv cov kais dej rov qab tsawg dua silicon dua li cov khoom siv me me ntxiv raws li kev tswj hwm, uas yog vim li cas kev qhuab ntuas txo kev noj.
Q: Puas yog ferrosilicon nqus dej noo thaum xa khoom?
Cov hmoov nplej thiab cov seem zoo tuaj yeem khaws cov dej noo los ntawm huab cua ntub, uas tsim teeb meem kev tuav thiab kev nyab xeeb thaum them nyiaj. Rau kev caij nkoj ntev ntev cov lus teb ib txwm yog polyethylene liner hauv lub hnab jumbo, lossis lub nruas ntim rau cov feem zoo tshaj plaws, thiab cov phiaj xwm xa khoom uas tsis txhob qhib lub sijhawm ntev - huab cua cia ntawm qhov chaw nres nkoj ntub.
Q: Cov ntaub ntawv dab tsi yuav tsum nrog rau kev xa khoom ferrosilicon?
Daim ntawv tshaj tawm kev lag luam, daim ntawv teev npe, daim nqi ntawm daim ntawv pov thawj, daim ntawv pov thawj ntawm keeb kwm thiab daim ntawv pov thawj zeb tsom xam suav nrog silicon, aluminium, carbon, sulfur thiab phosphorus yog cov txheej txheem ib txwm muaj. Daim ntawv pov thawj kev soj ntsuam yuav tsum muaj feem cuam tshuam rau qhov tseeb ntawm cov cua sov los yog ntau cov khoom xa tuaj, thiab cov feem me me thiab cov ntim khoom yuav tsum tau hais tib yam hauv daim ntawv cog lus thiab cov ntaub ntawv xa khoom.
