Ferrosilicon yog ib qho hlau alloy uas muaj hlau thiab silicon, tam sim no ferrosilicon muaj ntau yam kev siv, ferrosilicon kuj tseem siv tau los ua cov khoom siv alloying ntxiv tus neeg sawv cev, dav siv hauv cov hlau tsis tshua muaj hlau, caij nplooj ntoos hlav steel, bearing steel, kub-resistant steel. thiab hluav taws xob silicon steel, ferrosilicon hauv kev tsim cov ferroalloys thiab kev lag luam tshuaj, feem ntau siv los ua tus neeg sawv cev txo qis. Txawm li cas los xij, ntau tus neeg tsuas yog nkag siab txog kev siv ferrosilicon, thiab tsis nkag siab txog kev smelting ntawm ferrosilicon thiab smelting teeb meem yuav pom.
Txhawm rau kom muaj peev xwm nkag siab koj txoj kev nkag siab ntawm ferrosilicon, ferrosilicon cov neeg muag khoom tsuas yog txheeb xyuas cov laj thawj rau cov ntsiab lus qis hauv ferrosilicon.
Yog vim li cas vim li cas cov smelted ferrosilicon muaj cov pa roj carbon tsawg feem ntau yog vim lub fact tias thaum smelting ferrosilicon, cov chaw tsim tshuaj paus yuav siv coke raws li ib tug txo tus neeg sawv cev, ua kom nws yooj yim mus nce cov pa roj carbon ntawm tus kheej-ci electrode, siv coke cib los tsim. lub qhov hluav taws xob hlau thiab cov dej ntws ntawm cov hlau troughs, qee zaum siv cov hmoov graphite los pleev xim rau cov pwm pwm, thiab siv cov charcoal qauv diav coj cov qauv ua kua thiab lwm yam. Nyob rau hauv luv luv, smelting ferrosilicon los ntawm lub cub tawg cov tshuaj tiv thaiv kom txog rau thaum hlau, pouring txheej txheem, thiab carbon sib cuag lub sij hawm yog obviously ntau. Ferrosilicon silicon cov ntsiab lus nyob rau hauv siab dua, qhov qis nws cov ntsiab lus carbon.
Ferrosilicon nyob rau hauv silicon cov ntsiab lus ntawm ntau tshaj 30 ﹪, ferrosilicon nyob rau hauv feem ntau ntawm cov pa roj carbon yog rau silicon carbide (SiC) xeev. Silicon carbide yog yooj yim oxidised los ntawm silicon dioxide los yog silicon monoxide nyob rau hauv lub crucible thiab yog txo. Silicon carbide nyob rau hauv ferrosilicon, tshwj xeeb tshaj yog thaum qhov kub thiab txias, nws solubility yog heev me me, yooj yim rau precipitate thiab ntab. Yog li ntawd, silicon carbide nyob rau hauv ferrosilicon yog tsawg heev, yog li cov pa roj carbon ntsiab lus ntawm ferrosilicon yog tsawg heev.
