Baya ga yin amfani da ƙarfe, ferrosilicon kuma ana amfani dashi azaman deoxidizer a cikin narkewar ƙarfe na magnesium. Tsarin ƙera ƙarfe wani tsari ne wanda aka zubar da narkakkar ƙarfe a cikinsa kuma yana kawar da datti mai cutarwa kamar phosphorus da sulfur ta hanyar busa iskar oxygen ko ƙara oxidants. Yayin aiwatar da yin ƙarfe daga ƙarfe na alade, abun cikin iskar oxygen a cikin narkakkar karfe yana ƙaruwa a hankali, kuma FeO gabaɗaya yana wakilta a cikin narkakkar karfe. Idan yawan iskar oxygen da ya rage a cikin karfe ba a cire shi daga siliki-manganese gami ba, ba za a iya jefa shi cikin ƙwararren ƙarfe na ƙarfe ba, kuma ba za a iya samun ƙarfe mai kyawawan kaddarorin inji ba.
Don yin wannan, yana da mahimmanci don ƙara wasu abubuwa waɗanda ke da ƙarfi mai ƙarfi tare da iskar oxygen fiye da baƙin ƙarfe, kuma waɗanda oxides suna da sauƙin cirewa daga narkakken ƙarfe a cikin slag. Dangane da ƙarfin dauri na abubuwa daban-daban a cikin narkakken ƙarfe zuwa oxygen, tsari daga rauni zuwa ƙarfi shine kamar haka: chromium, manganese, carbon, silicon, vanadium, titanium, boron, aluminum, zirconium, da calcium. Don haka, ana amfani da alluran ƙarfe da suka haɗa da silicon, manganese, aluminum, da calcium don deoxidation a aikin ƙarfe.
Ana amfani dashi azaman wakili na alloying. Abubuwan da ke haɗawa ba za su iya rage ƙazanta kawai a cikin ƙarfe ba, amma kuma daidaita abubuwan sinadaran karfe. Abubuwan da aka saba amfani da su sun haɗa da silicon, manganese, chromium, molybdenum, vanadium, titanium, tungsten, cobalt, boron, niobium, da dai sauransu. Makin ƙarfe mai ɗauke da abubuwa daban-daban na alloying da abubuwan da ke cikin gami suna da kaddarorin da amfani daban-daban. Ana amfani dashi azaman wakili mai ragewa. Bugu da ƙari, za'a iya amfani da ferrosilicon azaman wakili mai ragewa don samar da ferromolybdenum, ferrovanadium da sauran kayan haɗin ƙarfe. Silicon-chromium gami da silicon-manganese gami za a iya amfani da su azaman rage wakilai don tace matsakaici-ƙananan carbon ferrochromium da matsakaici-ƙananan carbon ferromanganese bi da bi.
A takaice dai, silicon na iya inganta haɓakar elasticity da ƙarfin maganadisu na ƙarfe. Don haka, dole ne a yi amfani da allunan siliki lokacin da ake narkewar ƙarfe na tsari, ƙarfe na kayan aiki, ƙarfe na bazara da siliki don masu canzawa; General karfe ƙunshi 0.15% -0.35% silicon, tsarin karfe ƙunshi 0.40% -1.75% silicon, da kuma kayan aiki karfe ƙunshi Silicon 0.30% -1.80%, spring karfe ƙunshi silicon 0.40% -2.80%, bakin acid-resistant karfe ƙunshi silicon 3.40% -4.00%, karfe mai jure zafi ya ƙunshi silicon 1.00% -3.00%, silicon karfe ya ƙunshi silicon 2% - 3% ko mafi girma. Manganese na iya rage ɓarnar ƙarfe, haɓaka aikin aiki mai zafi na ƙarfe, da haɓaka ƙarfi, tauri da juriya na ƙarfe.
