Kev txhais thiab hom thawj
Ferromanganeseyog ib qho hlau alloy uas tsim los ntawm manganese, hlau, thiab kab kawm xws li carbon thiab silicon. Nws tsis yog ib qho khoom lag luam tab sis ib tsev neeg ntawm cov alloys feem ntau cais los ntawm cov ntsiab lus carbon kom tau raws li kev lag luam sib txawv.
- Siab -carbon ferromanganese: Feem ntau muaj ntau dua 2% carbon, qhov no yog hom kev siv ntau tshaj plaws thiab kev lag luam hauv kev tsim khoom. Nws yog dav siv rau deoxidation thiab alloying hauv cov qib steel qib.
- Nruab nrab-carbon ferromanganese: Nrog cov ntsiab lus carbon xws li 0.7% txog 2.0%, nws yog siv rau qib steel uas xav tau cov pa roj carbon tshwj xeeb.
- Tsawg-carbon ferromanganese: Nrog cov ntsiab lus carbon qis dua 0.7%, feem ntau yog siv rau hauv kev tsim cov khoom siab -kawg zoo li siab - alloy steels thiab tshwj xeeb steels. Vim nws cov txheej txheem ntau lawm, nws cov nqi kuj yog siab dua.
- Silicomanganese alloy: Muaj silicon tseem ceeb ntxiv rau manganese thiab hlau. Nws ua ke deoxidation thiab alloying ua haujlwm, muab kev ua haujlwm siab dua thiab ua haujlwm ua lwm yam tseem ceeb ferroalloy hauv steelmaking.
Kev tshuaj xyuas ntawm Peb Lub Luag Haujlwm ntawm Silicon Manganese
Ferromanganese plays ntau lub luag haujlwm tseem ceeb hauv kev tsim cov hlau, nrog rau nws daim ntawv thov ncaj qha txiav txim siab qhov kawg thiab cov khoom ntawm cov hlau.
1. Muaj zog Deoxidation thiab Desulfurization
- Deoxidizer: Thaum kawg ntawm cov txheej txheem steelmaking, cov pa ntau dhau hauv cov hlau molten hnyav ua rau nws lub zog thiab lub zog. Manganese nthuav tawm muaj zog affinity rau oxygen. Raws li cov deoxidizer zoo, nws reacts nyiam nrog oxygen los tsim manganese oxides uas tsiv mus rau hauv cov slag, yog li purifying cov hlau molten.
- Desulfurization: Sulfur yog thawj qhov ua rau cov hlau "kub luv luv." Manganese reacts nrog sulfur los tsim manganese sulfide, uas muaj qhov siab melting point thiab stability. Qhov no zoo mitigates sulfur cov teebmeem thiab ua kom cov hlau ua haujlwm kub.
2. Ntsiab Alloying Element
Manganese yog qhov tseem ceeb tshaj plaws thiab kev lag luam alloying hauv cov hlau. Ntxiv ferromanganese precisely qhia manganese rau hauv hlau, yog li:
- Txhim khu lub zog, hardness, thiab hnav tsis kam.
- Txhim kho toughness thiab tshem tawm sulfur -induced brittleness.
- Txhim kho steel hardenability.
- Yog li ntawd, yuav luag tag nrho cov qib steel -los ntawm cov rebar zoo tib yam rau siab - lub zog tsheb daim ntawv thiab hnav- rails resistant - yuav tsum tau ferromanganese ntxiv rau alloying.
3. Txhim kho Casting Properties
Nyob rau hauv cam khwb cia hlau ntau lawm, ferromanganese stabilizes thiab refines graphite qauv, kev txhim kho casting mechanical zog rau ntau zog thiab kev ua tau zoo sib xws.
Synergistic Effects of Iron-Manganese nrog rau lwm yam khoom siv hlau
Hauv cov txheej txheem metallurgical,hlau manganesefeem ntau siv synergistically nrog rau lwm yam ntaub ntawv. Piv txwv li, nyob rau hauv ladle refining los yog ductile hlau ntau lawm, cov ntaub ntawv xws li silicomanganese alloy, ferromanganese, thiab silicon slag nodularizing cov neeg ua hauj lwm yuav tsum tau ua hauj lwm nyob rau hauv ua ke kom ua tiav ntau complex metallurgical lub hom phiaj thiab pab kom meej tswj cov khoom steel.
Hauv cov ntsiab lus, lo lus teb rau dab tsi hlau -manganese yog siv rau permeates tag nrho cov niaj hnub metallurgical kev lag luam. Nws ua hauj lwm tsis tau tsuas yog raws li "cov pob txha" rau kev txhim kho steel zog tab sis kuj yog "tus neeg saib xyuas" rau purifying steel zoo. Los ntawm macro- nplai cov qauv zoo li txuas hniav mus rau micro- nplai cov khoom hauv tsheb, tus nqi ntawm cov hlau-manganese alloys yog nyob txhua qhov chaw. Tau txais kev nkag siab tob txog nws txoj haujlwm thiab kev ua lag luam kev lag luam tuav qhov tseem ceeb ntawm kev lag luam rau txhua lub lag luam hauv kev lag luam steel.
