Taw qhia
Cov pa roj carbon ferromanganese nruab nrab yog ib qho alloy uas muaj manganese thiab hlau. Ferromanganese yog feem ntau siv deoxidizer thiab alloying khoom hauv steelmaking. Nws yog dav siv nyob rau hauv structural steel, cuab yeej steel, tshav kub-resistant stainless hlau, hnav-resistant steel thiab lwm yam hlau alloys. Nruab nrab thiab qis carbon ferromanganese tuaj yeem muab faib ua cov pa roj carbon tsawg ferromanganese nrog cov ntsiab lus carbon tsawg dua 0.7% thiab nruab nrab carbon ferromanganese nrog cov ntsiab lus carbon ntawm 0.7%-2. 0%.
Khoom siv
Cov khoom siv raw rau kev tsim cov khoom nruab nrab thiab qis carbon ferromanganese los ntawm cov txheej txheem electro-silicothermic suav nrog manganese ore, manganese-silicon alloy thiab txiv qaub. Sinter ore thiab manganese-nplua nuj slag yuav tsum tsis txhob siv nyob rau hauv smelting nruab nrab thiab tsawg-carbon ferromanganese. Qhov loj me ntawm manganese ore yuav tsum tsis txhob siab tshaj 50 hli, thiab cov dej noo yuav tsum tsawg dua 6%. Cov ntsiab lus ntawm cov manganese-silicon alloy yuav tsum tau txiav txim siab raws li cov ntsiab lus ntawm cov pa roj carbon monoxide nruab nrab-tsawg ferromanganese smelted, thiab qhov siab dua cov ntsiab lus ntawm manganese, qhov zoo dua. Feem ntau cov ntsiab lus manganese yog 67% ~ 69%. Thaum siv cov khoom siv txias txias, qhov me me ntawm cov manganese-silicon alloy yog tsawg dua 30 hli, thiab cov pa roj carbon ntau yog tshem tawm. Thaum siv cov kua manganese-silicon alloy sib tov, cov slag raug tshem tawm thaum lub sij hawm Perrin txheej txheem.
The requirements for lime are: CaO>85%, P Tsawg dua lossis sib npaug rau 0.02%, SiO<3%, particle size 8~40mm, no carbonaceous inclusions and powdery, unburned lime should not be used.
Txheej txheem
Muaj peb txheej txheem ntau lawm rau nruab nrab carbon ferromanganese: txheej txheem electro-silicothermic, co rauv txheej txheem thiab oxygen tshuab.
Cov txheej txheem electro-silicothermic yog siv manganese ore los ua kom zoo thiab desiliconize manganese-silicon alloy nyob rau hauv refining hluav taws xob arc rauv (tilting graphite electrode hluav taws xob arc rauv) (uas yog, siv manganese-silicon alloy los txo manganese ore) kom tau nruab nrab thiab tsawg carbon ferromanganese. Nws yog txoj hauv kev tseem ceeb rau smelting nruab nrab thiab qis carbon ferromanganese tam sim no.
Raws li lub xeev sib txawv ntawm cov ntaub ntawv them nyiaj, nws tau muab faib ua txoj kev them nyiaj txias thiab txoj kev them nyiaj kub. Txoj kev them nyiaj txias yog ib txoj hauv kev los ua cov khoom nruab nrab thiab qis carbon ferromanganese. Lub refining rauv siv yog tilting graphite electrode hluav taws xob arc rauv.
