Menene ferrosilicon?

Ferrosilicon wani ferroalloy ne wanda ya hada da baƙin ƙarfe da silicon.Ferrosilicon siliki ne da aka yi ta hanyar narke coke, aske karfe, da quartz (ko silica) a cikin tanderun lantarki.Tun da silicon da oxygen ana sauƙin haɗa su cikin silicon dioxide, ferrosilicon galibi ana amfani dashi azaman deoxidizer wajen yin ƙarfe.A lokaci guda, saboda SiO2 yana haifar da zafi mai yawa, yana da amfani don ƙara yawan zafin jiki na narkakkar karfe yayin deoxidation.A lokaci guda, ferrosilicon kuma za a iya amfani da a matsayin alloying kashi ƙari, kuma ana amfani da ko'ina a cikin low gami tsarin karfe, spring karfe, qazanta karfe, zafi-resistant karfe da lantarki silicon karfe.Ferrosilicon galibi ana amfani dashi azaman wakili mai ragewa a cikin samar da ferroalloy da masana'antar sinadarai.
