Kugwirizana kwamankhwala pakati pa silicon ndi okosijeni ndikwambiri, kotero ferrosilicon imagwiritsidwa ntchito ngati deoxidizer (kutulutsa mpweya komanso kutulutsa mpweya) m'makampani opanga zitsulo. Kupatula zitsulo zowiritsa ndi zitsulo zophikidwa pang'ono, zomwe zili mu silicon muzitsulo siziyenera kukhala zosachepera 0.10%. Silicon samapanga ma carbides muzitsulo, koma amapezeka muzitsulo zolimba mu ferrite ndi austenite. Silikoni imakhudza kwambiri kulimbitsa mphamvu ya njira yolimba muzitsulo komanso kuzizira kogwira ntchito mopanda kuuma, koma kumachepetsa kulimba ndi pulasitiki yachitsulo; ali ndi zotsatira zolimbitsa pa kuuma kwa zitsulo, koma zimatha kupititsa patsogolo kukhazikika kwa kutentha ndi kukana kwa okosijeni kwa chitsulo, kotero silicon Iron imagwiritsidwa ntchito ngati alloying agent mumakampani opanga zitsulo. Silicon ilinso ndi mawonekedwe a kukana kwakukulu kwapadera, kusayenda bwino kwamafuta ndi maginito amphamvu. Chitsulo chimakhala ndi silicon yambiri, yomwe imatha kupititsa patsogolo mphamvu yamaginito yachitsulo, kuchepetsa kutaya kwa hysteresis, ndi kuchepetsa kuwonongeka kwa eddy panopa. Chitsulo chamagetsi chimakhala ndi 2% mpaka 3% Si, koma chimafuna titaniyamu yotsika ndi boron. Kuonjezera silicon kuponya chitsulo kungalepheretse mapangidwe a carbides ndikulimbikitsa mpweya ndi spheroidization wa graphite. Silicon-magnesia iron ndi spheroidizing agent yomwe imagwiritsidwa ntchito kwambiri. Ferrosilicon yomwe ili ndi barium, zirconium, strontium, bismuth, manganese, nthaka yosowa, ndi zina zotero zimagwiritsidwa ntchito ngati inoculant pakupanga chitsulo. High-silicon ferrosilicon ndi chochepetsera chomwe chimagwiritsidwa ntchito m'makampani a ferroalloy kupanga ma ferroalloys a carbon otsika. Ferrosilicon ufa munali za 15% pakachitsulo (tinthu kukula <0.2mm) ntchito monga wothandizila zolemera mu heavy media mchere processing.
Zida zopangira ferrosilicon ndi ng'anjo yamagetsi yomira pansi pa arc. Zomwe zili mu silicon mu ferrosilicon zimayendetsedwa ndi mlingo wa zipangizo zachitsulo. Kuphatikiza pa kugwiritsa ntchito silika koyera ndi kuchepetsa zopangira kupanga ferrosilicon yapamwamba kwambiri, kuyenga kunja kwa ng'anjo kumafunikanso kuchepetsa zonyansa monga aluminium, calcium, ndi carbon mu alloy. Njira yopangira ferrosilicon ikuwonetsedwa mu Chithunzi 4. Ferrosilicon yomwe ili ndi Si≤ 65% ikhoza kusungunuka mu ng'anjo yotsekedwa yamagetsi. Ferrosilicon yokhala ndi Si ≥ 70% imasungunuka mung'anjo yamagetsi yotseguka kapena ng'anjo yamagetsi yotsekedwa ndi theka.
