ferromanganese
Nws yog ib qho ntawm cov neeg ua haujlwm tseem ceeb alloying siv hauv kev lag luam steel.

National standard ntau yam
Cov txheej txheem no qhia txog kev faib khoom, kev xav tau, kev lees paub, kev soj ntsuam cov cai, ntim, khaws cia thiab kev thauj mus los, kos npe thiab daim ntawv pov thawj zoo ntawm ferromanganese. Cov qauv no muaj feem xyuam rau ferromanganese siv los ua deoxidizer thiab alloying ntsiab additive rau steelmaking thiab casting.

Technical xwm txheej
Peb tau yeej ntau yam khoom plig rau kev muaj tswv yim zoo
Niaj hnub nimno loj-scale ferromanganese txo qhov cub muaj peev xwm ntawm 40, 000 ~ 75, 000 kVA, feem ntau tsau kaw. Lub smelting zog noj ntawm txoj kev flux yog feem ntau 2500 ~ 3500 kW · h / tuj, thiab lub hwj chim noj ntawm txoj kev uas tsis yog flux yog 2000 ~ 3000 kW · h / tuj.
Hluav taws xob rauv refining
Nruab nrab thiab qis carbon ferromanganese feem ntau desilicated thiab refined los ntawm 1500 ~ 6000 kVA hluav taws xob rauv, nrog manganese silicon, manganese nplua nuj ore thiab txiv qaub li raw cov ntaub ntawv.
Cov tshuaj tiv thaiv yog: MnSi+2MnO+2CaO -- →3Mn+2CaO·SiO2
Kev siv cov txheej txheem siab slag tuaj yeem txo cov manganese cov ntsiab lus ntawm slag thiab txo cov manganese poob los ntawm slag tso tseg. Hauv kev sib koom ua ke, cov slag nrog qis qis (CaO / SiO2 tsawg dua 1.3) yog ua haujlwm, thiab cov slag nrog cov ntsiab lus siab manganese (20 ~ 30%) yog siv rau smelting manganese silicon alloy. Lub preheating ntawm tus nqi lossis kev thauj khoom ntawm cov kua manganese silicon alloy tuaj yeem txo lub sijhawm smelting thiab txo lub zog noj. Refining fais fab mov feem ntau yog li 1000 kW · h. Nruab nrab thiab qis carbon ferromanganese kuj yog tsim los ntawm thermal blending ntawm kua manganese-silicon alloy nrog manganese ore thiab txiv qaub yaj.
gas tshuab refining
Nruab nrab thiab qis carbon ferromanganese tuaj yeem tsim los ntawm tshuab ua kua carbon ferromanganese lossis manganese silicon alloy nrog cov pa ntshiab. Tom qab xyoo ntawm kev sim kev tshawb fawb, txoj kev no nkag mus rau hauv kev lag luam nplai ntau lawm hauv 1976. Los ntawm "Global Ferroalloy Network Ntiaj Teb Ferroalloy network Ntiaj Teb Ferroalloy network Ntiaj Teb Ferroalloy network"
hluav taws xob rauv smelting
Txo smelting ntawm ferromanganese muaj ob hom flux txoj kev (tseem hu ua low manganese slag method) thiab tsis muaj flux method (high manganese slag method). Lub hauv paus ntsiab lus ntawm cov txheej txheem flux yog tib yam li cov blast furnace smelting, tshwj tsis yog tias lub zog hluav taws xob hloov cov coke siv rau cua sov. Los ntawm kev ntxiv cov txiv qaub los ua cov txheej txheem siab slag (CaO/SiO{{0}}.3 ~ 1.6) kom txo qis manganese. Cov hlau tsis tshua muaj thiab tsis tshua muaj phosphorus manganese nplua nuj slag nrog qis alkalinity (CaO / SiO2 tsawg dua 1.0) thiab cov ntsiab lus siab manganese yog tsim los ntawm fluxless smelting yam tsis muaj txiv qaub. Nyob rau hauv txoj kev no, tus nqi ntawm slag yog me me, lub zog noj yuav txo tau, thiab evaporation poob ntawm manganese yuav txo tau vim yog slag kub. Nyob rau tib lub sijhawm, cov khoom lag luam manganese nplua nuj slag (muaj 25 ~ 40% manganese) tuaj yeem siv los ua cov khoom siv raw rau smelting manganese silicon alloy, thiab kev rov qab zoo ntawm manganese yog siab dua (ntau dua 90%). Kev lag luam niaj hnub no feem ntau siv cov ferromanganese flux-free smelting ntawm carbon ferromanganese, thiab tsim cov txheej txheem tsim khoom nrog manganese silicon alloy thiab smelting ntawm nruab nrab thiab qis carbon ferromanganese.
