Manganese muaj kev sib raug zoo rau cov pa oxygen thiab tuaj yeem tsim cov manganese oxide ruaj khov nrog oxygen. Tsis tas li ntawd, ferromanganese, raws li cov khoom siv alloying ntxiv, tuaj yeem txhim kho hardness, ductility, toughness thiab hnav tsis kam ntawm hlau. Nws yog dav siv hauv cov qauv hlau, cov cuab yeej hlau, cov hlau tsis muaj cua sov-resistant, hnav-resistant steel thiab lwm yam hlau alloy. Manganese kuj muaj lub luag haujlwm ntawm desulphurisation thiab txo cov teebmeem ntawm sulfur. 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 0.7%-2.{{7} }%.
Nruab nrab carbon ferromanganese lub ntsiab siv ferromanganese, manganese thiab hlau tsim los ntawm hlau alloy, kev txhim kho kev lag luam thiab kev siv technology, kev thov rau ntau thiab ntau dua, nws siv dab tsi, tuaj yeem siv dav heev.
Ferromanganese carbon thoob ntiaj teb tus qauv dav dav rau cov ntsiab lus manganese ntawm 75 ~ 80%, Tuam Tshoj txhawm rau hloov mus rau qib qis ntawm manganese ore raw khoom, cov kev cai ntawm qis manganese-muaj qib (hluav taws xob rauv ferromanganese uas muaj manganese ntau dua 65% , blast furnace ferromanganese uas muaj manganese ntau dua 50 feem pua). Smelting ntawm cov pa roj carbon ferromanganese siv los ua cov khoom siv hluav taws xob feem ntau hauv lub tshuab hluav taws xob, nrog rau kev tsim hluav taws xob kev lag luam, kev siv hluav taws xob hluav taws xob maj mam nce.
Hauv steelmaking, nws yog siv los ua deoxidiser thiab alloy additive, thiab nws yog ferroalloy nrog ntau npaum li cas. Smelt ferromanganese nrog manganese ore feem ntau yuav tsum muaj manganese 40 ~ 50%, manganese thiab hlau piv ntawm ntau tshaj 7, phosphorus thiab manganese piv tsawg dua 0.003. Ua ntej smelting, manganese carbonate ore yuav tsum tau roasted, hmoov ore yuav tsum tau sintered los ua ib qho thaiv. Ores nrog cov hlau siab thiab phosphorus cov ntsiab lus tsuas yog siv ua ke, lossis los ntawm kev xaiv txo kom tau txais cov hlau tsis tshua muaj thiab tsis muaj phosphorus manganese-nplua nuj slag. Coke yog siv los ua tus txo tus neeg sawv cev hauv smelting, thiab lean thee lossis anthracite kuj siv hauv qee cov nroj tsuag. Cov ntaub ntawv tseem ceeb yog cov txiv qaub, thiab silica feem ntau yog ntxiv thaum smelting manganese-silicon alloys.
