Cov pa roj carbon ntau ferromanganese yog cov alloy uas muaj cov ntsiab lus carbon feem ntau ntawm 1.0% thiab 3.0%. Cov hlau no feem ntau yog tsim los ntawm manganese, hlau, thiab carbon, thiab muaj lub cev zoo thiab cov khoom siv zoo xws li lub zog siab, hnav tsis kam, thiab corrosion kuj. Kev siv cov pa roj carbon ntau ferromanganese yog qhov dav heev, xws li hauv cov hlau, tsheb, aerospace, thiab lwm yam.
Manganese hlau kuj tau siv dav hauv casting. Nws tuaj yeem muab ntxiv los ua cov khoom siv alloying rau casting alloys los txhim kho lawv lub zog, hardness, corrosion kuj, thiab hnav tsis kam. Thaum lub sij hawm casting txheej txheem, manganese hlau kuj tau ntxiv raws li ib tug inoculant rau cam khwb cia hlau los txhim kho qhov ceev thiab mechanical zog ntawm lub castings.
Hauv cov ntsiab lus, raws li cov khoom siv tseem ceeb alloy, cov pa roj carbon ntau ferromanganese muaj qhov tseem ceeb ntawm kev lag luam thiab kev lag luam xav tau ntawm nws cov ntsiab lus carbon thiab daim ntawv thov hauv casting. Nrog kev nce qib ntawm cov thev naus laus zis thiab kev nthuav dav ntawm daim ntawv thov teb, daim ntawv thov kev cia siab ntawm cov pa roj carbon manganese hlau yuav ntau dua.
