Ferrosilicon, feem ntau hu ua "vitamin" ntawm kev lag luam hlau, pib nws txoj kev taug kev nrog cov qauv tseeb thiab siab - kub smelting ntawm ntau yam khoom siv raw. Nkag siab txog nws cov khoom siv raw khoom yog thawj kauj ruam kom nkag siab txog cov txiaj ntsig ntawm qhov tseem ceeb ferroalloy. Kab lus no tau txheeb xyuas cov ntaub ntawv tseem ceeb thiab kev tsim khoom ntawm ferrosilicon, thiab piav qhia txog kev ua kom pom tseeb thiab kev coj ua ntawm Henan Fengyang Metallurgical Materials Co., Ltd.
I. Core Raw Materials: Trinity of Components
Ferrosilicon yog ib qho tseem ceeb ntawm silicon (Si) thiab hlau (Fe). Nws txoj kev tsim khoom lag luam tsis ncaj qha ua ke ob cov hlau no, tab sis tau txais lawv hauv ib kauj ruam dhau los ntawm kev ua haujlwm siab -kub tshuaj txo cov txheej txheem. Cov khoom siv raw yooj yim feem ntau suav nrog peb pawg hauv qab no:
Silicon Source: Quartz (Silica)
Qhov no yog cov khoom siv tseem ceeb uas muab cov khoom siv silicon, feem ntau yog quartz lossis silica. Nws cov khoom tseem ceeb yog silicon dioxide (SiO₂). Cov kev xav tau zoo rau silica yog nruj: cov ntsiab lus SiO₂ feem ntau yuav tsum siab dua 96%, thiab siab dua 98% rau kev tsim cov siab -silicon ferrosilicon. Nyob rau tib lub sijhawm, kev tswj hwm impurity yog qhov tseem ceeb, tshwj xeeb tshaj yog khaws cov phosphorus (P) thiab aluminium (Al) cov ntsiab lus kom tsawg li sai tau los xyuas kom meej qhov purity ntawm cov hlau kawg.
Reductant: Coke
Nyob rau hauv submerged arc furnaces ncav cuag kub ntawm 1500-1800 degrees Celsius, coke ua raws li tus reductant, lub luag hauj lwm rau txo cov silicon los ntawm silica. Metallurgical coke yog ib qho kev xaiv. Nws lub luag haujlwm yog muab cov pa roj carbon (C) rau cov tshuaj tiv thaiv thaum tseem ua haujlwm ua tus neeg xyuas pib thiab txhawb nqa lub nra hnyav.
Hlau qhov chaw: Hlau Scrap / Mill Scale
Cov khoom siv hlau los yog hlau oxide nplai tsim thaum lub sij hawm dov steel (mill scale) ua lub hauv paus ntawm cov hlau. Lawv feem ntau ua haujlwm ua "regulators" thaum smelting, kho cov hlau - mus rau - silicon piv nyob rau hauv cov hlau los tsim cov qib sib txawv (xws li FeSi75, FeSi65) ntawm ferrosilicon. Ntxiv rau cov ntaub ntawv tseem ceeb no, electrode paste yog siv los ua cov khoom siv hluav taws xob, thiab siv hluav taws xob ntau heev.
Raws li kev lag luam cov ntaub ntawv, kwv yees cov khoom siv raw thiab lub zog siv rau kev tsim ib tuj ntawm tus qauv ferrosilicon (siv FeSi75 ua piv txwv) yog raws li hauv qab no:
| Khoom siv / Zog | Kwv yees kev siv |
|---|---|
| Silica | 1780 - 1850 kg |
| Coke | 890 - 930 kg |
| Hlau Scrap | 220 - 230 kg |
| Electrode Paste | 45 - 55 kg |
| Hluav Taws Xob | 8400 - 9000 kWh |
II. Xav Tau Ntau Lawm: Los ntawm Raw Materials mus rau Alloy
Ferrosilicon feem ntau yog tsim nyob rau hauv loj submerged arc furnaces ntawm cov txheej txheem slagless. Qhov no imposes tsis tshua muaj kev xav tau ntawm kev huv ntawm cov ntaub ntawv raw, uas yuav tsum tsis txhob muaj kab mob xws li av. Thaum kub kub, cov pa roj carbon hauv coke txo cov silicon dioxide hauv silica, tsim cov silicon molten, uas ib txhij fuses nrog cov hlau ntxiv los tsim ferrosilicon alloy.
Cov txheej txheem no muaj zog heev- siv zog, ua hluav taws xob raug nqi ib qho tseem ceeb txiav txim qhov chaw thiab kev sib tw ntawm ferrosilicon ntau lawm. Nyob rau hauv xyoo tas los no, txhawm rau txhim kho ib puag ncig cov qauv, ntau lub tuam txhab tau hloov kho los ntawm cov chaw qhib qhov rooj mus rau "tsawg hood" lossis "semi-kaw" furnaces nruab nrog cov plua plav tshem tawm thiab cov cua sov rov qab.
III. Daim ntawv thov sib txawv: Ib qho Indispensable Industrial Additive
Precisely vim yog cov khoom ntawm silicon thiab hlau, ferrosilicon plays lub luag haujlwm tseem ceeb hauv ntau qhov kev lag luam:
- Steelmaking Deoxidation thiab Alloying: Raws li cov deoxidizer zoo, ferrosilicon tshem tawm cov pa oxygen los ntawm cov hlau molten, txhim kho steel zoo. Nws tseem yog ib qho tseem ceeb ntawm cov khoom siv ntxiv rau kev tsim ntau yam tshwj xeeb steels xws li caij nplooj ntoos hlav steel, bearing steel, thiab hluav taws xob silicon steel.
- Foundry Inoculant: Hauv kev lag luam cam khwb cia hlau, ferrosilicon txhawb nqa graphite nag lossis daus thiab spheroidization, txhim kho cov khoom siv ntawm cov hlau cam khwb cia.
- Lwm Cov Khoom Siv Hluav Taws Xob thiab Cov Khoom Siv: Siab-silicon ferrosilicon tuaj yeem ua tus neeg sawv cev txo qis hauv kev tsim khoom ntawm lwm cov ferroalloys; atomized los yog hauv av ferrosilicon hmoov pom cov ntawv thov hauv vuam electrode manufacturing thiab ua ib qho hnyav nruab nrab hauv kev ua ntxhia.
IV. Kev sib txuas thiab ua kom pom tseeb ntawm Henan Fengyang Metallurgy
