Ferrosilicon yog ferroalloy ntawm hlau thiab silicon ua nyob rau hauv submerged hluav taws xob arc rauv los ntawm kev txo quartz nrog coke, nrog hlau ntxiv li seem los yog hlau ore. High - qib purity yog siv qhov twg silicon cov ntsiab lus, kev tswj tsis huv thiab kev sib xws tseem ceeb dua li tus nqi. Kab lus no piav qhia txog qib 441 thiab 553, qhia tau hais tias ferrosilicon txawv li cas ntawm cov hlau silicon, tshuaj xyuas cov ntawv thov tseem ceeb, thiab suav nrog cov lus sau hnub tim nqe lus sau tseg rau Lub Xya Hli 14 los pab cov neeg yuav khoom txhais cov lus keeb kwm yav dhau los.
Qib 441 thiab 553 txhais li cas
Hauv kev lag luam thoob ntiaj teb silicon, peb tus lej - tus lej tsim 441 thiab 553 piav qhia txog qhov siab tshaj plaws tso cai cov ntsiab lus ntawm hlau, txhuas thiab calcium hauv cov khoom, qhia hauv qhov hnyav feem pua. Rau qib 441, qhov txwv yog 0.4 feem pua ntawm hlau, 0.4 feem pua ntawm txhuas thiab 0.1 feem pua calcium, uas tawm hauv cov ntsiab lus silicon ntawm 99 feem pua. Rau qib 553, cov kev txwv yog 0.5 feem pua hlau, 0.5 feem pua ntawm txhuas thiab 0.3 feem pua calcium, thiab cov ntsiab lus silicon feem ntau teev ntawm lossis siab dua 98.5 feem pua. Tib lub cim yog siv thoob plaws hauv kev lag luam metallurgical silicon, thiab cov neeg yuav khoom yuav tsum paub meej tias qhov txwv tsis pub muaj nyob rau hauv cov qauv siv hauv lub tebchaws lossis daim ntawv pov thawj zeb, vim tias cov ciam teb tuaj yeem sib txawv me ntsis ntawm cov qauv.
Cov lej yog li piav qhia txog kev tswj tsis huv es tsis yog tus lej silicon ruaj khov. A 441 qib yog nruj dua ntawm calcium thiab me ntsis nruj ntawm cov hlau thiab txhuas ntau dua 553, uas ua rau nws nyiam cov tswv yim rau txhuas -silicon alloys thiab tshuaj siv qhov twg calcium cuam tshuam rau cov txheej txheem.
Ferrosilicon thiab Hlau Silicon: Lawv txawv li cas
Ferrosilicon thiab hlau silicon feem ntau tsis meej pem vim ob leeg yog silicon - cov khoom siv hlau, tab sis lawv txawv ntawm qib silicon thiab lub hom phiaj tsim khoom. Ferrosilicon yog ferroalloy uas nws cov qhab nia raug npe los ntawm cov ntsiab lus silicon, xws li FeSi72 thiab FeSi75, lub ntsiab lus yog cov ntsiab lus ntawm silicon ntawm 72 thiab 75 feem pua. Nws yog tsim nyob rau hauv ntau qhov ntau thiab siv feem ntau yog deoxidizer thiab alloying tus neeg sawv cev hauv steelmaking thiab foundry hlau. Hlau silicon, tseem hu ua industrial silicon, yog ib yam khoom purer nrog silicon cov ntsiab lus siab tshaj 98.5 feem pua, thiab 441 thiab 553 designations feem ntau siv rau pawg no. Hauv cov ntaub ntawv luam tawm ob tsev neeg cov khoom lag luam feem ntau sib xyaw, yog li nws yog ib qho tseem ceeb los xyuas seb qhov kev qhia tshwj xeeb hais txog qib ferrosilicon xws li FeSi75 lossis qib metallurgical silicon xws li 441.
Cov ntawv thov tseem ceeb ntawm High -Purity Ferrosilicon
Steelmaking: silicon tshem tawm oxygen los ntawm cov hlau molten thiab nce lub zog thiab hardenability; qis-aluminium ferrosilicon yog nyiam rau cov qib tshwj xeeb steel.
Foundry: ferrosilicon yog siv los ua ib qho inoculant hauv grey thiab ductile hlau los tswj graphite qauv.
Aluminium alloys: silicon txhim kho casting fluidity thiab txhua yam khoom ntawm aluminium-silicon alloys.
Kev lag luam tshuaj: silicon hlau yog raw khoom rau silicones, fumed silica thiab lwm yam organosilicon khoom.
Hnub ci thiab hluav taws xob: siab- purity silicon yog ntxiv refined rau photovoltaic thiab semiconductor daim ntaub ntawv.
Nqe Reference Snapshot: Lub Xya hli ntuj 14
Cov lus hauv qab no tau kaw rau Lub Xya Hli 14 raws li ib zaug - hnub siv snapshot. Lawv yog cov keeb kwm hais txog qib, tsis yog tam sim no muab, thiab cov nqi hloov pauv tiag tiag nyob ntawm qhov ntau, cov nqe lus xa khoom, cov nyiaj them poob haujlwm thiab qhov zoo.
