Manganese yog ib qho tseem ceeb tshaj plaws alloying ntsiab nyob rau hauv cov ntaub ntawv hlau thiab hlau. Manganese tuaj yeem hloov lub zog, hardness, toughness, hnav tsis kam, kub tsis kam thiab lwm yam khoom ntawm hlau thiab hlau. Manganese nyob rau hauv cov ntaub ntawv hlau thiab hlau yog tsuas yog tau los ntawm kev ntxiv ferromanganese alloy rau nws yaj.
Ferromanganese tuaj yeem muab faib ua cov pa roj carbon siab, cov pa nruab nrab thiab cov pa roj carbon tsawg ferromanganese vim muaj cov ntsiab lus sib txawv. Ntawm lawv, siab carbon ferromanganese yog nruj me ntsis txwv vim nws cov ntsiab lus carbon siab, uas yuav ua rau kom cov pa roj carbon ntsiab lus ntawm hlau thaum ntxiv rau steel cov ntaub ntawv. Vim nws cov ntsiab lus tsis tshua muaj carbon ferromanganese tsawg, tsis muaj teeb meem zoo li cov pa roj carbon ferromanganese. Yog li ntawd, tsawg-carbon ferromanganese yog siv ntau tshaj li high-carbon ferromanganese. Nws yog ib qho tseem ceeb raw khoom rau zus tau tej cov stainless hlau, tshav kub-resistant cam khwb cia hlau, tshav kub-resistant cam khwb cia hlau, hnav-resistant steel thiab structural steel. Yav dhau los, kev tsim cov pa roj carbon tsawg ferromanganese feem ntau yog los ntawm tshuab pa thiab decarburization rau hauv cov kua roj carbon ntau ferromanganese yaj los hloov cov pa roj carbon ferromanganese rau hauv cov pa roj carbon tsawg ferromanganese, thiab tom qab ntawd siv silicon manganese alloy los txo cov oxidized yaj. txhim kho cov txiaj ntsig ntawm manganese. Cov txheej txheem tsim cov kua oxidation decarbonization ntawm cov pa roj carbon ferromanganese yog qhov nyuaj, tus nqi siab thiab muaj kuab paug ib puag ncig.
