FerrosiliconThiab ferromanganese yog ob qho tseem ceeb ferroalloys, feem ntau txawv hauv lawv cov ntsiab lus tseem ceeb. Thiaj li, lawv nthuav tawm cov kev sib txawv tseem ceeb hauv smelting txheej, cov ntawv thov, muaj pes tsawg leeg, thiab cov khoom siv lub cev.
1. Tub ntxhais sib txawv sib txawv
Qhov tseem ceeb ntawm cov lus dag nyob hauv lawv cov ntsiab lus tseem ceeb.
- Ferrosilicon:Feem ntau tsim ntawm cov hlau thiab silicon, nrog silicon cov ntsiab lus feem ntau xws li 15% mus rau 90%. Nws tau cais los ntawm Silicon cov ntsiab lus rau hauv qis {3} {{} {{{{{{{{{{{{{{
- Ferromanganese: Its primary components are iron and manganese, with manganese content generally ranging from 60% to 80%. Based on carbon content, it is further subdivided into high-carbon ferromanganese (carbon >7%), Nruab Nrab {{- carbon ferromanganese (1.0%- 1.5%), thiab cov pa roj carbon ferromanganese (<0.7%).
2. Qhov sib txawv hauv cov ntawv thov smelting
Cov ntawv thov tseem ceeb ntawm ferro - silicon
Deagidizing: Thaum Statmaking, silicon reacts nrog oxygen nyob rau hauv molten steel los ua silicon dioxide (sitio₂), uas raug ntiab tawm li slag. Qhov no txo cov ntsiab lus pa oxygen hauv cov hlau thiab txhim kho nws qhov zoo.
Nodularizer: Ntxiv ferrosilicon thaum cam khwb cia hlau ntau lawm txhim kho crystalline qauv, txo dawb cam khwb cia hlau, thiab txhim kho kev nruj thiab muaj zog.
Alloying Tus Neeg Sawv Cev: Siv hauv kev tsim cov neeg tshwj xeeb xws li cov hlau uas silicon thiab lub caij nplooj ntoo hlav kom txhim kho preathability, elasticity, thiab lwm yam khoom.
Cov ntawv thov tseem ceeb ntawm ferromanganese
Desulfurizer thiab deoxidizer: manganese reacts nrog leej faj hauv Molten Steel los tsim mance sulfide (mns) thaum ib txhij) lub thawv hlau. Qhov kev ua no dual kev no txo qhov brittleness thiab txhim kho cov haujlwm kub.
Kev sib dhos thiab cov khoom siv dag zog rau tus neeg saib xyuas: raws li cov khoom siv tseem ceeb rau manganese steel ntau lawm, manganese txhim kho cov tawv hlau, hnav tsis kam, thiab lub zog. Nws yog feem ntau siv nyob rau hauv kev tsim khoom siv machinery, ntsia, thiab hnav - cov khoom siv tiv taus.
3. Qhov sib txawv hauv lub cev thiab tshuaj
| Qhov Ntev | Ferrosilicon | Ferromanganese |
|---|---|---|
| Kev tshwm sim | Feem ntau cov nyiaj - grey} grey grey grey grey grey auster ntawm tus ntoo khaub lig- seem | Feem ntau yog tsaus grey lossis xim av qog nrog cov ntoo khaub lig ntxhib - seem |
| Ceev | Txo qis nrog nce cov ntsiab lus silicon, kwv yees li 2.5 - 4.7 g /m³ | Siab dua, kwv yees 6.8 - 7.3 g /m³ |
| Melting point | Cov ntsiab lus ntau silicon ua rau muaj txiaj ntsig zoo melting taw tes, kwv yees 1100 - 1300 degree | Melting taw tes yog kwv yees li 1200 - 1350 degree, nrog kev hloov me me nyob ntawm cov ntsiab lus carbon |
| Tshuaj Lom Zem | Silicon yooj yim rau oxidize thiab tuaj yeem hnov mob nrog oxygen, nitrogen, etc. ntawm qhov kub | Manganese yooj yim rov qab nrog cov leej faj thiab oxygen, thiab muaj kev tsis zoo corrosion tsis kam |
