Dab tsi yog ferromanganese siv rau?
Ferromanganese (FEMN) feem ntau siv los ua tus nqi -}}} Siv cov qauv manganese ua tau los ntxiv hlau thiab cam khwb cia hlau.Nws ua haujlwm ob qhov tseem ceeb, ib txhij muaj zog:
1.
Lij cov ntsiab lus:Manganese yog qhov tseem ceeb tshaj plaws ua ke uas txhim kho cov khoom ntawm cov hlau:
•
Lub zog thiab Hardness:Nws nce lub zog tensile thiab Hardness ntawm cov hlau.
•
Tougness thiab ductility:Nws txhim kho cov khoom siv lub peev xwm los nqus qhov kev cuam tshuam tsis muaj kev tawg (tawv) thiab kom tsis muaj kev tawm tsam yam tsis muaj kev tawg (ductility).
•
Ua haujlwm:Manganese ua rau cov hlau ntau ntxiv rau kub dov thiab zam.
2.
Desulfurizer (kev ua haujlwm tseem ceeb):Nov yog ib qho ntawm nws txoj haujlwm tseem ceeb tshaj plaws. Sulfur yog ib hom neeg impurity hauv hlau ore thiab coke uas ua rau cov hlau ua kom tawg thiab tawg ntawm qhov kub ("Kub luv"). Manganese muaj kev sib txawv rau cov leej faj thiab kev tawm tsam nrog nws los uaManganese sulfide (MNS), Uas muaj qhov tseem ceeb melting taw tes thiab tau faib ua kom tsis muaj teeb meem thoob plaws hauv cov hlau hauv Glogular daim ntawv. Qhov no neutralizes sulfur qhov tsis zoo.
Cov Ntawv Thov Tseem Ceeb:
•
Cov Hlau Carbon:Feem coob ntawm ferromanganese yog siv nyob rau hauv kev tsim cov hlau nplaum (piv txwv li, siv rebar, cov kab teeb duab).
•
Siab - muaj zog tsawg -} alloy (hsla) hlau:Siv Hauv Kev Siv Hluav Taws Xob, cov choj, thiab cov raj dej thiab cov raj.
•
Nrum Hlau:Ntxiv rau txhim kho lub zog thiab kev sib luag.
Cas yog ferromanganese tsim?
Ferromanganese yog feem ntau tsim nyob rau hauv aSubmerged Arc Rauv (Saf), Uas yog ib qho hluav taws xob arc rauv tshwj xeeb tsim rau smelting ferroalloys.
Cov txheej txheem (carbothermic txo):
1.
Cov Khoom Siv Raw:Cov khoom siv raw tseem yog:
•
Manganese ores:(Feem ntau pyolusite, mnoos)
•
Txo tus neeg saib xyuas:Coke lossis thee (qhov chaw ntawm carbon)
•
Flux:Limestone lossis dolomite (los tswj cov acidity thiab daim ntawv slag)
2.
Blending thiab Sintering:Lub ores feem ntau xyaw kom ua tiav qib qib ib thiab tom qab ntawd sintered (agglomerated rau hauv ib qho chaw sib xyaw huab cua) txhawm rau txhim kho kev ua kom sov.
3.
SMELTING:Cov kab mob sib xyaw ua ke yog pub tsis tu ncua mus rau sab saum toj ntawm submerged arc rauv. Cov electrodes haib submerged hauv tus nqi tsim kom muaj cua sov heev.
•
Cov pa roj carbon (Coke) txo cov manganese oxides hauv cov kev sib tw. Tus tseem ceeb tshuaj tiv thaiv rau siab- revbon femn yog:
MNO + C → MN + CO
•
Flux sib xyaw ua ke nrog impurities los ua ib qho kev sib dhos uas ntab uas ntab rau saum cov hlau hnyav.
4.
Tapping:Lub Molten Ferromanganese (Alloy) tau muab los ntawm hauv qab ntawm cov cub tawg rau hauv cov ladle thiab nrum rau hauv cov block loj, uas yog tom qab ntawd crushed rau qhov yuav tsum tau muag.
Daim ntawv tseem ceeb:Tsawg {{0 {}}} -}}} Cov ntsiab lus los txo cov ntsiab lus carbon) es tsis yog smelting.
