FerromanganeseDaim ntawv qhia nqe rau siv:

Ib qho hlau alloy tsim los ntawm manganese thiab hlau. Cov pawg tseem ceeb: cov pa roj carbon ntau ferromanganese (muaj 7% carbon), nruab nrab carbon ferromanganese (muaj 1.0 ~ 1.5% carbon), qis carbon ferromanganese (muaj 0.5% carbon), metallic manganese, iav hlau, silicon-manganese alloy.

Hauv steelmaking, nws yog siv los ua deoxidizer thiab alloy additive, thiab yog cov feem ntau siv ferrous alloy. Cov kev cai dav dav rau manganese ore siv hauv smelting ferromanganese yog tias ferromanganese muaj 30 ~ 40% manganese, manganese-hlau piv yog ntau dua 7, thiab phosphorus-manganese piv tsawg dua 0.003. Ua ntej smelting, manganese carbonate ore yuav tsum tau roasted thiab cov hmoov ore yuav tsum tau sintered thiab agglomerated.

Ores uas muaj hlau siab thiab phosphorus feem ntau tsuas yog siv ua ke, lossis manganese-nplua nuj slag nrog tsawg hlau thiab phosphorus tsawg tuaj yeem tsim los ntawm kev xaiv txo. Coke yog siv los ua tus neeg sawv cev txo qis thaum smelting, thiab qee lub tsev lag luam kuj siv cov thee ntshiv lossis anthracite. Cov khoom siv raw khoom feem ntau yog txiv qaub, thiab silica feem ntau ntxiv thaum smelting manganese-silicon alloy.

Cov txheej txheem thoob ntiaj teb rau carbon ferromanganese yog tias nws muaj 75 txog 80% manganese. Txhawm rau hloov mus rau cov khoom siv raw khoom ntawm qib qis manganese ore, Tuam Tshoj tau teev cov npe nrog cov ntsiab lus qis manganese (lub cub hluav taws xob ferromanganese muaj ntau dua 65% manganese, thiab blast furnace ferromanganese muaj 50% manganese. % saum toj no). Yav dhau los, blast furnaces feem ntau yog siv los smelt carbon ferromanganese. Nrog rau txoj kev loj hlob ntawm kev lag luam hluav taws xob hluav taws xob, kev siv hluav taws xob hauv hluav taws xob tau maj mam nce.
