Yuav ua li cas yog ferromanganese cais?
Ferromanganese yog Ferrroalloy feem ntau tsim ntawm cov hlau (FE) thiab manganese (mn), nrog sib txawv carbon (c) cov ntsiab lus. Nws tau faib raws li nws tus manganese thiab cov ntsiab lus carbon, uas txiav txim nws cov kev siv tshwj xeeb hauv metallurgy. Cov thawj kev faib tawm yogHigh - farbon ferromanganese (MC FEMON), LC FLNON FREROMEARANESE (LC FEMN), thiab Silicomanganese (Simn)Cov. Hauv qab no yog cov ncauj lus kom ntxaws:
|
|
Manganese (MN) cov ntsiab lus (%)
|
Carbon (c) cov ntsiab lus (%)
|
|
|
|
High - bevon freadbon ferromanganese (HC FEMN)
|
|
|
Moj tej tawg sov rauv lossis hluav taws xob arc rauv (EAF)
|
Siv rau hauv steelmaking rau deoxidation thiab kev sib txuas; Tus nqi -} Siv tau zoo rau Bulk Steel ntau lawm.
|
|
Nruab nrab - rhawv zeb freterganganese (MC FEMN)
|
|
|
Txo cov nkauj kom txo qis (huv HC FEMN)
|
Thov siv rau hauv high - Cov hlau zoo uas muaj cov tshuaj tua hluav taws xob uas xav tau (piv txwv li cov qauv hlau style).
|
|
Tsawg - recbon freteranganese (LC FEMN)
|
|
|
Electrolytic lossis kho cov txheej txheem (nqus tsev lossis tshuab pa oxygen)
|
Qhov tseem ceeb rau stainless thiab qis {- cov roj carbon hlau uas muaj cov pa roj carbon minimal yog qhov tseem ceeb.
|
|
|
|
|
|
Siv rau deoxidation, desulfurization, thiab silicon {{{}}}} manganese siv hauv hlau.

Cov ntsiab lus tseem ceeb ntawm kev faib tawm:
High - Carbon FEMN (HC FEMN):Qhov feem ntau dav tsim vim nws tus nqi qis dua thiab siab manganinal tawm los. Muaj 6-7% carbon, ua rau nws haum rau cov hlau dog dig tab sis tsis yog rau high- purity application.
Nruab nrab - revbon femn (MC FEMN):Tsim los ntawm refining hc fem nrog silicon lossis oxygen, txo cov roj carbon rau 0.8-1.5%. Siv hauv Alloy cov hlau yuav tsum tau muaj cov tshuaj tiv thaiv carbon.
Tsawg - revbon femn (LC FEMN):Ntxiv ua kom zoo dua kom ua tiav<0.5% carbon, often via vacuum or oxygen blowing. Critical for stainless steel and special alloys.
Silicomanganese (Simn):Muaj ob qho tib si silicon (14-18%) thiab manganese, ua yeeb yam ua tus neeg saib xyuas thiab cov neeg sawv cev sib piv.
Kev faib tawm kom ntseeg tau tias cov me nyuam cathmakers xaiv cov hom tsim nyog ferriganganese raws li cov ntsiab lus manganese, cov tshuaj carbon txwv, thiab qib qauv.
