Ukuhlobana kwamakhemikhali phakathi kwe-silicon nomoya-mpilo kuphezulu kakhulu, ngakho i-ferrosilicon isetshenziswa njenge-deoxidizer (i-precipitation deoxidation kanye ne-diffusion deoxidation) embonini yokwenza insimbi. Ngaphandle kwensimbi ebilisiwe nensimbi ebulewe kancane, okuqukethwe kwe-silicon ensimbi akufanele kube ngaphansi kuka-0.10%. I-silicon ayenzi ama-carbides ngensimbi, kodwa ikhona kusisombululo esiqinile ku-ferrite ne-austenite. I-silicon inomthelela oqinile ekuthuthukiseni amandla esixazululo esiqinile ensimbi kanye nezinga lokuqina lokuqina kokusebenza okubandayo, kodwa inciphisa ukuqina nokuqina kwensimbi; inomthelela olinganiselayo ekuqineni kwensimbi, kodwa ingathuthukisa ukuzinza kwe-teering kanye nokumelana ne-oxidation yensimbi, ngakho-ke i-silicon Iron isetshenziswa njenge-ejenti ye-alloying embonini yokwenza insimbi. I-silicon nayo inezici zokumelana okukhulu okuqondile, ukungahambi kahle kwe-thermal kanye ne-conductivity enamandla kazibuthe. Insimbi iqukethe inani elithile le-silicon, engathuthukisa amandla kazibuthe ensimbi, inciphise ukulahleka kwe-hysteresis, futhi inciphise ukulahlekelwa kwamanje kwe-eddy. Insimbi kagesi iqukethe u-2% kuya ku-3% Si, kodwa idinga i-titanium ephansi kanye nokuqukethwe kwe-boron. Ukwengeza i-silicon ensimbini kungavimbela ukwakheka kwama-carbides futhi kukhuthaze imvula kanye ne-spheroidization ye-graphite. I-silicon-magnesia iron iyi-ejenti evame ukusetshenziswa e-spheroidizing. I-Ferrosilicon equkethe i-barium, i-zirconium, i-strontium, i-bismuth, i-manganese, umhlaba ongavamile, njll. isetshenziswa njenge-inoculant ekukhiqizeni insimbi ekhonjiwe. I-high-silicon ferrosilicon iyi-ejenti yokunciphisa esetshenziswa embonini ye-ferroalloy ukukhiqiza ama-ferroalloys anekhabhoni ephansi. I-Ferrosilicon powder equkethe cishe i-silicon engu-15% (usayizi wezinhlayiyana <0.2mm) isetshenziswa njenge-ejenti enesisindo ekucubunguleni amaminerali esindayo.
Imishini yokukhiqiza i-ferrosilicon iyisithando somlilo sikagesi sokunciphisa i-arc esingaphansi kwamanzi. Okuqukethwe kwe-silicon ye-ferrosilicon kulawulwa umthamo wezinto ezingavuthiwe zensimbi. Ngaphezu kokusebenzisa i-silica ehlanzekile kanye nama-ejenti okunciphisa ukukhiqiza i-ferrosilicon ehlanzekile, ukucwenga ngaphandle kwesithando somlilo kuyadingeka futhi ukunciphisa ukungcola okufana ne-aluminium, i-calcium, ne-carbon ku-alloy. Ukugeleza kwenqubo yokukhiqiza i-ferrosilicon kuboniswa kuMfanekiso 4. I-Ferrosilicon equkethe i-Si≤ I-65% ingancibilika esithandweni somlilo esivaliwe. I-Ferrosilicon ene-Si ≥ 70% incibilikiswa esithandweni sikagesi esivulekile noma esithandweni sikagesi esivalwe kancane.
