Ferrosilicon yog cov hlau alloy uas muaj hlau thiab silicon ua los ntawm coke, steel khib nyiab thiab quartz (los yog silicon). Nws yog dav siv nyob rau hauv cov hlau, foundry thiab ferroalloy industries raws li ib tug deoxidising thiab alloying tus neeg saib xyuas, raws li ib tug inoculum thiab spheroidising tus neeg saib xyuas, thiab raws li ib tug txo tus neeg saib xyuas. Silicon manganese kuj muaj deoxidising thiab desulfurising teebmeem. Tsis tas li ntawd, silicon manganese tuaj yeem ua kom huv si molten hlau zoo.
Ferrosilicon feem ntau yog siv hauv kev tsim steel thiab magnesium hlau ntau lawm. Silicomanganese yog ferroalloy nrog daim ntawv thov dav thiab ntim ntau lawm. Nws siv manganese ore (xws li manganese slag), coke thiab silicon ua raw khoom. Nws yog tsuas yog siv nyob rau hauv steelmaking thiab yog siv los ua composite deoxidising thiab alloying tus neeg sawv cev. Nws kuj yog siv rau ib qho twg. Nws yog siv los ua tus neeg sawv cev desulfurising.
(1) Kev sib xyaw ntawm ferrosilicon
Cov khoom siv tseem ceeb rau kev tsim cov ferrosilicon yog silica, xiav thee thiab hlau oxide nplai. Ntawm lawv, silica yog lub hauv paus tseem ceeb ntawm silicon caij (Si) hauv ferrosilicon; Cov pa roj carbon xiav feem ntau yog siv los ua cov pa roj carbon tsawg los txo cov khoom siv silicon hauv silicon; hlau oxide feem ntau yog siv los ua cov khoom siv hlau los kho cov ntsiab lus ntawm ferrosilicon, tshwj xeeb tshaj yog hlau, txhawb kev txo cov silica hauv silicon.
(2) Kev sib xyaw ntawm manganese silicon
Cov ntaub ntawv tseem ceeb rau kev tsim cov manganese silicon alloy yog manganese ore (xws li manganese-muaj slag), coke, silica, thiab lwm yam. Tus nqi ntawm manganese ore yog li 60% ntawm tus nqi ntawm cov khoom manganese-silicon.
