Ferromanganese o se ituaiga o ferroalloy e aofia ai le uʻamea ma le manganese. e faia e ala i le faʻavevelaina o se faʻafefiloi o le oxides MnO2 ma Fe2O3, ma le carbon, e masani lava e pei o le koale ma le coke, i totonu o se ogaumu faʻafefe poʻo se faʻaogaina o le ogaumu eletise, e ta'ua o le ogaumu arc ua goto.O oxides e faʻaitiitia le faʻaitiitia o le carbothermal i totonu o ogaumu, e maua ai le ferromanganese.
E mafai ona vaevaeina i High carbon ferromanganese/HCFeMn(C:7.0%-8.0%), Medium carbon ferromanganese/MCFeMn:(C:1.0-2.0%), ma Low carbon ferromanganese/LCFeMn(C<0.7%).e maua i le tele o lapopoa .
O le gaosiga o le Ferromanganese e faʻaaogaina ai le manganese e fai ma mea mata ma le lime e fai ma mea fesoasoani, faʻaaogaina ogaumu eletise e faʻafefe ai.
Talosaga:
①Ferromanganese e lelei le faʻaogaina o le uʻamea, o le deoxidizer ma le faʻafefiloi o mea, ma i le taimi nei e mafai ona faʻaitiitia ai le sulfur ma faʻaleagaina e mafua mai i le sulfur.
②Aila vai fa'afefiloi e le ferromanganese e mafai ona fa'aleleia mea fa'ainisinia o le sila ma le malosi maualuga, ma'a'a, tete'e fa'aofuofu, ductility, ect.
③Ferromanganese ose mea taua tele fesoasoani i le u'amea ma le u'amea alamanuia.
