Na mgbakwunye na iji mee ígwè, a na-ejikwa ferrosilicon dị ka deoxidizer na agbaze nke ígwè magnesium. Usoro nhazi ígwè bụ usoro nke a na-eme ka ígwè a wụrụ awụ na-ekpochapụ ma wepụ ihe ndị na-emerụ ahụ dị ka phosphorus na sọlfọ site na ịfụ ikuku oxygen ma ọ bụ tinye oxidants. N'oge a na-eme nchara sitere na igwe ezi, ọdịnaya oxygen dị na nchara a wụrụ awụ ji nwayọọ nwayọọ na-abawanye, ma FeO na-anọchi anya ya dị na nchara a wụrụ awụ. Ọ bụrụ na ewepụghị ikuku oxygen nke fọdụrụ na nchara na silicon-manganese alloy, enweghị ike ịtụba ya n'ime billet ígwè ruru eru, a pụghịkwa inweta ígwè nwere ezigbo ihe eji arụ ọrụ.
Iji mee nke a, ọ dị mkpa ịgbakwunye ụfọdụ ihe ndị nwere ike na-ejikọta ike na oxygen karịa ígwè, na ndị oxides dị mfe iwepụ na nchara a wụrụ awụ n'ime slag. Dị ka ike njikọ nke ihe dị iche iche dị na nchara a wụrụ awụ na oxygen, usoro site na adịghị ike gaa na nke siri ike bụ nke a: chromium, manganese, carbon, silicon, vanadium, titanium, boron, aluminum, zirconium, na calcium. Ya mere, a na-ejikarị ígwè eme ihe ndị mejupụtara silicon, manganese, aluminum, na calcium maka deoxidation n'ime ígwè.
Ejiri ya dị ka onye na-ahụ maka alloying. Alloying ihe nwere ike ọ bụghị naanị ibelata adịghị ọcha ọdịnaya na ígwè, ma na-edozi chemical mejupụtara nke ígwè. Ihe ndị na-eji alloying eme ihe na-agụnye silicon, manganese, chromium, molybdenum, vanadium, titanium, tungsten, cobalt, boron, niobium, wdg. Nrịgo ígwè nwere ihe dị iche iche alloying na ihe alloy nwere ihe dị iche iche na ojiji. Ejiri ya dị ka onye na-ebelata ihe. Tụkwasị na nke ahụ, a pụrụ iji ferrosilicon mee ihe dị ka onye na-ebelata mmepụta nke ferromolybdenum, ferrovanadium na ígwè ndị ọzọ. Enwere ike iji silicon-chromium alloy na silicon-manganese alloy dị ka ndị na-ebelata ihe na-eme ka carbon ferrochromium na-adịchaghị ala na carbon ferromanganese dị ala n'otu n'otu.
Na nkenke, silicon nwere ike imeziwanye elasticity na magnetik permeability nke ígwè. Ya mere, a ga-eji silicon alloys mee ihe mgbe ị na-agbaze nchara nhazi, ngwá ọrụ ígwè, mmiri ígwè na silicon ígwè maka mgbanwe; ígwè n'ozuzu nwere 0.15% -0.35% silicon, ígwè nhazi nwere 0.40% -1.75% silicon, na ngwá ọrụ ígwè nwere Silicon 0.30% -1.80%, mmiri ígwè nwere silicon 0.40% -2.80%, igwe anaghị agba nchara na-eguzogide ọgwụ nwere silicon 3.40% -4.00%, ígwè na-eguzogide okpomọkụ nwere silicon 1.00% -3.00%, silicon steel nwere silicon 2% - 3% ma ọ bụ karịa. Manganese nwere ike ibelata nbibi nke ígwè, melite arụ ọrụ na-ekpo ọkụ nke ígwè, ma mee ka ike, ike na iyi nguzogide ígwè.
