Ferrosilicon, silicon na ígwè alloy, dị na 45%, 65%, 75% na 90% silicon akara ule.Ojiji ya dị obosara, mgbe ahụ, onye na-emepụta ferrosilicon Anhui Fitech Materials Co., Ltd ga-enyocha ihe eji eme ya kpọmkwem site na isi ihe atọ ndị a.
Nke mbụ, a na-eji ya dị ka deoxidizer na alloying agent na ụlọ ọrụ na-emepụta ígwè.Iji nweta nchara nwere kemịkalụ kemịkalụ ruru eru ma hụ na ọ dị mma, a ga-emerịrị deoxidation na njedebe nke nchara.Njikọ kemịkalụ dị n'etiti silicon na oxygen buru ibu.Ya mere, ferrosilicon bụ ike deoxidizer maka nchara, nke a na-eji maka mmiri ozuzo na mgbasa deoxidation.Ịtinye obere silicon na nchara nwere ike ime ka ike, ike na ngbanwe nke ígwè ahụ dịkwuo mma.
Ya mere, a na-ejikwa ferrosilicon dị ka onye na-ahụ maka alloy mgbe ọ na-agbaze nchara nhazi (nwere silicon 0.40-1.75%), ngwá ọrụ ígwè (nwere silicon 0.30-1.8%), mmiri ígwè (nwere silicon 0.40-2.8%) na silicon ígwè maka transformer (nwere silicon ígwè). nwere silicon 2.81-4.8%).
Tụkwasị na nke ahụ, na ụlọ ọrụ na-emepụta ígwè, ferrosilicon ntụ ntụ nwere ike ịhapụ nnukwu okpomọkụ n'okpuru okpomọkụ dị elu.A na-ejikarị ya dị ka onye na-ekpo ọkụ nke ingot okpu iji meziwanye ogo na mgbake nke ingot.
Nke abuo, a na-eji ya dị ka inoculant na spheroidizing n'ụlọ ọrụ nkedo ígwè.Nkedo ígwè bụ ihe dị mkpa ígwè na ụlọ ọrụ ọgbara ọhụrụ.Ọ dị ọnụ ala karịa ígwè ma dị mfe ịgbaze na agbaze.Ọ nwere ihe nkedo dị oke mma yana ikike ịma jijiji dị mma karịa igwe.Karịsịa nodular nkedo ígwè, ihe eji arụ ọrụ ya na-eru ma ọ bụ na-abịaru nso n'ọrụ igwe nke ígwè.Ịtinye obere ferrosilicon na nkedo ígwè nwere ike igbochi nhazi nke carbide na ígwè ma kwalite ọdịda na spheroidization nke graphite.Ya mere, ferrosilicon bụ ihe dị mkpa inoculant (iji nyere aka precipitate graphite) na spheroidizing ihe na mmepụta nke nodular nkedo ígwè.
Na mgbakwunye, a na-eji ya dị ka onye na-ebelata ihe na-emepụta ferroalloy.Ọ bụghị naanị kemịkalụ kemịkalụ n'etiti silicon na oxygen dị ukwuu, kamakwa ọdịnaya carbon nke silicon ferrosilicon dị elu dị obere.Ya mere, nnukwu silicon ferrosilicon (ma ọ bụ siliceous alloy) bụ ihe na-ebelata mkpokọta na mmepụta nke obere carbon ferroalloy na ụlọ ọrụ ferroalloy.
