High Carbon Ferro Manganese
Ferromanganese yog ferroalloy nrog cov ntsiab lus siab manganese (high-carbon ferromanganese tuaj yeem muaj ntau npaum li 80 feem pua Mn los ntawm qhov hnyav). lub tshuab hluav taws xob tawg lossis hluav taws xob arc rauv hom, hu ua submerged arc furnace. Cov oxides raug txo qis hauv cov cua sov, ua cov ferromanganese. Ferromanganese yog siv los ua deoxidizer rau hlau.
Lub North American tus qauv specification yog ASTM A99. Kaum qib uas muaj nyob rau hauv cov lus qhia no suav nrog;
Standard ferromanganese
Nruab nrab-carbon ferromanganese
Tsawg-carbon ferromanganese
Ib yam khoom zoo sib xwsyog npua hlau nrog cov ntsiab lus siab ntawm manganese, hu ua spiegeleisen, lossis specular npua hlau.
Kev tsim khoom ntawm Ferromanganese:
Ferromanganese yog tsim los ntawm kev txo qis carbothermal, qhov sib xyaw ntawm manganese dioxide (MnO2) thiab hlau oxide (Fe2O3) yog rhuab nrog cov pa roj carbon zoo li cov thee thiab coke.
Cov tshuaj tiv thaiv tshwm sim nyob rau hauv lub qhov cub tawg los yog lub qhov cub submerged arc, uas ua rau tsim cov ferromanganese.
Cov ntsiab lus ntawm manganese hauv ferromanganese tuaj yeem sib txawv, nrog cov pa roj carbon ntau ferromanganese muaj txog li 80 feem pua manganese los ntawm qhov hnyav.
Daim ntawv thov hauv Steel Kev Lag Luam:
Ferromanganese feem ntau yog siv los ua deoxidizer hauv cov txheej txheem steel, pab tshem tawm impurities thiab txhim kho steel zoo.
Nws ua raws li tus neeg sawv cev alloying, pab txhawb rau cov khoom xav tau ntawm cov hlau xws li nce lub zog, hardness, thiab tsis kam hnav thiab corrosion.
Cov qib sib txawv ntawm ferromanganese (tus qauv, nruab nrab-carbon, thiab qis-carbon) ua rau cov khoom siv hlau tshwj xeeb thiab cov kev xav tau ntawm kev lag luam.
ASTM A99 Txuj Specification:
ASTM A99 yog ib qho dav ua raws North American tus qauv specification uas qhia txog ntau qib ntawm ferromanganese muaj rau kev lag luam siv.
Kaum qib uas tau teev tseg raws li qhov tshwj xeeb no suav nrog tus qauv ferromanganese, nruab nrab-carbon ferromanganese, thiab qis-carbon ferromanganese, thiab lwm yam.
Cov qauv no ua kom muaj kev sib luag thiab kev tswj xyuas zoo hauv kev tsim khoom thiab kev siv ferromanganese.
Cov khoom zoo sib xws: Spiegeleisen (Specular npua hlau):
Spiegeleisenyog lwm cov khoom siv nrog cov ntsiab lus siab manganese siv hauv kev lag luam steel, zoo li ferromanganese hauv qee qhov kev siv.
Nws ua lub luag haujlwm tseem ceeb hauv kev hloov kho cov khoom ntawm hlau thiab hlau, pab txhawb rau lawv lub zog thiab kav ntev.
Thaum ob qho tib si ferromanganese thiab spiegeleisen sib piv, lawv muaj cov yam ntxwv tshwj xeeb, ua rau lawv haum rau cov hom phiaj metallurgical.
Tshaj li Steel Kev Lag Luam:
Ferromanganese pom cov ntawv thov dhau ntawm kev lag luam hlau, suav nrog cov hlau tsis muaj hlau, qhov uas nws ua raws li tus neeg sawv cev txo qis rau kev tsim cov hlau xws li molybdenum thiab chromium.
Kev tsim khoom ntawm stainless hlau cia siab rau kev tswj xyuas cov ntsiab lus ntawm manganese hauv ferromanganese kom ua tiav cov khoom tshwj xeeb.
Environmental Considerations:
Kev tsim cov ferromanganese, tshwj xeeb tshaj yog los ntawm cov txheej txheem ib txwm siv cov pa roj carbon monoxide, ua rau cov pa roj carbon dioxide emissions thiab ua rau muaj kev cuam tshuam hauv tsev cog khoom.
Kev siv zog txuas mus ntxiv yog ua los tshawb nrhiav lwm txoj hauv kev tsim khoom lossis tsim cov txheej txheem carbon-neutral los txo qhov cuam tshuam ib puag ncig ntawm ferromanganese ntau lawm.
Yav tom ntej Outlook:
Raws li kev siv thev naus laus zis thiab kev txhawj xeeb txog kev ruaj ntseg loj tuaj, tej zaum yuav muaj kev txhim kho ntxiv hauv kev tsim khoom thiab kev siv ferromanganese.
Cov kws tshawb fawb thiab cov kws tshaj lij kev lag luam yuav tsom mus rau kev txhim kho cov txheej txheem tsim khoom, txo kev cuam tshuam ib puag ncig, thiab tshawb nrhiav cov ntawv thov tshiab rau ntau yam ferroalloy no.
Hauv kev xaus, ferromanganese yog ib qho tseem ceeb hauv kev tsim cov hlau, muab ntau qib rau cov kev xav tau sib txawv. Nws daim ntawv thov txuas ntxiv tshaj cov hlau mus rau cov hlau tsis muaj hlau thiab cov hlau tsis muaj hlau ntau lawm. Raws li kev ruaj ntseg dhau los ua qhov kev txhawj xeeb tseem ceeb dua, kev lag luam tseem tab tom nrhiav txoj hauv kev los txo qhov kev cuam tshuam ib puag ncig ntawm ferromanganese ntau lawm thaum tshawb nrhiav qhov muaj peev xwm tshiab rau nws siv.
75 feem pua High Carbon Ferro Manganese yog siv los ntxiv cov yam ntxwv tshwj xeeb rau cov hlau thiab cam khwb cia hlau rau ntau yam kev siv. Yeej, nws yog cov hlau alloy uas feem ntau muaj cov nyiaj manganese ntau hauv nws cov muaj pes tsawg leeg. Cov hlau no muaj rau peb nyob rau hauv 10mm mus rau 150 hli ntawm granule loj uas yog cov zoo ib yam thiab zoo ib yam. Peb tau siv peb cov tshuab niaj hnub no, arc rauv thiab forging unit los hloov hlau ore rau HC Ferro Manganese.
High carbon ferromanganese (HC FeMn) yog ib qho hlau alloy feem ntau muaj manganese, hlau thiab 2 feem pua ~ 8 feem pua ntawm cov pa roj carbon.
Nws yog dav siv hauv steelmaking li deoxidizer thiab alloy additive uas txhim kho lub zog thiab kev ua haujlwm ntawm cov hlau. Nws kuj yog siv nyob rau hauv zus tau tej cov refined ferromanganese. Peb cov khoom HC FeMn yog tsim los ntawm EAF.