Export ferrosilicon siv tus nqi, USD ib metric tuj:
| Khoom | Qib | Nqe lus | Hauv paus |
|---|---|---|---|
| Ferrosilicon | 72 | 1000-1030 | FOB Tianjin Chaw nres nkoj |
| Ferrosilicon | 75 | 1080-1100 | FOB Tianjin Chaw nres nkoj |
Hauv tsev qis- txhuas ferrosilicon siv tus nqi, yuan ib metric ton, ntuj thaiv, ex- Hoobkas nqi nyiaj ntsuab suav nrog se:
| Specification | Thaj tsam | Nqe |
|---|---|---|
| Si75 Al qis dua 0.1 feem pua | Qinghai | 6700-6750 |
| Si75 Al qis dua 0.5 feem pua | Qinghai | 6400-6450 |
| Si75 Al qis dua 0.1 feem pua | Sab hauv Mongolia | 6700-6750 |
| Si75 Al qis dua 0.5 feem pua | Sab hauv Mongolia | 6400-6450 |
Cov lus xa tawm qhia txog tus nqi ntawm FeSi75 tshaj FeSi72, uas qhia txog cov ntsiab lus ntawm silicon siab dua thiab cov neeg yuav khoom nruj dua rau qib 75. Cov lus hauv tsev qhia tau hais tias tus nqi them rau qis dua -aluminium variant, vim tias cov ntsiab lus aluminium tsawg muaj nuj nqis hauv qib siab - qib steel ntau lawm.
Dab tsi txav Ferrosilicon Nqe
Ntau yam tsav ferrosilicon tus nqi txav. Hluav taws xob yog tus nqi tsim khoom loj tshaj plaws, yog li cov nqi hluav taws xob hauv cheeb tsam thiab cov dej muaj hluav taws xob ncaj qha cuam tshuam rau cov khoom siv. Quartz, coke thiab hlau input nqi teev cov raw- cov khoom siv hauv pem teb. Kev thov xa tawm los ntawm cov neeg tsim khoom hlau nyob rau sab hnub tuaj Asia, Nyiv, Kaus Lim Kauslim thiab Europe absorbs cov khoom seem ntawm Suav peev, thiab cov nqi thauj khoom ntawm cov chaw nres nkoj xws li Tianjin ntxiv rau tus nqi xa khoom. Cov nqi pauv kuj tseem ceeb vim tias feem ntau cov ntawv cog lus xa tawm tau txiav txim siab hauv USD. Thaum kawg, kev txwv ib puag ncig thiab kev tsim khoom hauv cov tuam txhab tsim khoom tseem ceeb tuaj yeem ua kom nruj cov khoom lag luam sai thiab thawb tus nqi.
Cov lus nug nquag
Dab tsi yog qhov txawv ntawm ferrosilicon 441 thiab 553?Cov lej piav qhia qhov siab tshaj plaws hlau, txhuas thiab calcium cov ntsiab lus. Qib 441 tso cai rau 0.4 feem pua hlau, 0.4 feem pua aluminium thiab 0.1 feem pua calcium, thaum qib 553 tso cai 0.5 feem pua hlau, 0.5 feem pua aluminium thiab 0.3 feem pua calcium. Cov qib 441 yog li ntawd muaj cov ntsiab lus silicon ntau dua thiab nruj dua impurity tswj.
Puas yog ferrosilicon zoo ib yam li hlau silicon?Tsis yog Ferrosilicon qib xws li FeSi72 thiab FeSi75 muaj 72 mus rau 80 feem pua silicon, thaum hlau silicon muaj 98.5 feem pua los yog ntau dua. Ob qho tib si los ntawm hluav taws xob qhov cub txo qis ntawm quartz, tab sis lawv ua haujlwm sib txawv thiab raug pauv raws li cov khoom sib cais.
Dab tsi yog ferrosilicon siv rau hauv steelmaking?Ferrosilicon yog tus qauv deoxidizer rau molten steel thiab tus neeg sawv cev alloying uas nce lub zog thiab hardenability. Tsawg- qib aluminium yog siv thaum cov khoom siv txhuas yuav tsum tau txo qis hauv cov hlau tshwj xeeb.
Vim li cas qis - txhuas ferrosilicon nqi ntau dua?Aluminium qis dua yuav tsum tswj cov txheej txheem nruj dua thiab qee zaum cov khoom siv tshwj xeeb lossis cov kauj ruam ua kom zoo. Tus nqi sib txawv pom meej meej nyob rau hauv cov lus siv hauv tsev, qhov tsawg - aluminium variant yog hais txog kwv yees li 250 txog 300 yuan ib tuj siab tshaj tus qauv qib.
Yuav ua li cas tus neeg yuav khoom qhia ferrosilicon?kev yuav khoom tshwj xeeb yuav tsum hais txog cov khoom lag luam, qib, qib silicon, qhov siab tshaj plaws hlau, txhuas thiab calcium cov ntsiab lus, qhov loj me, cov txheej txheem ntim khoom thiab cov qauv siv, kom daim ntawv pov thawj zeb tuaj yeem kuaj xyuas qhov kev txiav txim.
