Ubudlelwane beekhemikhali phakathi kwe-silicon kunye ne-oksijini buphezulu kakhulu, ngoko ke i-ferrosilicon isetyenziswa njenge-deoxidizer (i-precipitation deoxidation kunye ne-diffusion deoxidation) kwishishini le-steelmaking. Ngaphandle kwensimbi ebilisiwe kunye nentsimbi ebuleweyo, umxholo we-silicon kwintsimbi akufanele ube ngaphantsi kwe-0.10%. I-silicon ayenzi i-carbides kwintsimbi, kodwa ikhona kwisisombululo esiqinileyo kwi-ferrite kunye ne-austenite. I-Silicon inefuthe elinamandla ekuphuculeni amandla esisombululo esiqinileyo kwintsimbi kunye nesantya sokusebenza okubandayo, kodwa kunciphisa ukuqina kunye neplastiki yentsimbi; inomphumo olinganiselayo ekuqineni kwentsimbi, kodwa inokuphucula ukuzinza kunye nokuxhatshazwa kwe-oxidation yensimbi, ngoko ke i-silicon Iron isetyenziswe njenge-agent alloying kwishishini le-steelmaking. I-Silicon nayo ineempawu zokuchasana okukhulu okukhethekileyo, ukungahambi kakuhle kwe-thermal kunye ne-conductivity enamandla yamagnetic. Insimbi iqulethe inani elithile le-silicon, elinokuphucula amandla ombane wentsimbi, ukunciphisa ilahleko ye-hysteresis, kunye nokunciphisa ilahleko yangoku ye-eddy. Intsimbi yombane iqulethe i-2% ukuya kwi-3% yeSi, kodwa idinga i-titanium ephantsi kunye nomxholo we-boron. Ukongeza i-silicon kwintsimbi yokuphosa kunokuthintela ukubunjwa kwee-carbides kunye nokukhuthaza imvula kunye ne-spheroidization ye-graphite. I-Silicon-magnesia iron yinto eqhelekileyo esetyenziswa kwi-spheroidizing agent. I-Ferrosilicon equkethe i-barium, i-zirconium, i-strontium, i-bismuth, i-manganese, umhlaba onqabileyo, njl. I-high-silicon ferrosilicon yi-arhente yokunciphisa esetyenziswa kwishishini le-ferroalloy ukuvelisa i-ferroalloys ephantsi kwekhabhoni. I-Ferrosilicon powder equkethe malunga ne-15% ye-silicon (ubungakanani be-particle <0.2mm) isetyenziswe njenge-agent enzima kwi-medium media processing processing.
Isixhobo sokuvelisa i-ferrosilicon sisithando sombane sokunciphisa i-arc. Umxholo we-silicon we-ferrosilicon ulawulwa yi-dosage ye-iron ekrwada. Ukongeza ekusebenziseni i-silica ecocekileyo kunye ne-agent yokunciphisa ukuvelisa i-ferrosilicon ephezulu yokucoca, ukucocwa ngaphandle kwesithando somlilo kuyafuneka ukunciphisa ukungcola okufana ne-aluminium, i-calcium, kunye nekhabhoni kwi-alloy. Ukuhamba kwenkqubo yokuvelisa i-ferrosilicon kuboniswe kuMfanekiso 4. I-Ferrosilicon equkethe i-Si≤ I-65% inokunyibilika kwisithando sombane esivaliweyo. I-Ferrosilicon ene-Si ≥ 70% inyibilika kwisithando sombane esivulekileyo okanye i-semi-closed yombane yombane.
