Ferrosilicon yog ib hom ferroalloy, muaj li ntawm hlau thiab silicon, uas yog ib qho tseem ceeb raw khoom rau hlau thiab steel kev lag luam. Ferrosilicon feem ntau yog ua los ntawm melting silicon-muaj cov ntaub ntawv raw thiab hlau-muaj raw cov ntaub ntawv nyob rau hauv ib tug tej yam kev faib ua feem nyob rau hauv ib tug ntxhia tshav kub rauv. Cov khoom siv raw cov khoom sib tov yog txuas ntxiv yaj nyob rau hauv ib qho chaw kub kub, ua cov tshuaj tiv thaiv thiab lub xeev ua kua, uas yog poured rau hauv ferrosilicon. Cov txheej txheem ntau lawm ntawm ferrosilicon feem ntau suav nrog batching, sib tov rau hauv cub tawg, smelting, pouring, xov thiab cia.
Kev tsim cov ferrosilicon feem ntau xav tau cov khoom siv hlau, suav nrog cov khoom siv silicon, steel chips thiab lwm yam. Ntawm lawv, qhov zoo ntawm ferrosilicon feem ntau cuam tshuam los ntawm cov khoom siv hlau zoo; Feem ntau ntawm cov khoom siv silicon yog quartzite thiab quartzite. Cov ntsiab lus ntawm silicon dioxide yog siab dua 97%, cov ntsiab lus tsis muaj impurity, sib sau ua ke hu ua silicon dioxide; Orchid carbon yog maj mam dhau los ua cov khoom siv tsis hloov pauv nrog cov tshuaj lom neeg ua haujlwm siab, cov ntsiab lus tsis tshua muaj txhuas, cov ntsiab lus tsis muaj sulfur thiab cov ntsiab lus phosphorus tsawg. Tsis tas li ntawd, ferrosilicon ntau lawm yuav tsum tau them nqi hluav taws xob, uas suav nrog ntau tus nqi. Kev tsim cov ferrosilicon cuam tshuam rau kev muab khoom ntawm ferrosilicon hauv khw, uas cuam tshuam rau kev lag luam tus nqi ntawm ferrosilicon.
Txhawm rau kom tau txais cov tshuaj muaj txiaj ntsig zoo thiab ua kom cov hlau zoo, nws yog qhov yuav tsum tau deoxidise nyob rau theem kawg ntawm steelmaking. Silicon thiab oxygen ua ke yooj yim tsim silica, yog li silicon yog siv rau nag lossis daus thiab diffusion deoxidation. Kev tsim khoom ntawm ib tonne ntawm 75% ferrosilicon siv kwv yees li 1,800 kg ntawm silica, 920 kg ntawm coke, 220 kg ntawm steel chips, 50 kg ntawm electrode paste thiab 8,500 kg ntawm hluav taws xob.
